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 *).

(? **), and will return an + * address to a block of pointers to ? kind, terminated with + * NULL pointer. 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.

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/giflib-4.1.6/Makefile.am b/giflib-4.1.6/Makefile.am new file mode 100644 index 0000000..23a12ff --- /dev/null +++ b/giflib-4.1.6/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/giflib-4.1.6/Makefile.in b/giflib-4.1.6/Makefile.in new file mode 100644 index 0000000..5d17378 --- /dev/null +++ b/giflib-4.1.6/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;

Fix a problem with header inclusion that could +prevent the library from building on some platforms. + +Version 4.1.5 +============= +This version has some important fixes for segfaults when working with corrupt +files. 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. Fix building on +several platforms. Fix x86_64 builds to not hang the encoder. + +* Fix several areas in decoding where we removed a ColorMap from our GifFile + but didn't set the pointer to NULL. This could lead to double free's of + the ColorMap. +* Fix a bug in dev2gif.c where we redefined some gl types incorrectly. +* Fix a bug in the gif LZW encoder that was triggered on modern 64 bit + platforms. +* Fix building on Windows. 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. If you had + it working with DrawText before, apologies, you'll need to change to + DrawGifText in your code. This only affects Windows. +* Add support for building on The Game Boy Advance. Note: Due to the GBA's + limited memory, the API for the GBA uses short's in many places where the + other platforms use ints. This shouldn't affect anyone unless you've + been able to get an older version of the code to run on GBA and want to + start using this version instead. 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. Use EGifPutExtension{First,Next,Last} + instead. +* Some Windows code from the old CVS repository now available in the windows + subdirectory.

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.

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.

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.

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.

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.

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.

Use + Global Color Table if available. + 1 - Local Color Table present, and to follow + immediately after this Image Descriptor. + + + + + + + + + 13 + + + vii) Interlace Flag - Indicates if the image is interlaced. 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 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. + + ix) Size of Local Color Table - If the Local Color Table Flag is + set to 1, the value in this field is used to calculate the number + of bytes contained in the Local Color Table. To determine that + actual size of the color table, raise 2 to the value of the field + + 1. This value should be 0 if there is no Local Color Table + specified.

The image data for a table based image consists of a + sequence of sub-blocks, of size at most 255 bytes each, containing an + index into the active color table, for each pixel in the image. Pixel + indices are in order of left to right and from top to bottom. Each index + must be within the range of the size of the active color table, starting + at 0.

This field contains the fixed value + 0xF9. + + iii) Block Size - Number of bytes in the block, after the Block + Size field and up to but not including the Block Terminator. This + field contains the fixed value 4. + + iv) Disposal Method - Indicates the way in which the graphic is to + be treated after being displayed. + + Values : 0 - No disposal specified. The decoder is + not required to take any action. + 1 - Do not dispose. The graphic is to be left + in place. + 2 - Restore to background color. The area used by the + graphic must be restored to the background color. + 3 - Restore to previous. The decoder is required to + restore the area overwritten by the graphic with + what was there prior to rendering the graphic. + 4-7 - To be defined. + + v) User Input Flag - Indicates whether or not user input is + expected before continuing. If the flag is set, processing will + continue when user input is entered. The nature of the User input + is determined by the application (Carriage Return, Mouse Button + Click, etc.). + + Values : 0 - User input is not expected. + 1 - User input is expected. + + When a Delay Time is used and the User Input Flag is set, + processing will continue when user input is received or when the + delay time expires, whichever occurs first. + + vi) Transparency Flag - Indicates whether a transparency index is + given in the Transparent Index field. (This field is the least + significant bit of the byte.) + + Values : 0 - Transparent Index is not given. + 1 - Transparent Index is given. + + vii) Delay Time - If not 0, this field specifies the number of + hundredths (1/100) of a second to wait before continuing with the + processing of the Data Stream. The clock starts ticking immediately + after the graphic is rendered. This field may be used in + conjunction with the User Input Flag field. + + viii) Transparency Index - The Transparency Index is such that when + encountered, the corresponding pixel of the display device is not + modified and processing goes on to the next pixel. The index is + present if and only if the Transparency Flag is set to 1. + + ix) Block Terminator - This zero-length data block marks the end of + + + + + + + + 17 + + the Graphic Control Extension. + + d. Extensions and Scope. The scope of this Extension is the graphic + rendering block that follows it; it is possible for other extensions to + be present between this block and its target. 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. The Comment Extension + may be ignored by the decoder, or it may be saved for later processing; + under no circumstances should a Comment Extension disrupt or interfere + with the processing of the Data Stream. + + This block is OPTIONAL; any number of them may appear in the Data Stream. + + b.

The end of the sequence is marked by the Block + Terminator. + + iv) Block Terminator - This zero-length data block marks the end of + the Comment Extension. + + d. Extensions and Scope. This block does not have scope. This block + cannot be modified by any extension. + + e. Recommendations. + + i) Data - This block is intended for humans. It should contain + text using the 7-bit ASCII character set. This block should + not be used to store control information for custom processing. + + ii) Position - This block may appear at any point in the Data + Stream at which a block can begin; however, it is recommended that + Comment Extensions do not interfere with Control or Data blocks; + they should be located at the beginning or at the end of the Data + Stream to the extent possible. + + +25. 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.

The data in the Plain Text Extension is assumed to be + preformatted. The selection of font and size is left to the discretion of + the decoder. 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: + +<GIF Data Stream> ::= Header <Logical Screen> <Data>* Trailer + +This rule defines the entity <GIF Data Stream> 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. + +<GIF Data Stream> ::= Header <Logical Screen> <Data>* Trailer + +<Logical Screen> ::= Logical Screen Descriptor [Global Color Table] + +<Data> ::= <Graphic Block> | + <Special-Purpose Block> + +<Graphic Block> ::= [Graphic Control Extension] <Graphic-Rendering Block> + +<Graphic-Rendering Block> ::= <Table-Based Image> | + Plain Text Extension + +<Table-Based Image> ::= Image Descriptor [Local Color Table] Image Data + +<Special-Purpose Block> ::= 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.

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**<code +size>. 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 <Clear code>+1. + +3. The first available compression code value is <Clear code>+2. + +4. The output codes are of variable length, starting at <code size>+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.

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.</P> + +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.<P> + +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.<P> + +This library speaks both GIF87a and GIF89.

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.
