library under +Acorn C/C++ under Acorn's RISC OS 3.10 or above. Subsequent pathnames will +use the Acorn format: The full-stop or period character is a pathname +delimeter, and the slash character is not interpreted; the reverse position +from Unix. Thus "libtiff/tif_acorn.c" becomes "libtiff.tif_acorn/c". + +This support was contributed by Peter Greenham. +(peterg@angmulti.demon.co.uk). + +Installing LibTIFF: + +LIBTIFF uses several files which have names longer than the normal RISC OS +maximum of ten characters. This complicates matters. Maybe one day Acorn will +address the problem and implement long filenames properly. Until then this +gets messy, especially as I'm trying to do this with obeyfiles and not have +to include binaries in this distribution. + +First of all, ensure you have Truncate configured on (type *Configure +Truncate On) Although it is, of course, preferable to have long filenames, +LIBTIFF can be installed with short filenames, and it will compile and link +without problems. However, getting it there is more problematic. +contrib.acorn.install is an installation obeyfile which will create a normal +Acorn-style library from the source (ie: with c, h and o folders etc.), but +needs the distribution library to have been unpacked into a location which is +capable of supporting long filenames, even if only temporarily. + +My recommendation, until Acorn address this problem properly, is to use Jason +Tribbeck's LongFilenames , or any other working system that gives you long +filenames, like a nearby NFS server for instance. + +If you are using Longfilenames, even if only temporarily to install LIBTIFF, +unpack the TAR into a RAMDisc which has been longfilenamed (ie: *addlongfs +ram) and then install from there to the hard disk. Unfortunately +Longfilenames seems a bit unhappy about copying a bunch of long-named files +across the same filing system, but is happy going between systems. You'll +need to create a ramdisk of about 2Mb. + +Now you can run the installation script I've supplied (in contrib.acorn), +which will automate the process of installing LIBTIFF as an Acorn-style +library. The syntax is as follows: + +install + +Install will then create and put the library in there. For +example, having used LongFilenames on the RAMDisk and unpacked the library +into there, you can then type: + +Obey RAM::RamDisc0.$.contrib.acorn.install RAM::RamDisc0.$ ADFS::4.$.LIBTIFF + +It doesn't matter if the destination location can cope with long filenames or +not. The filenames will be truncated if necessary (*Configure Truncate On if +you get errors) and all will be well. + +Compiling LibTIFF: + +Once the LibTIFF folder has been created and the files put inside, making the +library should be just a matter of running 'SetVars' to set the appropriate +system variables, then running 'Makefile'. + +OSLib + +OSLib is a comprehensive API for RISC OS machines, written by Jonathan +Coxhead of Acorn Computers (although OSLib is not an official Acorn product). +Using the OSLib SWI veneers produces code which is more compact and more +efficient than code written using _kernel_swi or _swi. The Acorn port of +LibTIFF can take advantage of this if present. Edit the Makefile and go to +the Static dependencies section.

Since DJGPP defines the unix flag, +I have created a port.h instead of putting the necessary defines into +tiffcomp.h. Makefiles are included for the top level and the libtiff and +tools directories. + +All you have to do is copy the files into the respective directories and run +make. If you want, you can use the conf.bat to do that for you, make sure that +the file is stored with MSDOS text EOL-convention (CR/LF), otherwise the +command.com will not do anything (if you used unzip, use the -a option, +otherwise edit the file and save it again). + +Note that you probably will not be able to built the library with the v1.x +versions of djgpp, due to two problems. First, the top makefile calls a +sub-make for each directory and you are likely to run out of memory, since +each recursive invocation of a djgpp v1.x program requires about 130k, to +avoid that, you can enter the directories manually and call make (well, there +are only two dirs). The 2nd problem is that djgpp 1.x doesn't call the +coff2exe (stubify) program when creating an executable. This means that all +programs compiled are not converted to exe and consequently are not available +for calling directly. For the tools directory, you can just call coff2exe for +each program after make finishes, but in the libtiff directory, a few programs +are created during the make process that have to be called for make to +continue (e.g. mkg3states). Make will probably report an error at each +such stage. To fix that, either add a coff2exe call before each program is +called or call coff2exe manually and rerun make (there 2-3 such programs). + +Alexander Lehmann + diff --git a/contrib/iptcutil/Makefile b/contrib/iptcutil/Makefile new file mode 100755 index 0000000..54befc9 --- /dev/null +++ b/contrib/iptcutil/Makefile @@ -0,0 +1,12 @@ +CC=gcc +CFLAGS= +iptcutil: iptcutil.c + $(CC) $(CFLAGS) -o iptcutil iptcutil.c + +clean: + rm iptcutil *~ + +all: iptcutil + + + diff --git a/contrib/iptcutil/iptcutil.c b/contrib/iptcutil/iptcutil.c new file mode 100755 index 0000000..f25ada7 --- /dev/null +++ b/contrib/iptcutil/iptcutil.c @@ -0,0 +1,920 @@ +#include +#include +#include +#ifdef WIN32 +#include +#endif +#include +#include +#include + +#ifdef WIN32 +#define STRNICMP strnicmp +#else +#define STRNICMP strncasecmp +#endif + +typedef struct _tag_spec +{ + short + id;

It allows + you extract tokens one at a time from a string of characters. The + characters used for white space, for break characters, and for quotes + can be specified. Also, characters in the string can be preceded by + a specifiable escape character which removes any special meaning the + character may have. + + There are a lot of formal parameters in this subroutine call, but + once you get familiar with them, this routine is fairly easy to use. + "#define" macros can be used to generate simpler looking calls for + commonly used applications of this routine. + + First, some terminology: + + token: used here, a single unit of information in + the form of a group of characters. + + white space: space that gets ignored (except within quotes + or when escaped), like blanks and tabs. in + addition, white space terminates a non-quoted + token. + + break character: a character that separates non-quoted tokens. + commas are a common break character. the + usage of break characters to signal the end + of a token is the same as that of white space, + except multiple break characters with nothing + or only white space between generate a null + token for each two break characters together. + + for example, if blank is set to be the white + space and comma is set to be the break + character, the line ... + + A, B, C , , DEF + + ... consists of 5 tokens: + + 1) "A" + 2) "B" + 3) "C" + 4) "" (the null string) + 5) "DEF" + + quote character: a character that, when surrounding a group + of other characters, causes the group of + characters to be treated as a single token, + no matter how many white spaces or break + characters exist in the group. also, a + token always terminates after the closing + quote. for example, if ' is the quote + character, blank is white space, and comma + is the break character, the following + string ... + + A, ' B, CD'EF GHI + + ... consists of 4 tokens: + + 1) "A" + 2) " B, CD" (note the blanks & comma) + 3) "EF" + 4) "GHI" + + the quote characters themselves do + not appear in the resultant tokens. the + double quotes are delimiters i use here for + documentation purposes only. + + escape character: a character which itself is ignored but + which causes the next character to be + used as is. ^ and \ are often used as + escape characters. an escape in the last + position of the string gets treated as a + "normal" (i.e., non-quote, non-white, + non-break, and non-escape) character. + for example, assume white space, break + character, and quote are the same as in the + above examples, and further, assume that + ^ is the escape character. then, in the + string ... + + ABC, ' DEF ^' GH' I ^ J K^ L ^ + + ... there are 7 tokens: + + 1) "ABC" + 2) " DEF ' GH" + 3) "I" + 4) " " (a lone blank) + 5) "J" + 6) "K L" + 7) "^" (passed as is at end of line) + + + OK, now that you have this background, here's how to call "tokenizer": + + result=tokenizer(flag,token,maxtok,string,white,break,quote,escape, + brkused,next,quoted) + + result: 0 if we haven't reached EOS (end of string), and + 1 if we have (this is an "int"). + + flag: right now, only the low order 3 bits are used. + 1 => convert non-quoted tokens to upper case + 2 => convert non-quoted tokens to lower case + 0 => do not convert non-quoted tokens + (this is a "char"). + + token: a character string containing the returned next token + (this is a "char[]"). + + maxtok: the maximum size of "token". characters beyond + "maxtok" are truncated (this is an "int"). + + string: the string to be parsed (this is a "char[]"). + + white: a string of the valid white spaces. example: + + char whitesp[]={" \t"}; + + blank and tab will be valid white space (this is + a "char[]"). + + break: a string of the valid break characters. example: + + char breakch[]={";,"}; + + semicolon and comma will be valid break characters + (this is a "char[]"). + + IMPORTANT: do not use the name "break" as a C + variable, as this is a reserved word in C. + + quote: a string of the valid quote characters. an example + would be + + char whitesp[]={"'\""); + + (this causes single and double quotes to be valid) + note that a token starting with one of these characters + needs the same quote character to terminate it. + + for example, + + "ABC ' + + is unterminated, but + + "DEF" and 'GHI' + + are properly terminated. note that different quote + characters can appear on the same line; only for + a given token do the quote characters have to be + the same (this is a "char[]"). + + escape: the escape character (NOT a string ... only one + allowed). use zero if none is desired (this is + a "char"). + + brkused: the break character used to terminate the current + token. if the token was quoted, this will be the + quote used. if the token is the last one on the + line, this will be zero (this is a pointer to a + "char"). + + next: this variable points to the first character of the + next token. it gets reset by "tokenizer" as it steps + through the string. set it to 0 upon initialization, + and leave it alone after that. you can change it + if you want to jump around in the string or re-parse + from the beginning, but be careful (this is a + pointer to an "int"). + + quoted: set to 1 (true) if the token was quoted and 0 (false) + if not. you may need this information (for example: + in C, a string with quotes around it is a character + string, while one without is an identifier). + + (this is a pointer to a "char"). +*/ + +/* states */ + +#define

Be sure to + use the native libraries as well. NOTE: if anyone cooks + up an equivalent script for PPC, send it to me and I'll include + it with the rest of the package. + +3. Open the file Makefile.script with an AppleScript Editor + and change the PATHNAME variable to point to your + top-level TIFF directory + +4. Run the Script. It will do the following things: + + 4a. Prompt you for the current location of the CodeWarrior 68K + program. + + 4b. Create the source file "tif_fax3sm.c": + + i) Build the project CW project mkg3states.cw.

In my applications I had already read a TIFF or other format +file in to memory and did not want to waste I/O writing it out again +for libtiff's benefit. I therefore constructed a set of functions to +pass up to TIFFClientOpen to simulate a file in memory. I have attached +my mfs (memory file system) source code for you to use or junk, as you +see fit. :-) + +Once again, thanks very much for making my life simpler. + +Best Regards, + +Mike Johnson. diff --git a/contrib/pds/readme b/contrib/pds/readme new file mode 100755 index 0000000..47db5f3 --- /dev/null +++ b/contrib/pds/readme @@ -0,0 +1,90 @@ +Date: Fri, 01 Aug 1997 20:14:52 MDT +To: Sam Leffler + +From: "Conrad J.

If you think they would make good additions to the +TIFF library, I'd be happy to clean them up more, document them more, +and/or integrate them with the latest version of the TIFF library, but I +figured I'd see if you were interested in using them before I went to +all that trouble. + +TIFF Image Iterator +------------------- +Your ReadRGBA() routine works well for reading many different formats +(TILED, STIP, compressed or not, etc.) of the most basic types of data +(RGB, 8-bit greyscale, 8-bit colormapped) into an SGI-style data array, +and serves as a good template for users with other needs. I used it as +an exmaple of how to make an iterator which, rather than fill a data +array, calls an arbitrary user-supplied callback function for each +"chunk" of data - that "chunk" might be a strip or a tile, and might +have one sample-per-pixel or two, and might be 8-bit data or 16-bit or +24-bit. The callback function can do whatever it wants with the data - +store it in a big array, convert it to RGBA, or draw it directly to the +screen. I was able to use this iterator to read 16-bit greyscale and 32- +and 64-bit floating point data, which wasn't possible with ReadRGBA(). + +I have tested this routine with 8- and 16-bit greyscale data as well as +with 32- and 64-bit floating point data. I believe nearly all of our +data is organized in strips, so actually I'd appreciate it if you had +some tiled images that I could test it with. + +It should certainly be possible and would be cleanest to reimplement +ReadRGBA() in terms of the image iterator, but I haven't done that. + + +Private Sub-Directory Read/Write +-------------------------------- +TIFF-PL is a Phillips Laboratory extension to the TIFF tags that allows +us to store satellite imaging-specific information in a TIFF format, +such as the satellite's trajectory, the imaging time, etc. In order to +give us the flexibility to modify the tag definitions without getting +approval from the TIFF committee every time, we were given only three +TIFF tags - a PL signature, a PL version number, and PL directory +offset, which lists the position in the file at which to find a private +sub-directory of tags-value pairs. So I wrote two routines: +TIFFWritePrivateDataSubDirectory(), which takes a list of tags and a +"get" function and writes the tag values into the TIFF file, returning +the offset within the file at which it wrote the directory; and +TIFFReadPrivateDataSubDirectory(), which takes an offset, a list of +tags, and a "set" function and reads all the data from the private +directory. The functions themselves are pretty simple. (The files are +huge because I had to basically copy all of the tif_dirread.c and +tif_dirwrite.c files in order to access the various fetching routines +which were all declared static and therefore inaccessible in the TIFF +library.) + + +I'm including the four source files (tif_imgiter.h, tif_imgiter.c, +tif_pdsdirread.c, tif_pdsdirwrite.c) in case you want to take a look at +them. I can also send you some sample code that uses them if you like. +If you're interested in having them incorporated into the standard TIFF +library, I'd be happy to do that integration and clean up and document +the routines. (For example, I've already realized that instead of +limiting the SEP callback function to three bands (R,G,B) it should take +an array to enable the handling of n-banded multi-spectral data...) If +not, I'll just leave them as they are, since they work fine for us now. + +Holler if you have any questions. + +-- Conrad +__________________________________________________________________ + Capt Conrad J.

I was rushing to get home to +dinner on Friday and the material for you was the last loose end I had to +deal with. Excuses aside ... + +The goal of the adaptation of libtiff to Win32 was to replace only one +environment-specific code module and to make minimal changes to header +files. tif_win32.c required one addition to tiffio.h (the +DECLARE_HANDLE line, which is probably a better way to typedef thandle-t +under Windows 3.1 as well); it also required the addition of pv_map_handle +to the tiff structure and the conditional definition of the +TIFFUnmapFileContents macro in tiffiop.h (this because Win32 uses a handle +and a pointer in mapping memory, and I needed to save both). + +Additionally, I made a general style change to tiffio.h. If tiffio.h is +included by a client, which does not include tiffiop.h, then ANSI compilers +warn about the typedef of TIFF to a non-existent structure. To avoid this, +I changed the typedef of TIFF in this case to void. + +I also made a style change in the tiff structure. All references to tif_fd +in the library treat it as int, yet the tif_fd member itself is short. I +changed this member to int and added the reserved member to maintain +32-bit structure member alignment in a 32 bit environment. [ At cost of +4 more bytes in an already bloated structure! :-) ] As long as fd's are +less than 64k, the old member works; this is not the case in Win32, and is +not generally a safe assumption. + +The module dllshell.c and the file libtiff.def are not specific to the +functionality of libtiff; they are used to make a Win32 dynamic link +library, and would be best packaged with a Win32 makefile, which I have +not yet perfected. I will, however, commit to a Borland and Microsoft C +makefile for libtiff; perhaps these two could be combined with the +makefile for the _next_ (!) release of libtiff when it is ready. + +Once again, sorry for the confused message on Friday. I hope that at +least tif_w32 and the tiffio.h and tiffiop.h diffs will be useful for +this release. + +Regards, +Scott Wagner (wagner@itek.com) +Itek Graphix +Rochester, NY diff --git a/contrib/win95/Makefile.w95 b/contrib/win95/Makefile.w95 new file mode 100755 index 0000000..3e81fc2 --- /dev/null +++ b/contrib/win95/Makefile.w95 @@ -0,0 +1,134 @@ +# $Header: /usr/people/sam/tiff/libtiff/RCS/Makefile.w95,v 1.2 1994/11/28 +06:13:31 sam Exp $ +# +# Tag Image File Format Library +# +# Copyright (c) 1988, 1989, 1990, 1991, 1992 Sam Leffler +# Copyright (c) 1991, 1992 Silicon Graphics, Inc. +# +# Permission to use, copy, modify, distribute, and sell this software and +# its documentation for any purpose is hereby granted without fee, provided +# that (i) the above copyright notices and this permission notice appear in +# all copies of the software and related documentation, and (ii) the names of +# Sam Leffler and Silicon Graphics may not be used in any advertising or +# publicity relating to the software without the specific, prior written +# permission of Sam Leffler and Silicon Graphics. +# +# THE SOFTWARE IS PROVIDED "AS-IS" AND WITHOUT WARRANTY OF ANY KIND, +# EXPRESS, IMPLIED OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY +# WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. +# +# IN NO EVENT SHALL SAM LEFFLER OR SILICON GRAPHICS BE LIABLE FOR +# ANY SPECIAL, INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND, +# OR ANY DAMAGES WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, +# WHETHER OR NOT ADVISED OF THE POSSIBILITY OF DAMAGE, AND ON ANY THEORY OF +# LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE +# OF THIS SOFTWARE. +# +# This Makefile is for use with microsoft nmake version 1.50 and +# Microsoft 32-bit C/C++ Compiler 9.00 +# +DESTDIR=. +# +IPATH= -I. +CONF_LIBRARY=$(NULL) +COPTS= -Oxa -DBSDTYPES -Zd +CFLAGS= $(COPTS) $(CONF_LIBRARY) +# +INCS= tiff.h tiffio.h +SRCS= tif_aux.c \ + tif_close.c \ + tif_codec.c \ + tif_compress.c \ + tif_dir.c \ + tif_dirinfo.c \ + tif_dirread.c \ + tif_dirwrite.c \ + tif_dumpmode.c \ + tif_error.c \ + tif_getimage.c \ + tif_jpeg.c \ + tif_flush.c \ + tif_lzw.c \ + tif_next.c \ + tif_open.c \ + tif_packbits.c \ + tif_predict \ + tif_print.c \ + tif_read.c \ + tif_swab.c \ + tif_strip.c \ + tif_thunder.c \ + tif_tile.c \ + tif_version.c \ + tif_warning.c \ + tif_write.c \ + tif_win32.c + + +OBJS= tif_aux.obj \ + tif_close.obj \ + tif_codec.obj \ + tif_compress.obj \ + tif_dir.obj \ + tif_dirinfo.obj \ + tif_dirread.obj \ + tif_dirwrite.obj \ + tif_dumpmode.obj \ + tif_error.obj \ + tif_getimage.obj \ + tif_jpeg.obj \ + tif_flush.obj \ + tif_lzw.obj \ + tif_next.obj \ + tif_open.obj \ + tif_packbits.obj \ + tif_predict.obj \ + tif_print.obj \ + tif_read.obj \ + tif_swab.obj \ + tif_strip.obj \ + tif_thunder.obj \ + tif_tile.obj \ + tif_version.obj \ + tif_warning.obj \ + tif_write.obj \ + tif_win32.obj + + + +ALL= libtiff.lib + +all: $(ALL) + +%.obj : %.c + $(CC) $(CFLAGS) -c $*.c + + +#.INCLUDE .IGNORE : depend + +libtiff.lib: $(OBJS) + - del libtiff.lib + lib /OUT:libtiff.lib $(OBJS) + + +#To include fax3 support, you need to modify mkg3states.c so it could run +#under windows 95 or NT.

I made the makefile.nt based on Philippe +Tenenhaus' makefile.w95 file. Since I want my stuff to be a pure +console application running on WinNT, Dave Dyer's makefile for WINNT is +not good for me since it is for Windows applications. + +I used the tif_msdos.c file instead of the tif_win32.c in the $(OBJS) +list because tif_win32.c is not a pure console program, it includes +some function calls such as MessageBox etc which requires windows +application library ($winslib as defined in ). + +unlike Philippe Tenenhaus' makefile.w95 file, this makefile.nt does +support fax3 stuff. And to make the mkg3states.exe,the getopt.obj is +needed. "getopt" package is ATT public domain source for getopt(3). +Also you need to inlcude the g3states.h in tif_fax.c fileand modify the +tif_fax3.h to delete the external declaration of FFFaxMainTable,

+ +Building the Software Distribution +

+ + + +
+ +This chapter contains step-by-step instructions on how to configure +and build the TIFF software distribution. +The software is most easily built on a UNIX system, but with a little +bit of work it can easily be built and used on other non-UNIX platforms. + +

Building on a UNIX System

 + +To build the software on a UNIX system +you need to first run the configure shell script +that is located in the top level of the source directory. +This script probes the target system for necessary tools and functions +and constructs a build environment in which the software may be +compiled. +Once configuration is done, you simply run make + to build the software +and then make install to do the installation; for example: + +
    +hyla% cd tiff-v3.4beta099
+hyla% ./configure
+    ...lots of messages...
+hyla% make
+    ...lots of messages...
+hyla# make install
+
+ +In general, the software is designed such that the following should +be ``make-able'' in each directory: + +
    +make [all]	build stuff
+make install	build&install stuff
+make clean	remove .o files and cruft, but not executables
+make clobber	remove everything that can be recreated
+make distclean	remove absolutely everything that can be recreated
+
+ +Note that after running "make clobber" or +"make distclean" the configure script must +be run again to create the Makefiles and other make-related files. + +

Build Trees

 + +There are two schemes for configuring and building the software. +If you intend to build the software for only one target system, you +can configure the software so that it is built in the same directories +as the source code. + +
    +hyla% cd tiff-v3.4beta099
+hyla% ls
+COPYRIGHT       VERSION         config.sub      dist            man
+Makefile.in     config.guess    configure       html            port
+README          config.site     contrib         libtiff         tools
+hyla% ./configure
+
+ +

+Otherwise, you can configure a build tree that +is parallel to the source tree hierarchy but which contains only +configured files and files created during the build procedure. + +

    +hyla% cd tiff-v3.4beta099
+hyla% mkdir obj obj/mycpu
+hyla% cd obj/mycpu
+hyla% ../../configure
+
+ +This second scheme is useful for: + +
    +
  • building multiple targets from a single source tree +
  • building from a read-only source tree (e.g. if you receive + the distribution on CD-ROM) +
+ +

Configuration Files

 + +The configuration process is critical to the proper compilation, +installation, and operation of the software. +The configure script runs a series of tests to +decide whether or not the target system +supports required functionality and, if it does not, whether it +can emulate or workaround the missing functions. +This procedure is fairly complicated and, due to the nonstandard +nature of most UNIX systems, prone to error. +The first time that you configure the software for use you should +check the output from the configure script and look for anything +that does not make sense for your system. +A sample configure run is shown below together with an explanation +of some of the work that is done. + +

+A second function of the configure script is to set the default +configuration parameters for the software. +Of particular note are the directories where the software is to be +installed. +By default the software is installed in the /usr/local hierarchy. +To change this behaviour the appropriate parameters can be +specified either: +

    +
  • on the command line to configure, +
  • in a site-wide configuration file, or +
  • in a target-specific configuration file. +
+configure reads any site-wide configure file first, and +then any target-specific configuration file. +This permits target-specific definitions to override +site-wide definitions. + +

+Site-wide configuration files are named +config.site and are automatically searched for first +in any directory specified on the command line to configure +(using the -site option), or if that fails, in +the directory in in which the configure script is located. + +

+Target-specific configuration files are named config.local +and are looked for first in the top-level configuration directory, +or, if that fails, in the directory in which the configure script +is located. + +

+Configuration files are just shell scripts that define +shell variables that control the configuration process. +For example, the following file might be used on a BSDI system to +configure the software for installation in the /usr/contrib area. + +

+#
+# Parameters suitable for BSDI 1.1
+#
+DIR_BIN="/usr/contrib/bin"		# directory for client apps
+DIR_LIB="/usr/contrib/lib"		# directory for libraries
+DIR_MAN="/usr/contrib/man"		# directory for manual pages
+
+ +

+For a complete list of the possible configuration parameters look +at the sample config.site file provided in the distribution; the +section below describes some of the more important parameters. + +

Configuring Optional Packages/Support

+ +The TIFF software comes with several packages that are installed only +as needed, or only if specifically configured at the time +the configure script is run. Packages can be configured in a +config.site or config.local file, or by using a +-with-<PACKAGE> option when invoking configure; +e.g. configure -with-AFM. + +
+
DSO Support +
The DSO support controls whether or not to +configure the software +to build a Dynamic Shared Object for the TIFF library. +Use of DSOs can significantly reduce the disk space needed for +users of the TIFF software. +If DSOs are not used then the code is statically linked into +each application that uses it. +By default this support is configured only if the system appears +to suport DSOs in a way that fits into the normal build scheme +(auto). +If DSO support is explicitly enabled and there is no +support for using DSOs in the expected way then DSOs are not used. + +

