Perhaps
canvas = gcf().canvas
buf = canvas.tostring_rgb()
img = numpy.fromstring(buf, numpy.uint8)
im_size = canvas.get_width_height()
rgb = img.reshape(im_size[1], im_size[0], 3)
r, g, b = rgb[:,:,0], rgb[:,:,1], rgb[:,:,2]
Or if you're using PIL,
pil_image = PIL.Image.fromstring("RGB", im_size, buf)

Hi,
I want to convert the current figure to a numpy array w/o saving the
image to disk. I need this to convert a matlab function to python, the
original code is:
F = getframe(gcf);
X = frame2im(F);
My current workaround is
h = gcf()
h.savefig('tmp.pn
