help

help(img.crop)

Help on method crop in module PIL.Image:

crop(box=None) method of PIL.PngImagePlugin.PngImageFile instance
    Returns a rectangular region from this image. The box is a
    4-tuple defining the left, upper, right, and lower pixel
    coordinate.
    
    Note: Prior to Pillow 3.4.0, this was a lazy operation.
    
    :param box: The crop rectangle, as a (left, upper, right, lower)-tuple.
    :rtype: :py:class:`~PIL.Image.Image`
    :returns: An :py:class:`~PIL.Image.Image` object.