+

JPEG Support +
The JPEG package enables support for the handling +of TIFF images with JPEG-encoded data. +Support for JPEG-encoded data requires the Independent JPEG Group (IJG) +libjpeg distribution; this software is available at +ftp.uu.net:/graphics/jpeg/. +If JPEG support is enabled the DIRS_LIBINC and DIR_JPEGLIB +parameters should also be set (see below). +By default JPEG support is not configured. + +

+

ZIP Support +
The ZIP support enables support for the handling +of TIFF images with deflate-encoded data. +Support for deflate-encoded data requires the freely available +zlib distribution written by Jean-loup Gailly and Mark Adler; +this software is available at +ftp.uu.net:/pub/archiving/zip/zlib/ +(or try quest.jpl.nasa.gov:/beta/zlib/). +If ZIP support is enabled the DIRS_LIBINC and DIR_GZLIB +parameters should also be set (see below). +By default this package is not configured. + +
+ +

A Sample Configuration Session

 + +This section shows a sample configuration session and describes +the work done. The session is shown indented in a fixed width +font with user-supplied input in a bold font. +Comments are shown in a normal or italic font. +This session was collected on a 486 machine running BSDI 1.1. + +
    
+wullbrandt% mkdir tiff
+wullbrandt% cd tiff
+wullbrandt% ln -s /hosts/oxford/usr/people/sam/tiff src
+
+ +A build tree separate from the source tree is used here. +In fact, in this case the distribution is accessed from +a read-only NFS-mounted filesystem. + +
    
+wullbrandt% src/configure

+Reading local parameters from config.local.
+Gosh, aren't you lucky to have a i386-unknown-bsdi1.1 system!
+
+ +Note that configure announces the distribution version and the +deduced target configuration (i386-unknown-bsdi1.1 here). + +

A specific compiler may be requested +by setting the CC environment variable to the appropriate +pathname, by supplying the parameter on the command line, e.g. +-with-CC=gcc, or by setting CC in a configuration +file. + +

+ +Note that an ANSI C compiler is required to build the software. +If a C compiler requires options to enable ANSI C compilation, they +can be specified with the ENVOPTS parameter. + +

+Once a compiler is selected configure checks to see +if the compiler accepts a -g option to enable the generation + of debugging symbols, and +if the compiler includes an ANSI C preprocessor. + +

    
+Using /usr/ucb/make to configure the software.
+
+ +Next various system-specific libraries that may or may not be needed +are checked for (none are needed in this case). +If your system requires a library that is not +automatically included it can be specified by setting the +MACHDEPLIBS parameter. + +

Creating port.h. +The port.h file is included by all the C code +in the library (but not the tools). +It includes definitions for functions and type +definitions that are missing from system include files, #defines +to enable or disable system-specific functionality, and other +odds and ends. + +

    
+Creating libtiff/port.h with necessary definitions.
+... using LSB2MSB bit order for your i386 cpu
+... using big-endian byte order for your i386 cpu
+... configure use of mmap for memory-mapped files
+... O_RDONLY is in <fcntl.h>
+... using double for promoted floating point parameters
+... enabling use of inline functions
+Done creating libtiff/port.h.
+
+ +This file can take a long time to create so configure +generates the file only when it is needed, either because the +file does not exist or because a different target or compiler +is to be used. +Note that running "make distclean" in the top-level directory +of the build tree will remove the port.h file (along +with all the other files generated by configure). + +

Selecting emulated library functions. +Certain library functions used by the tools are not present on all systems +and can be emulated using other system functionality. +configure checks for the presence of such functions and if they are +missing, will configure emulation code from the port directory +to use instead. Building the TIFF +software on unsupported systems may require +adding to the code to the port directory. + +

    
+Checking system libraries for functionality to emulate.
+Done checking system libraries.
+
+ +If a routine must be emulated and configure does not automatically +check for it, the routine name can be specified using the PORTFUNCS +parameter. To add emulation support for a new function foo, +create a file port/foo.c that contains the emulation code +and then set PORTFUNCS=foo in a configuration file or modify +the configure script to automatically check for the missing function. + +
    
+Checking for Dynamic Shared Object (DSO) support.
+Done checking for DSO support.
+
+ +If the DSO package is enabled (DSO=auto or +DSO=yes), then +configure will verify the system and compiler are capable of +constructing SVR4-style DSO's in the expected way. Note that +while a system may support DSO's the compiler may not be +capable of generating the required position-independent +code and/or the compiler may not pass the needed options +through to the loader. + +

Selecting utility programs. +configure locates various system utility programs that are +used during installation of the software. + +

    
+Selecting programs used during installation.
+Looks like mv supports the -f option to force a move.
+Looks like /bin/ln supports the -s option to create a symbolic link.
+Done selecting programs.
+
+ +

Selecting default configuration parameters. +The remainder of the work done by configure involves setting up +configuration parameters that control the placement and +setup of files during the installation procedure. + +

    
+Selecting default TIFF configuration parameters.
+
+Looks like manual pages go in /usr/contrib/man.
+Looks like manual pages should be installed with bsd-nroff-gzip-0.gz.
+
+TIFF configuration parameters are:
+
+[ 1] Directory for tools:               /usr/contrib/bin
+[ 2] Directory for libraries:           /usr/contrib/lib
+[ 3] Directory for include files:       /usr/contrib/include
+[ 4] Directory for manual pages:        /usr/contrib/man
+[ 5] Manual page installation scheme:   bsd-nroff-gzip-0.gz
+
+Are these ok [yes]? 
+
+ + + +At this point you can interactively modify any of the +displayed parameters. Hitting a carriage return or typing +yes will accept the current parameters. Typing one +of the number displayed along the left hand side causes +configure to prompt for a new value of the specified parameter. +Typing anything else causes configure to prompt for a new +value for each parameter. +In general hitting carriage return will accept the current +value and typing anything that is unacceptable will cause a +help message to be displayed. +A description of each of the configuration parameters is given below. + +

+Once acceptable parameters are setup configure will generate +all the files that depend on these parameters. Note that certain +files may or may not be created based on the configuration of +optional packages and/or the functions supported by target system. + +

    
+Creating Makefile from ../tiff-v3.4beta015/Makefile.in
+Creating libtiff/Makefile from ../tiff-v3.4beta015/libtiff/Makefile.in
+Creating man/Makefile from ../tiff-v3.4beta015/man/Makefile.in
+Creating tools/Makefile from ../tiff-v3.4beta015/tools/Makefile.in
+Creating port/install.sh from ../tiff-v3.4beta015/port/install.sh.in
+Done.
+
+ +

Shared Library Support

 + +It is desirable to make the TIFF library be a shared object +on systems that have support for shared libraries. +Unfortunately the rules to use to build a shared library +vary between operating systems and even compilers. +The distributed software includes support for building a shared +version of the library on a number of different systems. +This support is split between rules in the file +libtiff/Makefile.in that construct the shared library +and checks done by the configure script to verify that +the expected rules are supported by compilation tools for +the target system. + +

+To add new support for building a shared library both these files +must be updated. +In the configure script search for the section where the autoconfiguration +setting of the DSO parameter is handled and +add a new case for the target system that sets the +DSOSUF, +DSOLD, +DSOOPTS, +and +LIBCOPTS +options as appropriate for the system. +DSOSUF specifies the filename suffix used for the shared +library (e.g. ``.so'' for Dynamic Shared Objects on most SVR4-based +systems). +DSOLD specifies the program to use to build the shared library +from a compiled object file; typically ``${LD}'' though on some systems +it is better to use the C compiler directly so system-dependent options and +libraries are automatically supplied. +DSOOPTS are options that must be specified to DSOLD +when building the shared library. +LIBCOPTS are options to pass to the C compiler when constructing +a relocatable object file to include in a shared library; e.g. ``-K PIC'' +on a Sun system. +The DSO parameter must also be set to a unique label that identifies +the target system and compilation tools. +This label is used to select +a target in libtiff/Makefile.in to do the actual work in building +the shared library. +Finally, to complete support for the shared library added the appropriate +rules to libtiff/Makefile.in under the target specified in the +configure script. + + + + +

Configuration Parameters

+ +This section gives a brief description of the less obvious +configuration parameters. Consult the distributed config.site +for a complete list of parameters. +The list here is sorted alphabetically. + +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
AROPTSThe options passed to ar when creating an archive. +Note that configure will automatically check to see if ar +supports an s to create a symbol table instead of +using ranlib.
DIR_BINThe directory where client applications should be installed; by +default this is /usr/local/bin.
DIR_GZLIBThe pathname of the directory containing the zlib library +(when ZIP or PixarLog compression support is enabled); +e.g. ``../src/zlib''.
DIR_JPEGLIBThe pathname of the directory containing the JPEG library +(when JPEG support is enabled); e.g. ``/usr/local/lib''.
DIR_LIBThe directory to install libraries and DSO's; by default +this is /usr/local/lib.
DIR_MANThe top-most directory of the manual area where manual +pages should be installed.
DIRS_LIBINCA space-separated list of directories in which to search for +include files when building the library and tools. +If JPEG or ZIP support is configured this parameter should include +the directories where the associated include files are located.
DIST_ALPHAThe alpha version number for the distribution; e.g. if this +is version 3.4beta031 then the the major number is 31.
DIST_MAJORThe major version number for the distribution; e.g. if this +is version 3.4beta031 then the the major number is 3.
DIST_MINORThe minor version number for the distribution; e.g. if this +is version 3.4beta031 then the the major number is 4.
DSOSUFWhen DSO's are built, the filename suffix for a DSO. +If this is set to "a" then statically linked archives are used.
DSOSUF_VERSIONWhen DSO's are built, a version-specific filename suffix for a DSO. +If this is set to something other than the value of DSO then +the file libtiff.DSOSUF_VERSION will be installed and +a link to it named libtiff.DSOSUF will automatically +be created. (Note that this means that rule for building the target +DSO must generate a file named libtiff.DSOSUF_VERSION.)
ENVOPTSOptions to pass to CC to force ANSI C compilation.
FILLORDERThe order of bits in a byte on the server machine; +either LSB2MSB or MSB2LSB. +This is normally selected according to the target system.
GCOPTSSpecial options to pass the C compiler. If this parameter +is set, then configure may append other options to this list.
INSTALLThe pathname of the install program to use. Note that this program +must emulate the command line interface used by the IRIX install program.
LIBPORTThe pathname of the library that holds code to emulate missing +system functionality. +Normally this parameter is set by configure based on whether or +not emulation code is required for the target. +
LLDOPTS +Extra command line options passed to CC +when linking an executable. +This option is usually set only when DSO support is enabled +(to force the executable to search for the TIFF DSO +in non-standard locations in the filesystem.)
MACHDEPLIBSTarget-dependent libraries that should be used when linking +tools. +Note that if this parameter is specified configure will append to +the list of libraries.
MANSCHEMEThe scheme to use when preparing and installing manual pages. +Schemes are constructed according to: +
    +<organization>-<formatting>-<compression>[-<suffix>] +
+where: +<organization> is either bsd +for BSD-style section organization (e.g. file formats in +section 5) or sysv for System V-style +organization (e.g. file formats in section 4). +<formatting> is either nroff to force +installation of formatted materials (using nroff) or +source to get the nroff source installed. +<compression> is either the name of a program +to compress the manual pages (gipz, compress, pack) or +cat for uncompressed data. +<suffix> is either the file suffix to convert +installed pages to (e.g. 0.gz for gzip-compressed pages under BSD) +or strip to force the normal ".4f" suffix to be converted to ".4" +(or ".5" if using the BSD organization). If no -<suffix> +is specified then filenames are not converted when they are installed.
PORTFUNCSA list of non-standard functions that should be emulated. +Normally this list is constructed by configure based on checks it does. +If this parameter is set, configure will append to the specified list.
SETMAKEIf make does not automatically set $MAKE to +the name of the make program to invoke for subdirectories, then +configure will create an explicit definition. +If this parameter is set, then it will be used instead. +by default bin is used.
+ + +

Building the Software under Windows 95/98/NT/2000 with MS VC++

+ +With Microsoft Visual C++ installed, and properly configured for commandline +use (you will likely need to source VCVARS32.BAT in AUTOEXEC.bAT or somewhere +similar) you should be able to use the provided makefile.vc.

+ +

+C:\LIBTIFF\LIBTIFF> nmake /f makefile.vc
+C:\LIBTIFF\LIBTIFF> cd ..\tools
+C:\LIBTIFF\TOOLS> nmake /f makefile.vc
+
+ +This will build the library file LIBTIFF\LIBTIFF\LIBTIFF.LIB. This +can be used in Win32 programs. If used in a project using the /MD compiler +switch (using the runtime C library), it may be necessary to modify the +CFLAGS macro in makefile.vc to correspond.

+ +The makefile also builds a DLL (libtiff.dll) with an associated import +library (libtiff_i.lib). Any builds using libtiff will need to include +the LIBTIFF\LIBTIFF directory in the include path.

+ +The libtiff\tools\makefile.vc should build .exe's for all the +standard TIFF tool programs.

+ +NOTE: The contents of the contrib/win32 directory should no longer be +needed, and are kept in the distribution temporarily.

+ +

Building the Software under MS/DOS with the DJGPP v2 compiler

+ +[From the file contrib/dosdjgpp/README.] + +

+The directory contrib/dosdjgpp +contains the files necessary to build the library and tools +with the DJGPP v2 compiler under MSDOS. + +

+All you have to do is copy the files in the directory +into the respective directories and run +make. If you want, you can use the conf.bat script +to do that for you, make sure that +the file is stored with MSDOS text EOL-convention (CR/LF), otherwise the +command.com will not do anything. + +

+Note that you probably will not be able to build the library with the v1.x +versions of djgpp, due to two problems. First, the top makefile calls a +sub-make for each directory and you are likely to run out of memory, since +each recursive invocation of a djgpp v1.x program requires about 130k, to +avoid that, you can enter the directories manually and call make (well, there +are only two dirs). The 2nd problem is that djgpp 1.x doesn't call the +coff2exe (stubify) program when creating an executable. This means that all +programs compiled are not converted to exe and consequently are not available +for calling directly. For the tools directory, you can just call coff2exe for +each program after make finishes, but in the libtiff directory, a few programs +are created during the make process that have to be called for make to +continue (e.g. mkg3states). Make will probably report an error at each +such stage. To fix that, either add a coff2exe call before each program is +called or call coff2exe manually and rerun make (there 2-3 such programs). + + +

Building the Software on a Macintosh with MPW

+ +The directory contrib/mac-mpw contains support for +compiling the library and tools under the MPW Shell on a +Macintosh system. +This support was contributed by Niles Ritter +(ndr@tazboy.jpl.nasa.gov). + +

+[From the file contrib/mac-mpw/README.] + +

+This directory contains all of the utilities and makefile source +to build the LIBTIFF library and tools from the MPW Shell. The +file BUILD.mpw in this directory is an executable script +which uses all of these files to create the MPW makefiles and +run them. + +

+The .make files are not MPW makefiles as such, +but are when run through the "mactrans" program, which turns +the ascii "%nn" metacharacters into the standard weird MPW +make characters. + +

+This translation trick is necessary to protect the files when +they are put into unix tarfiles, which tend to mangle the +special characters. + + + +

Building the Software on a Macintosh with CodeWarrior

+ +The directory contrib/mac-cw contains support for +compiling the library and tools with MetroWerks CodeWarrior 6.1 +on a Macintosh system. +This support was contributed by Niles Ritter +(ndr@tazboy.jpl.nasa.gov). + +

+[From the file contrib/mac-cw/README.] + +In this directory you will find a Makefile.script Applescript +file, which should be run in order to build the libtiff code +using MetroWerks CodeWarrior. + +Refer to the "metrowerks.note" instructions on building the +library for 68k and PowerPC native code, as well as building +some of the libtiff tools, which are rather unix-like, but +at least give an example of how to link everything together. + + + +

Building the Software on a VMS System

+ +The VMS port was done by Karsten Spang +(krs@kampsax.dk), who also +"sort of" maintains it. +The VMS specific files are not in the main directories. Instead they +are placed under [.CONTRIB.VMS...] in the distribution tree. + +Installation: + +It is assumed that you have unpacked the tar file into a VMS directory +tree, in this text called DISK:[TIFF]. + +
    +
  1. Move the VMS specific files to their proper directories. +
    +$ SET DEFAULT DISK:[TIFF.CONTRIB.VMS]
+$ RENAME [.LIBTIFF]*.* [-.-.LIBTIFF]
+$ RENAME [.TOOLS]*.* [-.-.TOOLS]
+
    +
  2. Compile the library. +
    +$ SET DEFAULT DISK:[TIFF.LIBTIFF]
+$ @MAKEVMS
+
    +
  3. Compile the tools. +
    +$ SET DEFAULT DISK:[TIFF.TOOLS]
+$ @MAKEVMS
+
    +
  4. Define the programs. +
    +$ DEFINE TIFFSHR DISK:[TIFF.LIBTIFF]TIFFSHR
+$ FAX2PS    :==$DISK:[TIFF.TOOLS]FAX2PS
+$ FAX2TIFF  :==$DISK:[TIFF.TOOLS]FAX2TIFF
+$ GIF2TIFF  :==$DISK:[TIFF.TOOLS]GIF2TIFF
+$ PAL2RGB   :==$DISK:[TIFF.TOOLS]PAL2RGB
+$ PPM2TIFF  :==$DISK:[TIFF.TOOLS]PPM2TIFF
+$ RAS2TIFF  :==$DISK:[TIFF.TOOLS]RAS2TIFF
+$ RGB2YCBCR :==$DISK:[TIFF.TOOLS]RGB2YCBCR
+$ THUMBNAIL :==$DISK:[TIFF.TOOLS]THUMBNAIL
+$ TIFF2BW   :==$DISK:[TIFF.TOOLS]TIFF2BW
+$ TIFF2PS   :==$DISK:[TIFF.TOOLS]TIFF2PS
+$ TIFFCMP   :==$DISK:[TIFF.TOOLS]TIFFCMP
+$ TIFFCP    :==$DISK:[TIFF.TOOLS]TIFFCP
+$ TIFFDITHER:==$DISK:[TIFF.TOOLS]TIFFDITHER
+$ TIFFDUMP  :==$DISK:[TIFF.TOOLS]TIFFDUMP
+$ TIFFINFO  :==$DISK:[TIFF.TOOLS]TIFFINFO
+$ TIFFMEDIAN:==$DISK:[TIFF.TOOLS]TIFFMEDIAN
+$ TIFFSPLIT :==$DISK:[TIFF.TOOLS]TIFFSPLIT
+$ YCBCR     :==$DISK:[TIFF.TOOLS]YCBCR
+
    +
+ +You will want to add these lines to your LOGIN.COM +file, after changing +the name of the directory that you have used on your machine. + +

+This release has been tested on OpenVMS/VAX 5.5-2, using VAX C 3.2. +A previous release was tested under OpenVMS/AXP ?.? using DEC C ?.?, it is +believed that this release as well works on AXP. +The code contains some GNU C specific things. This does *not* imply, +however, that the VAX/GCC configuration has been tested, *it has not*. + +

+The command procedures (MAKEVMS.COM) for building the +library and tools, +is believed to choose the correct options for the VAX and AXP cases +automatically. + +

+On the AXP, IEEE floating point is used by default. If you want VAX +floating point, remove the /FLOAT=IEEE_FLOAT qualifier, and change +HAVE_IEEEFP=1 to HAVE_IEEEFP=0 in the MAKEVMS.COM +files in both the libtiff and tools directories. + + +

Compiling your own program on a VMS system:

+ +When compiling a source file in which you +"#include ", use the +following command +
+    $ CC/INCLUDE=DISK:[TIFF.LIBTIFF]
+
+This ensures that the header file is found. +On the AXP, also add /FLOAT=IEEE_FLOAT +(if used when building the library). + + +

Linking your own program to the TIFF library on a VMS system:

+ +You can link to the library in two ways: Either using the shareable +library, or using the object library. +On the VAX these possibilities are: + +
    +
  1. Using the shareable TIFF library. +
    +$ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/OPTIONS,SYS$INPUT:/OPTIONS
+    SYS$SHARE:VAXCRTL/SHAREABLE
+
    +
  2. Using the TIFF object library. +
    +$ LINK MY_PROGRAM, -
+    DISK:[TIFF.LIBTIFF]TIFF/LIBRARY/INCLUDE=(TIF_FAX3SM,TIF_CODEC), -
+    SYS$INPUT:/OPTIONS
+    SYS$SHARE:VAXCRTL/SHAREABLE
+
    +
+ +On AXP (and possibly also using DEC C on VAX) the corresponding commands are +
    +
  1. Using the shareable TIFF library. +
    +$ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/OPTIONS
+
    +
  2. Using the TIFF object library. +
    +$ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/LIBRARY
+
    +
+ +Method 1 uses the shortest link time and smallest .EXE +files, but it +requires that TIFFSHR is defined as above at link time and +at run time. +Using the compilation procedure above, the tools are linked in this way. + +

+Method 2 gives somewhat longer link time and larger .EXE +files, but does +not require TIFFSHR to be defined. This method is recommended if you +want to run your program on another machine, and for some reason don't +want to have the library on that machine. If you plan to have more than +one program (including the tools) on the machine, it is recommended that +you copy the library to the other machine and use method 1. + + + +

Building the Software on an Acorn RISC OS system

+ +The directory contrib/acorn contains support for compiling the library +under Acorn C/C++ under Acorn's RISC OS 3.10 or above. Subsequent pathnames +will use the Acorn format: The full-stop or period character is a pathname +delimeter, and the slash character is not interpreted; the reverse position +from Unix. Thus "libtiff/tif_acorn.c" becomes "libtiff.tif_acorn/c". + +

+This support was contributed by Peter Greenham. (peter@enlarion.demon.co.uk). + +

+

Installing LibTIFF:

+ +

+LIBTIFF uses several files which have names longer than the normal RISC OS +maximum of ten characters. This complicates matters. Maybe one day Acorn will +address the problem and implement long filenames properly. Until then this +gets messy, especially as I'm trying to do this with obeyfiles and not have +to include binaries in this distribution. + +

+First of all, ensure you have Truncate configured on (type *Configure +Truncate On) + +

+Although it is, of course, preferable to have long filenames, LIBTIFF can be +installed with short filenames, and it will compile and link without +problems. However, getting it there is more problematic. +contrib.acorn.install is an installation obeyfile which will create a normal +Acorn-style library from the source (ie: with c, h and o folders etc.), but +needs the distribution library to have been unpacked into a location which is +capable of supporting long filenames, even if only temporarily. + +

+My recommendation, until Acorn address this problem properly, is to use Jason +Tribbeck's LongFilenames, or any other +working system that gives you long filenames, like a nearby NFS server for +instance. + +

+If you are using Longfilenames, even if only temporarily to install LIBTIFF, +unpack the TAR into a RAMDisc which has been longfilenamed (ie: *addlongfs +ram) and then install from there to the hard disk. Unfortunately +Longfilenames seems a bit unhappy about copying a bunch of long-named files +across the same filing system, but is happy going between systems. You'll +need to create a ramdisk of about 2Mb. + +

+Now you can run the installation script I've supplied (in contrib.acorn), +which will automate the process of installing LIBTIFF as an Acorn-style +library. The syntax is as follows: + +

+install <source_dir> <dest_dir> + +

+Install will then create <dest_dir> and put the library in there. For +example, having used LongFilenames on the RAMDisk and unpacked the library +into there, you can then type: + +

+Obey RAM::RamDisc0.$.contrib.acorn.install RAM::RamDisc0.$ ADFS::4.$.LIBTIFF +

+ +It doesn't matter if the destination location can cope with long filenames or +not. The filenames will be truncated if necessary (*Configure Truncate On if +you get errors) and all will be well. + +

+

Compiling LibTIFF:

+ +

+Once the LibTIFF folder has been created and the files put inside, making the +library should be just a matter of running 'SetVars' to set the +appropriate system variables, then running 'Makefile'. + +

+OSLib + +

+OSLib +is a comprehensive API for RISC OS machines, written by Jonathan Coxhead of +Acorn Computers (although OSLib is not an official Acorn product). Using the +OSLib SWI veneers produces code which is more compact and more efficient than +code written using _kernel_swi or _swi. The Acorn port of LibTIFF can take +advantage of this if present. Edit the Makefile and go to the Static +dependencies section. The first entry is: + +

+# Static dependencies:
+@.o.tif_acorn:   @.c.tif_acorn
+	cc $(ccflags) -o @.o.tif_acorn @.c.tif_acorn 
+
+

+Change the cc line to: +

+	cc $(ccflags) -DINCLUDE_OSLIB -o @.o.tif_acorn @.c.tif_acorn 
+
+

+Remember, however, that OSLib is only recommended for efficiency's +sake. It is not required. + + + +

Building the Software on Other Systems

+ +This section contains information that might be useful +if you are working on a non-UNIX system that is not directly supported. +All library-related files described below are located in the libtiff +directory. + +

+The library requires two files that are generated on-the-fly. +The file tif_fax3sm.c has the state tables for the +Group 3 and Group 4 decoders. +This file is generated by the mkg3states program +on a UNIX system; for example, + +

