I'm assuming you're using the Agg backend. If so, you can get the raw memory wrapped in a Python buffer object as follows: figureCanvas.get_renderer().buffer_rgba(x, y) (where x, y is the upper left corner in the plot of the area you want to get.) It should be possible in C side to then get the address out of that using the Python/C API.
