The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that the +`configure' script does not know about. Run `./configure --help' for +details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + +You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + +Installation Names +================== + +By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + +Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + +There may be some features `configure' cannot figure out automatically, +but needs to determine by the type of machine the package will run on. +Usually, assuming the package is built to be run on the _same_ +architectures, `configure' can figure that out, but if it prints a +message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, you +can create a site shell script called `config.site' that gives default +values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + +Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + +`configure' recognizes the following options to control how it operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..23a12ff --- /dev/null +++ b/Makefile.am @@ -0,0 +1,32 @@ +SUBDIRS = lib util doc pic +WINDOWS = $(top_srcdir)/windows/GifWin.cpp \ + $(top_srcdir)/windows/GifWin.h \ + $(top_srcdir)/windows/StdAfx.h \ + $(top_srcdir)/windows/gifshow.cpp \ + $(top_srcdir)/windows/gifshow.dsp \ + $(top_srcdir)/windows/gifshow.dsw \ + $(top_srcdir)/windows/gifshow.h \ + $(top_srcdir)/windows/gifshow.ico \ + $(top_srcdir)/windows/gifshow.rc \ + $(top_srcdir)/windows/libungif.dsp \ + $(top_srcdir)/windows/resource.h + +GAMEBOYADVANCE = $(top_srcdir)/gba/giftest.c \ + $(top_srcdir)/gba/giftest.dsp \ + $(top_srcdir)/gba/giftest.mak \ + $(top_srcdir)/gba/res/cover.gif \ + $(top_srcdir)/gba/res/porsche-240x160.gif \ + $(top_srcdir)/gba/res/x-trans.gif + +EXTRA_DIST = Makefile.unx \ + ONEWS \ + autogen.sh \ + giflib.spec \ + test-unx \ + giflib.lsm \ + TODO \ + BUGS \ + DEVELOPERS \ + $(WINDOWS) \ + $(GAMEBOYADVANCE) +#TESTS=test-unx diff --git a/Makefile.in b/Makefile.in new file mode 100644 index 0000000..5d17378 --- /dev/null +++ b/Makefile.in @@ -0,0 +1,675 @@ +# Makefile.in generated by automake 1.10 from Makefile.am. +# @configure_input@ + +# Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, +# 2003, 2004, 2005, 2006 Free Software Foundation, Inc. +# This Makefile.in is free software;

All users are strongly encouraged to upgrade. + +Code Fixes +---------- +* Fix segfault in utilities due to referencing ColorMaps in GifFiles that had + no ColorMap present. +* Fix gif2x11 to work on 24 bit displays. +* Fix for giftext segfault when the GifFile does not store a global colormap. +* Checks to fail gracefully when an image contains improper LZ codes. +* Close file handles on failure in DGifOpenFileHandle() +* Checks to operate on files in binary mode on WIN32 as well as MSDOS. + +Building +-------- +* Add checks to make building on Win32 easier. +* Allow turning off gl_s, rle, and X11 support from the configure command line. +* Fix for finding a 32 bit integer type on some platforms. +* Only enable -Wall if we're using gcc. + +Version 4.1.4 +============= +This version fixes some bugs with deallocating ColorMaps.

Note -- there has been one API changing event for + Windows (renaming DrawText to DrawGifText.) This should have conflicted with + Windows API and therefore caused the builds to fail previously.

A recompile of your dependent code + will be necessary in this case. + +Version 4.1.3 +============= +This version fixes some bugs in the Extension writing code in +EGifPutExtensionFirst, Next, and Last. Using these functions, it is possible +to output extensions that contain multiple subblocks. Additionally, library +code has been updated to use these functions, making it safe to output +long Comments, and multi-block extensions read in from another file. + +* giflib is now hosted on sourceforge with libungif: + http://sourceforge.net/projects/libungif +* Make the EGifPutExtension{First,Next,Last} family of functions use WRITE + so user defined WRITE methods will output them correctly. +* Modify EGifSpew and EGifPutComment to use EGifPutExtension{First,Next,Last} + so we won't output broken GIFs when dealing with GIFs with multiple + subblocks. +* More -Wall fixes revealed while testing on Solaris and FreeBSD. +* Updated the gif_lib.html documentation to not use EGifPutExtension when + dealing with multiple subblocks.

This is actually the major motivating factor behind + libungif; to provide third-party distributors a means to provide a gif + library without the patented LZW encoder. + + * A new configure script to make compilation of the library on multiple + platforms easier.

It's not clear, however, that anyone ever has or + ever will use this feature for anything... + +New Tools and Options + +4. A brand new, ultra-spiffy tool `icon2gif' is included.

It can also dump most + GIFs in the same text-only form it parses. This makes it easy to edit GIFs + even if you don't have a graphics editor. + +5. The gifclip utility supports a new `-c' (complement) option that allows you + to perform an `inverse clip', removing horizontal or vertical bands from an + image. + +6. The gifclrmp utility supports a new `-t' switch for shuffling color index + values. + +7. A new tool `gifcolor' generates test pattern from colormap input. + +New Documentation and Examples + +8.

Two source code files gifspnge.c and giffiltr.c have been added to the + util directory. These are GIF copiers that exercise the I/O routines, + provided as skeletons for your applications.

Don't know how much stuff I want to sync into this, +though, as I keep hoping gif's will take their last gasp and die. (Why do we +need gif now that we have png and mng?) + +====== + +Besides fixing bugs, what's really needed is for someone to work out how to +calculate a colormap for writing gifs from rgb sources. Right now, an rgb +source that has only two colors (b/w) is being converted into an 8 bit gif.... +Which is horrendously wasteful without compression. + +Any volunteers? + +======= +The Present Extension code is pretty hacky. It looks like giflib's ability to +do Extension code was added on at a later time and also was not implemented +entirely in conformance with the gif89a spec. I've hacked it further to make +it conform to the spec, but it would benefit greatly from a complete rewrite. + +If there is ever a version-5.0 of this library (with API level changes), this +should definitely be one of the areas that gets worked on. + +======= +Documentation needs updating to reflect additions to the API. This would best +be done with auto-extraction from the SOURCES.... + +======= +[UPDATE at bottom] +Here's a change to the library code that has been proposed: Pulling known +extensions (comment blocks, etc) out of the Extensions array and putting them +in actual places within the GifType structure so application programmers don't +have to search through the Extension array for them. + +I'm not sure how I want to implemement this yet -- Actually removing them from +the extension array would break the API compatibility with libungif. Making +copies would waste resources needlessly. Making convenience links with the +idea of deprecating the access of the extension block directly for standard +features would be okay, but creates extra work in the long run -- really we +need to put the convenience links into the current Extension array. + +We have to decide where in the structure each extension belongs, generalize +the AddExtensionBlock function to be able to add the extensionblock to any +area of the structure, rework the gif writing code to place the structures +where they belong, rework the code writing to the Extension Array so that it +can handle links as well as blocks. + +And on the other hand, it could turn out that putting extensions into the main +structure is not intuitive to everyone. Extensions are "extensions" and +people may want to look for them grouped together.... I suppose this could +either mean leaving everything in the extension array, or creating a new +extension field that has the extensions dangling off of it (comment, gifanim +stuff, unknown, etc.) This is okay except that it'd be best to have real +copies of the extension in the fields instead of links (so that we could make +arrays rather than arrays of pointers.) + +[UPDATE:1998 3 Dec] +After reading through the gif89a specification, I'm not sure this is all that +great. It seems that each image in a gif stream needs to have separate +extension blocks. This means that an animated gif will have a Graphics +Extension Block for each Image in the animation.

gif2bgi

+ +A program to display images saved as GIF files on IBM PC display devices using +the BGI (Borland) driver interface.

+ +The program operates as follows:

+ +

    +
  1. +Reads the GIF file header and determines the image size.

    + +

  2. +Dynamically allocates enough memory to hold all the image internally. +One byte per pixel is always allocated, so a little bit more than +width*height (of screen, not image) bytes are required.

    + +

  3. +Reads all the image in. Interlaced images are read in correctly, although +they are displayed sequentially.

    + +

  4. +Display first image using the defaults as set by the command line option.

    + +

  5. +Goes to interactive mode. For a full description of the interactive mode +see below.

    +

+ +

Usage:

+ +
+gif2bgi [-q] [-d BGI dir] [-u driver] [-z zoom] [-b] [-h] gif-file
+
+ +If no GIF is given, gif2bgi will try to read a GIF file from stdin.

+ +

Memory required:

+ +Screen. + +

Options:

+
+
[-q] +
Quiet mode. Default off on MSDOS, on under UNIX. Controls printout + of running scan lines. Use -q- to invert.

+ +

[-d BGI Directory] +
Where we should look for default drivers (as supplied by Borland). + For example '-d c:/tc/bgi'.

+ +

[-u driver] +
Specifies a user-defined BGI driver. If for example + you have a BGI driver for your special vga called MYVGA.BGI and you want + to run it in mode 2, then type '-u c:/tc/bgi/myvga.2'. Note the absolute + path to the driver must be specified. Also note that we use '/' and not + '\' so they won't be treated as options.

+ +

[-z zoom] +
Sets zoom factor of the view. Zoom factor should be + power of 2 up to 256. Default is 1 (no zoom).

+ +

[-h] +
Print one line of command-line help, similar to Usage above.

+

+ +

Interactive mode:

+ +Once the image is displayed, the gif2bgi program goes into interactive mode +which recognizes the following commands:

+ +

+
C - get Color and position +
In this submenu, a cursor appears and the location and color of the + pixel underneath it are printed. The 4 arrows may be used (shifted for + faster movement) to move the cursor. Any other key will abort this submode.

+ +

D - zoom Down +
Zoom down by factor of 2 unless current zoom factor is 1.

+ +

R - Redraw +
Redraw the image.

+ +

S - print Status +
Print status of image and program.

+ +

U - zoom Up +
Zoom up by factor of 2 unless current zoom factor is 256.

+ +

arrow keys +
The 4 arrow keys can be used to pan in the desired direction, if the image + overflows in that direction. If the image fits into the screen, arrow + keys are ignored. The panning steps are 1/2 screen if not on image end.

+ +

SPC - abort +
Space bar may be used to abort current image drawing.

+ +

ESC - abort +
Escape may be used to abort current image drawing. +
+ + +

Notes:

+ +This program is useless in a Unix environment and is not normally +built there.