    
+cd libtiff
+cc -o mkg3states mkg3states.c
+rm -f tif_fax3sm.c
+./mkg3states -c const tif_fax3sm.c
+
+ +The -c option can be used to control whether or not the +resutling tables are generated with a const declaration. +The -s option can be used to specify a C storage class +for the table declarations. +The -b option can be used to force data values to be +explicitly bracketed with ``{}'' (apparently needed for some +MS-Windows compilers); otherwise the structures are emitted in +as compact a format as possible. +Consult the source code for this program if you have questions. + +

+The second file required to build the library, version.h, +contains the version +information returned by the TIFFGetVersion routine. +This file is built on most systems using the +mkversion program and the contents of the +VERSION and tiff.alpha files; for example, + +

    +cd libtiff
+cc -o mkversion mkversion.c
+rm -f version.h
+./mkversion -v ../VERSION -a ../dist/tiff.alpha version.h
+
+ +

+Otherwise, when building the library on a non-UNIX system be sure to +consult the files tiffcomp.h and tiffconf.h. +The former contains system compatibility definitions while the latter +is provided so that the software configuration can be controlled +on systems that do not support the make facility for building +the software. + +

+Systems without a 32-bit compiler may not be able to handle some +of the codecs in the library; especially the Group 3 and 4 decoder. +If you encounter problems try disabling support for a particular +codec; consult the documentation. + +

+Programs in the tools directory are written to assume an ANSI C +compilation environment. +There may be a few POSIX'isms as well. +The code in the port directory is provided to emulate routines +that may be missing on some systems. +On UNIX systems the configure script automatically figures +out which routines are not present on a system and enables the use +of the equivalent emulation routines from the port directory. +It may be necessary to manually do this work on a non-UNIX system. + + +

Checking out the Software

+ +

+Assuming you have working versions of tiffgt and tiffsv, +you can just +use them to view any of the sample images available for testing +(see the section on obtaining the test images). +Otherwise, you can do a cursory check of the library with +the tiffcp and tiffcmp programs. For example, + +

    +tiffcp -lzw cramps.tif x.tif
+tiffcmp cramps.tif x.tif
+
+ +

+(tiffcmp should be silent if the files compare correctly). + + + +

+This software provides support for the Tag Image File Format (TIFF), +a widely used format for storing image data. The latest version of +the TIFF specification is available on-line +in several different formats, +as are a number of Technical Notes (TTN's). + +

+Included in this software distribution is a library, libtiff, for +reading and writing TIFF, a small collection of tools for doing simple +manipulations of TIFF images on UNIX systems, +and documentation on the library and +tools. A small assortment of TIFF-related software for UNIX +that has been contributed by others is also included. + +

+The library, along with associated tool programs, should handle most of +your needs for reading and writing TIFF images on 32- and 64-bit +machines. This software can also be used on older 16-bit systems +though it may require some effort and you may need to leave out some of +the compression support. + +

The software was orginally authored and maintained by Sam Leffler. +While he keeps a fatherly eye on the mailing list, he is no longer +responsible for day to day maintenance. + +

Questions should be sent to +the TIFF mailing list: tiff@olympiakos.com. + +

The persons responsible for putting up this site and putting together versions >= 3.5.1 are +Frank Warmerdam and Mike Welles. + +

+ +Modifying The TIFF Library +

+ + +

+This chapter provides information about the internal structure of +the library, how to control the configuration when building it, and +how to add new support to the library. +The following sections are found in this chapter: + +

+ + +

Library Configuration

 + +Information on compiling the library is given +elsewhere in this documentation. +This section describes the low-level mechanisms used to control +the optional parts of the library that are configured at build +time. Control is based on +a collection of C defines that are specified either on the compiler +command line or in a configuration file such as port.h +(as generated by the configure script for UNIX systems) +or tiffconf.h. + +

+Configuration defines are split into three areas: +

    +
  • those that control which compression schemes are + configured as part of the builtin codecs, +
  • those that control support for groups of tags that + are considered optional, and +
  • those that control operating system or machine-specific support. +
+ +

+If the define COMPRESSION_SUPPORT is not defined +then a default set of compression schemes is automatically +configured: +

    +
  • CCITT Group 3 and 4 algorithms (compression codes 2, 3, 4, and 32771), +
  • the Macintosh PackBits algorithm (compression 32773), +
  • a Lempel-Ziv & Welch (LZW) algorithm (compression 5), +
  • a 4-bit run-length encoding scheme from ThunderScan (compression 32809), +
  • a 2-bit encoding scheme used by NeXT (compression 32766), and +
  • two experimental schemes intended for images with high dynamic range +(compression 34676 and 34677). +
+ +To override this behaviour define COMPRESSION_SUPPORT +and then one or more additional defines to enable configuration of +the appropriate codecs (see the table below); e.g. + +
    +#define	COMPRESSION_SUPPORT
+#define	CCITT_SUPPORT
+#define	PACKBITS_SUPPORT
+
+ +Several other compression schemes are configured separately from +the default set because they depend on ancillary software +packages that are not distributed with libtiff. + +

+Support for JPEG compression is controlled by JPEG_SUPPORT. +The JPEG codec that comes with libtiff is designed for +use with release 5 or later of the Independent JPEG Group's freely +available software distribution. +This software can be retrieved from the directory +ftp.uu.net:/graphics/jpeg/. + + +

+NOTE: +Enabling JPEG support automatically enables support for +the TIFF 6.0 colorimetry and YCbCr-related tags. + +

+Experimental support for the deflate algorithm is controlled by +DEFLATE_SUPPORT. +The deflate codec that comes with libtiff is designed +for use with version 0.99 or later of the freely available +libz library written by Jean-loup Gailly and Mark Adler. +The data format used by this library is described +in the files +zlib-3.1.doc, +and +deflate-1.1.doc, +available in the directory +ftp.uu.net:/pub/archiving/zip/doc. +The library can be retried from the directory +ftp.uu.net:/pub/archiving/zip/zlib/ +(or try quest.jpl.nasa.gov:/beta/zlib/). + +

+NOTE: +The deflate algorithm is experimental. Do not expect +to exchange files using this compression scheme; +it is included only because the similar, and more common, +LZW algorithm is claimed to be governed by licensing restrictions. + + +

+By default tiffconf.h defines +COLORIMETRY_SUPPORT, +YCBCR_SUPPORT, +and +CMYK_SUPPORT. + +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

General Portability Comments

+ +This software is developed on Silicon Graphics UNIX +systems (big-endian, MIPS CPU, 32-bit ints, +IEEE floating point). +The configure shell script generates the appropriate +include files and make files for UNIX systems. +Makefiles exist for non-UNIX platforms that the +code runs on -- this work has mostly been done by other people. + +

+In general, the code is guaranteed to work only on SGI machines. +In practice it is highly portable to any 32-bit or 64-bit system and much +work has been done to insure portability to 16-bit systems. +If you encounter portability problems please return fixes so +that future distributions can be improved. + +

+The software is written to assume an ANSI C compilation environment. +If your compiler does not support ANSI function prototypes, const, +and <stdarg.h> then you will have to make modifications to the +software. In the past I have tried to support compilers without const +and systems without <stdarg.h>, but I am +no longer interested in these +antiquated environments. With the general availability of +the freely available GCC compiler, I +see no reason to incorporate modifications to the software for these +purposes. + +

+An effort has been made to isolate as many of the +operating system-dependencies +as possible in two files: tiffcomp.h and +libtiff/tif_<os>.c. The latter file contains +operating system-specific routines to do I/O and I/O-related operations. +The UNIX (tif_unix.c), +Macintosh (tif_apple.c), +and VMS (tif_vms.c) +code has had the most use; +the MS/DOS support (tif_msdos.c) assumes +some level of UNIX system call emulation (i.e. +open, +read, +write, +fstat, +malloc, +free). + +

+Native CPU byte order is determined on the fly by +the library and does not need to be specified. +The HOST_FILLORDER and HOST_BIGENDIAN +definitions are not currently used, but may be employed by +codecs for optimization purposes. + +

+The following defines control general portability: + +

+ + + + + + + + + + + + + + + + + + + + + + + + + + +
BSDTYPESDefine this if your system does NOT define the + usual BSD typedefs: u_char, + u_short, u_int, u_long.
HAVE_IEEEFPDefine this as 0 or 1 according to the floating point + format suported by the machine. If your machine does + not support IEEE floating point then you will need to + add support to tif_machdep.c to convert between the + native format and IEEE format.
HAVE_MMAPDefine this if there is mmap-style support for +mapping files into memory (used only to read data).
HOST_FILLORDERDefine the native CPU bit order: one of FILLORDER_MSB2LSB + or FILLORDER_LSB2MSB
HOST_BIGENDIANDefine the native CPU byte order: 1 if big-endian (Motorola) + or 0 if little-endian (Intel); this may be used + in codecs to optimize code
+ +

+On UNIX systems HAVE_MMAP is defined through the running of +the configure script; otherwise support for memory-mapped +files is disabled. +Note that tiffcomp.h defines HAVE_IEEEFP to be +1 (BSDTYPES is not defined). + + +

Types and Portability

+ +The software makes extensive use of C typedefs to promote portability. +Two sets of typedefs are used, one for communication with clients +of the library and one for internal data structures and parsing of the +TIFF format. There are interactions between these two to be careful +of, but for the most part you should be able to deal with portability +purely by fiddling with the following machine-dependent typedefs: + + +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
uint88-bit unsigned integertiff.h
int88-bit signed integertiff.h
uint1616-bit unsigned integertiff.h
int1616-bit signed integertiff.h
uint3232-bit unsigned integertiff.h
int3232-bit signed integertiff.h
dblparam_tpromoted type for floatstiffcomp.h
+ +

+(to clarify dblparam_t, it is the type that float parameters are +promoted to when passed by value in a function call.) + +

+The following typedefs are used throughout the library and interfaces +to refer to certain objects whose size is dependent on the TIFF image +structure: + + +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
typedef unsigned int ttag_t; directory tag
typedef uint16 tdir_t; directory index
typedef uint16 tsample_t; sample number
typedef uint32 tstrip_t; strip number
typedef uint32 ttile_t; tile number
typedef int32 tsize_t; i/o size in bytes
typedef void* tdata_t; image data ref
typedef void* thandle_t; client data handle
typedef int32 toff_t; file offset (should be off_t)
typedef unsigned char* tidata_t; internal image data
+ +

+Note that tstrip_t, ttile_t, and tsize_t +are constrained to be +no more than 32-bit quantities by 32-bit fields they are stored +in in the TIFF image. Likewise tsample_t is limited by the 16-bit +field used to store the SamplesPerPixel tag. tdir_t +constrains +the maximum number of IFDs that may appear in an image and may +be an arbitrary size (without penalty). ttag_t must be either +int, unsigned int, pointer, or double +because the library uses a varargs +interface and ANSI C restricts the type of the parameter before an +ellipsis to be a promoted type. toff_t is defined as +int32 because +TIFF file offsets are (unsigned) 32-bit quantities. A signed +value is used because some interfaces return -1 on error (sigh). +Finally, note that tidata_t is used internally to the library to +manipulate internal data. User-specified data references are +passed as opaque handles and only cast at the lowest layers where +their type is presumed. + + +

General Comments

+ +The library is designed to hide as much of the details of TIFF from +applications as +possible. In particular, TIFF directories are read in their entirety +into an internal format. Only the tags known by the library are +available to a user and certain tag data may be maintained that a user +does not care about (e.g. transfer function tables). + +

Adding New Tags

 + +To add support for a new directory tag you have three options. If your +tag is specific to a compression algorithm, see below. If you have a lot +of tags you may want to try using Niles Ritter's runtime tag-extension +scheme in the "contrib/tags" directory, which makes the changes +orthogonal to the main libtiff code. Otherwise use +the following guidelines to add support to the ``core library''. + +
    +
  1. Define the tag in tiff.h. +
  2. Add a field to the directory structure in tif_dir.h + and define a FIELD_* bit (also update the definition of + FIELD_CODEC to reflect your addition). +
  3. Add an entry in the TIFFFieldInfo array defined at the top of + tif_dirinfo.c. + Note that you must keep this array sorted by tag + number and that the widest variant entry for a tag should come + first (e.g. LONG before SHORT). +
  4. Add entries in _TIFFVSetField() and _TIFFVGetField() + for the new tag. +
  5. (optional) If the value associated with the tag is not a scalar value + (e.g. the array for TransferFunction) and requires + special processing, + then add the appropriate code to TIFFReadDirectory() and + TIFFWriteDirectory(). You're best off finding a similar tag and + cribbing code. +
  6. Add support to TIFFPrintDirectory() in tif_print.c + to print the tag's value. +
+ +

+If you want to maintain portability, beware of making assumptions +about data types. Use the typedefs (uint16, etc. when dealing with +data on disk and t*_t when stuff is in memory) and be careful about +passing items through printf or similar vararg interfaces. + +

Adding New Builtin Codecs

+ +To add builtin support for a new compression algorithm, you can either +use the "tag-extension" trick to override the handling of the +TIFF Compression tag (see Adding New Tags, above), +or do the following to add support directly to the core library: + +
    +
  1. Define the tag value in tiff.h. +
  2. Edit the file tif_codec.c to add an entry to the + _TIFFBuiltinCODECS array (see how other algorithms are handled). +
  3. Add the appropriate function prototype declaration to + tiffiop.h (close to the bottom). +
  4. Create a file with the compression scheme code, by convention files + are named tif_*.c (except perhaps on some systems where the + tif_ prefix pushes some filenames over 14 chars. +
  5. Edit Makefile.in (and any other Makefiles) + to include the new source file. +
+ +

+A codec, say foo, can have many different entry points: + +

+TIFFInitfoo(tif, scheme)/* initialize scheme and setup entry points in tif */
+fooSetupDecode(tif)	/* called once per IFD after tags has been frozen */
+fooPreDecode(tif, sample)/* called once per strip/tile, after data is read,
+			    but before the first row is decoded */
+fooDecode*(tif, bp, cc, sample)/* decode cc bytes of data into the buffer */
+    fooDecodeRow(...)	/* called to decode a single scanline */
+    fooDecodeStrip(...)	/* called to decode an entire strip */
+    fooDecodeTile(...)	/* called to decode an entire tile */
+fooSetupEncode(tif)	/* called once per IFD after tags has been frozen */
+fooPreEncode(tif, sample)/* called once per strip/tile, before the first row in
+			    a strip/tile is encoded */
+fooEncode*(tif, bp, cc, sample)/* encode cc bytes of user data (bp) */
+    fooEncodeRow(...)	/* called to decode a single scanline */
+    fooEncodeStrip(...)	/* called to decode an entire strip */
+    fooEncodeTile(...)	/* called to decode an entire tile */
+fooPostEncode(tif)	/* called once per strip/tile, just before data is written */
+fooSeek(tif, row)	/* seek forwards row scanlines from the beginning
+			   of a strip (row will always be >0 and <rows/strip */
+fooCleanup(tif)		/* called when compression scheme is replaced by user */
+
+ +

+Note that the encoding and decoding variants are only needed when +a compression algorithm is dependent on the structure of the data. +For example, Group 3 2D encoding and decoding maintains a reference +scanline. The sample parameter identifies which sample is to be +encoded or decoded if the image is organized with PlanarConfig=2 +(separate planes). This is important for algorithms such as JPEG. +If PlanarConfig=1 (interleaved), then sample will always be 0. + + +

Adding New Codec-private Tags

+ +To add tags that are meaningful only when a particular compression +algorithm is used follow these steps: + +
    +
  1. Define the tag in tiff.h. +
  2. Allocate storage for the tag values in the private state block of + the codec. +
  3. Insure the state block is created when the codec is initialized. +
  4. At TIFFInitfoo time override the method pointers in the + TIFF structure + for getting, setting and printing tag values. For example, +
    +    sp->vgetparent = tif->tif_vgetfield;
+    tif->tif_vgetfield = fooVGetField;	/* hook for codec tags */
+    sp->vsetparent = tif->tif_vsetfield;
+    tif->tif_vsetfield = fooVSetField;	/* hook for codec tags */
+    tif->tif_printdir = fooPrintDir;	/* hook for codec tags */
+
    + (Actually you may decide not to override the + tif_printdir method, but rather just specify it). +
  5. Create a private TIFFFieldInfo array for your tags and + merge them into the core tags at initialization time using + _TIFFMergeFieldInfo; e.g. +
    +    _TIFFMergeFieldInfo(tif, fooFieldInfo, N(fooFieldInfo));
+
    + (where N is a macro used liberaly throughout the distributed code). +
  6. Fill in the get and set routines. Be sure to call the parent method + for tags that you are not handled directly. Also be sure to set the + FIELD_* bits for tags that are to be written to the file. Note that + you can create ``pseudo-tags'' by defining tags that are processed + exclusively in the get/set routines and never written to file (see + the handling of TIFFTAG_FAXMODE in tif_fax3.c + for an example of this). +
  7. Fill in the print routine, if appropriate. +
+ +Note that space has been allocated in the FIELD_* bit space for +codec-private tags. Define your bits as FIELD_CODEC+<offset> to +keep them away from the core tags. If you need more tags than there +is room for, just increase FIELD_SETLONGS at the top of +tiffiop.h. + + +

Other Comments

 + +The library handles most I/O buffering. There are two data buffers +when decoding data: a raw data buffer that holds all the data in a +strip, and a user-supplied scanline buffer that compression schemes +place decoded data into. When encoding data the data in the +user-supplied scanline buffer is encoded into the raw data buffer (from +where it is written). Decoding routines should never have to explicitly +read data -- a full strip/tile's worth of raw data is read and scanlines +never cross strip boundaries. Encoding routines must be cognizant of +the raw data buffer size and call TIFFFlushData1() when necessary. +Note that any pending data is automatically flushed when a new strip/tile is +started, so there's no need do that in the tif_postencode routine (if +one exists). Bit order is automatically handled by the library when +a raw strip or tile is filled. If the decoded samples are interpreted +by the decoding routine before they are passed back to the user, then +the decoding logic must handle byte-swapping by overriding the +tif_postdecode +routine (set it to TIFFNoPostDecode) and doing the required work +internally. For an example of doing this look at the horizontal +differencing code in the routines in tif_predict.c. + +

+The variables tif_rawcc, tif_rawdata, and +tif_rawcp in a TIFF structure +are associated with the raw data buffer. tif_rawcc must be non-zero +for the library to automatically flush data. The variable +tif_scanlinesize is the size a user's scanline buffer should be. The +variable tif_tilesize is the size of a tile for tiled images. This +should not normally be used by compression routines, except where it +relates to the compression algorithm. That is, the cc parameter to the +tif_decode* and tif_encode* +routines should be used in terminating +decompression/compression. This ensures these routines can be used, +for example, to decode/encode entire strips of data. + +

+In general, if you have a new compression algorithm to add, work from +the code for an existing routine. In particular, +tif_dumpmode.c +has the trivial code for the "nil" compression scheme, +tif_packbits.c is a +simple byte-oriented scheme that has to watch out for buffer +boundaries, and tif_lzw.c has the LZW scheme that has the most +complexity -- it tracks the buffer boundary at a bit level. +Of course, using a private compression scheme (or private tags) limits +the portability of your TIFF files. + +

+ +Introduction to the TIFF Documentation +

+ + +

+The following definitions are used throughout this documentation. +They are consistent with the terminology used in the TIFF 6.0 specification. + +

+
Sample +
The unit of information stored in an image; often called a + channel elsewhere. Sample values are numbers, usually unsigned + integers, but possibly in some other format if the SampleFormat + tag is specified in a TIFF +
Pixel +
A collection of one or more samples that go together. +
Row +
An Nx1 rectangular collection of pixels. +
Tile +
An NxM rectangular organization of data (or pixels). +
Strip +
A tile whose width is the full image width. +
Compression +
A scheme by which pixel or sample data are stored in + an encoded form, specifically with the intent of reducing the + storage cost. +
Codec +
Software that implements the decoding and encoding algorithms + of a compression scheme. + + +

+In order to better understand how TIFF works (and consequently this +software) it is important to recognize the distinction between the +physical organization of image data as it is stored in a TIFF and how +the data is interpreted and manipulated as pixels in an image. TIFF +supports a wide variety of storage and data compression schemes that +can be used to optimize retrieval time and/or minimize storage space. +These on-disk formats are independent of the image characteristics; it +is the responsibility of the TIFF reader to process the on-disk storage +into an in-memory format suitable for an application. Furthermore, it +is the responsibility of the application to properly interpret the +visual characteristics of the image data. TIFF defines a framework for +specifying the on-disk storage format and image characteristics with +few restrictions. This permits significant complexity that can be +daunting. Good applications that handle TIFF work by handling as wide +a range of storage formats as possible, while constraining the +acceptable image characteristics to those that make sense for the +application. + + +

+ +Using The TIFF Library +

+ +

+libtiff is a set of C functions (a library) that support +the manipulation of TIFF image files. +The library requires an ANSI C compilation environment for building +and presumes an ANSI C environment for use. + +

+libtiff +provides interfaces to image data at several layers of abstraction (and cost). +At the highest level image data can be read into an 8-bit/sample, +ABGR pixel raster format without regard for the underlying data organization, +colorspace, or compression scheme. Below this high-level interface +the library provides scanline-, strip-, and tile-oriented interfaces that +return data decompressed but otherwise untransformed. These interfaces +require that the application first identify the organization of stored +data and select either a strip-based or tile-based API for manipulating +data. At the lowest level the library +provides access to the raw uncompressed strips or tiles, +returning the data exactly as it appears in the file. + +

+The material presented in this chapter is a basic introduction +to the capabilities of the library; it is not an attempt to describe +everything a developer needs to know about the library or about TIFF. +Detailed information on the interfaces to the library are given in +the +UNIX manual pages that accompany this software. + +

+The following sections are found in this chapter: + +

+ + +

How to tell which version you have

 + +The software version can be found by looking at the file named +VERSION +that is located at the top of the source tree; the precise alpha number +is given in the file dist/tiff.alpha. +If you have need to refer to this +specific software, you should identify it as: + +
+    TIFF <version> <alpha>
+
+ +where <version> is whatever you get from +"cat VERSION" and <alpha> is +what you get from "cat dist/tiff.alpha". + +

+Within an application that uses libtiff the TIFFGetVersion +routine will return a pointer to a string that contains software version +information. +The library include file <tiffio.h> contains a C pre-processor +define TIFFLIB_VERSION that can be used to check library +version compatiblity at compile time. + +

Library Datatypes

+ +libtiff defines a portable programming interface through the +use of a set of C type definitions. +These definitions, defined in in the files tiff.h and +tiffio.h, +isolate the libtiff API from the characteristics +of the underlying machine. +To insure portable code and correct operation, applications that use +libtiff should use the typedefs and follow the function +prototypes for the library API. + +

Memory Management

 + +libtiff uses a machine-specific set of routines for managing +dynamically allocated memory. +_TIFFmalloc, _TIFFrealloc, and _TIFFfree +mimic the normal ANSI C routines. +Any dynamically allocated memory that is to be passed into the library +should be allocated using these interfaces in order to insure pointer +compatibility on machines with a segmented architecture. +(On 32-bit UNIX systems these routines just call the normal malloc, +realloc, and free routines in the C library.) + +

+To deal with segmented pointer issues libtiff also provides +_TIFFmemcpy, _TIFFmemset, and _TIFFmemmove +routines that mimic the equivalent ANSI C routines, but that are +intended for use with memory allocated through _TIFFmalloc +and _TIFFrealloc. + +

Error Handling

+ +libtiff handles most errors by returning an invalid/erroneous +value when returning from a function call. +Various diagnostic messages may also be generated by the library. +All error messages are directed to a single global error handler +routine that can be specified with a call to TIFFSetErrorHandler. +Likewise warning messages are directed to a single handler routine +that can be specified with a call to TIFFSetWarningHandler + +

Basic File Handling

 + +The library is modeled after the normal UNIX stdio library. +For example, to read from an existing TIFF image the +file must first be opened: + +
    +#include "tiffio.h" +main() +{ + TIFF* tif = TIFFOpen("foo.tif", "r"); + ... do stuff ... + TIFFClose(tif); +} +
+ +The handle returned by TIFFOpen is opaque, that is +the application is not permitted to know about its contents. +All subsequent library calls for this file must pass the handle +as an argument. + +

+To create or overwrite a TIFF image the file is also opened, but with +a "w" argument: + +

    +#include "tiffio.h" +main() +{ + TIFF* tif = TIFFOpen("foo.tif", "w"); + ... do stuff ... + TIFFClose(tif); +} +
+ +If the file already exists it is first truncated to zero length. + +

+ +Note that unlike the stdio library TIFF image files may not be +opened for both reading and writing; +there is no support for altering the contents of a TIFF file. + + +

+libtiff buffers much information associated with writing a +valid TIFF image. Consequently, when writing a TIFF image it is necessary +to always call TIFFClose or TIFFFlush to flush any +buffered information to a file. Note that if you call TIFFClose +you do not need to call TIFFFlush. + +

