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
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.