+ +No color quantization is used in this program; thus, if a GIF image has more +colors than the BGI driver support, this program will abort.

+ +This driver is optimized for drivers with one byte per pixel (256 colors) +and will run MUCH faster on such drivers.

+ +

Bugs:

+ +For some reason I could not figure out, on my ATI wonder card, int 10h call +10h (AH = AL = 10h) to set the color registers sometimes result with wrong +colors. Direct access of the card registers gives correct results.

gif2epsn

+ +A program to dump images saved as GIF files on Epson type printers.

+ +

Usage:

+ +
+gif2epsn [-q] [-d dither] [-t bw] [-m map] [-i] [-n] [-p printer] [-h] gif-file
+
+ +If no gif-file is given, Gif2Epsn will try to read a GIF file from stdin.

+ + +

Memory required:

+ +Screen. + +

Options:

+ +
+
[-q] +
Quiet mode. Default off on MSDOS, on under UNIX. Controls printout + of running scan lines. Use -q- to invert.

+ +

[-d dither] +
Sets size of dithering matrix, where DitherSize can be + 2,3 or 4 only (for 2x2, 3x3 and 4x4 dithering matrices). Default is 2. + Note image will be displayed in this mode only if the mapping + option (see -m) selected this mode.

+ +

[-t bw] +
Sets threshold level for B&W mapping in percent. + This threshold level is used in the different mappings as selected via -m. + Default is 19%.

+ +

[-m map] +
Select method to map colors to B&W. Mapping can be: + +
+
0
+ Every none background color is considered foreground (white color but + is drawn as black by printer, unless -i is specified).

+ +

1
+ If 0.3 * RED + 0.59 * GREEN + 0.11 * YELLOW > BW the pixel is + considered white color.

+ +

2
+ Colors are mapped as in 1, and use dithering of size as defined using + -d option. BWthreshold is used here as scaler.

+

+ +The default is option 0.

+ +

[-i] +
Invert the image, i.e. black -> white, white -> black.

+ +

[-n] +
Nicer image. Uses double-density feature of Epson printer. This + takes more time (and kills your ink cartridge faster...) but results + are usually better.

+ +

[-p printer] +
Under Unix, output goes to stdout by default; under DOS, the + default is LPT1:. With this switch you can specify the output + target.

+ +

[-h] +
print one line of command line help, similar to Usage above.

+

+ +

Notes:

+ +The output has an aspect ratio of 1, so a square image will be square in +hardcopy as well.

+ +The widest image can be printed is 640 pixels, on 8 inch paper. You +probably will need to flip wider images, if height is less than that: +`gifflip -r x29.gif | gif2epsn'. Wider +images will be clipped.

+ +If no gif-file is given, Gif2X11 will try to read a GIF file from stdin. +Note: this program does not read the X resource data base.

+ +

Memory required:

+ +Screen. + +

Options:

+ +
+
[-q] +
Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout + of running scan lines. Use -q- to invert.

+ +

[-p PosX PosY] +
Set the position of image on screen. By default the + program will prompt for position.

+ +

[-d Display] +
What X server should be connected to.

+ +

[-f] +
Force attempt to allocate exact colors. This usually will result in a + very muddled image if not enough colors can be allocated; the rest of + them will be approximated by the closest one. By default the least bits + of the colors are stripped until success (in allocation) which looks much + better.

+ +

[-h] +
Print one line command line help, similar to Usage above.

As the specification says, they may appear at anytime. There + is not a requirement to send a clear code when the string table is full. + + It is the encoder's decision as to when the table should be cleared. When + the table is full, the encoder can chose to use the table as is, making no + changes to it until the encoder chooses to clear it. The encoder during + this time sends out codes that are of the maximum Code Size. + + As we can see from the above, when the decoder's table is full, it must + not change the table until a clear code is received. The Code Size is that + of the maximum Code Size. Processing other than this is done normally. + + Because of a large base of decoders that do not handle the decompression in + this manner, we ask developers of GIF encoding software to NOT implement + this feature until at least January 1991 and later if they see that their + particular market is not ready for it. This will give developers of GIF + decoding software time to implement this feature and to get it into the + hands of their clients before the decoders start "breaking" on the new + GIF's. It is not required that encoders change their software to take + advantage of the deferred clear code, but it is for decoders. + + APPLICATION EXTENSION BLOCK - APPLICATION IDENTIFIER + + There will be a Courtesy Directory file located on CompuServe in the PICS + forum.

This service is offered free of charge; please provide us with your +mailing address. + + +4. About the Document. + +This document describes in detail the definition of the Graphics Interchange +Format. This document is intended as a programming reference; it is +recommended that the entire document be read carefully before programming, +because of the interdependence of the various parts. There is an individual +section for each of the Format blocks. Within each section, the sub-section +labeled Required Version refers to the version number that an encoder will have +to use if the corresponding block is used in the Data Stream. Within each +section, a diagram describes the individual fields in the block; the diagrams +are drawn vertically; top bytes in the diagram appear first in the Data Stream. +Bits within a byte are drawn most significant on the left end. Multi-byte +numeric fields are ordered Least Significant Byte first. Numeric constants are +represented as Hexadecimal numbers, preceded by "0x". Bit fields within a byte +are described in order from most significant bits to least significant bits. + + +5. General Description. + +The Graphics Interchange Format(sm) defines a protocol intended for the on-line +transmission and interchange of raster graphic data in a way that is +independent of the hardware used in their creation or display. + +The Graphics Interchange Format is defined in terms of blocks and sub-blocks +which contain relevant parameters and data used in the reproduction of a +graphic. A GIF Data Stream is a sequence of protocol blocks and sub-blocks +representing a collection of graphics. In general, the graphics in a Data +Stream are assumed to be related to some degree, and to share some control +information; it is recommended that encoders attempt to group together related +graphics in order to minimize hardware changes during processing and to +minimize control information overhead. For the same reason, unrelated graphics +or graphics which require resetting hardware parameters should be encoded +separately to the extent possible. + +A Data Stream may originate locally, as when read from a file, or it may +originate remotely, as when transmitted over a data communications line. The +Format is defined with the assumption that an error-free Transport Level +Protocol is used for communications; the Format makes no provisions for +error-detection and error-correction. + +The GIF Data Stream must be interpreted in context, that is, the application +program must rely on information external to the Data Stream to invoke the +decoder process. + + +6. Version Numbers. + +The version number in the Header of a Data Stream is intended to identify the +minimum set of capabilities required of a decoder in order to fully process the +Data Stream. An encoder should use the earliest possible version number that +includes all the blocks used in the Data Stream. Within each block section in +this document, there is an entry labeled Required Version which specifies the + + + + + + + + 3 + + +earliest version number that includes the corresponding block. The encoder +should make every attempt to use the earliest version number covering all the +blocks in the Data Stream; the unnecessary use of later version numbers will +hinder processing by some decoders. + + +7. The Encoder. + +The Encoder is the program used to create a GIF Data Stream. From raster data +and other information, the encoder produces the necessary control and data +blocks needed for reproducing the original graphics. + +The encoder has the following primary responsibilities. + + - Include in the Data Stream all the necessary information to + reproduce the graphics. + + - Insure that a Data Stream is labeled with the earliest possible + Version Number that will cover the definition of all the blocks in + it; this is to ensure that the largest number of decoders can + process the Data Stream. + + - Ensure encoding of the graphics in such a way that the decoding + process is optimized. Avoid redundant information as much as + possible. + + - To the extent possible, avoid grouping graphics which might + require resetting hardware parameters during the decoding process. + + - Set to zero (off) each of the bits of each and every field + designated as reserved. Note that some fields in the Logical Screen + Descriptor and the Image Descriptor were reserved under Version + 87a, but are used under version 89a. + + +8. The Decoder. + +The Decoder is the program used to process a GIF Data Stream. It processes the +Data Stream sequentially, parsing the various blocks and sub-blocks, using the +control information to set hardware and process parameters and interpreting the +data to render the graphics. + +The decoder has the following primary responsibilities. + + - Process each graphic in the Data Stream in sequence, without + delays other than those specified in the control information. + + - Set its hardware parameters to fit, as closely as possible, the + control information contained in the Data Stream. + + +9. Compliance. + +An encoder or a decoder is said to comply with a given version of the Graphics +Interchange Format if and only if it fully conforms with and correctly +implements the definition of the standard associated with that version. An + + + + + + + + 4 + + +encoder or a decoder may be compliant with a given version number and not +compliant with some subsequent version. + + +10. About Recommendations. + +Each block section in this document contains an entry labeled Recommendation; +this section lists a set of recommendations intended to guide and organize the +use of the particular blocks. Such recommendations are geared towards making +the functions of encoders and decoders more efficient, as well as making +optimal use of the communications bandwidth. It is advised that these +recommendations be followed. + + +11. About Color Tables. + +The GIF format utilizes color tables to render raster-based graphics. A color +table can have one of two different scopes: global or local. A Global Color +Table is used by all those graphics in the Data Stream which do not have a +Local Color Table associated with them. The scope of the Global Color Table is +the entire Data Stream. A Local Color Table is always associated with the +graphic that immediately follows it; the scope of a Local Color Table is +limited to that single graphic. A Local Color Table supersedes a Global Color +Table, that is, if a Data Stream contains a Global Color Table, and an image +has a Local Color Table associated with it, the decoder must save the Global +Color Table, use the Local Color Table to render the image, and then restore +the Global Color Table. Both types of color tables are optional, making it +possible for a Data Stream to contain numerous graphics without a color table +at all. For this reason, it is recommended that the decoder save the last +Global Color Table used until another Global Color Table is encountered. In +this way, a Data Stream which does not contain either a Global Color Table or +a Local Color Table may be processed using the last Global Color Table saved. +If a Global Color Table from a previous Stream is used, that table becomes the +Global Color Table of the present Stream. This is intended to reduce the +overhead incurred by color tables. In particular, it is recommended that an +encoder use only one Global Color Table if all the images in related Data +Streams can be rendered with the same table. If no color table is available at +all, the decoder is free to use a system color table or a table of its own. In +that case, the decoder may use a color table with as many colors as its +hardware is able to support; it is recommended that such a table have black and +white as its first two entries, so that monochrome images can be rendered +adequately. + +The Definition of the GIF Format allows for a Data Stream to contain only the +Header, the Logical Screen Descriptor, a Global Color Table and the GIF +Trailer. Such a Data Stream would be used to load a decoder with a Global Color +Table, in preparation for subsequent Data Streams without a color table at all. + + +12. Blocks, Extensions and Scope. + +Blocks can be classified into three groups : Control, Graphic-Rendering and +Special Purpose. Control blocks, such as the Header, the Logical Screen +Descriptor, the Graphic Control Extension and the Trailer, contain information +used to control the process of the Data Stream or information used in setting +hardware parameters. Graphic-Rendering blocks such as the Image Descriptor and + + + + + + + + 5 + + +the Plain Text Extension contain information and data used to render a graphic +on the display device. Special Purpose blocks such as the Comment Extension and +the Application Extension are neither used to control the process of the Data +Stream nor do they contain information or data used to render a graphic on the +display device. With the exception of the Logical Screen Descriptor and the +Global Color Table, whose scope is the entire Data Stream, all other Control +blocks have a limited scope, restricted to the Graphic-Rendering block that +follows them. Special Purpose blocks do not delimit the scope of any Control +blocks; Special Purpose blocks are transparent to the decoding process. +Graphic-Rendering blocks and extensions are used as scope delimiters for +Control blocks and extensions. The labels used to identify labeled blocks fall +into three ranges : 0x00-0x7F (0-127) are the Graphic Rendering blocks, +excluding the Trailer (0x3B); 0x80-0xF9 (128-249) are the Control blocks; +0xFA-0xFF (250-255) are the Special Purpose blocks. These ranges are defined so +that decoders can handle block scope by appropriately identifying block labels, +even when the block itself cannot be processed. + + +13. Block Sizes. + +The Block Size field in a block, counts the number of bytes remaining in the +block, not counting the Block Size field itself, and not counting the Block +Terminator, if one is to follow. Blocks other than Data Blocks are intended to +be of fixed length; the Block Size field is provided in order to facilitate +skipping them, not to allow their size to change in the future. Data blocks +and sub-blocks are of variable length to accommodate the amount of data. + + +14. Using GIF as an embedded protocol. + +As an embedded protocol, GIF may be part of larger application protocols, +within which GIF is used to render graphics. In such a case, the application +protocol could define a block within which the GIF Data Stream would be +contained. The application program would then invoke a GIF decoder upon +encountering a block of type GIF. This approach is recommended in favor of +using Application Extensions, which become overhead for all other applications +that do not process them. Because a GIF Data Stream must be processed in +context, the application must rely on some means of identifying the GIF Data +Stream outside of the Stream itself. + + +15. Data Sub-blocks. + + a. Description. Data Sub-blocks are units containing data. They do not + have a label, these blocks are processed in the context of control + blocks, wherever data blocks are specified in the format. The first byte + of the Data sub-block indicates the number of data bytes to follow. A + data sub-block may contain from 0 to 255 data bytes. The size of the + block does not account for the size byte itself, therefore, the empty + sub-block is one whose size field contains 0x00. + + b.

