Black background on frames after first frame in GIF using Pillow

[AnasYasin]

What did you do?

I am trying to place a gif on png using Pillow. It's giving black background after the first frame. I have tried every solution on Github including #1987 and #1976

What did you expect to happen?

It should make a transparent GIF place on a png.

What actually happened?

Currently, all frames after the first frame are having a black background. The code is working file on small GIFs.

Orignal Gif:

Background Image:

Final Result:

Frames:

What are your OS, Python and Pillow versions?

• OS: Linux Mint 19.1 x86_64
• Python: 3.6.8
• Pillow: 8.2.0

from PIL import Image, ImageSequence

gif = Image.open("gif4.GIF")
duration = 100
disposal = 2
frames = []
ind = 0

for frame in ImageSequence.Iterator(gif):
    bg2 = Image.open('test1.png')
    bg2.paste(frame, frame.convert('RGBA'))
    bg2.save('{}.png'.format(ind))
    frames.append(bg2)
    ind  += 1
    
frames[0].save('test.gif', save_all=True, append_images=frames[1:], loop=0, optimise=False, duration=duration, disposal=disposal, format='GIF')

If you simplify your code to just reading and saving your GIF,

from PIL import Image, ImageSequence

gif = Image.open("gif4.GIF")
ind = 0

for frame in ImageSequence.Iterator(gif):
    frame.save('{}.png'.format(ind))
    ind  += 1

you will see that the colours are still not correct. I expect this is part of a long standing bug where Pillow doesn't correctly read the colours from different palettes after the first GIF frame. See #3735 for a longer explanation.

Yes, I am stuck on this for a week now. I on read an issue that this bug has been resolved in 8.1 but I'm still having this problem. Can you suggest any other library of way-out to get this done in Python?
Thanks.

Good news: I was wrong. This was not our long standing bug, but is instead the same as #5656, fixed by #5756. Your code will work correctly in Pillow 8.4.0.

Extra good news: Pillow 8.4.0 is due to be released in two days.

Pillow 8.4.0 has been released on PyPI. So if you upgrade, this should now work for you.

I am having this issue on 8.4.0

print(frames)

frames[0].save('images/generated/output.gif', save_all=True, append_images=frames[1:], loop=0)
