Return a copy of a PIL image as a numpy array.
Parameters
----------
im : PIL image
Input image.
flatten : bool
If true, convert the output to grey-scale.
Returns

fromimage : ndarray
The different colour bands/channels are stored in the
third dimension, such that a grey-image is MxN, an
RGB-image MxNx3 and an RGBA-image MxNx4.
