Anti-aliasing on gif animation
hi everyone,

Well this might look advanced but i'm only a beginner at gimp so here goes:

I created this Gif animation with GIMP using Blender to provide the frames. The end result looks like this:

Gif animation here

The question is:
How to put anti-aliasing on the frames so it won't look as jagged?

Thnx in advance,

Reskaillev

EDIT: do the newer versions of GIMP provide PNG animation support? Is it planned?

RE: Anti-aliasing on gif animation
The problem with GIF is that anti-aliasing that works on all backgrounds requires partial transparency which is not supported by the GIF format. If the GIF image is going to be displayed on a specific background, you can use Layer/Transparency/Semi-flatten after setting the background color accordingly to replace partial transparency by the equivalent foreground/background transition. But then your image won't be usable on another background.

For APNG support see here: http://registry.gimp.org/node/24394
