if "array" refers to Python list, this question should really have been sent to a general
python forum, and the answer is found here:

if "array" refers to a Numpy array, you may have better luck by asking on a Numpy
support forum.

if "array" refers to a PIL image memory, the answer is "you cannot do that".
