in thread editing gifs with Perl
PNG is very similar to GIF, but it uses a different compression algorithm and can't be animated (yet, I hear rumors that they are working on that...)
The PNG equivalent of Animated GIFs are MNGs (Multiple-image Network Graphics.) As implied by the name, MNG was based on the PNG format to handle animated graphics. In addition to sharing a number of PNG's best features, it offers the following animation features:
- Object/sprite based animation
- Much better compression than animated GIFs
- Frame differencing support
- Nested loops (useful for complex animations)
