Using PIL and `im.crop(box)` usually works, see http://www.pythonware.com/library/pil/handbook/introduction.htm can you post some more code that showcase what you are doing? — Fredrik Pihl, Jun 27 '11 at 17:13

from PIL import Image
im = Image.open("test.jpg")

crop_rectangle = (50, 50, 200, 200)
cropped_im = im.crop(crop_rectangle)

cropped_im.show()

Note that the crop region must be given as a 4-tuple - (left, upper, right, lower).

I did exactly that, but the answer is: "'Numpy.ndarray' object has no attribut 'crop'. that's my doubt. What do i do now? – Carlos Pinto da Silva Neto Jun 30 '11 at 11:44
That means you are trying to apply a crop method to a Numpy.ndarray instance but it doesn't have a crop method. Make sure you are applying the crop method to an instance of PIL's Image class. If you still can't get it working, post your code. – symmetry Jun 30 '11 at 16:59
