# grab the pixel buffer and dump it into a numpy array
buf = fig.canvas.buffer_rgba()
l, b, w, h = fig.bbox.bounds
X = np.frombuffer(buf, np.uint8)
# The array needs to be copied, because the underlying buffer
# may be reallocated when the window is resized.
X = np.frombuffer(buf, np.uint8).copy()
X.shape = h,w,4

# now display the array X as an Axes in a new figure
