here's a reasonably fast way to compare two images:
def compare(im1, im2):
import ImageChops
if im1.mode != im2.mode or im1.size != im2.size:
return 0
try:
return ImageChops.difference(im1, im2).getbbox() is None
except ValueError:
return im1.tostring() == im2.tostring()
I think the logical operators (which are undocumented) only work on
mode "1" images.
