agg offers methods to convert the image pixel buffer to strings or
buffers, which you could then convert to numpy arrays, so a slice
extraction, and reconvert back to a buffer and ultimately a PNG. I
don't have time right now to write some example code, but you may want
to poke around in backend_agg to see if you can figure it out, and if
not remind me next week.
