GIF split into frames saves corrupted png images

[noambaron1989]

I'm trying to split gif into frames and save as PNG.
The issue is, some gifs are low quality and when getting to the second frame onwards, the frames are corrupted.

this is the code I'm using:

import logging
import os

from PIL import Image
from logger import Logger

toddler_lq = '/Users/noambaron/Downloads/toddler_LQ.gif'
toddler_dir = '/Users/noambaron/Desktop/toddler_f'
gif_path = toddler_lq
frame_dir = toddler_dir
logger = Logger(logging.INFO, 'gif_test')

try:
    frame = Image.open(gif_path)
    palette = frame.palette
    num_of_frames = 0
    while frame:
        base_name = os.path.basename(gif_path).split('.')[0]
        frame.show()
        frame.save(os.path.join(frame_dir, '%s-%s.png' % (base_name, num_of_frames)), 'PNG')
        num_of_frames += 1
        try:
            frame.seek(num_of_frames)
        except EOFError:
            break
except Exception as e:
    logger.error('failed extracting frames from gif %s due to %s', gif_path, e)

attached is the gif, and the 3 first frames

I have the same issue with similar code:

import PIL
from PIL import Image
from PIL import ImageOps
from PIL import GifImagePlugin

gif = Image.open('/home/pi/Photos/ANIMATION.gif')

# for frame in ImageSequence.Iterator(gif):
for n in range(0,gif.n_frames):
    gif.seek(n)
    im = ImageOps.grayscale(gif)
    im.save("/home/pi/Photos/tmp/gif_{}.bmp".format(n))

@peterableda please open a new issue with your specific image.

Pillow 9.0.0 has significantly improved reading animated GIFs thanks to #5857.
