Why you said that the string are invalid? --code: test_image_double.py from urllib import urlopen import Image from ImageFile import Parser def double(image_data): image_parser = Parser() image_parser.feed(image_data) im = image_parser.close() new_size = tuple(map(lambda x: 2 * x, im.size)) new = im.resize(new_size) return new.tostring("gif", "P"), new, new_size url = "http://www.google.com/intl/en_ALL/images/logo.gif" image_data = urlopen(url).read() image_data, img, new_size = double(image_data) img_new = Image.fromstring("P", new_size, image_data, "gif") img_new.save("./out1.gif") img.save("./out2.gif") print "PIL version:", Image.VERSION -- test michele:~/tmp$ python test_image_double.py && file out1.gif && file out2.gif (552, 220) 49554 PIL version: 1.1.5 out1.gif: GIF image data, version 87a, 552 x 220 out2.gif: GIF image data, version 87a, 552 x 220 michele:~/tmp$ > Any ideas? > Forgot to specify that the data aren't in raw format, but to decode it with the "gif" encoder? > Thanks, Ciao, Michele -- http://mail.python.org/mailman/listinfo/python-list