It does not have a scope of itself. + + e. Recommendation. None. + + +16. Block Terminator. + + a. Description. This zero-length Data Sub-block is used to terminate a + sequence of Data Sub-blocks. It contains a single byte in the position of + the Block Size field and does not contain data. + + b. Required Version. 87a. + + c.

Extensions and Scope. This block terminates the immediately preceding + sequence of Data Sub-blocks. This block cannot be modified by any + extension. + + e. Recommendation. None. + + +17. Header. + + a. Description. The Header identifies the GIF Data Stream in context. The + Signature field marks the beginning of the Data Stream, and the Version + field identifies the set of capabilities required of a decoder to fully + process the Data Stream. This block is REQUIRED; exactly one Header must + be present per Data Stream. + + b. Required Version. Not applicable. This block is not subject to a + version number. This block must appear at the beginning of every Data + Stream. + + c.

The scope of this block is the entire + Data Stream. This block cannot be modified by any extension. + + + + + + + + + + + 8 + + + d. Recommendations. + + i) Signature - This field identifies the beginning of the GIF Data + Stream; it is not intended to provide a unique signature for the + identification of the data. It is recommended that the GIF Data + Stream be identified externally by the application. (Refer to + Appendix G for on-line identification of the GIF Data Stream.) + + ii) Version - ENCODER : An encoder should use the earliest possible + version number that defines all the blocks used in the Data Stream. + When two or more Data Streams are combined, the latest of the + individual version numbers should be used for the resulting Data + Stream. DECODER : A decoder should attempt to process the data + stream to the best of its ability; if it encounters a version + number which it is not capable of processing fully, it should + nevertheless, attempt to process the data stream to the best of its + ability, perhaps after warning the user that the data may be + incomplete. + + +18. Logical Screen Descriptor. + + a. Description. The Logical Screen Descriptor contains the parameters + necessary to define the area of the display device within which the + images will be rendered. The coordinates in this block are given with + respect to the top-left corner of the virtual screen; they do not + necessarily refer to absolute coordinates on the display device. This + implies that they could refer to window coordinates in a window-based + environment or printer coordinates when a printer is used. + + This block is REQUIRED; exactly one Logical Screen Descriptor must be + present per Data Stream. + + b. Required Version. Not applicable. This block is not subject to a + version number. This block must appear immediately after the Header. + + c. Syntax. + + 7 6 5 4 3 2 1 0 Field Name Type + +---------------+ + 0 | | Logical Screen Width Unsigned + +- -+ + 1 | | + +---------------+ + 2 | | Logical Screen Height Unsigned + +- -+ + 3 | | + +---------------+ + 4 | | | | | See below + +---------------+ + 5 | | Background Color Index Byte + +---------------+ + 6 | | Pixel Aspect Ratio Byte + +---------------+ + + + + + + + + + + 9 + + + = Global Color Table Flag 1 Bit + Color Resolution 3 Bits + Sort Flag 1 Bit + Size of Global Color Table 3 Bits + + i) Logical Screen Width - Width, in pixels, of the Logical Screen + where the images will be rendered in the displaying device. + + ii) Logical Screen Height - Height, in pixels, of the Logical + Screen where the images will be rendered in the displaying device. + + iii) Global Color Table Flag - Flag indicating the presence of a + Global Color Table; if the flag is set, the Global Color Table will + immediately follow the Logical Screen Descriptor. This flag also + selects the interpretation of the Background Color Index; if the + flag is set, the value of the Background Color Index field should + be used as the table index of the background color. (This field is + the most significant bit of the byte.) + + Values : 0 - No Global Color Table follows, the Background + Color Index field is meaningless. + 1 - A Global Color Table will immediately follow, the + Background Color Index field is meaningful. + + iv) Color Resolution - Number of bits per primary color available + to the original image, minus 1. This value represents the size of + the entire palette from which the colors in the graphic were + selected, not the number of colors actually used in the graphic. + For example, if the value in this field is 3, then the palette of + the original image had 4 bits per primary color available to create + the image. This value should be set to indicate the richness of + the original palette, even if not every color from the whole + palette is available on the source machine. + + v) Sort Flag - Indicates whether the Global Color Table is sorted. + If the flag is set, the Global Color Table is sorted, in order of + decreasing importance. Typically, the order would be decreasing + frequency, with most frequent color first. This assists a decoder, + with fewer available colors, in choosing the best subset of colors; + the decoder may use an initial segment of the table to render the + graphic. + + Values : 0 - Not ordered. + 1 - Ordered by decreasing importance, most + important color first. + + vi) Size of Global Color Table - If the Global Color Table Flag is + set to 1, the value in this field is used to calculate the number + of bytes contained in the Global Color Table. To determine that + actual size of the color table, raise 2 to [the value of the field + + 1]. Even if there is no Global Color Table specified, set this + field according to the above formula so that decoders can choose + the best graphics mode to display the stream in. (This field is + made up of the 3 least significant bits of the byte.) + + vii) Background Color Index - Index into the Global Color Table for + + + + + + + + 10 + + + the Background Color. The Background Color is the color used for + those pixels on the screen that are not covered by an image. If the + Global Color Table Flag is set to (zero), this field should be zero + and should be ignored. + + viii) Pixel Aspect Ratio - Factor used to compute an approximation + of the aspect ratio of the pixel in the original image. If the + value of the field is not 0, this approximation of the aspect ratio + is computed based on the formula: + + Aspect Ratio = (Pixel Aspect Ratio + 15) / 64 + + The Pixel Aspect Ratio is defined to be the quotient of the pixel's + width over its height. The value range in this field allows + specification of the widest pixel of 4:1 to the tallest pixel of + 1:4 in increments of 1/64th. + + Values : 0 - No aspect ratio information is given. + 1..255 - Value used in the computation. + + d. Extensions and Scope. The scope of this block is the entire Data + Stream. This block cannot be modified by any extension. + + e. Recommendations. None. + + +19. Global Color Table. + + a. Description. This block contains a color table, which is a sequence of + bytes representing red-green-blue color triplets. The Global Color Table + is used by images without a Local Color Table and by Plain Text + Extensions. Its presence is marked by the Global Color Table Flag being + set to 1 in the Logical Screen Descriptor; if present, it immediately + follows the Logical Screen Descriptor and contains a number of bytes + equal to + 3 x 2^(Size of Global Color Table+1). + + This block is OPTIONAL; at most one Global Color Table may be present + per Data Stream. + + b. Required Version. 87a + + + + + + + + + + + + + + + + + + + + + + + 11 + + + c.

Each image in the Data Stream is composed of an Image + Descriptor, an optional Local Color Table, and the image data. Each + image must fit within the boundaries of the Logical Screen, as defined + in the Logical Screen Descriptor. + + The Image Descriptor contains the parameters necessary to process a table + based image. The coordinates given in this block refer to coordinates + within the Logical Screen, and are given in pixels. This block is a + Graphic-Rendering Block, optionally preceded by one or more Control + blocks such as the Graphic Control Extension, and may be optionally + followed by a Local Color Table; the Image Descriptor is always followed + by the image data. + + This block is REQUIRED for an image. Exactly one Image Descriptor must + be present per image in the Data Stream. An unlimited number of images + may be present per Data Stream. + + b.

An image + is interlaced in a four-pass interlace pattern; see Appendix E for + details. + + Values : 0 - Image is not interlaced. + 1 - Image is interlaced. + + viii) Sort Flag - Indicates whether the Local Color Table is + sorted. If the flag is set, the Local Color Table is sorted, in + order of decreasing importance. Typically, the order would be + decreasing frequency, with most frequent color first.

