PIL altrenatives?

[Max Khesin]

I am looking for a python func to do edge detection. A good function would
be a version of im.point(func), where func would be passed the pixel's
neighbourhood, so that different edges can be produced. As far as I can tell
PIL does not support this directly. Of course, this could probably be done
with PIL the long way, by getting individual pixels. But are there
alternatives? Also, is there a good source for PIL code samples?

thanks,
