"Resolution" is a too much overloaded word, from some point of view increasing the resolution of images is a very difficult thing, that may need deblurring, etc. So let's talk in a simpler way, about the len of the sides of the image measured in pixels. To increase such len, you can use PIL library, the resize method from image: http://www.pythonware.com/library/pil/handbook/image.htm This is some example code: from PIL import Image im = Image.open("1.jpg") nx, ny = im.size im2 = im.resize((int(nx*1.5), int(ny*1.5)), Image.BICUBIC) im2.save("2.png") Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
