Python: Converting GIF frames to PNG
I don't think you're doing anything wrong. See a similar issue here: animated GIF problem. It appears as if the palette information isn't correctly treated for later frames. The following works for me:
def iter_frames(im):
try:
i= 0
while 1:
im.seek(i)
imframe = im.copy()
if i == 0:
palette = imframe.getpalette()
else:
imframe.putpalette(palette)
yield imframe
i += 1
except EOFError:
pass
for i, frame in enumerate(iter_frames(im)):
frame.save('test%d.png' % i,**frame.info)
I've fixed this bug here https://code.launchpad.net/~asdfghjkl-deactivatedaccount1/python-imaging/gif-fix.
DSM's answer won't work if the GIF uses local color tables.