TIFF Directories

+ +TIFF supports the storage of multiple images in a single file. +Each image has an associated data structure termed a directory +that houses all the information about the format and content of the +image data. +Images in a file are usually related but they do not need to be; it +is perfectly alright to store a color image together with a black and +white image. +Note however that while images may be related their directories are +not. +That is, each directory stands on its own; their is no need to read +an unrelated directory in order to properly interpret the contents +of an image. + +

+libtiff provides several routines for reading and writing +directories. In normal use there is no need to explicitly +read or write a directory: the library automatically reads the first +directory in a file when opened for reading, and directory information +to be written is automatically accumulated and written when writing +(assuming TIFFClose or TIFFFlush are called). + +

+For a file open for reading the TIFFSetDirectory routine can +be used to select an arbitrary directory; directories are referenced by +number with the numbering starting at 0. Otherwise the +TIFFReadDirectory and TIFFWriteDirectory routines can +be used for sequential access to directories. +For example, to count the number of directories in a file the following +code might be used: + +

    +#include "tiffio.h" +main(int argc, char* argv[]) +{ + TIFF* tif = TIFFOpen(argv[1], "r"); + if (tif) { + int dircount = 0; + do { + dircount++; + } while (TIFFReadDirectory(tif)); + printf("%d directories in %s\n", dircount, argv[1]); + TIFFClose(tif); + } + exit(0); +} +
+ +

+Finally, note that there are several routines for querying the +directory status of an open file: +TIFFCurrentDirectory returns the index of the current +directory and +TIFFLastDirectory returns an indication of whether the +current directory is the last directory in a file. +There is also a routine, TIFFPrintDirectory, that can +be called to print a formatted description of the contents of +the current directory; consult the manual page for complete details. + +

TIFF Tags

+ +Image-related information such as the image width and height, number +of samples, orientation, colorimetric information, etc. +are stored in each image +directory in fields or tags. +Tags are identified by a number that is usually a value registered +with the Aldus (now Adobe) Corporation. +Beware however that some vendors write +TIFF images with tags that are unregistered; in this case interpreting +their contents is usually a waste of time. + +

+libtiff reads the contents of a directory all at once +and converts the on-disk information to an appropriate in-memory +form. While the TIFF specification permits an arbitrary set of +tags to be defined and used in a file, the library only understands +a limited set of tags. +Any unknown tags that are encountered in a file are ignored. +There is a mechanism to extend the set of tags the library handles +without modifying the library itself; +this is described elsewhere. + +

+libtiff provides two interfaces for getting and setting tag +values: TIFFGetField and TIFFSetField. +These routines use a variable argument list-style interface to pass +parameters of different type through a single function interface. +The get interface takes one or more pointers to memory locations +where the tag values are to be returned and also returns one or +zero according to whether the requested tag is defined in the directory. +The set interface takes the tag values either by-reference or +by-value. +The TIFF specification defines +default values for some tags. +To get the value of a tag, or its default value if it is undefined, +the TIFFGetFieldDefaulted interface may be used. + +

+The manual pages for the tag get and set routines specifiy the exact data types +and calling conventions required for each tag supported by the library. + +

TIFF Compression Schemes

+ +libtiff includes support for a wide variety of +data compression schemes. +In normal operation a compression scheme is automatically used when +the TIFF Compression tag is set, either by opening a file +for reading, or by setting the tag when writing. + +

+Compression schemes are implemented by software modules termed codecs +that implement decoder and encoder routines that hook into the +core library i/o support. +Codecs other than those bundled with the library can be registered +for use with the TIFFRegisterCODEC routine. +This interface can also be used to override the core-library +implementation for a compression scheme. + +

Byte Order

+ +The TIFF specification says, and has always said, that +a correct TIFF +reader must handle images in big-endian and little-endian byte order. +libtiff conforms in this respect. +Consequently there is no means to force a specific +byte order for the data written to a TIFF image file (data is +written in the native order of the host CPU unless appending to +an existing file, in which case it is written in the byte order +specified in the file). + + +

Data Placement

 + +The TIFF specification requires that all information except an +8-byte header can be placed anywhere in a file. +In particular, it is perfectly legitimate for directory information +to be written after the image data itself. +Consequently TIFF is inherently not suitable for passing through a +stream-oriented mechanism such as UNIX pipes. +Software that require that data be organized in a file in a particular +order (e.g. directory information before image data) does not +correctly support TIFF. +libtiff provides no mechanism for controlling the placement +of data in a file; image data is typically written before directory +information. + +

TIFFRGBAImage Support

 + +libtiff provides a high-level interface for reading image +data from a TIFF file. This interface handles the details of +data organization and format for a wide variety of TIFF files; +at least the large majority of those files that one would normally +encounter. Image data is, by default, returned as ABGR +pixels packed into 32-bit words (8 bits per sample). Rectangular +rasters can be read or data can be intercepted at an intermediate +level and packed into memory in a format more suitable to the +application. +The library handles all the details of the format of data stored on +disk and, in most cases, if any colorspace conversions are required: +bilevel to RGB, greyscale to RGB, CMYK to RGB, YCbCr to RGB, 16-bit +samples to 8-bit samples, associated/unassociated alpha, etc. + +

+There are two ways to read image data using this interface. If +all the data is to be stored in memory and manipulated at once, +then the routine TIFFReadRGBAImage can be used: + +

    +#include "tiffio.h" +main(int argc, char* argv[]) +{ + TIFF* tif = TIFFOpen(argv[1], "r"); + if (tif) { + uint32 w, h; + size_t npixels; + uint32* raster; + + TIFFGetField(tif, TIFFTAG_IMAGEWIDTH, &w); + TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &h); + npixels = w * h; + raster = (uint32*) _TIFFmalloc(npixels * sizeof (uint32)); + if (raster != NULL) { + if (TIFFReadRGBAImage(tif, w, h, raster, 0)) { + ...process raster data... + } + _TIFFfree(raster); + } + TIFFClose(tif); + } + exit(0); +} +
+ +Note above that _TIFFmalloc is used to allocate memory for +the raster passed to TIFFReadRGBAImage; this is important +to insure the ``appropriate type of memory'' is passed on machines +with segmented architectures. + +

+Alternatively, TIFFReadRGBAImage can be replaced with a +more low-level interface that permits an application to have more +control over this reading procedure. The equivalent to the above +is: + +

    +#include "tiffio.h" +main(int argc, char* argv[]) +{ + TIFF* tif = TIFFOpen(argv[1], "r"); + if (tif) { + TIFFRGBAImage img; + char emsg[1024]; + + if (TIFFRGBAImageBegin(&img, tif, 0, emsg)) { + size_t npixels; + uint32* raster; + + npixels = img.width * img.height; + raster = (uint32*) _TIFFmalloc(npixels * sizeof (uint32)); + if (raster != NULL) { + if (TIFFRGBAImageGet(&img, raster, img.width, img.width)) { + ...process raster data... + } + _TIFFfree(raster); + } + TIFFRGBAImageEnd(&img); + } else + TIFFError(argv[1], emsg); + TIFFClose(tif); + } + exit(0); +} +
+ +However this usage does not take advantage of the more fine-grained +control that's possible. That is, by using this interface it is +possible to: + +
    +
  • repeatedly fetch (and manipulate) an image without opening + and closing the file +
  • interpose a method for packing raster pixel data according to + application-specific needs (or write the data at all) +
  • interpose methods that handle TIFF formats that are not already + handled by the core library +
+ +The first item means that, for example, image viewers that want to +handle multiple files can cache decoding information in order to +speedup the work required to display a TIFF image. + +

+The second item is the main reason for this interface. By interposing +a ``put method'' (the routine that is called to pack pixel data in +the raster) it is possible share the core logic that understands how +to deal with TIFF while packing the resultant pixels in a format that +is optimized for the application. This alternate format might be very +different than the 8-bit per sample ABGR format the library writes by +default. For example, if the application is going to display the image +on an 8-bit colormap display the put routine might take the data and +convert it on-the-fly to the best colormap indices for display. + +

+The last item permits an application to extend the library +without modifying the core code. +By overriding the code provided an application might add support +for some esoteric flavor of TIFF that it needs, or it might +substitute a packing routine that is able to do optimizations +using application/environment-specific information. + +

+The TIFF image viewer found in tools/sgigt.c is an example +of an application that makes use of the TIFFRGBAImage +support. + +

Scanline-based Image I/O

+ +The simplest interface provided by libtiff is a +scanline-oriented interface that can be used to read TIFF +images that have their image data organized in strips +(trying to use this interface to read data written in tiles +will produce errors.) +A scanline is a one pixel high row of image data whose width +is the width of the image. +Data is returned packed if the image data is stored with samples +packed together, or as arrays of separate samples if the data +is stored with samples separated. +The major limitation of the scanline-oriented interface, other +than the need to first identify an existing file as having a +suitable organization, is that random access to individual +scanlines can only be provided when data is not stored in a +compressed format, or when the number of rows in a strip +of image data is set to one (RowsPerStrip is one). + +

+Two routines are provided for scanline-based i/o: +TIFFReadScanline +and +TIFFWriteScanline. +For example, to read the contents of a file that +is assumed to be organized in strips, the following might be used: + +

    +#include "tiffio.h" +main() +{ + TIFF* tif = TIFFOpen("myfile.tif", "r"); + if (tif) { + uint32 imagelength; + tdata_t buf; + uint32 row; + + TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &imagelength); + buf = _TIFFmalloc(TIFFScanlineSize(tif)); + for (row = 0; row < imagelength; row++) + TIFFReadScanline(tif, buf, row); + _TIFFfree(buf); + TIFFClose(tif); + } +} +
+ +TIFFScanlineSize returns the number of bytes in +a decoded scanline, as returned by TIFFReadScanline. +Note however that if the file had been create with samples +written in separate planes, then the above code would only +read data that contained the first sample of each pixel; +to handle either case one might use the following instead: + +
    +#include "tiffio.h" +main() +{ + TIFF* tif = TIFFOpen("myfile.tif", "r"); + if (tif) { + uint32 imagelength; + tdata_t buf; + uint32 row; + + TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &imagelength); + TIFFGetField(tif, TIFFTAG_PLANARCONFIG, &config); + buf = _TIFFmalloc(TIFFScanlineSize(tif)); + if (config == PLANARCONFIG_CONTIG) { + for (row = 0; row < imagelength; row++) + TIFFReadScanline(tif, buf, row); + } else if (config == PLANARCONFIG_SEPARATE) { + uint16 s, nsamples; + + TIFFGetField(tif, TIFFTAG_SAMPLESPERPIXEL, &nsamples); + for (s = 0; s < nsamples; s++) + for (row = 0; row < imagelength; row++) + TIFFReadScanline(tif, buf, row, s); + } + _TIFFfree(buf); + TIFFClose(tif); + } +} +
+ +Beware however that if the following code were used instead to +read data in the case PLANARCONFIG_SEPARATE, + +
    + for (row = 0; row < imagelength; row++) + for (s = 0; s < nsamples; s++) + TIFFReadScanline(tif, buf, row, s); +
+ +then problems would arise if RowsPerStrip was not one +because the order in which scanlines are requested would require +random access to data within strips (something that is not supported +by the library when strips are compressed). + +

Strip-oriented Image I/O

 + +The strip-oriented interfaces provided by the library provide +access to entire strips of data. Unlike the scanline-oriented +calls, data can be read or written compressed or uncompressed. +Accessing data at a strip (or tile) level is often desirable +because there are no complications with regard to random access +to data within strips. + +

+A simple example of reading an image by strips is: + +

    +#include "tiffio.h" +main() +{ + TIFF* tif = TIFFOpen("myfile.tif", "r"); + if (tif) { + tdata_t buf; + tstrip_t strip; + + buf = _TIFFmalloc(TIFFStripSize(tif)); + for (strip = 0; strip < TIFFNumberOfStrips(tif); strip++) + TIFFReadEncodedStrip(tif, strip, buf, (tsize_t) -1); + _TIFFfree(buf); + TIFFClose(tif); + } +} +
+ +Notice how a strip size of -1 is used; TIFFReadEncodedStrip +will calculate the appropriate size in this case. + +

+The above code reads strips in the order in which the +data is physically stored in the file. If multiple samples +are present and data is stored with PLANARCONFIG_SEPARATE +then all the strips of data holding the first sample will be +read, followed by strips for the second sample, etc. + +

+Finally, note that the last strip of data in an image may have fewer +rows in it than specified by the RowsPerStrip tag. A +reader should not assume that each decoded strip contains a full +set of rows in it. + +

+The following is an example of how to read raw strips of data from +a file: + +

    +#include "tiffio.h" +main() +{ + TIFF* tif = TIFFOpen("myfile.tif", "r"); + if (tif) { + tdata_t buf; + tstrip_t strip; + uint32* bc; + uint32 stripsize; + + TIFFGetField(tif, TIFFTAG_STRIPBYTECOUNTS, &bc); + stripsize = bc[0]; + buf = _TIFFmalloc(stripsize); + for (strip = 0; strip < TIFFNumberOfStrips(tif); strip++) { + if (bc[strip] > stripsize) { + buf = _TIFFrealloc(buf, bc[strip]); + stripsize = bc[strip]; + } + TIFFReadRawStrip(tif, strip, buf, bc[strip]); + } + _TIFFfree(buf); + TIFFClose(tif); + } +} +
+ +As above the strips are read in the order in which they are +physically stored in the file; this may be different from the +logical ordering expected by an application. + +

Tile-oriented Image I/O

 + +Tiles of data may be read and written in a manner similar to strips. +With this interface, an image is +broken up into a set of rectangular areas that may have dimensions +less than the image width and height. All the tiles +in an image have the same size, and the tile width and length must each +be a multiple of 16 pixels. Tiles are ordered left-to-right and +top-to-bottom in an image. As for scanlines, samples can be packed +contiguously or separately. When separated, all the tiles for a sample +are colocated in the file. That is, all the tiles for sample 0 appear +before the tiles for sample 1, etc. + +

+Tiles and strips may also be extended in a z dimension to form +volumes. Data volumes are organized as "slices". That is, all the +data for a slice is colocated. Volumes whose data is organized in +tiles can also have a tile depth so that data can be organized in +cubes. + +

+There are actually two interfaces for tiles. +One interface is similar to scanlines, to read a tiled image, +code of the following sort might be used: + +

    +main() +{ + TIFF* tif = TIFFOpen("myfile.tif", "r"); + if (tif) { + uint32 imageWidth, imageLength; + uint32 tileWidth, tileLength; + uint32 x, y; + tdata_t buf; + + TIFFGetField(tif, TIFFTAG_IMAGEWIDTH, &imageWidth); + TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &imageLength); + TIFFGetField(tif, TIFFTAG_TILEWIDTH, &tileWidth); + TIFFGetField(tif, TIFFTAG_TILELENGTH, &tileLength); + buf = _TIFFmalloc(TIFFTileSize(tif)); + for (y = 0; y < imageLength; y += tileLength) + for (x = 0; x < imageWidth; x += tileWidth) + TIFFReadTile(tif, buf, x, y, 0); + _TIFFfree(buf); + TIFFClose(tif); + } +} +
+ +(once again, we assume samples are packed contiguously.) + +

+Alternatively a direct interface to the low-level data is provided +a la strips. Tiles can be read with +TIFFReadEncodedTile or +TIFFReadRawTile, +and written with +TIFFWriteEncodedTile or +TIFFWriteRawTile. +For example, to read all the tiles in an image: + +

    +#include "tiffio.h" +main() +{ + TIFF* tif = TIFFOpen("myfile.tif", "r"); + if (tif) { + tdata_t buf; + ttile_t tile; + + buf = _TIFFmalloc(TIFFTileSize(tif)); + for (tile = 0; tile < TIFFNumberOfTiles(tif); tile++) + TIFFReadEncodedTile(tif, tile, buf, (tsize_t) -1); + _TIFFfree(buf); + TIFFClose(tif); + } +} +
+ + + +

NAME

+ +TIFFError, TIFFSetErrorHandler - library error handling interface +  +

SYNOPSIS

+ +#include <tiffio.h> + +
+ +void TIFFError(const char* module, const char* fmt, ...) + +

+#include <stdarg.h> + +
+ +typedef void (*TIFFErrorHandler)(const char* module, const char* fmt, va_list ap); + +
+ +TIFFErrorHandler TIFFSetErrorHandler(TIFFErrorHandler handler); + +  +

DESCRIPTION

+ +TIFFError + +invokes the library-wide error handling function +to (normally) write an error message to the +stderr. + +The +fmt + +parameter is a +printf(3S) + +format string, and any number arguments can be supplied. +The +module + +parameter, if non-zero, is printed before the message; it typically +is used to identify the software module in which an error +is detected. +

+ +Applications that desire to capture control in the event of an error +should use +TIFFSetErrorHandler + +to override the default error handler. +A +NULL +(0) error handling function may be installed to +suppress error messages. +  +

RETURN VALUES

+ +TIFFSetErrorHandler + +returns a reference to the previous error handling function. +  +

NAME

+ +TIFFGetField, TIFFVGetField - get the value(s) of a tag in an open +TIFF +file +  +

SYNOPSIS

+ +#include <tiffio.h> + +
+ +int TIFFGetField(TIFF* tif, ttag_t tag, ...) + +

+#include <stdarg.h> + +
+ +int TIFFVGetField(TIFF* tif, ttag_t tag, va_list ap) + +

+int TIFFGetFieldDefaulted(TIFF* tif, ttag_t tag, ...) + +
+ +int TIFFVGetFieldDefaulted(TIFF* tif, ttag_t tag, va_list ap) + +  +

DESCRIPTION

+ +TIFFGetField + +returns the value of a tag or pseudo-tag associated with the +the current directory of the open +TIFF +file +tif. + +(A +pseudo-tag + +is a parameter that is used to control the operation of the +TIFF +library but whose value is not read or written to the underlying file.) +The file must have been previously opened with +TIFFOpen(3T). + +The tag is identified by +tag, + +one of the values defined in the include file +tiff.h + +(see also the table below). +The type and number of values returned is dependent +on the tag being requested. +The programming interface uses a variable argument list +as prescribed by the +stdarg(3) + +interface. +The returned values should only be interpreted if +TIFFGetField + +returns 1. +

+ +TIFFVGetField + +is functionally equivalent to +TIFFGetField + +except that it takes a pointer to a variable +argument list. +TIFFVGetField + +is useful for layering interfaces on top of +the functionality provided by +TIFFGetField. + +

+ +TIFFGetFieldDefaulted + +and +TIFFVGetFieldDefaulted + +are identical to +TIFFGetField + +and +TIFFVGetField, + +except that if a tag is not defined in the current directory +and it has a default value, then the default value is returned. +

+ +The tags understood by +libtiff, + +the number of parameter values, and the +types for the returned values are shown below. +The data types are specified as in C and correspond +to the types used to specify tag values to +TIFFSetField(3T). + +Remember that +TIFFGetField + +returns parameter values, so all the listed +data types are pointers to storage where values +should be returned. +Consult the +TIFF +specification for information on the meaning of +each tag and their possible values. +

NAME

SYNOPSIS

+ +
+#include <tiffio.h>
+TIFF* TIFFOpen(const char* filename, const char* mode)
+
+TIFF* TIFFFdOpen(const int fd, const char* filename, const char* mode)
+
+typedef tsize_t (*TIFFReadWriteProc)(thandle_t, tdata_t, tsize_t);
+typedef toff_t (*TIFFSeekProc)(thandle_t, toff_t, int);
+typedef int (*TIFFCloseProc)(thandle_t);
+typedef toff_t (*TIFFSizeProc)(thandle_t);
+typedef int (*TIFFMapFileProc)(thandle_t, tdata_t*, toff_t*);
+typedef void (*TIFFUnmapFileProc)(thandle_t, tdata_t, toff_t);
+
+TIFF* TIFFClientOpen(const char* filename, const char* mode, thandle_t clientdata,
+    TIFFReadWriteProc readproc, TIFFReadWriteProc writeproc, TIFFSeekProc seekproc,
+    TIFFCloseProc closeproc, TIFFSizeProc sizeproc, TIFFMapFileProc mapproc,
+    TIFFUnmapFileProc unmapproc)
+
+ +  +

DESCRIPTION

+ +TIFFOpen + +opens a +TIFF +file whose name is +filename + +and returns a handle to be used in subsequent calls to routines in +libtiff. + +If the open operation fails, then zero is returned. +The +mode + +parameter specifies if the file is to be opened for reading (``r''), +writing (``w''), or appending (``a'') and, optionally, whether +to override certain default aspects of library operation (see below). +When a file is opened for appending, existing data will not +be touched; instead new data will be written as additional subfiles. +If an existing file is opened for writing, all previous data is +overwritten. +

+ +If a file is opened for reading, the first +TIFF +directory in the file is automatically read +(also see +TIFFSetDirectory(3T) + +for reading directories other than the first). +If a file is opened for writing or appending, a default directory +is automatically created for writing subsequent data. +This directory has all the default values specified in +TIFF +Revision 6.0: +BitsPerSample=1, + +ThreshHolding=bilevel art scan, + +FillOrder=1 + +(most significant bit of each data byte is filled first), +Orientation=1 + +(the 0th row represents the visual top of the image, and the 0th +column represents the visual left hand side), +SamplesPerPixel=1, + +RowsPerStrip=infinity, + +ResolutionUnit=2 + +(inches), and +Compression=1 + +(no compression). +To alter these values, or to define values for additional fields, +TIFFSetField(3T) + +must be used. +

+ +TIFFFdOpen + +is like +TIFFOpen + +except that it opens a +TIFF +file given an open file descriptor +fd. + +The file's name and mode must reflect that of the open descriptor. +The object associated with the file descriptor +must support random access. + +

+ +TIFFClientOpen + +is like +TIFFOpen + +except that the caller supplies a collection of functions that the +library will use to do UNIX-like I/O operations. +The +readproc + +and +writeproc + +are called to read and write data at the current file position. +seekproc + +is called to change the current file position a la +lseek(2). + +closeproc + +is invoked to release any resources associated with an open file. +sizeproc + +is invoked to obtain the size in bytes of a file. +mapproc + +and +unmapproc + +are called to map and unmap a file's contents in memory; c.f. +mmap(2) + +and +munmap(2). + +The +clientdata + +parameter is an opaque ``handle'' passed to the client-specified +routines passed as parameters to +TIFFClientOpen. + +  +

OPTIONS

+ +The open mode parameter can include the following flags in +addition to the ``r'', ``w'', and ``a'' flags. +Note however that option flags must follow the read-write-append +specification. +
+
l + +
+When creating a new file force information be written with +Little-Endian byte order (but see below). +By default the library will create new files using the native +CPU +byte order. +
b + +
+When creating a new file force information be written with +Big-Endian byte order (but see below). +By default the library will create new files using the native +CPU +byte order. +
L + +
+Force image data that is read or written to be treated with +bits filled from Least Significant Bit (LSB) to +Most Significant Bit (MSB). +Note that this is the opposite to the way the library has +worked from its inception. +
B + +
+Force image data that is read or written to be treated with +bits filled from Most Significant Bit (MSB) to +Least Significant Bit (LSB); this is the default. +
H + +
+Force image data that is read or written to be treated with +bits filled in the same order as the native +CPU. +
M + +
+Enable the use of memory-mapped files for images opened read-only. +If the underlying system does not support memory-mapped files +or if the specific image being opened cannot be memory-mapped +then the library will fallback to using the normal system interface +for reading information. +By default the library will attempt to use memory-mapped files. +
m + +
+Disable the use of memory-mapped files. +
C + +
+Enable the use of ``strip chopping'' when reading images +that are comprised of a single strip or tile of uncompressed data. +Strip chopping is a mechanism by which the library will automatically +convert the single-strip image to multiple strips, +each of which has about 8 Kilobytes of data. +This facility can be useful in reducing the amount of memory used +to read an image because the library normally reads each strip +in its entirety. +Strip chopping does however alter the apparent contents of the +image because when an image is divided into multiple strips it +looks as though the underlying file contains multiple separate +strips. +Finally, note that default handling of strip chopping is a compile-time +configuration parameter. +The default behaviour, for backwards compatibility, is to enable +strip chopping. +
c + +
+Disable the use of strip chopping when reading images. +
+  +

BYTE ORDER

+ +The +TIFF +specification (all versions) states that compliant readers +must be capable of reading images written in either byte order. + +Nonetheless some software that claims to support the reading of +TIFF +images is incapable of reading images in anything but the native +CPU +byte order on which the software was written. +(Especially notorious +are applications written to run on Intel-based machines.) +By default the library will create new files with the native +byte-order of the +CPU +on which the application is run. +This ensures optimal performance and is portable to any application +that conforms to the TIFF specification. +To force the library to use a specific byte-order when creating +a new file the ``b'' and ``l'' option flags may be included in +the call to open a file; for example, ``wb'' or ``wl''. +  +

RETURN VALUES

+ +Upon successful completion +TIFFOpen, + +TIFFFdOpen, + +and +TIFFClientOpen + +return a +TIFF +pointer. +Otherwise, NULL is returned. +  +