This block can modify the + Image Descriptor Block and the Plain Text Extension. + + e. Recommendations. + + i) Disposal Method - The mode Restore To Previous is intended to be + used in small sections of the graphic; the use of this mode imposes + severe demands on the decoder to store the section of the graphic + that needs to be saved. For this reason, this mode should be used + sparingly. This mode is not intended to save an entire graphic or + large areas of a graphic; when this is the case, the encoder should + make every attempt to make the sections of the graphic to be + restored be separate graphics in the data stream. In the case where + a decoder is not capable of saving an area of a graphic marked as + Restore To Previous, it is recommended that a decoder restore to + the background color. + + ii) User Input Flag - When the flag is set, indicating that user + input is expected, the decoder may sound the bell (0x07) to alert + the user that input is being expected. In the absence of a + specified Delay Time, the decoder should wait for user input + indefinitely. It is recommended that the encoder not set the User + Input Flag without a Delay Time specified. + + +24. Comment Extension. + + a. Description. The Comment Extension contains textual information which + is not part of the actual graphics in the GIF Data Stream. It is suitable + for including comments about the graphics, credits, descriptions or any + other type of non-control and non-graphic data.

Plain Text Extension. + + a. Description. The Plain Text Extension contains textual data and the + parameters necessary to render that data as a graphic, in a simple form. + The textual data will be encoded with the 7-bit printable ASCII + characters. Text data are rendered using a grid of character cells + + + + + + + + + 19 + + + defined by the parameters in the block fields. Each character is rendered + in an individual cell. The textual data in this block is to be rendered + as mono-spaced characters, one character per cell, with a best fitting + font and size. For further information, see the section on + Recommendations below. The data characters are taken sequentially from + the data portion of the block and rendered within a cell, starting with + the upper left cell in the grid and proceeding from left to right and + from top to bottom. Text data is rendered until the end of data is + reached or the character grid is filled. The Character Grid contains an + integral number of cells; in the case that the cell dimensions do not + allow for an integral number, fractional cells must be discarded; an + encoder must be careful to specify the grid dimensions accurately so that + this does not happen. This block requires a Global Color Table to be + available; the colors used by this block reference the Global Color Table + in the Stream if there is one, or the Global Color Table from a previous + Stream, if one was saved. This block is a graphic rendering block, + therefore it may be modified by a Graphic Control Extension. This block + is OPTIONAL; any number of them may appear in the Data Stream. + + b.

If characters less than 0x20 or greater than 0xf7 are + encountered, it is recommended that the decoder display a Space character + (0x20). The encoder should use grid and cell dimensions such that an + integral number of cells fit in the grid both horizontally as well as + vertically. For broadest compatibility, character cell dimensions should + be around 8x8 or 8x16 (width x height); consider an image for unusual + sized text. + + +26. Application Extension. + + a. Description.

GIF Grammar. + +A Grammar is a form of notation to represent the sequence in which certain +objects form larger objects. A grammar is also used to represent the number of +objects that can occur at a given position. The grammar given here represents +the sequence of blocks that form the GIF Data Stream. A grammar is given by +listing its rules. Each rule consists of the left-hand side, followed by some +form of equals sign, followed by the right-hand side. In a rule, the +right-hand side describes how the left-hand side is defined. The right-hand +side consists of a sequence of entities, with the possible presence of special +symbols. The following legend defines the symbols used in this grammar for GIF. + +Legend: <> grammar word + ::= defines symbol + * zero or more occurrences + + one or more occurrences + | alternate element + [] optional element + +Example: + + ::= Header * Trailer + +This rule defines the entity as follows. It must begin with a +Header. The Header is followed by an entity called Logical Screen, which is +defined below by another rule. The Logical Screen is followed by the entity +Data, which is also defined below by another rule. Finally, the entity Data is +followed by the Trailer. Since there is no rule defining the Header or the +Trailer, this means that these blocks are defined in the document. The entity +Data has a special symbol (*) following it which means that, at this position, +the entity Data may be repeated any number of times, including 0 times. For +further reading on this subject, refer to a standard text on Programming +Languages. + + +The Grammar. + + ::= Header * Trailer + + ::= Logical Screen Descriptor [Global Color Table] + + ::= | + + + ::= [Graphic Control Extension] + + ::= | + Plain Text Extension + + ::= Image Descriptor [Local Color Table] Image Data + + ::= Application Extension | + Comment Extension + + + + + + + + + + 26 + + +NOTE : The grammar indicates that it is possible for a GIF Data Stream to +contain the Header, the Logical Screen Descriptor, a Global Color Table and the +GIF Trailer. This special case is used to load a GIF decoder with a Global +Color Table, in preparation for subsequent Data Streams without color tables at +all. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + 27 + + +Appendix +C. Glossary. + +Active Color Table - Color table used to render the next graphic. If the next +graphic is an image which has a Local Color Table associated with it, the +active color table becomes the Local Color Table associated with that image. +If the next graphic is an image without a Local Color Table, or a Plain Text +Extension, the active color table is the Global Color Table associated with the +Data Stream, if there is one; if there is no Global Color Table in the Data +Stream, the active color table is a color table saved from a previous Data +Stream, or one supplied by the decoder. + +Block - Collection of bytes forming a protocol unit. In general, the term +includes labeled and unlabeled blocks, as well as Extensions. + +Data Stream - The GIF Data Stream is composed of blocks and sub-blocks +representing images and graphics, together with control information to render +them on a display device. All control and data blocks in the Data Stream must +follow the Header and must precede the Trailer. + +Decoder - A program capable of processing a GIF Data Stream to render the +images and graphics contained in it. + +Encoder - A program capable of capturing and formatting image and graphic +raster data, following the definitions of the Graphics Interchange Format. + +Extension - A protocol block labeled by the Extension Introducer 0x21. + +Extension Introducer - Label (0x21) defining an Extension. + +Graphic - Data which can be rendered on the screen by virtue of some algorithm. +The term graphic is more general than the term image; in addition to images, +the term graphic also includes data such as text, which is rendered using +character bit-maps. + +Image - Data representing a picture or a drawing; an image is represented by an +array of pixels called the raster of the image. + +Raster - Array of pixel values representing an image. + + + + + + + + + + + + + + + + + + + + + + + + + 28 + + +Appendix +D. Conventions. + +Animation - The Graphics Interchange Format is not intended as a platform for +animation, even though it can be done in a limited way. + +Byte Ordering - Unless otherwise stated, multi-byte numeric fields are ordered +with the Least Significant Byte first. + +Color Indices - Color indices always refer to the active color table, either +the Global Color Table or the Local Color Table. + +Color Order - Unless otherwise stated, all triple-component RGB color values +are specified in Red-Green-Blue order. + +Color Tables - Both color tables, the Global and the Local, are optional; if +present, the Global Color Table is to be used with every image in the Data +Stream for which a Local Color Table is not given; if present, a Local Color +Table overrides the Global Color Table. However, if neither color table is +present, the application program is free to use an arbitrary color table. If +the graphics in several Data Streams are related and all use the same color +table, an encoder could place the color table as the Global Color Table in the +first Data Stream and leave subsequent Data Streams without a Global Color +Table or any Local Color Tables; in this way, the overhead for the table is +eliminated. It is recommended that the decoder save the previous Global Color +Table to be used with the Data Stream that follows, in case it does not contain +either a Global Color Table or any Local Color Tables. In general, this allows +the application program to use past color tables, significantly reducing +transmission overhead. + +Extension Blocks - Extensions are defined using the Extension Introducer code +to mark the beginning of the block, followed by a block label, identifying the +type of extension. Extension Codes are numbers in the range from 0x00 to 0xFF, +inclusive. Special purpose extensions are transparent to the decoder and may be +omitted when transmitting the Data Stream on-line. The GIF capabilities +dialogue makes the provision for the receiver to request the transmission of +all blocks; the default state in this regard is no transmission of Special +purpose blocks. + +Reserved Fields - All Reserved Fields are expected to have each bit set to zero +(off). + + + + + + + + + + + + + + + + + + + + + + + 29 + + +Appendix +E. Interlaced Images. + +The rows of an Interlaced images are arranged in the following order: + + Group 1 : Every 8th. row, starting with row 0.

