gif2h.py: line 74 TypeError: list indices must be integers or slices, not tuple about scintillating_heatshrink

I've deleted the VM now, but I was definitely using Python 3. apt install python3-pil pulled in a compatible version of PIL 9.x.x.

Thanks for the report. I've just tried to convert a GIF on my system, and I received the same error. I guess things have changed in Python 3.10.12 compared to whatever version I was using 3 years ago . I'll try to find time to look at this later today.

Argh! This is turning into a nightmare for a Python newbie like me, who hasn't really touched Python in the last 3 years. My code was written using the PIL library which is now deprecated. Modern Ubuntu uses the Pillow library, which is meant to be compatible.

The root of the problem is that PIL used to return the palette index for each pixel in each frame. Pillow does the same for the first frame of animation, but then every subsequent frame it returns RGB triplets instead. I can't find a way to get the palette indices for frames 1+ out of Pillow. I guess this change was made as a bug fix because animated GIFs can actually store more than 256 colours.

This is going to require significant changes to gif2h.py, so don't hold your breath for a fix.

I just created an Ubuntu 20.04 virtual machine. The code still works correctly in that. You could do that, or email me your GIFs I'll convert them for you. mailto:[email protected]

I think I'll do the same.
On Ubuntu 20, is it working with Python2 or 3 ?
Which version of PIL is successfull ?

this command can show PIL version
import PIL
PIL.version
