Python resizing animated gif with PIL

Question

I follow the step at Resize GIF animation, pil/imagemagick, python to resize image using PIL and image2gif . However, I got the resized gif washed out like below:

How do I solve this problem?

Answer 1

I have not tried this, but this suggests that the way to maintain transparency in GIF images with PIL when saving is:

im = Image.open(...)
transparency = im.info["transparency"]
...
out.save("out.gif", transparency=transparency)
