There's a brief note here:
http://effbot.org/zone/pil-extending.htm
You can simplify the dependencies by simply copying the Imaging
definition to your own code -- the "im.id" attribute used in that
article is guaranteed to give you a pointer to that structure (that
is, if the structure ever changes, PIL will provide a different
mechanism to access the internal image descriptor).
Another approach is to use tostring/fromstring in a wrapper, and write
a C extension that works on a byte string or buffer object.
