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.