Variable-Length-Code LZW Compression. + +The Variable-Length-Code LZW Compression is a variation of the Lempel-Ziv +Compression algorithm in which variable-length codes are used to replace +patterns detected in the original data. The algorithm uses a code or +translation table constructed from the patterns encountered in the original +data; each new pattern is entered into the table and its index is used to +replace it in the compressed stream. + +The compressor takes the data from the input stream and builds a code or +translation table with the patterns as it encounters them; each new pattern is +entered into the code table and its index is added to the output stream; when a +pattern is encountered which had been detected since the last code table +refresh, its index from the code table is put on the output stream, thus +achieving the data compression. The expander takes input from the compressed +data stream and builds the code or translation table from it; as the compressed +data stream is processed, codes are used to index into the code table and the +corresponding data is put on the decompressed output stream, thus achieving +data decompression. The details of the algorithm are explained below. The +Variable-Length-Code aspect of the algorithm is based on an initial code size +(LZW-initial code size), which specifies the initial number of bits used for +the compression codes. When the number of patterns detected by the compressor +in the input stream exceeds the number of patterns encodable with the current +number of bits, the number of bits per LZW code is increased by one. + +The Raster Data stream that represents the actual output image can be +represented as: + + 7 6 5 4 3 2 1 0 + +---------------+ + | LZW code size | + +---------------+ + + +---------------+ ----+ + | block size | | + +---------------+ | + | | +-- Repeated as many + | data bytes | | times as necessary. + | | | + +---------------+ ----+ + + . . . . . . ------- The code that terminates the LZW + compressed data must appear before + Block Terminator. + +---------------+ + |0 0 0 0 0 0 0 0| Block Terminator + +---------------+ + +The conversion of the image from a series of pixel values to a transmitted or +stored character stream involves several steps. In brief these steps are: + +1. Establish the Code Size - Define the number of bits needed to represent the +actual data. + +2. Compress the Data - Compress the series of image pixels to a series of + + + + + + + + 31 + + +compression codes. + +3. Build a Series of Bytes - Take the set of compression codes and convert to a +string of 8-bit bytes. + +4. Package the Bytes - Package sets of bytes into blocks preceded by character +counts and output. + +ESTABLISH CODE SIZE + +The first byte of the Compressed Data stream is a value indicating the minimum +number of bits required to represent the set of actual pixel values. Normally +this will be the same as the number of color bits. Because of some algorithmic +constraints however, black & white images which have one color bit must be +indicated as having a code size of 2. +This code size value also implies that the compression codes must start out one +bit longer. + +COMPRESSION + +The LZW algorithm converts a series of data values into a series of codes which +may be raw values or a code designating a series of values. Using text +characters as an analogy, the output code consists of a character or a code +representing a string of characters. + +The LZW algorithm used in GIF matches algorithmically with the standard LZW +algorithm with the following differences: + +1. A special Clear code is defined which resets all compression/decompression +parameters and tables to a start-up state. The value of this code is 2**. For example if the code size indicated was 4 (image was 4 bits/pixel) +the Clear code value would be 16 (10000 binary). The Clear code can appear at +any point in the image data stream and therefore requires the LZW algorithm to +process succeeding codes as if a new data stream was starting. Encoders should +output a Clear code as the first code of each image data stream. + +2. An End of Information code is defined that explicitly indicates the end of +the image data stream. LZW processing terminates when this code is encountered. +It must be the last code output by the encoder for an image. The value of this +code is +1. + +3. The first available compression code value is +2. + +4. The output codes are of variable length, starting at +1 bits per +code, up to 12 bits per code. This defines a maximum code value of 4095 +(0xFFF). Whenever the LZW code value would exceed the current code length, the +code length is increased by one. The packing/unpacking of these codes must then +be altered to reflect the new code length. + +BUILD 8-BIT BYTES + +Because the LZW compression used for GIF creates a series of variable length +codes, of between 3 and 12 bits each, these codes must be reformed into a +series of 8-bit bytes that will be the characters actually stored or +transmitted. This provides additional compression of the image. The codes are +formed into a stream of bits as if they were packed right to left and then + + + + + + + + 32 + + +picked off 8 bits at a time to be output. + +Assuming a character array of 8 bits per character and using 5 bit codes to be +packed, an example layout would be similar to: + + + +---------------+ + 0 | | bbbaaaaa + +---------------+ + 1 | | dcccccbb + +---------------+ + 2 | | eeeedddd + +---------------+ + 3 | | ggfffffe + +---------------+ + 4 | | hhhhhggg + +---------------+ + . . . + +---------------+ + N | | + +---------------+ + + +Note that the physical packing arrangement will change as the number of bits +per compression code change but the concept remains the same. + +PACKAGE THE BYTES + +Once the bytes have been created, they are grouped into blocks for output by +preceding each block of 0 to 255 bytes with a character count byte. A block +with a zero byte count terminates the Raster Data stream for a given image. +These blocks are what are actually output for the GIF image. This block format +has the side effect of allowing a decoding program the ability to read past the +actual image data if necessary by reading block counts and then skipping over +the data. + + + +FURTHER READING + +[1] Ziv, J. and Lempel, A. : "A Universal Algorithm for Sequential Data +Compression", IEEE Transactions on Information Theory, May 1977. +[2] Welch, T. : "A Technique for High-Performance Data Compression", Computer, +June 1984. +[3] Nelson, M.R. : "LZW Data Compression", Dr. Dobb's Journal, October 1989. + + + + + + + + + + + + + + + + + + + 33 + + +Appendix +G.

The GIFLIB Library

+ +
+Gershon Elber, May 1991
+Eric S. Raymond, Sep 1992
+Toshio Kuratomi, May 2004
+
+ +The Graphics Interchange Format(c) is the Copyright property of +CompuServe Incorporated. GIF(sm) is a Service Mark property of CompuServe +Incorporated.

+ +Gershon wrote: "This library was written because I couldn't find +anything similar and I wanted one. I was inspired by the RLE Utah tool kit, +which I hoped to port to an IBM PC, but found it to be too machine specific, +and its compression ratio too low. I compromised on the GIF format, but I am +not sure how long 8 bits per pixel will be enough."

+ +This document explains the GIF library code in directory `lib'. The +code is collected into libgif.a which is used in all the utilities in +`util'. It can be used in any application needs to read/write the GIF +file format. This document does not explain the GIF file +format and assumes you know it, at least to the level of the GIF file +structure.

+ +When a GIF file is opened, a GIF file descriptor is created which +is a pointer to GifFileType structure as follows:

+ +


+typedef struct GifFileType {
+    int SWidth, SHeight,			       /* Screen dimensions. */
+	SColorResolution, 		 /* How many colors can we generate? */
+	SBackGroundColor;		/* I hope you understand this one... */
+    ColorMapObject *SColorMap;			      /* NULL if not exists. */
+    int ImageCount;				  /* Number of current image */
+    GifImageDesc Image;			   /* Block describing current image */
+    struct SavedImage *SavedImages;	/* Use this to accumulate file state */
+    VoidPtr Private;	  /* The regular user should not mess with this one! */
+} GifFileType;
+
+ +This structure was copied from gif_lib.h - the header file for the GIF +library. Any application program that uses the libgif.a library should +include it. Members beginning with S refer to GIF Screen; others hold +properties of the current image (a GIF file may have more than one image) +or point to allocated store used by various routines.

+ +The user almost never writes into this structure (exception: it may +occasionally useful to alter things in the SavedImages array), but can read +any of these items at any time it is valid (image information is invalid +until first image was read/write).

+ +As the library needs to keep its own internal data, a Private pointer +to hidden data is included. Applications should ignore this item.

+ +The library has no static data. This means that it is fully reentrant +and any number of GIF files (up to memory limits) can be opened for +read/write. Instead of the static data, internal structure pointed by the +Private pointer is used.

+ +The library allocates its own memory dynamically, on opening of files, +and releases that once closed. The user is never required to allocate +any memory for any of the functions of this library nor to free them +directly.

+ +In order to reduce disk access, the file buffer is increased to +FILE_BUFFER_SIZE (defined in gif_lib.h). The library was compiled in large +model on the PC as the memory allocated per file is quite big: about 17k for +decoding (DGIF_LIB.C), and 32k for encoding (EGIF_LIB.C), excluding the +FILE_BUFFER_SIZE.

+ +Here is a module summary:

+ +

+
egif_lib.c
Encoding routines, all prefixed with E.

+ +

dgif_lib.c
Decoding routines, all prefixed with D.

+ +

dev2gif.c
Routines to convert specific device buffers into GIF files.

+ +

gifalloc.c
Routines for colormap handling and GIF record allocation.

+ +

gif_font.c
The 8x8 font table for the GIF utility font.

+ +

gif_err.c
Error handler for the library.

+

+ +The library includes a sixth file of hash-function code which is accessed +internally only.

+ +

Most of the routines return GIF_ERROR (see gif_lib.h) if something +went wrong, GIF_OK otherwise. After an error return, the code in the +gif_err.c module can be used to do something about it.

+ +In addition, a module to parse command line arguments is supplied. +This module is called getarg.c and its headers are in getarg.h. See the header +of getarg.c for details on its usage.

+ +

Decoding (dgif_lib.c)

+ +The following functions are used to set up input from a GIF:

+ +


+GifFileType *DGifOpenFileName(char *GifFileName)
+
+ +Open a new GIF file using the given GifFileName, and read its Screen +information. + + +If any error occurs, NULL is returned and the error handler can be +used to get the exact error (see gif_err.c). + + +The file is opened in binary mode, and its buffer size is set to +FILE_BUFFER_SIZE bytes. + + +

+GifFileType *DGifOpenFileHandle(int GifFileHandle)
+
+ +Open a new GIF file using the given GifFileHandle, and read its Screen +information.

+ +If any error occurs, NULL is returned and the error handler can be +used to get the exact error (see gif_err.c).

+ +The file is opened in binary mode, and its buffer size is set to +FILE_BUFFER_SIZE bytes.

+ +Once you have acquired a handle on a GIF, there are two ways to read it in. +The high-level function + +


+int DGifSlurp(GifFileType)
+
+ +reads the rest of a complete (possibly multi-image) GIF file from the +indicated file handle into in-core allocated structures. It returns +GIF_OK on success, GIF_ERROR on failure.

+ +Once you have done this, all image, raster, and extension-block data in the +GIF is accessable in the SavedImages member (see the structures in fif_lib.h). +When you have modified the image to taste, write it out with EGifSpew().

+ +If you are handling large images on a memory-limited machine, you may need +to use the following functions for sequential read.

+ +


+int DGifGetScreenDesc(GifFileType *GifFile)
+
+ +Reads the screen information into the GifFile structure. Note this +routine is automatically called once a file is opened, and therefore +usually need not be called explicitly.

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +


+int DGifGetRecordType(GifFileType *GifFile, GifRecordType *GifType)
+
+ +As the GIF file can have different records in arbitrary order, this +routine should be called once the file was open to detect the next +record type, and act upon it. It can return these types in GifType:

+ +

+
1. UndefinedRecordType
something is wrong!

+ +

2. ScreenDescRecordType
screen information. As the screen info + is automatically read in when the file is open, this should + not happen.

+ +

3. ImageDescRecordType
next record is an image descriptor.

+ +

4. ExtensionRecordType
next record is extension block.

+ +

5. TerminateRecordType
last record reached, can close the file.

+

+The first two types can usually be ignored. The function +returns GIF_ERROR if something went wrong, GIF_OK otherwise. + +

+int DGifGetImageDesc(GifFileType *GifFile)
+
+ +Reads image information into the GifFile structure. +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +


+int DGifGetLine(GifFileType *GifFile, PixelType *GifLine, int GifLineLen)
+
+ +Load a block of pixels from the GIF file. The line can be +of any length. More than that, this routine may be interleaved with +DGifGetPixel until all pixels have been read.

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +

+int DGifGetPixel(GifFileType *GifFile, PixelType GifPixel)
+
+ +Loads one pixel from the GIF file. This routine may be interleaved +with DGifGetLine, until all pixels are +read. Because of the overhead per each call, use of this routine is +not recommended.

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +


+int DGifGetComment(GifFileType *GifFile, char *GifComment)
+
+ +Load a comment from the GIF file. Because DGifGetRecordType will +only tell if the record is of type extension, this routine should be +called iff it is known %100 that is must be a comment.

+ +For the definition of a comment, see EGifPutComment. Returns GIF_ERROR if +something went wrong, GIF_OK otherwise.

+ +


+int DGifGetExtension(
+        GifFileType *GifFile,
+        int *GifExtCode,
+        ByteType **GifExtension)
+
+ +Loads an extension block from the GIF file. Extension blocks +are optional in GIF files. This routine should be followed by +DGifGetExtensionNext.