DIAGNOSTICS

+ +All error messages are directed to the +TIFFError(3T) + +routine. +Likewise, warning messages are directed to the +TIFFWarning(3T) + +routine. +

+ +"%s": Bad mode. +The specified +mode + +parameter was not one of ``r'' (read), ``w'' (write), or ``a'' (append). +

+ +%s: Cannot open. + +TIFFOpen() + +was unable to open the specified filename for read/writing. +

+ +Cannot read TIFF header. + +An error occurred while attempting to read the header information. +

+ +Error writing TIFF header. + +An error occurred while writing the default header information +for a new file. +

+ +Not a TIFF file, bad magic number %d (0x%x). + +The magic number in the header was not (hex) +0x4d4d or (hex) 0x4949. +

+ +Not a TIFF file, bad version number %d (0x%x). + +The version field in the header was not 42 (decimal). +

+ +Cannot append to file that has opposite byte ordering. + +A file with a byte ordering opposite to the native byte +ordering of the current machine was opened for appending (``a''). +This is a limitation of the library. +  +

+ +The routines described here provide a high-level interface +through which +TIFF +images may be read into memory. +Images may be strip- or tile-based and have a variety of different +characteristics: bits/sample, samples/pixel, photometric, etc. +Decoding state is encapsulated in a +TIFFRGBAImage + +structure making it possible to capture state for multiple images +and quickly switch between them. +The target raster format can be customized to a particular application's +needs by installing custom routines that manipulate image data +according to application requirements. +

+ +The default usage for these routines is: check if an image can +be processed using +TIFFRGBAImageOK, + +construct a decoder state block using +TIFFRGBAImageBegin, + +read and decode an image into a target raster using +TIFFRGBAImageGet, + +and then +release resources using +TIFFRGBAImageEnd. + +TIFFRGBAImageGet + +can be called multiple times to decode an image using different +state parameters. +If multiple images are to be displayed and there is not enough +space for each of the decoded rasters, multiple state blocks can +be managed and then calls can be made to +TIFFRGBAImageGet + +as needed to display an image. +

+ +The generated raster is assumed to be an array of +width + +times +height + +32-bit entries, where +width + +must be less than or equal to the width of the image (height + +may be any non-zero size). +If the raster dimensions are smaller than the image, the image data +is cropped to the raster bounds. +If the raster height is greater than that of the image, then the +image data are placed in the lower part of the raster. +(Note that the raster is assume to be organized such that the pixel +at location (x,y) is raster[y*width+x]; +with the raster origin in the lower-left hand corner.) +

+ +Raster pixels are 8-bit packed red, green, blue, alpha samples. +The macros +TIFFGetR, + +TIFFGetG, + +TIFFGetB, + +and +TIFFGetA + +should be used to access individual samples. +Images without Associated Alpha matting information have a constant +Alpha of 1.0 (255). +

+ +TIFFRGBAImageGet + +converts non-8-bit images by scaling sample values. +Palette, grayscale, bilevel, +CMYK, and YCbCr images are converted to +RGB +transparently. +Raster pixels are returned uncorrected by any colorimetry information +present in the directory. +

+ +The paramater +stopOnError + +specifies how to act if an error is encountered while reading +the image. +If +stopOnError + +is non-zero, then an error will terminate the operation; otherwise +TIFFRGBAImageGet + +will continue processing data until all the possible data in the +image have been requested. +  +

ALTERNATE RASTER FORMATS

+ +To use the core support for reading and processing +TIFF +images, but write the resulting raster data in a different format +one need only override the ``put methods'' used to store raster data. +These methods are are defined in the +TIFFRGBAImage + +structure and initially setup by +TIFFRGBAImageBegin + +to point to routines that pack raster data in the default +ABGR +pixel format. +Two different routines are used according to the physical organization +of the image data in the file: +PlanarConfiguration=1 + +(packed samples), +and +PlanarConfiguration=2 + +(separated samples). +Note that this mechanism can be used to transform the data before +storing it in the raster. +For example one can convert data +to colormap indices for display on a colormap display. +  +

SIMULTANEOUS RASTER STORE AND DISPLAY

+ +It is simple to display an image as it is being read into memory +by overriding the put methods as described above for supporting +alternate raster formats. +Simply keep a reference to the default put methods setup by +TIFFRGBAImageBegin + +and then invoke them before or after each display operation. +For example, the +tiffgt(1) + +utility uses the following put method to update the display as +the raster is being filled: +

+

+static void
+putContigAndDraw(TIFFRGBAImage* img, uint32* raster,
+    uint32 x, uint32 y, uint32 w, uint32 h,
+    int32 fromskew, int32 toskew,
+    unsigned char* cp)
+{
+    (*putContig)(img, raster, x, y, w, h, fromskew, toskew, cp);
+    if (x+w == width) {
+        w = width;
+        if (img->orientation == ORIENTATION_TOPLEFT)
+            lrectwrite(0, y-(h-1), w-1, y, raster-x-(h-1)*w);
+        else
+            lrectwrite(0, y, w-1, y+h-1, raster);
+    }
+}
+
+ +

+(the original routine provided by the library is saved in the +variable +putContig.) + +  +

SUPPORTING ADDITIONAL TIFF FORMATS

+ +The +TIFFRGBAImage + +routines support the most commonly encountered flavors of +TIFF. +It is possible to extend this support by overriding the ``get method'' +invoked by +TIFFRGBAImageGet + +to read +TIFF +image data. +Details of doing this are a bit involved, it is best to make a copy +of an existing get method and modify it to suit the needs of an +application. +  +

NOTES

+ +Samples must be either 1, 2, 4, 8, or 16 bits. +Colorimetric samples/pixel must be either 1, 3, or 4 (i.e. +SamplesPerPixel + +minus +ExtraSamples). + +

+ +Palettte image colormaps that appear to be incorrectly written +as 8-bit values are automatically scaled to 16-bits. +  +

RETURN VALUES

+ +All routines return +1 if the operation was successful. +Otherwise, 0 is returned if an error was encountered and +stopOnError + +is zero. +  +

DIAGNOSTICS

+ +All error messages are directed to the +TIFFError(3T) + +routine. +

+ +Sorry, can not handle %d-bit pictures. + +The image had +BitsPerSample + +other than 1, 2, 4, 8, or 16. +

+ +Sorry, can not handle %d-channel images. + +The image had +SamplesPerPixel + +other than 1, 3, or 4. +

+ +Missing needed "PhotometricInterpretation" tag. +The image did not have a tag that describes how to display +the data. +

+ +No "PhotometricInterpretation" tag, assuming RGB. +The image was missing a tag that describes how to display it, +but because it has 3 or 4 samples/pixel, it is assumed to be +RGB. +

+ +No "PhotometricInterpretation" tag, assuming min-is-black. +The image was missing a tag that describes how to display it, +but because it has 1 sample/pixel, it is assumed to be a grayscale +or bilevel image. +

+ +No space for photometric conversion table. + +There was insufficient memory for a table used to convert +image samples to 8-bit +RGB. +

+ +Missing required "Colormap" tag. +A Palette image did not have a required +Colormap + +tag. +

+ +No space for tile buffer. + +There was insufficient memory to allocate an i/o buffer. +

+ +No space for strip buffer. + +There was insufficient memory to allocate an i/o buffer. +

+ +Can not handle format. + +The image has a format (combination of +BitsPerSample, + +SamplesPerPixel, + +and +PhotometricInterpretation) + +that can not be handled. +

+ +No space for B&W mapping table. + +There was insufficient memory to allocate a table used to map +grayscale data to +RGB. +

+ +No space for Palette mapping table. + +There was insufficient memory to allocate a table used to map +data to 8-bit +RGB. +  +

NAME

+ +TIFFReadDirectory - get the contents of the next directory in an open +TIFF +file +  +

SYNOPSIS

+ +#include <tiffio.h> + +
+ +int TIFFReadDirectory(TIFF* tif) + +  +

DESCRIPTION

+ +Read the next directory in the specified file and make it the +current directory. +Applications only need to call +TIFFReadDirectory + +to read multiple subfiles in a single +TIFF +file- +the first directory in a file is automatically read when +TIFFOpen + +is called. +  +

NOTES

+ +If the library is compiled with +STRIPCHOP_SUPPORT +enabled, then images that have a single uncompressed strip or +tile of data are automatically treated as if they were made +up of multiple strips or tiles of approximately 8 kilobytes each. +This operation is done only in-memory; it does not alter the +contents of the file. +However, the construction of the ``chopped strips'' is visible +to the application through the number of strips [tiles] +returned by +TIFFNumberOfStrips + +[TIFFNumberOfTiles]. + +  +

RETURN VALUES

+ +If the next directory was successfully read, 1 is returned. +Otherwise, 0 is returned if an error was encountered, +or if there are no more directories to be read. +  +

DIAGNOSTICS

+ +All error messages are directed to the +TIFFError(3T) + +routine. +All warning messages are directed to the +TIFFWarning(3T) + +routine. +

+ +Seek error accessing TIFF directory. +An error occurred while positioning to the location of the +directory. +

+ +Wrong data type %d for field "%s". +The tag entry in the directory had an incorrect data type. +For example, an +ImageDescription + +tag with a +SHORT +data type. +

+ +TIFF directory is missing required "%s" field. +The specified tag is required to be present by the +TIFF +5.0 specification, but is missing. +The directory is (usually) unusable. +

+ +%s: Rational with zero denominator. +A directory tag has a +RATIONAL +value whose denominator is zero. +

+ +Incorrect count %d for field "%s" (%lu, expecting %lu); tag ignored. +The specified tag's count field is bad. +For example, a count other than 1 for a +SubFileType + +tag. +

+ +Cannot handle different per-sample values for field "%s". +The tag has +SamplesPerPixel + +values and they are not all the same; e.g. +BitsPerSample. + +The library is unable to handle images of this sort. +

+ +Count mismatch for field "%s"; expecting %d, got %d. +The count field in a +tag does not agree with the number expected by the library. +This should never happen, so if it does, the library refuses to +read the directory. +

+ +Invalid TIFF directory; tags are not sorted in ascending order. +The directory tags are not properly sorted as specified +in the +TIFF +5.0 specification. +This error is not fatal. +

+ +Ignoring unknown field with tag %d (0x%x). +An unknown tag was encountered in the directory; +the library ignores all such tags. +

+ +TIFF directory is missing requred "ImageLength" field. +The image violates the specification by not having a necessary field. +There is no way for the library to recover from this error. +

+ +TIFF directory is missing requred "PlanarConfig" field. +The image violates the specification by not having a necessary field. +There is no way for the library to recover from this error. +

+ +TIFF directory is missing requred "StripOffsets" field. +The image has multiple strips, but is missing the tag that +specifies the file offset to each strip of data. +There is no way for the library to recover from this error. +

+ +TIFF directory is missing requred "TileOffsets" field. +The image has multiple tiles, but is missing the tag that +specifies the file offset to each tile of data. +There is no way for the library to recover from this error. +

+ +TIFF directory is missing required "StripByteCounts" field. +The image has multiple strips, but is missing the tag that +specifies the size of each strip of data. +There is no way for the library to recover from this error. +

+ +TIFF directory is missing required "StripByteCounts" field, calculating from imagelength. +The image violates the specification by not having a necessary field. +However, when the image is comprised of only one strip or tile, the +library will estimate the missing value based on the file size. +

+ +Bogus "StripByteCounts" field, ignoring and calculating from imagelength. +Certain vendors violate the specification by writing zero for +the StripByteCounts tag when they want to leave the value +unspecified. +If the image has a single strip, the library will estimate +the missing value based on the file size. +  +

NOTES

+ +The value of +strip + +is a ``raw strip number.'' +That is, the caller must take into account whether or not the +data are organized in separate planes (PlanarConfiguration=2). + +To read a full strip of data the data buffer should typically be +at least as large as the number returned by +TIFFStripSize(3T). + +

+ +The library attempts to hide bit- and byte-ordering differences +between the image and the native machine by converting data +to the native machine order. +Bit reversal is done if the +FillOrder + +tag is opposite to the native machine bit order. +16- and 32-bit samples are automatically byte-swapped if the +file was written with a byte order opposite to the native +machine byte order, +  +

RETURN VALUES

NAME

+ +TIFFReadRGBAStrip - read and decode an image strip into a fixed-format raster +  +

SYNOPSIS

+ +
+#include <tiffio.h>
+
+#define TIFFGetR(abgr)      ((abgr) & 0xff)
+#define TIFFGetG(abgr)      (((abgr) >> 8) & 0xff)

+
+int TIFFReadRGBAStrip(TIFF* tif, tstrip_t strip, uint32 * raster )
+
  +

DESCRIPTION

+ +TIFFReadRGBAStrip + +reads a single strip of a strip-based image into memory,
+storing the result in the user supplied RGBA +raster. + +The raster is assumed to be an array of +width times rowsperstrip 32-bit entries, where width +is the width of the image (TIFFTAG_IMAGEWIDTH) and +rowsperstrip is the maximum lines in a strip (TIFFTAG_ROWSPERSTRIP). +

+

+ +The +strip + +value should be the strip number (strip zero is the first) as returned by the +TIFFComputeStrip + +function, but always for sample 0. +

+

+ +Note that the raster is assume to be organized such that the pixel +at location (x,y) is raster[y*width+x]; +with the raster origin in the +lower-left hand corner + +of the strip. That is bottom to top organization. When reading a partial +last strip in the file the last line of the image will begin at the +beginning of the buffer. +

+

+ +Raster pixels are 8-bit packed red, green, blue, alpha samples. +The macros +TIFFGetR, + +TIFFGetG, + +TIFFGetB, + +and +TIFFGetA + +should be used to access individual samples. +Images without Associated Alpha matting information have a constant +Alpha of 1.0 (255). +

+ +See the +TIFFRGBAImage(3T) + +page for more details on how various image types are converted to RGBA +values. +  +

NOTES

+ +Samples must be either 1, 2, 4, 8, or 16 bits. +Colorimetric samples/pixel must be either 1, 3, or 4 (i.e. +SamplesPerPixel + +minus +ExtraSamples). + +

+ +Palette image colormaps that appear to be incorrectly written +as 8-bit values are automatically scaled to 16-bits. +

+ +TIFFReadRGBAStrip + +is just a wrapper around the more general +TIFFRGBAImage(3T) + +facilities. It's main advantage over the similar +TIFFReadRGBAImage() + +function is that for large images a single +buffer capable of holding the whole image doesn't need to be allocated, +only enough for one strip. The +TIFFReadRGBATile() + +function does a similar operation for tiled images. +  +

RETURN VALUES

+ +1 is returned if the image was successfully read and converted. +Otherwise, 0 is returned if an error was encountered. +  +

DIAGNOSTICS

+ +All error messages are directed to the +TIFFError(3T) + +routine. +

+ +Sorry, can not handle %d-bit pictures. + +The image had +BitsPerSample + +other than 1, 2, 4, 8, or 16. +

+ +Sorry, can not handle %d-channel images. + +The image had +SamplesPerPixel + +other than 1, 3, or 4. +

+ +Missing needed "PhotometricInterpretation" tag. +The image did not have a tag that describes how to display +the data. +

+ +No "PhotometricInterpretation" tag, assuming RGB. +The image was missing a tag that describes how to display it, +but because it has 3 or 4 samples/pixel, it is assumed to be +RGB. +

+ +No "PhotometricInterpretation" tag, assuming min-is-black. +The image was missing a tag that describes how to display it, +but because it has 1 sample/pixel, it is assumed to be a grayscale +or bilevel image. +

+ +No space for photometric conversion table. + +There was insufficient memory for a table used to convert +image samples to 8-bit +RGB. +

+ +Missing required "Colormap" tag. +A Palette image did not have a required +Colormap + +tag. +

+ +No space for tile buffer. + +There was insufficient memory to allocate an i/o buffer. +

+ +No space for strip buffer. + +There was insufficient memory to allocate an i/o buffer. +

NAME

+ +TIFFReadRGBATile - read and decode an image tile into a fixed-format raster +  +

SYNOPSIS

+ +
+#include <tiffio.h>
+
+#define TIFFGetR(abgr)      ((abgr) & 0xff)
+#define TIFFGetG(abgr)      (((abgr) >> 8) & 0xff)
+#define TIFFGetB(abgr)      (((abgr) >> 16) & 0xff)
+#define TIFFGetA(abgr)      (((abgr) >> 24) & 0xff)
+
+int TIFFReadRGBATile(TIFF* tif, uint32 x, uint32 y, uint32 * raster )
+
  +

DESCRIPTION

+ +TIFFReadRGBATile + +reads a single tile of a tile-based image into memory,
+storing the result in the user supplied RGBA +raster. + +The raster is assumed to be an array of +width times length 32-bit entries, where width +is the width of a tile (TIFFTAG_TILEWIDTH) and +length is the height of a tile (TIFFTAG_TILELENGTH). +

+

+ +The +x + +and +y + +values are the offsets from the top left corner to the top left corner +of the tile to be read. They must be an exact multiple of the tile +width and length. +

+

+ +Note that the raster is assume to be organized such that the pixel +at location (x,y) is raster[y*width+x]; +with the raster origin in the +lower-left hand corner + +of the tile. That is bottom to top organization. Edge tiles which +partly fall off the image will be filled out with appropriate zeroed +areas. +

+

+ +Raster pixels are 8-bit packed red, green, blue, alpha samples. +The macros +TIFFGetR, + +TIFFGetG, + +TIFFGetB, + +and +TIFFGetA + +should be used to access individual samples. +Images without Associated Alpha matting information have a constant +Alpha of 1.0 (255). +

+ +See the +TIFFRGBAImage(3T) + +page for more details on how various image types are converted to RGBA +values. +  +

NOTES

+ +Samples must be either 1, 2, 4, 8, or 16 bits. +Colorimetric samples/pixel must be either 1, 3, or 4 (i.e. +SamplesPerPixel + +minus +ExtraSamples). + +

+ +Palette image colormaps that appear to be incorrectly written +as 8-bit values are automatically scaled to 16-bits. +

+ +TIFFReadRGBATile + +is just a wrapper around the more general +TIFFRGBAImage(3T) + +facilities. It's main advantage over the similar +TIFFReadRGBAImage() + +function is that for large images a single +buffer capable of holding the whole image doesn't need to be allocated, +only enough for one tile. The +TIFFReadRGBAStrip() + +function does a similar operation for stripped images. +  +

RETURN VALUES

+ +1 is returned if the image was successfully read and converted. +Otherwise, 0 is returned if an error was encountered. +  +

DIAGNOSTICS

+ +All error messages are directed to the +TIFFError(3T) + +routine. +

+ +Sorry, can not handle %d-bit pictures. + +The image had +BitsPerSample + +other than 1, 2, 4, 8, or 16. +

+ +Sorry, can not handle %d-channel images. + +The image had +SamplesPerPixel + +other than 1, 3, or 4. +

+ +Missing needed "PhotometricInterpretation" tag. +The image did not have a tag that describes how to display +the data. +

+ +No "PhotometricInterpretation" tag, assuming RGB. +The image was missing a tag that describes how to display it, +but because it has 3 or 4 samples/pixel, it is assumed to be +RGB. +

+ +No "PhotometricInterpretation" tag, assuming min-is-black. +The image was missing a tag that describes how to display it, +but because it has 1 sample/pixel, it is assumed to be a grayscale +or bilevel image. +

+ +No space for photometric conversion table. + +There was insufficient memory for a table used to convert +image samples to 8-bit +RGB. +

+ +Missing required "Colormap" tag. +A Palette image did not have a required +Colormap + +tag. +

+ +No space for tile buffer. + +There was insufficient memory to allocate an i/o buffer. +

+ +No space for strip buffer. + +There was insufficient memory to allocate an i/o buffer. +

+ +Can not handle format. + +The image has a format (combination of +BitsPerSample, + +SamplesPerPixel, + +and +PhotometricInterpretation) + +that +TIFFReadRGBAImage + +can not handle. +

+ +No space for B&W mapping table. + +There was insufficient memory to allocate a table used to map +grayscale data to +RGB. +

+ +No space for Palette mapping table. + +There was insufficient memory to allocate a table used to map +data to 8-bit +RGB. +  +

NAME

+ +TIFFReadScanline - read and decode a scanline of data from an open +TIFF +file +  +

SYNOPSIS

+ +#include <tiffio.h> + +
+ +int TIFFReadScanline(TIFF* tif, tdata_t buf, uint32 row, tsample_t sample) + +  +

DESCRIPTION

+ +Read the data for the specified row into the (user supplied) +data buffer +buf. + +The data are returned decompressed and, in the native byte- +and bit-ordering, but are otherwise packed (see further below). +The buffer must be large enough to hold an entire scanline of data. +Applications should call the routine +TIFFScanlineSize + +to find out the size (in bytes) of a scanline buffer. +The +row + +parameter is always used by +TIFFReadScanline; + +the +sample + +parameter is used only if data are organized in separate planes (PlanarConfiguration=2). + +  +

NOTES

+ +The library attempts to hide bit- and byte-ordering differences +between the image and the native machine by converting data +to the native machine order. +Bit reversal is done if the +FillOrder + +tag is opposite to the native machine bit order. +16- and 32-bit samples are automatically byte-swapped if the +file was written with a byte order opposite to the native +machine byte order, +

+ +In C++ the +sample + +parameter defaults to 0. +  +

RETURN VALUES

+ +TIFFReadScanline + +returns -1 if it detects an error; otherwise 1 is returned. +  +

DIAGNOSTICS

+ +All error messages are directed to the +TIFFError(3T) + +routine. +

+ +Compression algorithm does not support random access. + +Data was requested in a non-sequential order from a file that +uses a compression algorithm and that has +RowsPerStrip + +greater than one. +That is, data in the image is stored in a compressed form, +and with multiple rows packed into a strip. +In this case, the library does not support random access to the data. +The data should either be accessed sequentially, or the file +should be converted so that each strip is made up of one row +of data. +  +

BUGS

+ +Reading subsampled YCbCR data does not work correctly +because, for +PlanarConfiguration=2 + +the size of a scanline is not calculated on a per-sample basis, +and for +PlanarConfiguration=1 + +the library does not unpack the block-interleaved samples; use +the strip- and tile-based interfaces to read these formats. +  +

NAME

+ +TIFFSetField - set the value(s) of a tag in a +TIFF +file open for writing +  +

SYNOPSIS

+ +#include <tiffio.h> + +
+ +int TIFFSetField(TIFF* tif, ttag_t tag, ...) + +
+ +#include <stdarg.h> + +
+ +int TIFFVSetField(TIFF* tif, ttag_t tag, va_list ap) + +  +

DESCRIPTION

+ +TIFFSetField + +sets the value of a field +or pseudo-tag in the current directory associated with +the open +TIFF +file +tif. + +(A +pseudo-tag + +is a parameter that is used to control the operation of the +TIFF +library but whose value is not read or written to the underlying file.) +To set the value of a field +the file must have been previously opened for writing with +TIFFOpen(3T); + +pseudo-tags can be set whether the file was opened for reading +or writing. +The field is identified by +tag, + +one of the values defined in the include file +tiff.h + +(see also the table below). +The actual value is specified using a variable argument list, +as prescribed by the +stdarg(3) + +interface (or, on some machines, the +varargs(3) + +interface.) +

+ +TIFFVSetField + +is functionally equivalent to +TIFFSetField + +except that it takes a pointer to a variable +argument list. +TIFFVSetField + +is useful for writing routines that are layered +on top of the functionality provided by +TIFFSetField. + +

+ +The tags understood by +libtiff, + +the number of parameter values, and the +expected types for the parameter values are shown below. +The data types are: +char* + +is null-terminated string and corresponds to the +ASCII +data type; +uint16 + +is an unsigned 16-bit value; +uint32 + +is an unsigned 32-bit value; +uint16* + +is an array of unsigned 16-bit values. +void* + +is an array of data values of unspecified type. +

+Consult the +TIFF +specification for information on the meaning of each tag. +

NAME

+ +TIFFWarning, TIFFSetWarningHandler - library warning interface +  +

SYNOPSIS

+ +#include <tiffio.h> + +
+ +void TIFFWarning(const char* module, const char* fmt, ...) + +

+#include <stdargh.h> + +
+ +typedef void (*TIFFWarningHandler)(const char* module, const char* fmt, va_list ap); + +
+ +TIFFWarningHandler TIFFSetWarningHandler(TIFFWarningHandler handler); + +  +

DESCRIPTION

+ +TIFFWarning + +invokes the library-wide warning handler function +to (normally) write a warning message to the +stderr. + +The +fmt + +parameter is a +printf(3S) + +format string, and any number arguments can be supplied. +The +module + +parameter is interpreted as a string that, if non-zero, +should be printed before the message; it typically +is used to identify the software module in which a warning +is detected. +

+ +Applications that desire to capture control in the event of a warning +should use +TIFFSetWarningHandler + +to override the default warning handler. +A +NULL +(0) warning handler function may be installed to +suppress error messages. +  +

