About

Unfortunately the new compression method implemented in gd1.3 is not as good as the old "LZW" compression method used gd1.2. The new GIF files are now usually twice as big.

LZW compression had to be removed due to UNISYS and IBM's patent rights on LZW. For more information check out the gd1.3 site, the GIF information provided by the GNU foundation and what UNISYS has to say about LZW and GIF.

If you need smaller GIF file than you get with gxgif + gd1.3 consult UNISYS, IBM and/or your lawy er if you can use LZW for GIFs without being sued. If you feel you can, get gd1.2 and compile gxgif.c with it.
