Check type of image input

[Hammy27]

Usecase: I use your wrapper for on the fly profile-picture processing (make a thumbnail of users face while at the same time making sure they only upload images with a face on it) in Django. I therefore pass the image as a numpy array.

Problem: If one does not provide the array as a PIL Image array colors are kind of inverted.

Solution: I post-process the resulting image with an inverse version of your gbr_to_rgb function.

Request: please check the type of the input array and let it decide if color-reversion has to be applied.

could you provide more details about your solution? Did you convert image input in gbr_to_rgb function as PIL Image array before converting to RGB?
