#1825 closed task (fixed)

Update of libungif sources to giflib

Reported by: Mateusz Łoskot Owned by: Even Rouault
Priority: normal Milestone: 1.7.0
Component: GDAL_Raster Version: svn-trunk
Severity: normal Keywords: gif libungif png zlib
Cc: warmerdam

Description (last modified by warmerdam)

The goal of this task is to update sources of some included libraries including libungif library used by trunk/gdal/frmts/gif driver. Also, consider use of the libgif (instead of libungif) library if we can conclude that the GIF patent threat has passed.

This ticket is related to #1818.

Other libraries to consider updating are zlib, and libpng.

Target for post 1.5 release (in the 1.6 tree) rather than disrupt 1.5 since there is no apparent pressing rush.

The consequence of the update to giflib is that GIF files produced by internal giflib are now LZW compressed (doc updated in r16860). The patent issue has been solved for a long time : Debian ships giflib since 2004, and all major Linux distributions also do.
