Hello all-
The recently released Firefox 3 browser (as well as Opera 9.5)
supports a new image animation format: Animated PNG, or APNG, which
has some interesting capabilities compared to animated GIFs, like 24
bit color support. The format is compatible to standard PNGs in the
sense that browsers (or other programs) that don't support APNG will
simply show its first frame (more information about APNG: http://
animatedpng.com/). It's not clear if the format will become a
standard, or which other browsers will support it, though.
I've developed an ImageJ plugin that creates APNG files from stacks
of images. It uses the japng library (
http://www.reto-hoehener.ch/
japng/) for encoding, the only Java APNG library to date I'm aware of.
The plugin can be found at

png-writer.html. Any questions, comments or suggestions are welcome.
Cheers,
Ulf
