Creates an image memory from an object exporting the array interface
(using the buffer protocol).
If obj is not contiguous, then the tobytes method is called
If **obj** is not contiguous, then the tobytes method is called
and :py:func:`~PIL.Image.frombuffer` is used.
If you have an image in NumPy::
from PIL import Image
import numpy as np
im = Image.open('hopper.jpg')
a = numpy.asarray(im)
Then this can be used to convert it to a Pillow image::
im = Image.fromarray(a)
:param obj: Object with array interface
:param mode: Mode to use (will be determined from type if None)
