Rotate Gif with bug

Post by tiagoferezin » 2019-04-17T10:16:39-07:00

I am running the command in linux
convert -background none -rotate 60 -limit memory 0 input.gif output.gif
and the return of the gif I have is the one below:

This is my output.gif, and below my input.gif

What happens and how do I fix this problem?

GIF optimization removes parts of the frames to optimize. So you need to coalesce your frames to fill them out to the same size. Then at the end re-optimize. Also in ImageMagick 6 and 7, you need to put the input image first. This works for me on IM 6.9.10.40 Q16 Mac OSX.

Code: Select all

convert bunny.gif -coalesce -background none -rotate 60 -layers optimize newbunny.gif
Please always provide your IM version and platform when asking questions.
