Gifsicle is a UNIX command-line tool for creating, editing,
|
|
and getting information about GIF images and animations.
|
|
You can also extract frames from animations, or replace, delete,
|
|
or insert frames into existing animations.
|
|
Some more gifsicle features:
|
|
* Batch mode for changing GIFs in place.
|
|
* Prints detailed information about GIFs, including comments.
|
|
* Control over interlacing, comments, looping, transparency...
|
|
* Creates well-behaved GIFs: removes redundant colors, only uses
|
|
local color tables if it absolutely has to (local color tables
|
|
waste space and can cause viewing artifacts), etc.
|
|
* It can shrink colormaps and change images to use the Web-safe
|
|
palette (or any colormap you choose).
|
|
* It can optimize your animations! This stores only the changed
|
|
portion of each frame, and can radically shrink your GIFs. You can
|
|
also use transparency to make them even smaller. Gifsicle's
|
|
optimizer is pretty powerful, and usually reduces animations to
|
|
within a couple bytes of the best commercial optimizers.
|
|
* Unoptimizing animations, which makes them easier to edit.
|
|
|
|
Two other programs are included with gifsicle: gifview is a
|
|
lightweight animated-GIF viewer which can show animations
|
|
as slideshows or in real time, and gifdiff compares two GIFs
|
|
for identical visual appearance.
