[Image-SIG] bounce animation of an image

2009-08-03 Thread Astan Chee
Hi, I have a script that takes an image and makes it looks like it bounces. Here it is: import Image def saveImg(p,pos): im = Image.open(new_logo.jpg) name = new_logo. + str(p).zfill(4) + .jpg om = Image.new(im.mode,(im.size[0],im.size[1])) box = (0,pos,im.size[0],im.size[1])
