I would like to make a numarray array that shares data with a Numeric array and/or with a PIL Image. As an example of the sort of thing I want to do:

...

...

import Numeric, Image, ImageDraw a = Numeric.zeros((8,8), 'b') im = Image.frombuffer('L', a.shape[::-1], a) im.readonly = False d = ImageDraw.Draw(im) d.line((0,0,8,8), fill=255) a array([[ 0, 0, 0, 0, 0, 0, 0, 255], [ 0, 0, 0, 0, 0, 0, 255, 0], [ 0, 0, 0, 0, 0, 255, 0, 0], [ 0, 0, 0, 0, 255, 0, 0, 0], [ 0, 0, 0, 255, 0, 0, 0, 0], [ 0, 0, 255, 0, 0, 0, 0, 0], [ 0, 255, 0, 0, 0, 0, 0, 0], [255, 0, 0, 0, 0, 0, 0, 0]],'b')

So with Numeric, I can have bidirectional data sharing between an array and an Image object. I have been unable to do the same using a numarray array. Does anyone know whether there is a way to do this? Chris Perkins
