Re: Resizing certain GIFs produces incorrect output

Interesting: using the same arguments you suggested with mogrify results in the same bug as frames having the unresized offset, but convert works. I'm using Ubuntu 14.04 BTW, and Version: ImageMagick 6.7.7-10 2014-03-06 Q16

Re: Resizing certain GIFs produces incorrect output

Hm, that does indeed work, thanks! It still does increase the size by about 35% in my particular test case if it's the same size, but it's still worth it when resampling to half the width

Re: Resizing certain GIFs produces incorrect output

Doesn't -coalesce remove the offset optimization? That defeats the purpose of resampling (reducing bandwidth usage), and IIRC, didn't work completely either.

Resizing certain GIFs produces incorrect output

Resizing GIFs where each frame is the size of the whole gif works fine. However, if frames are smaller and have an offset, the offset is not resized, such that these frames appear in the wrong place. I'd be happy for my team to work on this if I could get some direction on where the bug probably is ...
