<para>The libungif package contains libraries for reading all gifs and
|
||
|
|
writing uncompressed ones as well as programs for converting and working
|
||
|
|
with gif files. The libraries are useful for any graphics program
|
||
|
|
wishing to deal with gif files while the programs are useful for
|
||
|
|
conversion purposes as well as cleaning up images.</para>
|
||
|
|
|
||
|
|
<para>The reason libungif only writes uncompressed gifs is due to a
|
||
|
|
legal issue with LZW compression (which Unisys claims a patent on).
|
||
|
|
Reading gifs is not a problem as the uncompression routines do not seem
|
||
|
|
to be limited in this way. Note that this has in the past been
|
||
|
|
disputed. The best way to avoid this whole mess is to simply use
|
||
|
|
libungif for looking at gif images on the web, whilst in any pages which
|
||
|
|
you design, use the open source png format instead (which uses, not
|
||
|
|
surprisingly, the libpng library) which has no patent issues at
|
||
|
|
all.</para>
