You probably need to look up "image cropping" for PIL, look at this answer: http://stackoverflow.com/a/9983361/532471 — Geekfish, Mar 18 '13 at 10:59

img = Image.open('your_wonderful_image.png')
nonwhite_positions = [(x,y) for x in range(img.size[0]) for y in range(img.size[1]) if img.getdata()[x+y*img.size[0]] != (255,255,255)]
rect = (min([x for x,y in nonwhite_positions]), min([y for x,y in nonwhite_positions]), max([x for x,y in nonwhite_positions]), max([y for x,y in nonwhite_positions]))
img.crop(rect).save('out.png')