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +


+int DGifGetExtensionNext(GifFileType *GifFile, ByteType **GifExtension)
+
+ +As extensions may contain more than one block, use this routine to +continue after DGifGetExtension, until *GifExtension is NULL.

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ + +


+int DGifGetCode(
+        GifFileType *GifFile, 
+        int *GifCodeSize, ByteType **GifCodeBlock)
+
+ +It sometimes may be desired to read the compressed code as is +without decoding it. This routine does exactly that (with +DGifGetCodeNext), and can be used instead of DGifGetLine.

+ +This compressed code information can be written out using the +EGifPutCode/EGifPutCodeNext sequence (see gifpos.c for example). +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +


+int DGifGetCodeNext(GifFileType *GifFile, ByteType **GifCodeBlock)
+
+ +See DGifGetCode above.

+ +


+int DGifGetLZCodes(GifFileType *GifFile, int *GifCode)
+
+ +This routine can be called instead of DGifGetLine/DGifGetPixel or +DGifGetCode/DGifGetCodeNext to get the 12 bits LZ codes of the images. +It will be used mainly for debugging purposes (see GifText.c for +example).

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +


+int DGifCloseFile(GifFileType *GifFile)
+
+ +Close GIF file and free all memory allocated for it. GifFile should +not be used after this routine has been called.

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +

Encoding (egif_lib.c)

+ +There are two ways to write out a GIF. The high-level function

+ +

+int EGifSpew(GifFileType *GifFile, int GifFileHandle)
+
+ +Writes a complete (possibly multi-image) GIF file to the indicated file +handle from in-core allocated structures created by a previous DGifSlurp() +or equivalent operations. Its arguments are a GIF file descriptor (as +above) and an ordinary output file descriptor.

+ +The file is written with a GIF87 stamp unless it contains one of the four +special extension blocks defined in GIF89, in which case it is written +with a GIF89 stamp.

+ +If you are handling large images on a memory-limited machine, you may need +to use the following functions for sequential write.

+ +


+GifFileType *EGifOpenFileName(char *GifFileName, int GifTestExistance)
+
+ +Open a new GIF file using the given GifFileName. If GifTestExistance +is TRUE, and file exists, the file is not destroyed, and NULL +returned.

+ +If any error occurs, NULL is returned and the error handler can be +used to get the exact error (see gif_err.c).

+ +The file is opened in binary mode, and its buffer size is set to +FILE_BUFFER_SIZE bytes.

+ +


+GifFileType *EGifOpenFileHandle(int GifFileHandle)
+
+ +Open a new GIF file using the given GifFileHandle.

+ +If any error occurs, NULL is returned and the error handler can be +used to get the exact error (see gif_err.c).

+ +The file is opened in binary mode, and its buffer size is set to +FILE_BUFFER_SIZE bytes.

+ +


+void EGifSetGifVersion(char *Version)
+
+ +Sets the GIF version of all files opened, until another call to this +routine is made. Version is a 3 characters string of the form "87a" +or "89a". No test is made to validate this string.

+ +


+int EGifPutScreenDesc(GifFileType *GifFile,
+        int GifWidth, int GifHeight,
+        int GifColorRes, int GifBackGround,
+        ColorMapObject *GifColorMap)
+
+ +Update the GifFile Screen parameters, in GifFile structure and in +the real file. If error occurs, returns GIF_ERROR (see gif_lib.h), +otherwise GIF_OK.

+ +This routine should be called immediately after the GIF file was +opened.

+ +


+int EGifPutImageDesc(GifFileType *GifFile,
+        int GifLeft, int GifTop,
+        int Width, int GifHeight,
+        int GifInterlace,
+        ColorMapObject *GifColorMap)
+
+ +Update GifFile Image parameters, in GifFile structure and in the real +file. if error occurs returns GIF_ERROR (see gif_lib.h), otherwise +GIF_OK.

+ +This routine should be called each time a new image must be +dumped to the file.

+ +


+int EGifPutLine(GifFileType *GifFile, PixelType *GifLine, int GifLineLen)
+
+ +Dumps a block of pixels out to the GIF file. The slab can be +of any length. More than that, this routine may be interleaved with +, until all pixels have been sent.

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +


+int EGifPutPixel(GifFileType *GifFile, PixelType GifPixel)
+
+ +Dumps one pixel to the GIF file. This routine may be interleaved with +EGifPutLine, until all pixels were sent. +Because of the overhead for each call, use of this routine is not +recommended.

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +


+int EGifPutComment(GifFileType *GifFile, char *GifComment)
+
+ +Uses extension GIF records to save a string as a comment is the file. +The extension code is 'C' (for Comment).

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +


+int EGifPutExtension(
+        GifFileType *GifFile,
+        int GifExtCode,
+        int GifExtLen,
+        void *GifExtension)
+
+ +Dumps the given extension block into the GIF file. Extension blocks +are optional in GIF file. Extension blocks of more than 255 bytes or +more than one block are not supported in this function. Please use +EGifPutExtensionFirst, EGifPutExtensionNext, and EGifPutExtensionLast +if your extension blocks may fall into this category.

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +


+int EGifPutExtensionFirst(
+        GifFileType * GifFile,
+        int GifExtCode,
+        int GifExtLen,
+        const VoidPtr GifExtension)
+
+Dumps the beginning of a GIF extension block to a GIF file. Extension blocks +are optional in GIF files. This function outputs the meta information +necessary to a GIF extension block and the extension data described in the +GifExtension argument.

+ +Further blocks of the GIF Extension should be dumped using +EGifPutExtensionNext. When finished with this extension block, +EGifPutExtensionLast should be called to output the block termination.

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +


+int EGifPutExtensionNext(
+        GifFileType * GifFile,
+        int GifExtCode,
+        int GifExtLen,
+        const VoidPtr GifExtension)
+
+Dumps a subblock of a GIF extension to a GIF File. Extension blocks are +optional in GIF files. This function will write the Extension Data in +GifExtension to the file as a subblock of the preceding Extension Block. +Repeat calling of this function until all data subblocks have been output.

+ +Note that EGifPutExtensionFirst needs to be called before any calls to this +function. EGifPutExtensionLast should be called to finish the Extension +block after all data subblocks have been output.

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +


+int EGifPutExtensionLast(
+        GifFileType * GifFile,
+        int GifExtCode,
+        int GifExtLen,
+        const VoidPtr GifExtension)
+
+Dumps an optional GIF extension data subblock and the GIF extension block +terminator to a GIF File. Extension blocks are optional in GIF files. This +function will write the Extension Data in GifExtension to the file as a +subblock of the preceding Extension Block. Then it will output the GIF +extension block terminator to end the current Extension block. As a special +case, if GifExtLen is zero, the function will assume there isn't another +data block to output and will simply write the block terminator.

+ +Note that a call to EGifPutExtensionFirst is needed to open the GIF +Extension Block prior to calling this function.

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +


+int EGifPutCode(
+        GifFileType *GifFile,
+        int *GifCodeSize,
+        ByteType **GifCodeBlock)
+
+ +It sometimes may be desired to write the compressed code as is +without decoding it. For example a filter for a GIF file that change +only screen size (GifPos), does not need the exact pixel values. +Piping out the compressed image as is makes this process much +faster.

+ +This routine does exactly that (with EGifPutCodeNext), and can be +used instead of EGifPutLine. You'll usually use this with the +DGifGetCode/DgifGetCodeNext routines, which reads the compressed +code, while EGifPutCode/EGifPutCodeNext write it out. See gifpos.c +for example.

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +


+int EGifPutCodeNext(GifFileType *GifFile, ByteType **GifCodeBlock)
+
+ +See EGifPutCode above.

+ +


+int EGifCloseFile(GifFileType *GifFile)
+
+ +Close a GIF file and free all memory allocated for it. gif-file$ +should not be used, once this routine was called.

+ +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

+ +

Color map handling and allocation routines

+ +

+ColorMapObject *MakeMapObject(int ColorCount, GifColorType *ColorMap)
+
+ +Allocate storage for a color map object with the given number of +RGB triplet slots. If the second argument is non-NULL, initialize +the color table portion of the new map from it. Returns NULL if +memory is exhausted or if the size is not a power of 2 <= 256.

+ +


+void FreeMapObject(ColorMapObject *Object)
+
+ +Free the storage occupied by a ColorMapObject that is no longer needed.

+ +


+ColorMapObject *UnionColorMap(
+        ColorMapObject *ColorIn1, ColorMapObject *ColorIn2,
+        GifPixelType ColorTransIn2[])
+
+ +Create the union of two given color maps and return it. If the result +won't fit into 256 colors, NULL is returned, the allocated union +otherwise. ColorIn1 is copied as it to ColorUnion, while colors from +ColorIn2 are copied iff they didn't exist before. ColorTransIn2 maps +the old ColorIn2 into ColorUnion color map table.

+ +


+SavedImage *GifAttachImage(GifFileType *GifFile)
+
+ +Add an image block to the SavedImages array. The image block is +initially zeroed out. This image block will be seen by any following +EGifSpew() calls. + + +

The GIF Utility Font

+ +The 8x8 utility font used in text2gif and gifcolor lives in the library +module gif_font.c, in a table called AsciiTable. The library header file +includes suitable externs and defines.

+ +The GIF utility font support includes entry points for drawing legends +on in-core images, drawing boxes and rectangles, and boxing text. +These entry points are as follows:

+ +


+void DrawText(
+        SavedImage *Image,
+        const int x, const int y,
+        const char *legend,
+        const int color)
+
+ +Draw text using the 8x8 utility font on the saved image. Upper left +corner of the text is at image pixel (x, y). Use the specified +color index.

+ +


+void DrawBox(SavedImage *Image,
+        const int x, const int y,
+        const int w, const int h,
+        const int color)
+
+ +Draw a box on the saved image. Upper left corner of the box is at +image pixels (x, y), width is w, height is h. Use the specified color +index.

+ +


+void DrawRectangle(SavedImage *Image,
+        const int x, const int y,
+        const int w, const int h,
+        const int color)
+
+ +Draw a (filled) rectangle on the saved image. Upper left corner of +the box is at image pixels (x, y), width is w, height is h. Use the +specified color index.