RETURN VALUES

+ +TIFFSetWarningHandler + +returns a reference to the previous error handling function. +  +

+ +int TIFFWriteDirectory(TIFF* tif) + +  +

DESCRIPTION

+ +Write the contents of the current directory to the file and setup +to create a new subfile in the same file. +Applications only need to call +TIFFWriteDirectory + +when writing multiple subfiles to a single +TIFF +file. +TIFFWriteDirectory + +is automatically called by +TIFFClose + +and +TIFFFlush + +to write a modified directory if the file is open for writing. +  +

RETURN VALUES

+ +1 is returned when the contents are successfully +written to the file. +Otherwise, 0 is returned if an error was encountered when writing +the directory contents. +  +

DIAGNOSTICS

+ +All error messages are directed to the +TIFFError(3T) + +routine. +

+ +Error post-encoding before directory write. + +Before writing the contents of the current directory, any pending +data are flushed. +This message indicates that an error occurred while doing this. +

+ +Error flushing data before directory write. + +Before writing the contents of the current directory, any pending +data are flushed. +This message indicates that an error occurred while doing this. +

+ +Cannot write directory, out of space. + +There was not enough space to allocate a temporary area for +the directory that was to be written. +

+ +Error writing directory count. + +A write error occurred when writing the count of fields in the directory. +

+ +Error writing directory contents. + +A write error occurred when writing the directory fields. +

+ +Error writing directory link. + +A write error occurred when writing the link to the next directory. +

+ +Error writing data for field "%s". +A write error occurred when writing indirect data for the specified field. +

+ +Error writing TIFF header. + +A write error occurred when re-writing header at the front of the file. +

+ +Error fetching directory count. + +A read error occurred when fetching the directory count field for +a previous directory. +This can occur when setting up a link to the directory that is being +written. +

+ +Error fetching directory link. + +A read error occurred when fetching the directory link field for +a previous directory. +This can occur when setting up a link to the directory that is being +written. +  +

+ +tsize_t TIFFWriteEncodedStrip(TIFF* tif, tstrip_t strip, tdata_t buf, tsize_t size) + +  +

DESCRIPTION

+ +Compress +size + +bytes of raw data from +buf + +and write the result to the specified strip; replacing +any previously written data. +Note that the value of +strip + +is a ``raw strip number.'' +That is, the caller must take into account whether or not the +data are organized in separate places (PlanarConfiguration=2). + +  +

NOTES

+ +The library writes encoded data using the native machine byte order. +Correctly implemented +TIFF +readers are expected to do any necessary byte-swapping to +correctly process image data with BitsPerSample greater than 8. +

+ +The strip number must be valid according to the current settings +of the +ImageLength + +and +RowsPerStrip + +tags. +An image may be dynamically grown by increasing the value of +ImageLength + +prior to each call to +TIFFWriteEncodedStrip. + +  +

RETURN VALUES

+ +-1 is returned if an error was encountered. +Otherwise, the value of +size + +is returned. +  +

DIAGNOSTICS

NAME

+ +TIFFWriteScanline - write a scanline to an open +TIFF +file +  +

SYNOPSIS

+ +#include <tiffio.h> + +
+ +int TIFFWriteScanline(TIFF* tif, tdata_t buf, uint32 row, tsample_t sample) + +  +

DESCRIPTION

+ +Write data to a file at the specified row. +The +sample + +parameter is used only if data are organized in separate planes (PlanarConfiguration=2). + +The data are assumed to be uncompressed and in the native +bit- and byte-order of the host machine. +The data written to the file is +compressed according to the compression scheme +of the current +TIFF +directory (see further below). +If the current scanline is past the end of the current subfile, the +ImageLength + +field is automatically increased to include the scanline (except +for +PlanarConfiguration=2, + +where the +ImageLength + +cannot be changed once the first data are written). +If the +ImageLength + +is increased, the +StripOffsets + +and +StripByteCounts + +fields are similarly enlarged to reflect data written past the +previous end of image. +  +

NOTES

+ +The library writes encoded data using the native machine byte order. +Correctly implemented +TIFF +readers are expected to do any necessary byte-swapping to +correctly process image data with BitsPerSample greater than 8. +The library attempts to hide bit-ordering differences +between the image and the native machine by converting data +from the native machine order. +

+ +In C++ the +sample + +parameter defaults to 0. +

+ +Once data are written to a file for the current directory, +the values of certain tags may not be altered; see +TIFFSetField(3T) + +for more information. +

+ +It is not possible to write scanlines to a file that +uses a tiled organization. The routine +TIFFIsTiled + +can be used to determine if the file is organized +as tiles or strips. +  +

RETURN VALUES

+ +TIFFWriteScanline + +returns -1 if it immediately detects an error +and 1 for a successful write. +  +

DIAGNOSTICS

+ +All error messages are directed to the +TIFFError(3T) + +routine. +

+ +%s: File not open for writing . + +The file was opened for reading, not writing. +

+ +Can not write scanlines to a tiled image. + +An attempt was made to write a scanline to a tiled image. +The image is assumed to be organized in tiles because the +TileWidth + +and +TileLength + +tags have been set with +TIFFSetField(3T). + +

+ +Compression algorithm does not support random access. + +Data was written in a non-sequential order to a file that +uses a compression algorithm and that has +RowsPerStrip + +greater than one. +That is, data in the image is to be stored in a compressed form, +and with multiple rows packed into a strip. +In this case, the library does not support random access to the data. +The data should either be written as entire strips, +sequentially by rows, or the value of +RowsPerStrip + +should be set to one. +

+ +%s: Must set "ImageWidth" before writing data. +The image's width has not be set before the first write. +See +TIFFSetField(3T) + +for information on how to do this. +

+ +%s: Must set "PlanarConfiguration" before writing data. +The organization of data has not be defined before the first write. +See +TIFFSetField(3T) + +for information on how to do this. +

+ +Can not change "ImageLength" when using separate planes. +Separate image planes are being used (PlanarConfiguration=2), + +but the number of rows has not been specified before the first write. +The library supports the dynamic growth of an image only when data +are organized in a contiguous manner (PlanarConfiguration=1). + +

+ +%d: Sample out of range, max %d. + +The +sample + +parameter was greater than the value of the SamplesPerPixel tag. +

+ +%s: No space for strip arrays . + +There was not enough space for the arrays that hold strip +offsets and byte counts. +  +

BUGS

+ +Writing subsampled YCbCR data does not work correctly +because, for +PlanarConfiguration=2 + +the size of a scanline is not calculated on a per-sample basis, +and for +PlanarConfiguration=1 + +the library does not pack the block-interleaved samples. +  +

DESCRIPTION

+ +Write the data for the tile +containing + +the specified coordinates. +The data in +buf + +are is (potentially) compressed, and written to the indicated file, normally +being appended to the end of the file. +The buffer must be contain an entire tile of data. +Applications should call the routine +TIFFTileSize + +to find out the size (in bytes) of a tile buffer. +The +x + +and +y + +parameters are always used by +TIFFWriteTile. + +The +z + +parameter is used if the image is deeper than 1 slice (ImageDepth>1). + +The +sample + +parameter is used only if data are organized in separate planes (PlanarConfiguration=2). + +  +

DESCRIPTION

+ +The following routines are provided for client-control of the +I/O buffers used by the library. +Applications need never use these routines; they are provided only +for ``intelligent clients'' that wish to optimize memory usage and/or +eliminate potential copy operations that can occur when working with +images that have data stored without compression. +

+ +TIFFReadBufferSetup + +sets up the data buffer used to read raw (encoded) data from a file. +If the specified pointer is +NULL +(zero), then a buffer of the appropriate size is allocated. +Otherwise the caller must guarantee that the buffer is large +enough to hold any individual strip of raw data. +TIFFReadBufferSetup + +returns a non-zero value if the setup was successful and zero otherwise. +

+ +TIFFWriteBufferSetup + +sets up the data buffer used to write raw (encoded) data to a file. +If the specified +size + +is -1 then the buffer size is selected to hold a complete +tile or strip, or at least 8 kilobytes, whichever is greater. +If the specified +buffer + +is +NULL +(zero), then a buffer of the appropriate size is dynamically allocated. +TIFFWriteBufferSetup + +returns a non-zero value if the setup was successful and zero otherwise. +  +

DIAGNOSTICS

+ +%s: No space for data buffer at scanline %ld. + +TIFFReadBufferSetup + +was unable to dynamically allocate space for a data buffer. +

+ +%s: No space for output buffer. + +TIFFWriteBufferSetup + +was unable to dynamically allocate space for a data buffer. +  +

NAME

+ +TIFFFindCODEC, TIFFRegisterCODEC, TIFFUnRegisterCODEC - codec-related utility routines +  +

SYNOPSIS

+ +#include <tiffio.h> + +
+ +const TIFFCodec* TIFFFindCODEC(uint16 scheme); + +
+ +TIFFCodec* TIFFRegisterCODEC(uint16 scheme, const char* method, TIFFInitMethod init); + +
+ +void TIFFUnRegisterCODEC(TIFFCodec* codec); + +  +

DESCRIPTION

+ +libtiff + +supports a variety of compression schemes implemented by software +codecs. + +Each codec adheres to a modular interface that provides for +the decoding and encoding of image data; as well as some other +methods for initialization, setup, cleanup, and the control +of default strip and tile sizes. +Codecs are identified by the associated value of the +TIFF +Compression + +tag; e.g. 5 for +LZW +compression. +

+ +The +TIFFRegisterCODEC + +routine can be used to +augment or override the set of codecs available to an application. +If the specified +scheme + +already has a registered codec then it is +overridden + +and any images with data encoded with this +compression scheme will be decoded using the supplied coded. +  +

DIAGNOSTICS

+ +No space to register compression scheme %s. + +TIFFRegisterCODEC + +was unable to allocate memory for the data structures needed +to register a codec. +

+ +Cannot remove compression scheme %s; not registered. + +TIFFUnRegisterCODEC + +did not locate the specified codec in the table of registered +compression schemes. +  +

DESCRIPTION

+ +These routines are provided for writing portable software that uses +libtiff; + +they hide any memory-management related issues, such as dealing with +segmented architectures found on 16-bit machines. +

+ +_TIFFmalloc + +and +_TIFFrealloc + +are used to dynamically allocate and reallocate memory used by +libtiff; + +such as memory passed into the I/O routines. +Memory allocated through these interfaces is released back to the +system using the +_TIFFfree + +routine. +

+ +Memory allocated through one of the above interfaces can be set to +a known value using +_TIFFmemset, + +copied to another memory location using +_TIFFmemcpy, + +or compared for equality using +_TIFFmemcmp. + +These routines conform to the equivalent +ANSI +C routines: +memset, + +memcpy, + +and +memcmp, + +repsectively. +  +

+ +  +

DESCRIPTION

+ +The following routines return status information about an open +TIFF +file. +

+ +TIFFCurrentDirectory + +returns the index of the current directory (directories +are numbered starting at 0). +This number is suitable for use with the +TIFFSetDirectory + +routine. +

+ +TIFFLastDirectory + +returns a non-zero value if the current directory is the +last directory in the file; +otherwise zero is returned. +

+ +TIFFCurrentRow, + +TIFFCurrentStrip, + +and +TIFFCurrentTile, + +return the current row, strip, and tile, respectively, +that is being read or written. +These values are updated each time a read or write is done. +

+ +TIFFFileno + +returns the underlying file descriptor used to access the +TIFF +image in the filesystem. +

+ +TIFFFileName + +returns the pathname argument passed to +TIFFOpen + +or +TIFFFdOpen. + +

+ +TIFFGetMode + +returns the mode with which the underlying file was opened. +On +UNIX +systems, this is the value passed to the +open(2) + +system call. +

+ +TIFFIsTiled + +returns a non-zero value if the image data has +a tiled organization. +Zero is returned if the image data is organized in strips. +

+ +TIFFIsByteSwapped + +returns a non-zero value if the image data was in a different +byte-order than the host machine. +Zero is returned if the image data and local host byte-orders +are the same. +Data samples that are more than 8 bits wide must be byte-swapped +by the application. +

+ +TIFFIsUpSampled + +returns a non-zero value if image data returned through the +read interface routines is being up-sampled. +This can be useful to applications that want to calculate +I/O buffer sizes to reflect this usage (though the usual +strip and tile size routines already do this). +

+ +TIFFIsMSB2LSB + +returns a non-zero value if the image data is being returned with +bit 0 as the most significant bit. +

+ +TIFFGetVersion + +returns an +ASCII +string that has a version stamp for the +TIFF +library software. +  +

+ +TIFFTileRowSize + +returns the number of bytes of a row of data in a tile. +

+ +TIFFComputeTile + +returns the tile that contains the specified coordinates. +A valid tile is always returned; +out-of-range coordinate values are clamped to the bounds of the image. +The +x + +and +y + +parameters are always used in calculating a tile. +The +z + +parameter is used if the image is deeper than 1 slice (ImageDepth>1). + +The +sample + +parameter is used only if data are organized in separate planes (PlanarConfiguration=2). + +

NAME

+ +fax2ps - convert a +TIFF +facsimile to compressed POSTSCRIPTtm +  +

SYNOPSIS

+ +fax2ps + +[ +options + +] [ +file... + +] +  +

DESCRIPTION

+ +fax2ps + +reads one or more +TIFF +facsimile image files and prints a compressed form of +POSTSCRIPT on the standard output that is suitable for printing. +

+ +By default, each page is scaled to reflect the +image dimensions and resolutions stored in the file. +The +-x + +and +-y + +options can be used to specify the horizontal and vertical +image resolutions (lines/inch), respectively. +If the +-S + +option is specified, each page is scaled to fill an output page. +The default output page is 8.5 by 11 inches. +Alternate page dimensions can be specified in inches with the +-W + +and +-H + +options. +

+ +By default +fax2ps + +generates POSTSCRIPT for all pages in the file. +The +-p + +option can be used to select one or more pages from +a multi-page document. +

+ +fax2ps + +generates a compressed form of POSTSCRIPT that is +optimized for sending pages of text to a POSTSCRIPT +printer attached to a host through a low-speed link (such +as a serial line). +Each output page is filled with white and then only +the black areas are drawn. +The POSTSCRIPT specification of the black drawing operations +is optimized by using a special font that encodes the +move-draw operations required to fill +the black regions on the page. +This compression scheme typically results in a substantially +reduced POSTSCRIPT description, relative to the straightforward +imaging of the page with a POSTSCRIPT +image + +operator. +This algorithm can, however, be ineffective +for continuous-tone and white-on-black images. +For these images, it sometimes is more efficient to send +the raster bitmap image directly; see +tiff2ps(1). + +  +

OPTIONS

+ +
+
-p number + +
+Print only the indicated page. +Multiple pages may be printed by specifying +this option more than once. +
-x resolution + +
+Use +resolution + +as the horizontal resolution, in dots/inch, of the image data. +By default this value is taken from the file. +
-y resolution + +
+Use +resolution + +as the vertical resolution, in lines/inch, of the image data. +By default this value is taken from the file. +
-S + +
+Scale each page of image data to fill the output page dimensions. +By default images are presented according to the dimension +information recorded in the +TIFF +file. +
-W width + +
+Use +width + +as the width, in inches, of the output page. +The default page width is 8.5 inches. +
-H height + +
+Use +height + +as the height, in inches, of the output page. +The default page height is 11 inches. +
+  +

DIAGNOSTICS

+ +Some messages about malformed +TIFF +images come from the +TIFF +library. +

+ +Various messages about badly formatted facsimile images +may be generated due to transmission errors in received +facsimile. +fax2ps + +attempts to recover from such data errors by resynchronizing +decoding at the end of the current scanline. +This can result in long horizontal black lines in the resultant +POSTSCRIPT image. +  +

NOTES

+ +If the destination printer supports POSTSCRIPT Level II then +it is always faster to just send the encoded bitmap generated +by the +tiff2ps(1) + +program. +  +

BUGS

+ +fax2ps + +should probably figure out when it is doing a poor +job of compressing the output and just generate +POSTSCRIPT to image the bitmap raster instead. +  +

NAME

+ +fax2tiff - create a +TIFF +Class F fax file from raw fax data +  +

SYNOPSIS

+ +fax2tiff + +[ +options + +] [ +-o + +output.tif + +] +input.g3 + +  +

DESCRIPTION

+ +Fax2tiff + +creates a +TIFF +file containing +CCITT +Group 3 or Group 4 encoded data from one or more files containing ``raw'' +Group 3 encoded data (typically obtained directly from a fax modem). +By default, each row of data in the resultant +TIFF +file is 2-dimensionally encoded and +padded or truncated to 1728 pixels, as needed. +The resultant image is a set of low resolution (98 lines/inch) +or medium resolution (196 lines/inch) +pages, each of which is a single strip of data. +The generated file conforms to the +TIFF +Class F (FAX) specification for storing facsimile data. +This means, in particular, that each page of the data does +not + +include the trailing +return to control + +(RTC) code; as required +for transmission by the +CCITT +Group 3 specifications. +The old, ``classic'', format is created if the +-c + +option is used. +(The Class F format can also be requested with the +-f + +option.) +

+ +The default name of the output image is +fax.tif; + +this can be changed with the +-o + +option. +Each input file is assumed to be a separate page of facsimile data +from the same document. +The order in which input files are specified on the command +line is the order in which the resultant pages appear in the +output file. +  +

OPTIONS

+ +Options that affect the interpretation of input data are: +
+
-2 + +
+Assume input data is 2-d Huffman encoded. +
-B + +
+Assume input data was encoded with +black as 0 and white as 1. +
-L + +
+Treat input data as having bits filled from least +significant bit (LSB) to most significant bit (MSB). +(This is the default.) +
-M + +
+Treat input data as having bits filled from most +significant bit (MSB) to most least bit (LSB). +
-R + +
+Specify the vertical resolution, in lines/inch, of the +input images. +By default input are assumed to have a vertical +resolution of 196 lines/inch. +If images are low resolution facsimile, a value of +98 lines/inch should be specified. +
-W + +
+Assume input data was encoded with +black as 1 and white as 0. +(This is the default.) +
+

+ +Options that affect the output file format are: +

+
-1 + +
+Force output to be compressed with the 1-dimensional +version of the +CCITT +Group 3 Huffman encoding algorithm. +
-4 + +
+Force output to be compressed with the +CCITT +Group 4 Huffman encoding. +
-o + +
+Specify the name of the output file. +
-p + +
+Force the last bit of each +End Of Line + +(EOL) code to land on a byte boundary. +This ``zero padding'' will be reflected in the contents of the +Group3Options + +tag of the resultant +TIFF +file. +
-s + +
+Stretch the input image vertically by writing each input row of +data twice to the output file. +
-v + +
+Force +fax2tiff + +to print the number of rows of data it retrieved from the input file. +
+  +

DIAGNOSTICS

+ +The following warnings and errors come from the decoding +routines in the library. +

+ +Warning, %s: Premature EOL at scanline %d (x %d).\n. + +The input data had a row that was shorter than the expected value of 1728. +The row is padded with white. +

+ +%s: Premature EOF at scanline %d (x %d).\n. + +The decoder ran out of data in the middle of a scanline. +The resultant row is padded with white. +

+ +%s: Bad code word at row %d, x %d\n. + +An invalid Group 3 +code + +was encountered while decoding the input file. +The row number and horizontal position is given. +The remainder of the input row is discarded, while +the corresponding output row is padded with white. +

+ +%s: Bad 2D code word at scanline %d.\n. + +An invalid Group 4 or 2D Group 3 +code + +was encountered while decoding the input file. +The row number and horizontal position is given. +The remainder of the input row is discarded, while +the corresponding output row is padded with white. +  +

BUGS

+ +Should not have the constant width 1728 built into it. +Input data are assumed to have a a ``top left'' orientation; +it should be possible to override this assumption +from the command line. +  +

NAME

+ +gif2tiff - create a +TIFF +file from a GIF87 format image file +  +

SYNOPSIS

+ +gif2tiff + +[ +options + +] +input.gif + +output.tif + +  +

DESCRIPTION

+ +Gif2tiff + +converts a file in the GIF87 format to +TIFF. +The +TIFF +image is created as a palette image, with samples +compressed with the Lempel-Ziv & Welch algorithm (Compression=5). + +These characteristics can overriden, or explicitly specified +with the options described below. +  +

OPTIONS

+ +
+
-c + +
+Specify a compression scheme to use when writing image data: +-c none + +for no compression, +-c packbits + +for the PackBits compression algorithm, +-c zip + +for the Deflate compression algorithm, +and +-c lzw + +for Lempel-Ziv & Welch (the default). +
-r + +
+Write data with a specified number of rows per strip; +by default the number of rows/strip is selected so that each strip +is approximately 8 kilobytes. +
+  +

NOTES

+ +The program is based on Paul Haeberli's +fromgif + +program which, in turn, is based on Marcel J.E. Mol's GIF reader. +  +

BUGS

+ +Should have more options to control output format. +  +

NAME

+ +libtiff - introduction to +libtiff, + +a library for reading and writing +TIFF +files +  +

SYNOPSIS

+ +#include <tiffio.h> + +
+ +cc file.c +-ltiff + +  +

DESCRIPTION

+ +libtiff + +is a library for reading and writing data files encoded with the +Tag Image File + +format, Revision 6.0 (or revision 5.0 or revision 4.0). +This file format is suitable for archiving multi-color and +monochromatic image data. +

+ +The library supports several compression algorithms, as indicated +by the +Compression + +field, including: +no compression (1), +CCITT +1D Huffman compression (2), +CCITT +Group 3 Facsimile compression (3), +CCITT +Group 4 Facsimile compression (4), +Lempel-Ziv & Welch compression (5), +baseline JPEG compression (7), +word-aligned 1D Huffman compression (32771), +and +PackBits compression (32773). +In addition, several nonstandard compression algorithms are supported: +the 4-bit compression algorithm used +by the +ThunderScan + +program (32809) (decompression only), +NeXT's 2-bit compression algorithm (32766) (decompression only), +an experimental LZ-style algorithm known as Deflate (32946), and +an experimental CIE LogLuv compression scheme designed for images +with high dynamic range (32845 for LogL and 32845 for LogLuv). +Directory information may be in either little- or big-endian byte +order-byte swapping is automatically done by the library. +Data bit ordering may be either Most Significant Bit (MSB) to Least Significant Bit (LSB) or +LSB +to +MSB. +Finally, the library does not support files in which the +BitsPerSample, + +Compression, + +MinSampleValue, + +or +MaxSampleValue + +fields are defined differently on a per-sample basis +(in Rev. 6.0 the +Compression + +tag is not defined on a per-sample basis, so this is immaterial). +  +

DATA TYPES

+ +The library makes extensive use of C typedefs to promote portability. +Two sets of typedefs are used, one for communication with clients +of the library and one for internal data structures and parsing of the +TIFF +format. +The following typedefs are exposed to users either through +function definitions or through parameters passed through the +varargs interfaces. + +

+ + +

+typedef unsigned short uint16;        16-bit unsigned integer
+typedef unsigned <thing> uint32;      32-bit unsigned integer
+
+typedef unsigned int ttag_t;          directory tag
+typedef uint16 tdir_t;                directory index
+typedef uint16 tsample_t;             sample number
+typedef uint32 tstrip_t;              strip number
+typedef uint32 ttile_t;               tile number
+typedef int32 tsize_t;                i/o size in bytes
+typedef void* tdata_t;                image data ref
+typedef void* thandle_t;              client data handle
+typedef int32 toff_t;                 file offset
+
+ +

+ +Note that +tstrip_t, + +ttile_t, + +and +tsize_t + +are constrained to be no more than 32-bit quantities by +32-bit fields they are stored in in the +TIFF +image. +Likewise +tsample_t + +is limited by the 16-bit field used to store the +SamplesPerPixel + +tag. +tdir_t + +constrains the maximum number of +IFDs +that may appear in an image and may be an arbitrary size (w/o penalty). +ttag_t + +must be either int, unsigned int, pointer, or double because +the library uses a varargs interface and +ANSI C +restricts the type of the parameter before an ellipsis to be a +promoted type. +toff_t + +is defined as int32 because TIFF file offsets are (unsigned) 32-bit +quantities. +A signed value is used because some interfaces return -1 on error. +Finally, note that user-specified data references are +passed as opaque handles and only cast at the lowest layers where +their type is presumed. +  +

LIST OF ROUTINES

+ +The following routines are part of the library. +Consult specific manual pages for details on their operation. +The manual page names listed below are for systems +where the full function names can not be encoded in the filesystem; +on most systems doing ``man function-name'' will work. +

TAG USAGE

+ +The table below lists the +TIFF +tags that are recognized and handled by the library. +If no use is indicated in the table, then the library +reads and writes the tag, but does not use it internally. +Note that some tags are meaningful only when a particular +compression scheme is being used; e.g. +Group3Options + +is only useful if +Compression + +is set to +CCITT +Group 3 encoding. +Tags of this sort are considered +codec-specific + +tags and the library does not recognize them except when the +Compression + +tag has been previously set to the relevant compression scheme. +

