I'm looking for a Python3-compatible way to sort a list of PIL image objects based on a computed difference between the two images. In 2.x, this would work:
imagelist.sort(cmp=image_diff(a,b))
Maybe this could be done by creating a new class with the appropriate __lt__,
____gt__, __eq__ methods, but that seems like more work than should be
necessary. Any suggestions?