+ +


+void DrawBoxedText(SavedImage *Image,
+        const int x, const int y,
+        const char *legend,
+        const int border,
+        const int bg, const int fg)
+
+ +Draw text on a filled rectangle. The rectangle will be sized to fit +the text, with upper left hand corner at (x, y) on the saved image. +The `border' argument specifies a pixel margin around the text. The +`bg' argument is the color table index to fill the rectangle with; +`fg' is the color table index to draw the text with.

+ +This function interprets some characters in the legend string +specially. A tab (\t) is interpreted as a command to center the +following text in the box. A carriage return (\r) is interpreted +as a request for a line break.

+ +

Error Handling (egif_lib.c)

+ +

+void PrintGifError(void)
+
+ +Print a one-line diagnostic on the last giflib error to stderr.

+ +


+int GifLastError(void)
+
+ +Return the number of the last giflib error, and clear the error. +The error types are defined in gif_lib.h.

+ +Note it is the user's responsibility to call the file closing +routine, so the file will be closed (if was opened), and allocated +memory will be released.

+ +

Device Specific (XXX2gif.c)

+ +

+int DumpScreen2Gif(char *FileName, int ReqGraphDriver, int ReqGraphMode1,
+						       int ReqGraphMode2)
+
+ +Dumps the whole device buffer as specified by GraphDriver and +GraphMode (as defined in TC 2.0 graphics.h) into FileName as GIF file. +Current devices supported:

+ +

+	1. Hercules.
+
+	2. EGA, EGA64, EGAMONO (all modes - see TC graphics.h).
+
+	3. VGA (all modes - see TC graphics.h).
+

Command Line Parsing

+ +

+int GAGetArgs(int argc, char **argv, char *CtrlStr, ...)
+
+ +Main routine of this module. Given argc & argv as received by +the main procedure, the command line CtrlStr, and the addresses of +all parameters, parse the command line, and update the parameters.

+ +The CtrlStr defines what types of variables should follow. Look at the +beginning of getarg.c for exact usage.

+ +Returns 0 if successful, error number (as defined by getarg.h) otherwise.

+ +


+void GAPrintErrMsg(int Error)
+
+ +If an error occurred in GAGetARgs, this routine may be used to print +one line diagnostic to stderr.

+ +


+void GAPrintHowTo(char *CtrlStr)
+
+ +Given the same CtrlStr as for GAGetArgs, can be used to print a one line +'how to use'.

+ +

Skeletons of GIF filters

+ +If you are developing on a virtual-memory OS such as most flavors of +UNIX, or are otherwise sure of having enough memory to keep all of GIFs you +need to operate in core, writing a filter is trivial. See the file +gifspnge.c in util.

+ +A sequential filter skeleton will usually look like the example file +giffiltr.c in util.

+ +

Please look at the utilities in the util directory for more ideas once +you feel comfortable with these skeletons. Also try to follow the coding +standards of this package if you want the maintainer to officially add your new +utility to it.

[-q] +
Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout + of running scan lines. Use -q- to invert.

+ +

[-a] +
Assemble. This is the default, and the GifFile(s) are assembled to + stdout. Note the screen descriptor (including screen color map) is taken + from the first file, while other screen descriptors are ignored. + As this tool requires at least 2 GIF files as input, no attempt will be + made to read stdin if none specified on command line.

[-i Xmin Ymin Xmax Ymax] +
Clip first image to the dimensions as specified + by the 4 coordinates (Xmin Ymin Xmax Ymax) of a box clipping region.

+ + For example: '-i 11 22 33 44' will crop the box from top left [11,22] + to bottom right [33,44] out of the first image.

+ + If the first parameter is bigger than third one (Xmin > Xmax) they are + swapped. Same for Y.

+ + The dimensions of the clipped image must be confined to original image + width and height. Note the clipped image includes both the min & max + boundary; an image of width W can have coordinates 0 to W-1 (zero based).

+ +

[-c] +
Complement. This removes horizontal and/or vertical bands of the + image. For example `-c -i 638 3 658 13' would remove a horizontal band + 11 pixels deep beginning at raster line 3, and a vertical band 21 pixels + right beginning at pixel 658.

gifcompose

+ +The gifcompose program uses the GIFLIB utility tools to support a minilanguage +for describing GIF pasteup sequences.

+ +

Usage:

+ +
+gifcompose [-v] <specfile
+
+ +

Specification Syntax

+ +The gifcompose tool takes a series of text lines and interprets them as +commands to do pasteup operations. The commands are:

+ +

Generators

+ +
+
gif <name>
+ Paste in <name>.gif

+ +

raw <name> <width> <height>
+ Paste in the given raw-format file (no suffix supplied). Raw format + is a stream of 8-bit indices into the EGA color map. Accordingly, the + width and height must be specified, and the source must be exactly + width times height bytes long.

+ +

rgb <name> <width> <height>
+ Paste in the given RGB-format file (no suffix supplied). Raw format + is a stream of 24-bit color values. Accordingly, the width and height + must be specified, and the source must be exactly 3 times width times + height bytes long.

+ +

rle <name>
+ Paste in the given RLE-format file (no suffix supplied). This converts + the Utah Raster Kit format to GIF.

+ +

text <text> [foreground <index>] [color <r> <g> <b>]
+ Copy 8x8 monospace font, with transparent background and index 1 as + foreground. If the text string contains whitespaces, they must be + escaped or the string must be quoted (shell conventions).

+ + The optional suffix `foreground <n>' sets the foreground color index. + The optional suffix `color <r> <g> <b>' sets the RGB color to be used + for the foreground index.

+

+ +Each generator operation may be followed by any combination of the +following suffixes: + +

Modifiers

+ +
at <x> <y>
+ Place the image at the given (upper-left-hand-corner) coordinates + in the pasted-up result.

+ +

clip <name> <top-x> <top-y> <bottom-x> <bottom-y>
+ Clip image using the given rectange, paste it onto.

+ +

xflip
+ Flip the image around the X axis before placing it.

+ +

yflip
+ Flip the image around the Y axis before placing it.

+ +

left
+ Rotate the image 90 degrees counterclockwise before placing it.

+ +

right
+ Rotate the image 90 degrees clockwise before placing it.

+ +

Target Operations

+ +
screen size <x-size> <y-size>
+ Set the global screen size of the final image.

+ +

screen position <x> <y>
+ Set the global screen position of the final image.

+ +

Comments

+ +Comments or comment lines may be preceded with `#' and will be ignored.

+ +

Memory required:

+ +Proportional to the size of the largest pasted image.

+ +

Options:

+ +
+
[-v] +
Emit a report on each composition action to stderr as it happens. +
+ +

Bugs:

+ +The suffix sequence `left left' sometimes mysteriously fails to work, +probably due to some restriction in gifflip.

+ +No support for resizing or odd-angle rotations yet.

+ +The `color' suffix of text is a no-op, because the present version of +gifovly throws away color tables.

+ +Error checking is rudimentary.

+
+ +If the semantics of the `screen height', `screen width', `screen background', +`image top', `image left' declarations aren't obvious to you, what are you +doing with this software?

+ +A color table declares color indices (in ascending order from 0) and +assiciates them with key characters. These characters can later be used in +raster blocks. As these must be printable and non-whitespace, you can only +specify 94 colors per icon. Life is like that sometimes.

+ +A raster block is just a block of key characters. It should be sized correctly +for the `image bits' declaration that leads it.

+ +The `comment' or `plaintext' keywords lead defined GIF89 extension +record data (the other two GIF89 types, graphics control and application +block, are not yet supported). You can also say `extension' followed +by a hexadecimal record type. All of these extension declarations +must be followed by an extension block, which is terminated by the +keyword `end' on its own line.

+ +An extension block is a series of text lines, each interpreted as a string of +bytes to fill an argument block (the terminating newline is stripped). Text +may include standard C-style octal and hex escapes preceded by a backslash.

+ +All tokens are interpreted as decimal numerals; +tokens are interpreted as two hex digits (a byte). All coordinates are +zero-origin with the top left corner (0,0). Range checking is weak and +signedness checking nonexistent; caveat hacker!

+ +In general, the amount of whitespace and order of declarations within a +header or image block is not significant, except that a raster picture +must immediately follow its `image bits' bits declaration.

+ +The `include' declaration includes a named GIF as the next image. The global +color maps of included GIFs are merged with the base table defined by any +`screen color' declaration. All images of an included multi-image GIF will +be included in order.

+ +Comments may be preceded with `#' and will be ignored.

+ +

Memory required:

+ +For the compilation mode, proportional to the size of the input file. For +dumping, proportional to the line size of the widest GIF.

+ +

Options:

+ +
+
[-q] +
Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout + of running scan lines. Use -q- to invert.

+ +

[-d] +
Dump the input GIF file(s) into the text form described above.

+ +

[-t] +
Specify name characters to use when dumping raster blocks. Only + valid with -d option.

+ +

[-h] +
Print one line of command line help, similar to Usage above.

+

+ +

Bugs:

+ +Because there are only 94 characters unambiguously usable for raster blocks, +an attempt to dump a GIF with a larger color map will fail.

+ +Error checking is rudimentary.

+ +

Example:

+ +A sample icon file called `sample.ico' is included in the pic directory.

Introduction to GIFLIB

+ +GIFLIB is a package of portable tools and library routines for working +with GIF images. You can find the latest version at the GIFLIB home +page http://www.ccil.org/~esr/giflib.

+ +The Graphics Interchange Format(c) specification is the copyrighted +property of CompuServe Incorporated. GIF(sm) is a service mark +property of CompuServe Incorporated. As this package existed before +UniSys's lawyeritis attack of New Years' Day 1995, it is grandfathered +in under their license terms and you do not have to pay fees +for using it.

+ +This package has been released under an X Consortium-life freeware +license. Use and copy as you see fit. If you make useful changes, +add new tools, or find and fix bugs, please send your mods to the +maintainers for general distribution.

+ +The util directory includes programs to clip, rotate, scale, and +position GIF images. It includes an X11 viewer, code to dump GIFs to +an Epson-compatible printer in graphics mode, and many conversion +utilities. These are no replacement for an interactive graphics +editor, but they can be very useful for scripted image generation or +transformation.

+ +The library includes program-callable entry points for reading and writing +GIF files, an 8x8 utility font for embedding text in GIFs, and an error +handler. GIF manipulation can be done at a relatively low level by +sequential I/O (which automatically does/undoes image compression) or at +a higher level by slurping an entire GIF into allocated core.

+ +This library speaks both GIF87a and GIF89. The differences between +GIF87 and GIF89 are minor: in the latter, the interpretation of some +extension block types is defined. The library never needs to actually +interpret these, but giftext notices them.