PSEUDO TAGS

+ +In addition to the normal +TIFF +tags the library supports a collection of +tags whose values lie in a range outside the valid range of +TIFF +tags. +These tags are termed +pseud-tags + +and are used to control various codec-specific functions within the library. +The table below summarizes the defined pseudo-tags. +

+

+
+Tag Name                Codec  R/W  Library Use/Notes
+
+TIFFTAG_FAXMODE         G3     R/W  general codec operation
+TIFFTAG_FAXFILLFUNC     G3/G4  R/W  bitmap fill function
+TIFFTAG_JPEGQUALITY     JPEG   R/W  compression quality control
+TIFFTAG_JPEGCOLORMODE   JPEG   R/W  control colorspace conversions
+TIFFTAG_JPEGTABLESMODE  JPEG   R/W  control contents of JPEGTables tag
+TIFFTAG_ZIPQUALITY      Deflate     R/Wcompression quality level
+TIFFTAG_PIXARLOGDATAFMT PixarLog    R/Wuser data format
+TIFFTAG_PIXARLOGQUALITY PixarLog    R/Wcompression quality level
+TIFFTAG_SGILOGDATAFMT   SGILog R/W  user data format
+
+ +
+
TIFFTAG_FAXMODE + +
+Control the operation of the Group 3 codec. +Possible values (independent bits that can be combined by +or'ing them together) are: +FAXMODE_CLASSIC +(enable old-style format in which the +RTC +is written at the end of the last strip), +FAXMODE_NORTC +(opposite of +FAXMODE_CLASSIC; +also called +FAXMODE_CLASSF), +FAXMODE_NOEOL +(do not write +EOL +codes at the start of each row of data), +FAXMODE_BYTEALIGN +(align each encoded row to an 8-bit boundary), +FAXMODE_WORDALIGN +(align each encoded row to an 16-bit boundary), +The default value is dependent on the compression scheme; this +pseudo-tag is used by the various G3 and G4 codecs to share code. +
TIFFTAG_FAXFILLFUNC + +
+Control the function used to convert arrays of black and white +runs to packed bit arrays. +This hook can be used to image decoded scanlines in multi-bit +depth rasters (e.g. for display in colormap mode) +or for other purposes. +The default value is a pointer to a builtin function that images +packed bilevel data. +
TIFFTAG_IPTCNEWSPHOTO + +
+Tag contaings image metadata per the IPTC newsphoto spec: Headline, +captioning, credit, etc... Used by most wire services. +
TIFFTAG_PHOTOSHOP + +
+Tag contains Photoshop captioning information and metadata. Photoshop +uses in parallel and redundantly alongside IPTCNEWSPHOTO information. +
TIFFTAG_JPEGQUALITY + +
+Control the compression quality level used in the baseline algorithm. +Note that quality levels are in the range 0-100 with a default value of 75. +
TIFFTAG_JPEGCOLORMODE + +
+Control whether or not conversion is done between +RGB and YCbCr colorspaces. +Possible values are: +JPEGCOLORMODE_RAW +(do not convert), and +JPEGCOLORMODE_RGB +(convert to/from RGB) +The default value is JPEGCOLORMODE_RAW. +
TIFFTAG_JPEGTABLESMODE + +
+Control the information written in the +JPEGTables + +tag. +Possible values (independent bits that can be combined by +or'ing them together) are: +JPEGTABLESMODE_QUANT +(include quantization tables), +and +JPEGTABLESMODE_HUFF +(include Huffman encoding tables). +The default value is JPEGTABLESMODE_QUANT|JPEGTABLESMODE_HUFF. +
TIFFTAG_ZIPQUALITY + +

NAME

+ +pal2rgb - convert a palette color +TIFF +image to a full color image +  +

SYNOPSIS

+ +pal2rgb + +[ +options + +] +input.tif + +output.tif + +  +

DESCRIPTION

+ +Pal2rgb + +converts a palette color +TIFF +image to a full color image by +applying the colormap of the palette image to each sample +to generate a full color +RGB +image. +  +

OPTIONS

+ +Options that affect the interpretation of input data are: +
+
-C + +
+This option overrides the default behaviour of +pal2rgb + +in determining whether or not +colormap entries contain 16-bit or 8-bit values. +By default the colormap is inspected and +if no colormap entry greater than 255 is found, +the colormap is assumed to have only 8-bit values; otherwise +16-bit values (as required by the +TIFF +specification) are assumed. +The +-C + +option can be used to explicitly specify the number of +bits for colormap entries: +-C 8 + +for 8-bit values, +-C 16 + +for 16-bit values. +
+

+ +Options that affect the output file format are: +

+
-p + +
+Explicitly select the planar configuration used in organizing +data samples in the output image: +-p contig + +for samples packed contiguously, and +-p separate + +for samples stored separately. +By default samples are packed. +
-c + +
+Use the specific compression algorithm to encoded image data +in the output file: +-c packbits + +for Macintosh Packbits, +-c lzw + +for Lempel-Ziv & Welch, +-c zip + +for Deflate, +-c none + +for no compression. +If no compression-related option is specified, the input +file's compression algorithm is used. +
-r + +
+Explicitly specify the number of rows in each strip of the +output file. +If the +-r + +option is not specified, a number is selected such that each +output strip has approximately 8 kilobytes of data in it. +
+  +

BUGS

+ +Only 8-bit images are handled. +  +

+ +If the +PPM +file contains greyscale data, then the +PhotometricInterpretation + +tag is set to 1 (min-is-black), +otherwise it is set to 2 (RGB). +

+ +If no +PPM +file is specified on the command line, +ppm2tiff + +will read from the standard input. +  +

OPTIONS

+ +
+
-c + +
+Specify a compression scheme to use when writing image data: +-c none + +for no compression, +-c packbits + +for the PackBits compression algorithm, +-c jpeg + +for the baseline JPEG compression algorithm, +-c zip + +for the Deflate compression algorithm, +and +-c lzw + +for Lempel-Ziv & Welch compression (the default). +

DESCRIPTION

+ +thumbnail + +is a program written to show how one might use the +SubIFD tag (#330) to store thumbnail images. +thumbnail + +copies a +TIFF +Class F facsimile file to the output file +and for each image an 8-bit greyscale +thumbnail sketch. + +The output file contains the thumbnail image with the associated +full-resolution page linked below with the SubIFD tag. +

+ +By default, thumbnail images are 216 pixels wide by 274 pixels high. +Pixels are calculated by sampling and filtering the input image +with each pixel value passed through a contrast curve. +  +

OPTIONS

+ +
+
-w + +
+Specify the width of thumbnail images in pixels. +
-h + +
+Specify the height of thumbnail images in pixels. +
-c + +
+Specify a contrast curve to apply in generating the thumbnail images. +By default pixels values are passed through a linear contrast curve +that simply maps the pixel value ranges. +Alternative curves are: +exp50 + +for a 50% exponential curve, +exp60 + +for a 60% exponential curve, +exp70 + +for a 70% exponential curve, +exp80 + +for a 80% exponential curve, +exp90 + +for a 90% exponential curve, +exp + +for a pure exponential curve, +linear + +for a linear curve. +

NAME

+ +tiff2ps - convert a +TIFF +image to POSTSCRIPTtm +  +

SYNOPSIS

+ +tiff2ps + +[ +options + +] +input.tif ... + +  +

DESCRIPTION

+ +tiff2ps + +reads +TIFF +images and writes POSTSCRIPT or Encapsulated POSTSCRIPT (EPS) +on the standard output. +By default, +tiff2ps + +writes Encapsulated POSTSCRIPT for the first image in the specified +TIFF +image file. +

+ +By default, +tiff2ps + +will generate POSTSCRIPT that fills a printed area specified +by the +TIFF +tags in the input file. +If the file does not contain +XResolution + +or +YResolution + +tags, then the printed area is set according to the image dimensions. +The +-w + +and +-h + +options (see below) +can be used to set the dimensions of the printed area in inches; +overriding any relevant +TIFF +tags. +

+ +The POSTSCRIPT generated for +RGB, +palette, and +CMYK +images uses the +colorimage + +operator. +The POSTSCRIPT generated for +greyscale and bilevel images +uses the +image + +operator. +When the +colorimage + +operator is used, POSTSCRIPT code to emulate this operator +on older POSTSCRIPT printers is also generated. +Note that this emulation code can be very slow. +

+ +Color images with associated alpha data are composited over +a white background. +  +

OPTIONS

+ +
+
-1 + +
+Generate POSTSCRIPT Level I (the default). +
-2 + +
+Generate POSTSCRIPT Level II. +
-a + +
+Generate output for all IFDs (pages) in the input file. +
-d + +
+Set the initial +TIFF +directory to the specified directory number. +(NB: directories are numbered starting at zero.) +This option is useful for selecting individual pages in a +multi-page (e.g. facsimile) file. +
-e + +
+Force the generation of Encapsulated POSTSCRIPT. +
-h + +
+Specify the vertical size of the printed area (in inches). +
-o + +
+Set the initial +TIFF +directory to the +IFD +at the specified file offset. +This option is useful for selecting thumbnail images and the +like which are hidden using the SubIFD tag. +
-p + +
+Force the generation of (non-Encapsulated) POSTSCRIPT. +
-s + +
+Generate output for a single IFD (page) in the input file. +
-w + +
+Specify the horizontal size of the printed area (in inches). +
-z + +
+When generating POSTSCRIPT Level II, data is scaled so that it does not +image into the +deadzone + +on a page (the outer margin that the printing device is unable to mark). +This option suppresses this behaviour. +When POSTSCRIPT Level I is generated, data is imaged to the entire printed +page and this option has no affect. +
+  +

EXAMPLES

+ +The following generates POSTSCRIPT Level II for all pages of a facsimile: +
+
+tiff2ps -a2 fax.tif | lpr
+
+ +
+ +Note also that if you have version 2.6.1 or newer of Ghostscript then you +can efficiently preview facsimile generated with the above command. +

+ +To generate Encapsulated POSTSCRIPT for a the image at directory 2 +of an image use: +

+
+tiff2ps -d 1 foo.tif
+
+ +
+ +(notice that directories are numbered starting at zero.) +  +

BUGS

+ +Because POSTSCRIPT does not support the notion of a colormap, +8-bit palette images produce 24-bit POSTSCRIPT images. +This conversion results in output that is six times +bigger than the original image and which takes a long time +to send to a printer over a serial line. +Matters are even worse for 4-, 2-, and 1-bit palette images. +  +

BUGS

+ +Does not handle tiled images when generating PS Level I output. +  +

+ +tiffcp + +combines one or more files created according +to the Tag Image File Format, Revision 6.0 +into a single +TIFF +file. +Because the output file may be compressed using a different +algorithm than the input files, +tiffcp + +is most often used to convert between different compression +schemes. +

+ +By default, +tiffcp + +will copy all the understood tags in a +TIFF +directory of an input +file to the associated directory in the output file. +

+ +tiffcp + +can be used to reorganize the storage characteristics of data +in a file, but it is explicitly intended to not alter or convert +the image data content in any way. +  +

OPTIONS

+ +
+
-B + +
+Force output to be written with Big-Endian byte order. +This option only has an effect when the output file is created or +overwritten and not when it is appended to. +
-C + +
+Suppress the use of ``strip chopping'' when reading images +that have a single strip/tile of uncompressed data. +
-c + +
+Specify the compression to use for data written to the output file: +none + +for no compression, +packbits + +for PackBits compression, +lzw + +for Lempel-Ziv & Welch compression, +jpeg + +for baseline JPEG compression, +zip + +for Deflate compression, +g3 + +for CCITT Group 3 (T.4) compression, +and +g4 + +for CCITT Group 4 (T.6) compression. +By default +tiffcp + +will compress data according to the value of the +Compression + +tag found in the source file. +
+The +CCITT +Group 3 and Group 4 compression algorithms can only +be used with bilevel data. +
+Group 3 compression can be specified together with several +T.4-specific options: +1d + +for 1-dimensional encoding, +2d + +for 2-dimensional encoding, +and +fill + +to force each encoded scanline to be zero-filled so that the +terminating EOL code lies on a byte boundary. +Group 3-specific options are specified by appending a ``:''-separated +list to the ``g3'' option; e.g. +-c g3:2d:fill + +to get 2D-encoded data with byte-aligned EOL codes. +
+LZW +compression can be specified together with a +predictor + +value. +A predictor value of 2 causes +each scanline of the output image to undergo horizontal +differencing before it is encoded; a value +of 1 forces each scanline to be encoded without differencing. +LZW-specific options are specified by appending a ``:''-separated +list to the ``lzw'' option; e.g. +-c lzw:2 + +for +LZW +compression with horizontal differencing. +
-f + +
+Specify the bit fill order to use in writing output data. +By default, +tiffcp + +will create a new file with the same fill order as the original. +Specifying +-f lsb2msb + +will force data to be written with the FillOrder tag set to +LSB2MSB, +while +-f msb2lsb + +will force data to be written with the FillOrder tag set to +MSB2LSB. +
-l + +
+Specify the length of a tile (in pixels). +tiffcp + +attempts to set the tile dimensions so +that no more than 8 kilobytes of data appear in a tile. +
-L + +
+Force output to be written with Little-Endian byte order. +This option only has an effect when the output file is created or +overwritten and not when it is appended to. +
-M + +
+Suppress the use of memory-mapped files when reading images. +
-p + +
+Specify the planar configuration to use in writing image data +that has one 8-bit sample per pixel. +By default, +tiffcp + +will create a new file with the same planar configuration as +the original. +Specifying +-p contig + +will force data to be written with multi-sample data packed +together, while +-p separate + +will force samples to be written in separate planes. +
-r + +
+Specify the number of rows (scanlines) in each strip of data +written to the output file. +By default, +tiffcp + +attempts to set the rows/strip +that no more than 8 kilobytes of data appear in a strip. +
-s + +
+Force the output file to be written with data organized in strips +(rather than tiles). +
-t + +
+Force the output file to be written wtih data organized in tiles +(rather than strips). +options can be used to force the resultant image to be written +as strips or tiles of data, respectively. +
-w + +
+Specify the width of a tile (in pixels). +tiffcp + +attempts to set the tile dimensions so +that no more than 8 kilobytes of data appear in a tile. +
+  +

EXAMPLES

+ +The following concatenates two files and writes the result using +LZW +encoding: +
+
+tiffcp -c lzw a.tif b.tif result.tif
+
+ +
+ +

+ +To convert a G3 1d-encoded +TIFF +to a single strip of G4-encoded data the following might be used: +

+
+tiffcp -c g4 -r 10000 g3.tif g4.tif
+
+ +
+ +(1000 is just a number that is larger than the number of rows in +the source file.) +  +

SYNOPSIS

+ +tiffdump + +[ +options + +] +name ... + +  +

DESCRIPTION

+ +tiffdump + +displays directory information from files created according +to the Tag Image File Format, Revision 6.0. +The header of each +TIFF +file (magic number, version, and first directory offset) +is displayed, followed by the tag contents of each directory in the file. +For each tag, the name, datatype, count, and value(s) is displayed. +When the symbolic name for a tag or datatype is known, the symbolic +name is displayed followed by it's numeric (decimal) value. +Tag values are displayed enclosed in ``<>'' characters immediately +preceded by the value of the count field. +For example, an +ImageWidth + +tag might be displayed as ``ImageWidth (256) SHORT (3) 1<800>''. +

+ +tiffdump + +is particularly useful for investigating the contents of +TIFF +files that +libtiff + +does not understand. +  +

OPTIONS

+ +
+
-h + +
+Force numeric data to be printed in hexadecimal rather than the +default decimal. +
-o + +
+Dump the contents of the +IFD +at the a particular file offset. +The file offset may be specified using the usual C-style syntax; +i.e. a leading ``0x'' for hexadecimal and a leading ``0'' for octal. +

NAME

+ +tiffgt - display an image stored in a +TIFF +file (Silicon Graphics version) +  +

SYNOPSIS

+ +tiffgt + +[ +options + +] +input.tif ... + +  +

DESCRIPTION

+ +tiffgt + +displays one or more images stored using the +Tag Image File Format, Revision 6.0. +Each image is placed in a fixed size window that the +user must position on the display (unless configured +otherwise through X defaults). +If the display has fewer than 24 bitplanes, or if the +image does not warrant full color, then +RGB +color values are mapped to the closest values that exist in +the colormap (this is done using the +rgbi + +routine found in the graphics utility library +-lgutil.) + +

+ +tiffgt + +correctly handles files with any of the following characteristics: +

+ + + +

+BitsPerSample                1, 2, 4, 8, 16
+SamplesPerPixel              1, 3, 4 (the 4th sample is ignored)
+PhotometricInterpretation    0 (min-is-white), 1 (min-is-black), 2 (RGB), 3 (palette), 6 (YCbCr)
+PlanarConfiguration          1 (contiguous), 2 (separate)
+Orientation                  1 (top-left), 4 (bottom-left)
+
+ + +

+Data may be organized as strips or tiles and may be +compressed with any of the compression algorithms supported +by the +libtiff(3) + +library. +

+ +For palette images (PhotomatricInterpretation=3), + +tiffgt + +inspects the colormap values and assumes either 16-bit +or 8-bit values according to the maximum value. +That is, if no colormap entry greater than 255 is found, +tiffgt + +assumes the colormap has only 8-bit values; otherwise +it assumes 16-bit values. +This inspection is done to handle old images written by +previous (incorrect) versions of +libtiff. + +

+ +tiffgt + +can be used to display multiple images one-at-a-time. +The left mouse button switches the display to the first image in the +next + +file in the list of files specified on the command line. +The right mouse button switches to the first image in the +previous + +file in the list. +The middle mouse button causes the first image in the first file +specified on the command line to be displayed. +In addition the following keyboard commands are recognized: +

+
b + +
+Use a +PhotometricIntepretation + +of MinIsBlack in displaying the current image. +
l + +
+Use a +FillOrder + +of lsb-to-msb in decoding the current image. +
m + +
+Use a +FillOrder + +of msb-tolmsb in decoding the current image. +
c + +
+Use a colormap visual to display the current image. +
r + +
+Use a true color (24-bit RGB) visual to display the current image. +
w + +
+Use a +PhotometricIntepretation + +of MinIsWhite in displaying the current image. +
W + +
+Toggle (enable/disable) display of warning messages from the +TIFF +library when decoding images. +
E + +
+Toggle (enable/disable) display of error messages from the +TIFF +library when decoding images. +
z + +
+Reset all parameters to their default settings (FillOrder, + +PhotometricInterpretation, + +handling of warnings and errors). +
PageUp + +
+Display the previous image in the current file or the last +image in the previous file. +
PageDown + +
+Display the next image in the current file or the first image +in the next file. +
Home + +
+Display the first image in the current file. +
End + +
+Display the last image in the current file (unimplemented). +
+  +

OPTIONS

+ +
+
-c + +
+Force image display in a colormap window. +
-d + +
+Specify an image to display by directory number. +By default the first image in the file is displayed. +Directories are numbered starting at zero. +
-e + +
+Enable reporting of error messages from the +TIFF +library. +By default +tiffgt + +silently ignores images that cannot be read. +
-f + +
+Force +tiffgt + +to run as a foreground process. +By default +tiffgt + +will place itself in the background once it has opened the +requested image file. +
-l + +
+Force the presumed bit ordering to be +LSB +to +MSB. +
-m + +
+Force the presumed bit ordering to be +MSB +to +LSB. +
-o + +
+Specify an image to display by directory offset. +By default the first image in the file is displayed. +Directories offsets may be specified using C-style syntax; +i.e. a leading ``0x'' for hexadecimal and a leading ``0'' for octal. +
-p + +
+Override the value of the +PhotometricInterpretation + +tag; the parameter may be one of: +miniswhite, + +minisblack, + +rgb, + +palette, + +mask, + +separated, + +ycbcr, + +and +cielab. + +
-r + +
+Force image display in a full color window. +
-s + +
+Stop on the first read error. +By default all errors in the input data are ignored and +tiffgt + +does it's best to display as much of an image as possible. +
-w + +
+Enable reporting of warning messages from the +TIFF +library. +By default +tiffgt + +ignores warning messages generated when reading an image. +
-v + +
+Place information in the title bar describing +what type of window (full color or colormap) is being +used, the name of the input file, and the directory +index of the image (if non-zero). +By default, the window type is not shown in the title bar. +
+  +

BUGS

+ +Images wider and taller than the display are silently truncated to avoid +crashing old versions of the window manager. +  +

DESCRIPTION

+ +tiffmedian + +applys the median cut algorithm to an +RGB +image in +input.tif + +to generate a palette image that is written to +output.tif. + +The generated colormap has, by default, 256 entries. +The image data is quantized by mapping each +pixel to the closest color values in the colormap. +  +

NAME

+ +tiffsv - save an image from the framebuffer in a +TIFF +file (Silicon Graphics version) +  +

SYNOPSIS

+ +tiffsv + +[ +options + +] +output.tif + +[ +x1 x2 y1 y2 + +] +  +

DESCRIPTION

+ +tiffsv + +saves all or part of the framebuffer in a file using the +Tag Image File Format, Revision 6.0. +By default, the image is saved with data samples packed (PlanarConfiguration=1), + +compressed with the Lempel-Ziv & Welch algorithm (Compression=5), + +and with each strip no more than 8 kilobytes. +These characteristics can be overriden, or explicitly specified +with the options described below. +  +

OPTIONS

+ +
+
-b + +
+Save the image as a greyscale image +as if it were processed by +tiff2bw(1). + +This option is included for compatibility with the standard +scrsave(6D) + +program. +
-c + +
+Specify the compression to use for data written to the output file: +none + +for no compression, +packbits + +for PackBits compression, +jpeg + +for baseline JPEG compression, +zip + +for Deflate compression, +and +lzw + +for Lempel-Ziv & Welch compression (default). +
+LZW +compression can be specified together with a +predictor + +value. +A predictor value of 2 causes +each scanline of the output image to undergo horizontal +differencing before it is encoded; a value +of 1 forces each scanline to be encoded without differencing. +LZW-specific options are specified by appending a ``:''-separated +list to the ``lzw'' option; e.g. +-c lzw:2 + +for +LZW +compression with horizontal differencing. +
-p + +
+Specify the planar configuration to use in writing image data. +By default, +tiffsv + +will create a new file with the data samples packed contiguously. +Specifying +-p contig + +will force data to be written with multi-sample data packed +together, while +-p separate + +will force samples to be written in separate planes. +
-r + +
+Specify the number of rows (scanlines) in each strip of data +written to the output file. +By default, +tiffsv + +attempts to set the rows/strip +that no more than 8 kilobytes of data appear in a strip. +
+  +

NOTE

+ +Except for the use of +TIFF, +this program is equivalent to the standard +scrsave + +program. +This means, for example, that you can use it in conjunction with +the standard +icut + +program simply by creating a link called +scrsave, + +or by creating a shell script called +scrsave + +that invokes +tiffgt + +with the appropriate options. +  +

BUGS

+ +If data are saved compressed and in separate planes, then the +rows in each strip is silently set to one to avoid limitations +in the +libtiff(3) + +library. +  +

Warning

+ +It appears that Unisys is actively pursuing copyright control on the +LZW compression algorithm. In particular, users of the LZW compression +within the TIFF framework. For this reason the TIFF 6.0 spec states +that LZW compression is not recommended. It is unclear at this time +what compression algorithm will be used in place of it. I have no idea +what this means to you or to this library. I make no warranty or +guarantees with regard to the LZW support in this library. + + +

+ +TIFF 6.0 Specification Coverage +

+ + +

+The library is capable of dealing with images that are written to +follow the 5.0 or 6.0 TIFF spec. There is also considerable support +for some of the more esoteric portions of the 6.0 TIFF spec. + +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
+Core requirements + +Both "MM" and "II" byte orders are handled. +Both packed and separated planar configuration of samples. +Any number of samples per pixel (memory permitting). +Any image width and height (memory permitting). +Multiple subfiles can be read and written. +Editing is not supported in that related subfiles (e.g. +a reduced resolution version of an image) are not automatically +updated. +

+Tags handled: +ExtraSamples, +ImageWidth, +ImageLength, +NewSubfileType, +ResolutionUnit. +Rowsperstrip, +StripOffsets, +StripByteCounts, +XResolution, +YResolution, +

+In addition, the library supports some optional compression algorithms +that are, in some cases, of dubious value. + +

+    Compression = 34676	SGI 32-bit Log Luminance encoding (experimental)
+    Compression = 34677	SGI 24-bit Log Luminance encoding (experimental)
+
+ +Note that there is no support for the JPEG-related tags defined +in the 6.0 specification; the JPEG support is based on the post-6.0 +proposal given in TIFF Technical Note #2. + +

+ + + + + +
+ +For more information on the experimental Log Luminance encoding +consult the materials available at +http://www.sgi.com/Technology/pixformat. + +
+ +

+The following table shows the tags that are recognized +and how they are used by the library. If no use is indicated, +then the library +reads and writes the tag, but does not use it internally. + +

