Wanted: developer for giflib-4.2 and beyond

There has been some recent interest in seeing more features added to giflib. This is something that I don't personally have time for but would be happy to turn over the reigns to someone that wants to drive giflib development forward. Please contact the giflib-devel mailing list (prefered) or me directly to get involved!

giflib-4.1.6

A brown paper bag issue that could cause builds to fail on some platforms was discovered. 4.1.6 includes changes to header inclusion in two files that should fix this.

libungif development stopped

Work on libungif has been halted due to the expiration of the patent on LZW. giflib continues to have bugfixes and patches merged. As part of this work, the sourceforge project has been renamed from libungif to giflib.

If you have a need for libungif itself, please send a note to the giflib maintainers so you can be added to the project to maintain that branch.

giflib 4.1.4 and libungif 4.1.4

giflib and libungif 4.1.4 have now been released. This is a minor bugfix for libungif and a rather major one for giflib that allows proper operation on x86_64 systems.

Also new for this release, project files have moved into sourceforge cvs to allow better coordination with additional developers.

SVN repository back online

Those of you watching the libungif subversion repository may have noticed it was inaccessible this weekend. I recently updated apache there and it seems it has been consuming excess memory until it gets oom_killed by the linux kernel. I've restarted the http server with a few less modules and a few less threads for now but haven't tracked the root cause down. I'll be working on that tonight when there are less people looking to access the repository.

Subversion repository

For those who may be interersted in joining the development of libungif and giflib, I've moved my subversion repository to a publically accessible server. this is sitting in my house in Vermont, which is subject to summer thunderstorms so reliability then is not assured. Still, it'll have to do until sourceforge gets subversion cpability.

giflib 4.1.3 now on sourceforge

giflib is a library for reading and writing GIF files. The 4.1.3 Release is a general cleanup of bugs and hard to read code. It syncs with the 4.1.3 release of libungif and should provide programmers with an API and ABI compatible replacement for that library.

giflib is able to read and write all GIF files using the LZW algorithm patented by UniSys. Although this patent has expired in the United States, patent searches by the FSF show that worldwide patents exist until 2006. If you must have a patent free version of the library, please look into libungif as a suitable replacement.

If you are using giflib on MS Windows, you may be interested in the code in the windows subdirectory provided by Lennie Araki under the same terms as the giflib library. Unfortunately, I do not have a Windows environment to maintain this code. If anyone wants to keep it functional, patches and maintainers are welcome.

libungif 4.1.3 released

libungif is a library for reading and writing GIF files. The 4.1.3 Release is a cleanup of bugs in the Extension Handling Code. In particular, if you had issues when using multiple subblocks for an Extension or longer than normal comments, this release should fix it.

libungif is able to read and manipulate all GIF files. However, it only writes uncompressed GIFs which do not use the LZW algorithm patented by UniSys. Although this patent has expired in the United States, patent searches by the FSF show that worldwide patents exist until 2006. By not including LZW compression libungif is freely redistributable throughout the world.

That said, 4.1.3 of giflib, a GIF manipulating library that supports LZW compression is being released concurrently with this release of libungif. If you live in a country where the UniSys patent has expired you may consider using that instead. Please get giflib from the sourceforge site where you found libungif.

If you are using libungif on MS Windows, you may be interested in the code in the windows subdirectory provided by Lennie Araki under the same terms as the libungif library. Unfortunately, I do not have a Windows environment to maintain this code. If anyone wants to keep it functional, patches and developers are welcome.

libungif 4.1.2 released

libungif is a library for reading and writing GIF files. The 4.1.2 Release
is a cleanup of long standing bugs in the code. If you have issues with
older releases of the library, please try this updated version.

libungif is able to read and manipulate all GIF files. However, it only writes
uncompressed GIFs which do not use the LZW algorithm patented by UniSys.
Although this patent has expired in the United States, patent searches by the
FSF show that worldwide patents exist until 2006. By not including LZW
compression libungif is freely redistributable throughout the world.

Since the release of libungif 4.1.1 I have been auditing the libungif source
to get rid of compiler warnings, make things more readable, and eliminate long
standing bugs in the source code. The library portion of the code is complete
in this regard. The 4.1.3 releases will concentrate on fixing any new reported
bugs, merging some Windows utilities that were in the old libungif CVS tree,
and cleaning up the coding style in the utilities.

First libungif 4.1.2 beta released

libungif is a library for reading and writing GIF files. The 4.1.2 Beta Series concentrates on cleaning up long standing bugs and cruft in the source code.

New test release 4.1.0b2

New release 4.1.0b2 is the newest on the road to 4.1.1. It resolves several flaws in the 4.1.0b1 release. One more issue is scheduled for completion before the 4.1.1 release. But there are already many more that need to be looked into before 4.1.2.
