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.