+ +

Utilities

+ +Here is a summary of the utilities in this package. If you're looking +at this page through a web browser, each utility name should be a +hotlink to HTML documentation.

C Code Templates

+ +
+
giffiltr +
template code for filtering a GIF sequentially +
gifspnge +
template code for filtering a GIF with in-core operations +
+ +Under MS-DOS, most filters will print the current input scan line number +(counting up) whenever they read image input, and will print output image line +number (counting down) when they dump output. Utilities that only read or +write always print in increasing order. Utilities (like GifPos that only +change positions) that copy the image as a block of compressed data will print +nothing --- they cannot identify a scan line number, and are enough faster that +the feedback to the user doesn't seem necessary.

+ +Some of the utilities require memory on the order of the whole screen, while +others read one scan line at a time. Each utility HTML file has entry called +Memory Usage which will be one of:

+ +

+
Line
memory required is on the order of one scan line +
Image
proportional to the size of the biggest image in GIF file +
Screen
proportional to GIF screen size +
+ +In all cases a byte is allocated per pixel, so an image of 320 by 200 pixels +will requires approximately 64k bytes of main memory.

+ +

Library Functions

+ +The library contains two groups of C functions. One group does sequential +I/O on the stream-oriented GIF format. The other supports grabbing an +entire GIF into allocated core, operating on it in core, and then writing +the modified in-core GIF out to disk.

+ +Unless you are on a 286 or some other very memory-limited machine +running under DOS, you probably want to use the second group.

+ +Detailed documentation on the library entry points is in gif_lib.html. Library error codes are +described in liberror.html

+ +

The GIF Standard

+ +The doc subdurector includes flat-ASCII descriptions of GIF89 format and Lempel-Ziv +Compression.

+ +

History

+ +This package was originally written by Gershon Elber +in 1990 on an IBM PC under MS-DOS using Borland Turbo C. He made it portable +to several UNIX environments.

+ +The 2.1 version featured substantial changes and additions by Eric +S. Raymond . These included the +DGifSlurp/EGifSpew function pair for enabling non-sequential +operations on GIF images and the tools icon2gif, gifovly, gifburst, and +gifcompose.

+ +The 2.4 version converted all the docs from an idiosyncratic +plain-text formal to to HTML.

+ +

Package Status

+ +GIFLIB's current maintainer is Eric S. Raymond. You can find his home +page at http://www.ccil.org/esr.

+ +GIFLIB is not under active development, but bug fixes are being accepted.

See GIFENCOD.GIF for a flow diagram of the encoding process. This +uses a tree method to search if a new string is already in the table, which +is much simpler, faster, and easier to understand than hashing. + +=========================================================================== + +DECODER + +We will now see if we can regenerate the original data stream and duplicate +the table looking only at the output data stream generated by the encoder +on the previous page. The output data stream is: + + A B 6 8 B 10 9 A A C D 14 16 D C 8 .... + +The docoding process is harder to see, but easier to implement, than the +encoding process. The data is taken in pairs, and a new code is assigned to +each pair. The prefix is the left side of the pair, and the suffix is the +color that the right side of the pair decomposes to from the table. The +decomposition is done by outputing the suffix of the code, and using the +prefix as the new code. The process repeats until the prefix is a single +color, and it is output too. The output of the decomposition is pushed onto +a stack, and then poped off the stack to the display, which restores the +original order that the colors were seen by the encoder. We will go thru +the first few entries in detail, which will hopefully make the process +clearer. + The first pair is (A B), so the prefix of code 6 is A and the suffix +is B, and 6 represents the string AB. The color A is sent to the display. + The 2nd pair is (B 6), so the prefix of code 7 is B and the suffix is +the the last color in the decomposition of code 6. Code 6 decomposes into +BA, so code 7 = BA, and has a suffix A. The color B is sent to the display. + The 3rd pair is (6 8) and the next code is 8. How can we decompose 8. +We know that the prefix of code 8 is 6, but we don't know the suffix. The +answer is that we use the suffix of the prefix code; A in this case since +the suffix of 6 is A. Thus, code 8 = ABA and has a suffix A. We decompose 6 +to get BA, which becomes AB when we pop it off the stack to the display. + The 4th pair is (8 B), so code 9 has a prefix of 8 and a suffix of B, +and code 9 = ABAB. We output ABA to the stack, and pop it off to the +display as ABA. + The 5th pair is (B 10) and the next code is 10. The prefix of code 10 +is B and the suffix is B (since the prefix is B). Code 10 = BB, and we +output the prefix B to the display. + The 6th pair is (10 9) and the next code is 11. Thus the prefix of +code 11 is 10 and the suffix is the last color in the decomposition of 9, +which is A. Thus code 11 = BBA, And we output BB to the display. + So far, we have output the correct colors stream A B AB ABA B BB to +the display, and have duplicated the codes 6 thru 11 in the encoder table. +This process is repeated for the whole data stream to reconstruct the +original color stream and build a table identical to the one built by the +encoder. We start the table with codes 0-5 representing the 4 colors, the +clear code, and the end code. When we get to code 8, we must increse the +code size to 5 bits, etc. See GIFDECOD.GIF for a flow diagram of the +decoding process. + +I Hope this helps take some of the mystery out of LZW compression, which is +really quite easy once you 'see' it.

raw2gif

+ +A program to convert RAW image data into GIF files. Only one image can be +handled. The RAW image file is assumed to hold one pixel color in one byte, +and therefore the file size must be Width times Height as specified by the +-s option below.

+ +

Usage:

+ +
+raw2gif [-q] -s Width Height [-p ColorMapFile] [-h] RawFile
+
+ +If no RawFile is given, Raw2Gif will try to read RAW data from stdin. +The generated GIF File is dumped to stdout.

+ +

Memory required:

+ +Line. + +

Options:

+ +
+
[-q] +
Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout + of running scan lines. Use -q- to invert.

+ +

-s Width Height +
the dimensions of the image MUST be specified in the + command line. The RAW image file size must be exactly Width times Height + bytes (each byte is one pixel color).

+ +

[-p ColorMapFile] +
Color map to load for given RAW image. This file has + 4 integers in line (ColorIndex Red Green Blue), and the ColorIndex is + in order starting from 1. See GifClrMp, which can also use/create these + bitmap files. If no color map is specified, uses the EGA 16 color pallete + as default color map.

+ +

[-h] +
Print one line of command line help, similar to Usage above.

Options:

+ +
+
[-q] +
Quiet mode. Defaulte off on MSDOS, on under UNIX. Controls printout + of running scan lines. Use -q- to invert.

+ +

[-c #Colors] +
Specifies number of colors to use, in bits per pixels, so + '-c 8' specifies actually 256 colors (maximum and default).

+ +

[-1] +
Only one file in the format of RGBRGB... triplets (Each of R, G, B + is a byte) is read from input. This file size is 3 * Width * Height (see + '-s' below. If stdin is used for input, this option is implicitly applied. + The default (if not '-1') is 3 files with the names RGBFile.R, RGBFile.G, + RGBFile.B, each of which is Width * Height bytes.

+ +

[-s Width Height] +
Specifies the size of the image to read.

+ +

[-h] +

rle2gif

+ +A program to convert images saved as RLE (Utah raster toolkit) to GIF +format.

+ +

Usage:

+ +
+rle2Gif [-q] [-c #Colors] [-h] RleFile
+
+ +If no RleFile is given, Rle2Gif will try to read an Rle file from stdin.

+ +

Memory required:

Options:

+ +
+
[-q] +
Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout + of running scan lines. Use -q- to invert.

+ +

[-c #Colors] +
Select size of color map in the output Gif file. #Colors + should be given as the based 2 log of number of colors. Default is 8 + which is 256 colors, and which is also the maximum. + +
[-h] +
Print one line of command line help, similar to Usage above..

+

+ +

Notes:

+ +As the RLE format allows full 24 bits per pixel (8 per primary color) +Colors must be quantized to the number of colors as set by the [-c] +option, above. This process is quite slow. See the quantize.c file +in the lib directory for the code for this quantization algorithm +(median cut).

text2gif

+ +A program to generate GIF images out of regular text. Text can be one line +or multi-line, and is converted using 8 by 8 fixed font.

+ +

Usage:

+ +
+text2gif [-q] [-s ClrMapSize] [-f FGClr] [-c R G B] [-t "Text"] [-h]
+
+ +This program reads stdin if no text is provided on the command line (-t), +and will dump the created GIF file to stdout.

+ +

Memory required:

+ +Line. + +

Options:

+ +
[-q] +
Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout + of running scan lines. Use -q- to invert.

+ +

[-s ClrMapSize] +
Explicitly defines the size of the color map of the + resulting gif image. Usually the image will be bicolor with fg as color + 1, unless [-f] is explicitly given in case the color map size will be + big enough to hold it. However it is sometimes convenient to set the + color map size to certain size while the fg color is small mainly so + this image may be merged with another (images must match color map size).

+ +

[-f FG] +
Select foreground index (background is always 0). By default + it is one and therefore the image result is bicolored. + if FG is set to n then color map will be created with 2^k entries where + 2^k > n for minimum k, assuming k <= 8. This color map will be all zeros + except this forground index. This option is useful if this text image + should be integrated into other image colormap using their colors.

+ +

[-c R G B] +
The color to use as the foreground color. White by default.

+ +

[-t "Text"] +
One line of text can be provided on the command + line. Note you must encapsulate the Text within quotes if it has spaces + (The quotes themselves are not treated as part of the text). If no -t + option is provided, stdin is read until end of file.

+ +

[-h] +
Print one line command line help, similar to Usage above.

+ +

Notes:

+ +There is a hardcoded limit of 100 the number of lines.

D, X, O, U - pointer to long (long *). + * 3. f - pointer to float (float *). + * 4. F - pointer to double (double *). + * 5. s - pointer to char (char *).

NO pre-allocation is needed. + * note that these two variables are pretty like the argv/argc + * pair... + * + * Examples: + * + * "Example1 i%-OneInteger!d s%-Strings!*s j%- k!-Float!f Files" + * Will match: Example1 -i 77 -s String1 String2 String3 -k 88.2 File1 File2 + * or match: Example1 -s String1 -k 88.3 -i 999 -j + * but not: Example1 -i 77 78 (option i expects one integer, k must be). + * Note the option k must exists, and that the order of the options is not + * not important.
