Description Ridley Combs 2010-08-10 20:56:28 PDT
Well, PNGs are nice and all, and so is animation. So, animated PNG support would be nice!

See bug 17022 for a discussion of how this is platform specific.

For Safari, APNG support would require changes in ImageIO that are tracked as <rdar://problem/5618737>.

Big thanks to whoever implemented APNG in Safari!
Apple should make an official announcement about it.

Nitpicking now... frame blending is a little bit buggy:

It looks like we aren't blending on the Catalina or iOS 13 betas. I'll file a new bug regarding this failure.

Closing this as config changed.
