Hi, What is the best way to rasterize a figure into a numpy array for further image processing? The code I have below works, but I am wondering if there is a more convenient way. Thanks in advance, Geoff import pylab, numpy fig = pylab.figure() pylab.plot( [1, 2, 1] ) dpi = fig.get_dpi() size = fig.get_size_inches() shape = size[1] * dpi, size[0] * dpi, 3 image = fig.canvas.renderer.tostring_rgb() image = numpy.fromstring( image, 'u1' ).reshape( shape ) pylab.imshow( image )
