Description Radoslaw Szkodzinski 2007-06-27 07:01:00 UTC 
APNG support is required by current Firefox trunk and will be required for Firefox 3.

Fixing the bug means applying (and maybe forward-porting) the patch from here:

let upstream sort it out
Comment 2 SpanKY gentoo-dev 2007-06-29 12:07:09 UTC 
also, my reading of the situation is:
 - libpng guys dont want it
 - mozilla has integrated it

so a libpng with apng support would not be required for newer mozilla builds ...

Just for the record, there's http://sourceforge.net/projects/vdubapngmod/files/ where you can find latest apng patches with a mirror at http://littlesvr.ca/apng/

I'm using apng-enabled libpng ebuilds for more than a year now and never had problems. If you want to test them, just pull my overlay from rsync://gentoofan.no-ip.org/poly-c

A USE flag that would add APNG support by applying the patches would be nice. I don't think it would be difficult to do that.

well you're in luck ... i personally found a desire to have this functionality, so ive added a USE=apng flag to libpng to add support for it.