+The Matteing and DataType +tags have been obsoleted by the 6.0 +ExtraSamples and SampleFormat tags. +Consult the documentation on the +ExtraSamples tag and Associated Alpha for elaboration. Note however +that if you use Associated Alpha, you are expected to save data that is +pre-multipled by Alpha. If this means nothing to you, check out +Porter & Duff's paper in the '84 SIGGRAPH proceedings: "Compositing Digital +Images". + +

+The ImageDepth +tag is a non-standard, but registered tag that specifies +the Z-dimension of volumetric data. The combination of ImageWidth, +ImageLength, and ImageDepth, +defines a 3D volume of pixels that are +further specified by BitsPerSample and +SamplesPerPixel. The TileDepth +tag (also non-standard, but registered) can be used to specified a +subvolume "tiling" of a volume of data. + +

+The Colorimetry, and CMYK tags are additions that appear in TIFF 6.0. +Consult the TIFF 6.0 specification included in the doc directory +and online. + +

+The JPEG-related tag is specified in +TIFF Technical Note #2 which defines +a revised JPEG-in-TIFF scheme (revised over that appendix that was +part of the TIFF 6.0 specification). + + + +

+ +TIFF Tools Overview +

+ +

+This software distribution comes with a small collection of programs +for converting non-TIFF format images to TIFF and for manipulating +and interogating the contents of TIFF images. +Several of these tools are useful in their own right. +Many of them however are more intended to serve as programming +examples for using the TIFF library. + +

Device-dependent Programs

+ +There are two device-dependent programs that serve as simple examples +for writing programs to display and save TIFF images. + + +

+ + + + + + + + + + + + +
tiffgt    Display the contents of one or +more TIFF images on a Silicon Graphics system using +the Silicon Graphics IRIS GL. +The software makes extensive use of the TIFFRGBAImage +facilities described elsewhere.
tiffsvA program to save all or part of a screen dump on a Silicon +Graphics system. +As for tiffgt this code, while written to use the IRIS GL, +can be easily tailored to other devices.
+ +

Device-independent Programs

+ +The remaining programs should be device-independent: + +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
tiffinfoDisplay information about one or more TIFF files.
tiffdumpDisplay the verbatim contents of the TIFF directory in a + file (it's very useful for debugging bogus files that you may get from + someone that claims they support TIFF)
tiffcpCopy, concatenate, and convert TIFF images (e.g. + switching from Compression=5 to Compression=1)
tiff2psConvert TIFF images to PostScript
tiffcmpCompare the contents of two TIFF files (it does + not check all the directory information, but does check all the data)
tiff2bwA simple program to convert a color image to grayscale
ras2tiffA quick hack that converts Sun rasterfile format images to + TIFF -- it's less than complete
rgb2ycbcrConvert an RGB, grayscale, or bilevel TIFF image to a + YCbCr TIFF image; it's mainly provided for testing
gif2tiffA quick hack that converts GIF 87a format images to TIFF
ppm2tiffA quick hack that converts PPM format images to TIFF
fax2tiffConvert raw Group 3 or Group 4 facsimile data to TIFF
pal2rgbConvert a Palette-style image to a full color RGB image by + applying the colormap
tiffditherDither a b&w image into a bilevel image (suitable for + use in creating fax files)
tiffsplitCreate one or more single-image files from a (possibly) + multi-image file
fax2psConvert a Group 3- or Group 4- compressed TIFF to PostScript + that is significantly more compressed than is generated by tiff2ps + (unless tiff2ps writes PS Level II)
thumbnailCopy a bilevel TIFF to one that includes 8-bit greyscale + "thumbnail images" for each page; it is provided as an example of + how one might use the SubIFD tag + (and the library support for it)
tiffmedianA version of Paul Heckbert's median cut program + that reads an RGB TIFF image, and creates a TIFF palette file as a + result; it's useful for converting full-color RGB images to 8-bit + color for your friends that have cheapo 8-bit framebuffers.
sgi2tiffA program to convert SGI image files to TIFF. This + program is only useful on SGI machines as it uses -limage.
+ +

+Check out the manual pages for details about the above programs. + + +

+ +

+ +CHANGES IN THE SOFTWARE CONFIGURATION: + +
    +
  • a -noninteractive flag was added to configure to + control whether or not it prints and prompts for configuration information +
  • various typos and fixes were made in configure for the the + library-only build support (this and other configure fixes from + Richard Mlynarik <mly@adoc.xerox.com>) +
  • bugs were fixed in the handling of pathnames supplied for external + packages; e.g. DIR_JPEG +
  • the handling of SETMAKE is now done properly +
  • the default prototype function declaration for pow was corrected +
  • a bug was fixed in libtiff/Makefile.in that caused installation + to fail on systems without DSO support +
+ +

+ +CHANGES IN LIBTIFF: + +
    +
  • Acorn RISC O/S support that was accidentally left out of the + left out of the previous distribution is present (from Peter Greenham) +
  • complaints about unknown and/or unsupported codecs have been + delayed until they are invoked; this permits applications to open + images and look at tags even if the image data is compressed with + an unknown/unsupported compression scheme +
  • bugs in handling unknown tags have been corrected; applications + that use multiple codecs, each with codec-specific tags, no longer + generate confusing error messages +
  • a missing pseudo-tag definition in the CCITT G3 codec was fixed + (this problem caused core dumps in the tiffcp program) +
  • pseudo-tags are now treated specially; they are always considered + to be set (i.e. they do not use bits in the FIELD_* bit-vectors). +
  • the use of strip chopping can now be controlled on a per-file basis + through a mode parameter supplied when opening a file (``C'' to + enable strip chopping and ``c'' to disable) +
  • two bugs were fixed in the writing of opposite-endian byte-order + files +
  • support was added for three new fax-related tags registered to + SGI: FaxRecvParams, FaxRecvTime, and FaxSubAddress +
  • the bit order of image data read and written can now be controlled + on a per-file basis through a mode parameter supplied when opening + a file (``B'' to force MSB2LSB bit order, ``L'' for LSB2MSB bit + order, and ``H'' for the bit order of the native CPU) +
  • the byte order of image and tag data written to newly-created files + can now be controlled on a per-file basis through a mode parameter + supplied when openening a file (``b'' to force Big-Endian byte order + and ``l'' to force Little-Endian byte order) +
  • the use memory-mapped files for images opened read-only can now + be controlled on a per-file basis through a mode parameter supplied + when opening a file (``M'' to enable use of memory-mapped files + and ``m'' to disable use) +
  • the use of the WIN32 define in tiffiop.h has + been replaced by __WIN32__ +

+

+The ChangeLog will follow, but please note the most important change: +LZW compression has been removed. +

+Unisys has the patent on LZW compression and have been very active in +their enforcement of late, demanding payments of $5000 or more from +websites using unlicensed software to create GIF's. They could well +do the same do persons using libtiff to create LZW compressed TIFF +images. +

+From Burn All GIF's Day: +
+The catch is that it appears to be difficult or impossible to get a +Unisys license to use LZW in free software that complies with the Open +Source Definition +

+Unfortunatly, the removal of LZW compression means that saved image size has +grown dramatically. Without a change in the TIFF spec to support +another lossless compression format, this is unavoidable. +

+The library can use zip for lossless compression, but as this is not +part of the spec, TIFFs using zip compression may not work with other +software +

+We will be making a patch available that will contain the LZW +compression code for users who have either obtained a license from +Unisys or are willing to risk it. +

+LZW decompression is unchanged. +

+

+ +CHANGES IN THE SOFTWARE CONFIGURATION: + +

  • Added TIFFWriteTile.3t man page. + +
  • Added notes on use of makefile.vc in build.html, and fixed + email subscription address. + +

A 16-bit luminance is interpreted + * as a sign bit followed by a 15-bit integer that is converted + * to and from a linear magnitude using the transformation: + * + * L = 2^( (Le+.5)/256 - 64 ) # real from 15-bit + * + * Le = floor( 256*(log2(L) + 64) ) # 15-bit from real + * + * The actual conversion to world luminance units in candelas per sq. meter + * requires an additional multiplier, which is stored in the TIFFTAG_STONITS. + * This value is usually set such that a reasonable exposure comes from + * clamping decoded luminances above 1 to 1 in the displayed image. + * + * The 16-bit values for u and v may be converted to real values by dividing + * each by 32768. (This allows for negative values, which aren't useful as + * far as we know, but are left in case of future improvements in human + * color vision.) + * + * Conversion from (u,v), which is actually the CIE (u',v') system for + * you color scientists, is accomplished by the following transformation: + * + * u = 4*x / (-2*x + 12*y + 3) + * v = 9*y / (-2*x + 12*y + 3) + * + * x = 9*u / (6*u - 16*v + 12) + * y = 4*v / (6*u - 16*v + 12) + * + * This process is greatly simplified by passing 32-bit IEEE floats + * for each of three CIE XYZ coordinates. The codec then takes care + * of conversion to and from LogLuv, though the application is still + * responsible for interpreting the TIFFTAG_STONITS calibration factor. + * + * The information is compressed into one of two basic encodings, depending on + * the setting of the compression tag, which is one of COMPRESSION_SGILOG + * or COMPRESSION_SGILOG24. For COMPRESSION_SGILOG, greyscale data is + * stored as: + * + * 1 15 + * |-+---------------| + * + * COMPRESSION_SGILOG color data is stored as: + * + * 1 15 8 8 + * |-+---------------|--------+--------| + * S Le ue ve + * + * For the 24-bit COMPRESSION_SGILOG24 color format, the data is stored as: + * + * 10 14 + * |----------|--------------| + * Le' Ce + * + * There is no sign bit in the 24-bit case, and the (u,v) chromaticity is + * encoded as an index for optimal color resolution. The 10 log bits are + * defined by the following conversions: + * + * L = 2^((Le'+.5)/64 - 12) # real from 10-bit + * + * Le' = floor( 64*(log2(L) + 12) ) # 10-bit from real + * + * The 10 bits of the smaller format may be converted into the 15 bits of + * the larger format by multiplying by 4 and adding 13314. Obviously, + * a smaller range of magnitudes is covered (about 5 orders of magnitude + * instead of 38), and the lack of a sign bit means that negative luminances + * are not allowed. (Well, they aren't allowed in the real world, either, + * but they are useful for certain types of image processing.) + * + * The desired user format is controlled by the setting the internal + * pseudo tag TIFFTAG_SGILOGDATAFMT to one of: + * SGILOGDATAFMT_FLOAT = IEEE 32-bit float XYZ values + * SGILOGDATAFMT_16BIT = 16-bit integer encodings of logL, u and v + * Raw data i/o is also possible using: + * SGILOGDATAFMT_RAW = 32-bit unsigned integer with encoded pixel + * In addition, the following decoding is provided for ease of display: + * SGILOGDATAFMT_8BIT = 8-bit default RGB gamma-corrected values + * + * For grayscale images, we provide the following data formats: + * SGILOGDATAFMT_FLOAT = IEEE 32-bit float Y values + * SGILOGDATAFMT_16BIT = 16-bit integer w/ encoded luminance + * SGILOGDATAFMT_8BIT = 8-bit gray monitor values + * + * Note that the COMPRESSION_SGILOG applies a simple run-length encoding + * scheme by separating the logL, u and v bytes for each row and applying + * a PackBits type of compression.

is +.I filename +and returns a handle to be used in subsequent calls to routines in +.IR libtiff . +If the open operation fails, then zero is returned. +The +.I mode +parameter specifies if the file is to be opened for reading (``r''), +writing (``w''), or appending (``a'') and, optionally, whether +to override certain default aspects of library operation (see below). +When a file is opened for appending, existing data will not +be touched; instead new data will be written as additional subfiles. +If an existing file is opened for writing, all previous data is +overwritten. +.PP +If a file is opened for reading, the first +.SM TIFF +directory in the file is automatically read +(also see +.IR TIFFSetDirectory (3T) +for reading directories other than the first). +If a file is opened for writing or appending, a default directory +is automatically created for writing subsequent data. +This directory has all the default values specified in +.SM TIFF +Revision 6.0: +.IR BitsPerSample =1, +.IR ThreshHolding "=bilevel art scan," +.IR FillOrder =1 +(most significant bit of each data byte is filled first), +.IR Orientation =1 +(the 0th row represents the visual top of the image, and the 0th +column represents the visual left hand side), +.IR SamplesPerPixel =1, +.IR RowsPerStrip =infinity, +.IR ResolutionUnit =2 +(inches), and +.IR Compression =1 +(no compression). +To alter these values, or to define values for additional fields, +.IR TIFFSetField (3T) +must be used. +.PP +.IR TIFFFdOpen +is like +.IR TIFFOpen +except that it opens a +.SM TIFF +file given an open file descriptor +.IR fd . +The file's name and mode must reflect that of the open descriptor. +The object associated with the file descriptor +.BR "must support random access" . +.PP +.IR TIFFClientOpen +is like +.IR TIFFOpen +except that the caller supplies a collection of functions that the +library will use to do \s-1UNIX\s+1-like I/O operations. +The +.I readproc +and +.I writeproc +are called to read and write data at the current file position. +.I seekproc +is called to change the current file position a la +.IR lseek (2). +.I closeproc +is invoked to release any resources associated with an open file. +.I sizeproc +is invoked to obtain the size in bytes of a file. +.I mapproc +and +.I unmapproc +are called to map and unmap a file's contents in memory; c.f. +.IR mmap (2) +and +.IR munmap (2). +The +.I clientdata +parameter is an opaque ``handle'' passed to the client-specified +routines passed as parameters to +.IR TIFFClientOpen . +.SH OPTIONS +The open mode parameter can include the following flags in +addition to the ``r'', ``w'', and ``a'' flags. +Note however that option flags must follow the read-write-append +specification. +.TP +.B l +When creating a new file force information be written with +Little-Endian byte order (but see below). +By default the library will create new files using the native +.SM CPU +byte order. +.TP +.B b +When creating a new file force information be written with +Big-Endian byte order (but see below). +By default the library will create new files using the native +.SM CPU +byte order. +.TP +.B L +Force image data that is read or written to be treated with +bits filled from Least Significant Bit (\s-1LSB\s+1) to +Most Significant Bit (\s-1MSB\s+1). +Note that this is the opposite to the way the library has +worked from its inception. +.TP +.B B +Force image data that is read or written to be treated with +bits filled from Most Significant Bit (\s-1MSB\s+1) to +Least Significant Bit (\s-1LSB\s+1); this is the default. +.TP +.B H +Force image data that is read or written to be treated with +bits filled in the same order as the native +.SM CPU. +.TP +.B M +Enable the use of memory-mapped files for images opened read-only. +If the underlying system does not support memory-mapped files +or if the specific image being opened cannot be memory-mapped +then the library will fallback to using the normal system interface +for reading information. +By default the library will attempt to use memory-mapped files. +.TP +.B m +Disable the use of memory-mapped files. +.TP +.B C +Enable the use of ``strip chopping'' when reading images +that are comprised of a single strip or tile of uncompressed data. +Strip chopping is a mechanism by which the library will automatically +convert the single-strip image to multiple strips, +each of which has about 8 Kilobytes of data. +This facility can be useful in reducing the amount of memory used +to read an image because the library normally reads each strip +in its entirety. +Strip chopping does however alter the apparent contents of the +image because when an image is divided into multiple strips it +looks as though the underlying file contains multiple separate +strips. +Finally, note that default handling of strip chopping is a compile-time +configuration parameter. +The default behaviour, for backwards compatibility, is to enable +strip chopping. +.TP +.B c +Disable the use of strip chopping when reading images. +.SH "BYTE ORDER" +The +.SM TIFF +specification (\fBall versions\fP) states that compliant readers +.IR "must be capable of reading images written in either byte order" . +Nonetheless some software that claims to support the reading of +.SM TIFF +images is incapable of reading images in anything but the native +.SM CPU +byte order on which the software was written. +(Especially notorious +are applications written to run on Intel-based machines.) +By default the library will create new files with the native +byte-order of the +.SM CPU +on which the application is run. +This ensures optimal performance and is portable to any application +that conforms to the TIFF specification. +To force the library to use a specific byte-order when creating +a new file the ``b'' and ``l'' option flags may be included in +the call to open a file; for example, ``wb'' or ``wl''. +.SH "RETURN VALUES" +Upon successful completion +.IR TIFFOpen , +.IR TIFFFdOpen , +and +.IR TIFFClientOpen +return a +.SM TIFF +pointer. +Otherwise, NULL is returned. +.SH DIAGNOSTICS +All error messages are directed to the +.IR

+The routines described here provide a high-level interface +through which +.SM TIFF +images may be read into memory. +Images may be strip- or tile-based and have a variety of different +characteristics: bits/sample, samples/pixel, photometric, etc. +Decoding state is encapsulated in a +.I TIFFRGBAImage +structure making it possible to capture state for multiple images +and quickly switch between them. +The target raster format can be customized to a particular application's +needs by installing custom routines that manipulate image data +according to application requirements. +.PP +The default usage for these routines is: check if an image can +be processed using +.IR TIFFRGBAImageOK , +construct a decoder state block using +.IR TIFFRGBAImageBegin , +read and decode an image into a target raster using +.IR TIFFRGBAImageGet , +and then +release resources using +.IR TIFFRGBAImageEnd . +.I TIFFRGBAImageGet +can be called multiple times to decode an image using different +state parameters. +If multiple images are to be displayed and there is not enough +space for each of the decoded rasters, multiple state blocks can +be managed and then calls can be made to +.I TIFFRGBAImageGet +as needed to display an image. +.PP +The generated raster is assumed to be an array of +.I width +times +.I height +32-bit entries, where +.I width +must be less than or equal to the width of the image (\c +.I height +may be any non-zero size). +If the raster dimensions are smaller than the image, the image data +is cropped to the raster bounds. +If the raster height is greater than that of the image, then the +image data are placed in the lower part of the raster. +(Note that the raster is assume to be organized such that the pixel +at location (\fIx\fP,\fIy\fP) is \fIraster\fP[\fIy\fP*\fIwidth\fP+\fIx\fP]; +with the raster origin in the lower-left hand corner.) +.PP +Raster pixels are 8-bit packed red, green, blue, alpha samples. +The macros +.IR TIFFGetR , +.IR TIFFGetG , +.IR TIFFGetB , +and +.I TIFFGetA +should be used to access individual samples. +Images without Associated Alpha matting information have a constant +Alpha of 1.0 (255). +.PP +.I TIFFRGBAImageGet +converts non-8-bit images by scaling sample values. +Palette, grayscale, bilevel, +.SM CMYK\c +, and YCbCr images are converted to +.SM RGB +transparently. +Raster pixels are returned uncorrected by any colorimetry information +present in the directory. +.PP +The paramater +.I stopOnError +specifies how to act if an error is encountered while reading +the image. +If +.I stopOnError +is non-zero, then an error will terminate the operation; otherwise +.I TIFFRGBAImageGet +will continue processing data until all the possible data in the +image have been requested. +.SH "ALTERNATE RASTER FORMATS" +To use the core support for reading and processing +.SM TIFF +images, but write the resulting raster data in a different format +one need only override the ``\fIput methods\fP'' used to store raster data. +These methods are are defined in the +.I TIFFRGBAImage +structure and initially setup by +.I TIFFRGBAImageBegin +to point to routines that pack raster data in the default +.SM ABGR +pixel format. +Two different routines are used according to the physical organization +of the image data in the file: +.IR PlanarConfiguration =1 +(packed samples), +and +.IR PlanarConfiguration =2 +(separated samples). +Note that this mechanism can be used to transform the data before +storing it in the raster. +For example one can convert data +to colormap indices for display on a colormap display. +.SH "SIMULTANEOUS RASTER STORE AND DISPLAY" +It is simple to display an image as it is being read into memory +by overriding the put methods as described above for supporting +alternate raster formats. +Simply keep a reference to the default put methods setup by +.I TIFFRGBAImageBegin +and then invoke them before or after each display operation. +For example, the +.IR tiffgt (1) +utility uses the following put method to update the display as +the raster is being filled: +.sp +.nf +.ft C +static void +putContigAndDraw(TIFFRGBAImage* img, uint32* raster, + uint32 x, uint32 y, uint32 w, uint32 h, + int32 fromskew, int32 toskew, + unsigned char* cp) +{ + (*putContig)(img, raster, x, y, w, h, fromskew, toskew, cp); + if (x+w == width) { + w = width; + if (img->orientation == ORIENTATION_TOPLEFT) + lrectwrite(0, y-(h-1), w-1, y, raster-x-(h-1)*w); + else + lrectwrite(0, y, w-1, y+h-1, raster); + } +} +.ft R +.fi +.sp +(the original routine provided by the library is saved in the +variable +.IR putContig .) +.SH "SUPPORTING ADDITIONAL TIFF FORMATS" +The +.I TIFFRGBAImage +routines support the most commonly encountered flavors of +.SM TIFF. +It is possible to extend this support by overriding the ``\fIget method\fP'' +invoked by +.I TIFFRGBAImageGet +to read +.SM TIFF +image data. +Details of doing this are a bit involved, it is best to make a copy +of an existing get method and modify it to suit the needs of an +application. +.SH NOTES +Samples must be either 1, 2, 4, 8, or 16 bits. +Colorimetric samples/pixel must be either 1, 3, or 4 (i.e. +.I SamplesPerPixel +minus +.IR ExtraSamples ). +.PP +Palettte image colormaps that appear to be incorrectly written +as 8-bit values are automatically scaled to 16-bits. +.SH "RETURN VALUES"

TIFFWriteScanline(TIFF* tif, tdata_t buf, uint32 row, tsample_t sample)" +.SH DESCRIPTION +Write data to a file at the specified row. +The +.I sample +parameter is used only if data are organized in separate planes (\c +.IR PlanarConfiguration =2). +The data are assumed to be uncompressed and in the native +bit- and byte-order of the host machine. +The data written to the file is +compressed according to the compression scheme +of the current +.SM TIFF +directory (see further below). +If the current scanline is past the end of the current subfile, the +.I ImageLength +field is automatically increased to include the scanline (except +for +.IR PlanarConfiguration =2, +where the +.I ImageLength +cannot be changed once the first data are written). +If the +.I ImageLength +is increased, the +.I StripOffsets +and +.I StripByteCounts +fields are similarly enlarged to reflect data written past the +previous end of image. +.SH NOTES +The library writes encoded data using the native machine byte order. +Correctly implemented +.SM TIFF +readers are expected to do any necessary byte-swapping to +correctly process image data with BitsPerSample greater than 8. +The library attempts to hide bit-ordering differences +between the image and the native machine by converting data +from the native machine order. +.PP +In C++ the +.I sample +parameter defaults to 0. +.PP +Once data are written to a file for the current directory, +the values of certain tags may not be altered; see +.IR TIFFSetField (3T) +for more information. +.PP +It is not possible to write scanlines to a file that +uses a tiled organization. The routine +.IR TIFFIsTiled +can be used to determine if the file is organized +as tiles or strips. +.SH "RETURN VALUES" +.IR TIFFWriteScanline +returns \-1 if it immediately detects an error +and 1 for a successful write. +.SH DIAGNOSTICS +All error messages are directed to the +.IR TIFFError (3T) +routine. +.PP +.BR "%s: File not open for writing . +The file was opened for reading, not writing. +.PP +.BR "Can not write scanlines to a tiled image" . +An attempt was made to write a scanline to a tiled image. +The image is assumed to be organized in tiles because the +.I TileWidth +and +.I TileLength +tags have been set with +.IR TIFFSetField (3T). +.PP +.BR "Compression algorithm does not support random access" . +Data was written in a non-sequential order to a file that +uses a compression algorithm and that has +.I RowsPerStrip +greater than one. +That is, data in the image is to be stored in a compressed form, +and with multiple rows packed into a strip. +In this case, the library does not support random access to the data. +The data should either be written as entire strips, +sequentially by rows, or the value of +.I RowsPerStrip +should be set to one. +.PP +\fB%s: Must set "ImageWidth" before writing data\fP. +The image's width has not be set before the first write. +See +.IR TIFFSetField (3T) +for information on how to do this. +.PP +\fB%s: Must set "PlanarConfiguration" before writing data\fP. +The organization of data has not be defined before the first write. +See +.IR TIFFSetField (3T) +for information on how to do this. +.PP +\fBCan not change "ImageLength" when using separate planes\fP. +Separate image planes are being used (\c +.IR PlanarConfiguration =2), +but the number of rows has not been specified before the first write. +The library supports the dynamic growth of an image only when data +are organized in a contiguous manner (\c +.IR PlanarConfiguration =1). +.PP +.BR "%d: Sample out of range, max %d" . +The +.I sample +parameter was greater than the value of the SamplesPerPixel tag. +.PP +.BR "%s: No space for strip arrays . +There was not enough space for the arrays that hold strip +offsets and byte counts. +.SH BUGS +Writing subsampled YCbCR data does not work correctly +because, for +.IR PlanarConfiguration =2 +the size of a scanline is not calculated on a per-sample basis, +and for +.IR PlanarConfiguration
