It looks like it might be using numpy.

If 'im' is a numpy array representing an image, then its .shape
attribute is giving its 'shape' (a tuple of the sizes of its

numpy.zeros(...) will when return a numpy array of the same shape.

So, it's not setting the image pixels to 0, but creating a new image of
the same shape in which the pixels are 0.
