A Filter I use in some scripts to find the transparent color used
in GIF files being decoded. Also useful to add transparency, interlace
or just check the content of GIF images, inside and outside image
scripts. WARNING: I have found and corrected a few bugs in giftrans,
look for the fixed version in my
ftp area (v1.12.3)
Other GIF handling programs are now available, including...
- transgif -- a simple perl GIF transparency setting script
- Gifsicle -- a GIF animation and optimizer handler. It can take
a existing gif animation and optimise the animation frames for the
- ImageMagick is also extremly good, in fact I based my ".anim"
animation control files on the command line options of it. It is a
shame the "identify" command does not provide the detail I need.
