This is what I've used. I started with: http://effbot.org/zone/pil-numpy.htm which uses the old numeric package, and modified it slightly for numpy, so it looks like: import numpy, Image def image2array(im): if im.mode not in ("L", "F"): raise ValueError, "can only convert single-layer images" if im.mode == "L": a = numpy.fromstring(im.tostring(), numpy.UInt8) else: a = numpy.fromstring(im.tostring(), numpy.Float32) a.shape = im.size[1], im.size[0] return a def array2image(a): if a.dtype.name == 'uint8': mode = "L" elif a.dtype.name == 'float32': mode = "F" elif a.dtype.name == 'float64': a=a.astype('float32') mode = "F" else: raise ValueError, "unsupported image mode %s" % a.dtype.name return Image.fromstring(mode, (a.shape[1], a.shape[0]), a.tostring()) seems to work! bb -- ----------------- [EMAIL PROTECTED] http://web.bryant.edu/~bblais _______________________________________________ Image-SIG maillist - Image-SIG@python.org http://mail.python.org/mailman/listinfo/image-sig
