Frame loss in GIF

[ghost]

What did you do?

I try to extract frame from a gif

What did you expect to happen?

I expect to get png or jpg image.

What actually happened?

I got the same gif but in other mode.

What are your OS, Python and Pillow versions?

• OS: Windows
• Python: 3.10.1
• Pillow: 9.0.0

Hi.

Since Pillow 9.0 / #5857, once you seek past the first GIF frame, the mode will change to RGB or RGBA, yes. This is because P mode can only handle up to 256 colors, and once you go past the first frame, there may be more colors than that.

The fact that avatar is a GifImageFile instance reflects the fact that you opened a GIF. I highly doubt that you actually need avatar to be a PngImageFile or JpegImageFile instance to accomplish your goal. If you think otherwise, please provide some more comments and we can discuss this further.

If you would like to create a PNG or JPG from your GIF, you can just run avatar.save("out.jpg") or avatar.save("out.png").
