| Note: to change the version, you have to hack both Makefile and lib/Makefile. |
| |
| Version 3.0: |
| ------------ |
| |
| New features: |
| * Incorporated Sirtaj Kang's changes to make both static and shared libs. |
| * All the utility and library docs are HTML now. |
| * The library and relevant utilities are now fully GIF89-aware. |
| * Functions for drawing text and boxes on saved images are documented. |
| * The distribution is now issued under a simple X-Consortium-style license. |
| * Can now generate package RPMs and LSM automatically. |
| * Home page with Web-acessible documentation at http://www.ccil.org/~esr/giflib |
| |
| Bug fixes: |
| * Fix giftext to not core dump on a null extension record. |
| * Incorporate Philip VanBaren's change to prevent a core dump in gifasm. |
| |
| Version 2.3: |
| ------------- |
| 1. Fixed a core-dump bug in gifcomb revealed by the ELF environment in Linux |
| 1.2.13. |
| |
| Version 2.2b: |
| ------------ |
| 1. Added gifburst tool. |
| |
| Version 2.2 |
| ----------- |
| 1. Linux is supported. |
| |
| Version 2.1 |
| ----------- |
| 1. Added the gifovly tool, which supports making a composite from several GIF |
| images. |
| |
| 2. Used gifovly to implement a full-fledged pasteup program in shell. It's |
| called gifcompose and lives in the util directory. |
| |
| 3. Added a copy of the GIF89 standard to the doc directory (gif89.txt); |
| also a description of the preferred compression method (lzgif.txt). |
| |
| Version 2.0 |
| ----------- |
| With this version, development was taken over from Gershon Elber by Eric |
| S. Raymond <esr@snark.thyrsus.com>. Note that I, esr, have pretty much |
| adhered to Gershon's coding style, even though it's quite baroque and DOS- |
| headed by my standards. |
| |
| Library Improvements |
| |
| 1. New DGifSlurp() and EGifSpew() library entry points allow all GIF-bashing |
| to be done in core on machines with sufficient memory. Writing code to |
| slice'n'dice multiple GIFs in non-sequential ways is now much easier (send |
| kudos and brickbats to esr, small unmarked bills preferred). |
| |
| 2. The interface has changed somewhat. Members in the GifFileType structure |
| have been renamed and regrouped. This was required for support of the |
| SavedImages member (which enables the new functions mentioned in 1). Also, |
| there is a new data type for allocated color maps and routines to handle |
| it conveniently. |
| |
| 3. Some minor bugs have been fixed. Most notably, the DGif code now correctly |
| handles the possibility of more than one code block per extension record, |
| as per the GIF spec. 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 assembles named |
| GIFs with editable text color map & icon raster representations to produce |
| multi-image GIFs usable as graphical resource files. 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. The documentation has been overhauled completely and translated out of the |
| dialect spoken by the estimable Mr. Elber into something like standard |
| English :-). |
| |
| 9. 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. Read the comments in them |
| for more info. |
| |
| 10. The util Makefile for UNIX has been improved. It now uses the cc/gcc -s |
| option rather than strip(1). There are now separate install productions, |
| so you can test new versions in util before installation for production |
| (the top-level make script still does an install). |
| |
| |
| Version 1.2 |
| ----------- |
| 1. GIFFIX - a new tool to attempt and fix broken GIF images. Currently fix |
| images that has EOF prematurely by padding with the darkest color. |
| 2. Make GIF2BGI display as much as it can considering the mem. avail. |
| 3. Add -q flag to all tools for quite running scan line number mode. |
| 4. Fix a (minor!?) bug in the GIF decoder when encountering code 4095. |
| 5. New tools (RGB2GIF and GIF2RGB) to convert GIF to/from 24 bits RGB images. |
| 6. New tool GIFROTAT to rotate a gif image by an arbitrary angle. |
| 7. GifRSize was updated to resize by an arbitrary factor. |
| |
| Version 1.1 |
| ----------- |
| 1. GIF2BGI - a new utility to display GIF images using Borland's BGI drivers |
| (if you have one...) |
| 2. TEXT2GIF - Converts plain text into GIF images. |
| 3. GIF2IRIS - SGI4D display program for GIF images. |
| 4. GIF_LIB naming convension has been modified to make sure it has unique |
| names (see gif_lib.h). |
| 5. Support for SGI4D gl and X11 window grabbing has been added to the |
| library. SGI4D input is quantizied into 8 bits. |
| Also support for EGA/VGA devices has been added as well. |
| see Dev2gif.c module. |
| 6. Support for the new gif89a format has been added. |
| |
| Enjoy, |
