Converting a matrix into an image in Python

Question

I would like to save a numpy matrix as a .png image, but I cannot do so using the matplotlib since I would like to retain its original size (which apperently the matplotlib doesn't do so since it adds the scale and white background etc). Anyone knows how I can go around this problem using numpy or the PIL please? Thanks

see `fig.figimage` http://matplotlib.org/api/figure_api.html#matplotlib.figure.Figure.figimage — tacaswell, Apr 14 '16 at 15:35

Solved using scipy library

import scipy.misc

...(code)

scipy.misc.imsave(name,array,format)

or

scipy.misc.imsave('name.ext',array) where ext is the extension and hence determines the format at which the image will be stored.
