<para>The reason <application>libungif</application> only writes non-compressed

<acronym>GIF</acronym>s is due to a legal issue with <acronym>LZW</acronym>
|

compression (which Unisys claimed a patent on). Reading <acronym>GIF</acronym>s
|
||||
is not a problem as the decompression 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 <application>libungif</application> for
|

looking at <acronym>GIF</acronym> images on the web, while in any pages which
|
||||
you design, use the open source <acronym>PNG</acronym> format instead (which

uses, not surprisingly, the <application>libpng</application> library) which
