I'm no expert, but probably a string that's the same format as what tostring_argb() returns, so something like this should work (untested!): buffer = self.get_renderer().tostring_argb() l, h = self.GetSize() matrix = numpy.fromstring(buffer, dtype=numpy.byte) matrix.shape = (l,h,4) # 4 for a,r,g,b sub_matrix = matrix[min_x:max_x, min:y_max_y, :] r.draw_image (0, 0, sub_matrix.tostring()) -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [EMAIL PROTECTED] ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
