How to convert a PIL Image into a numpy array?

Alright, I\'m toying around with converting a PIL image object back and forth to a numpy array so I can do some faster pixel by pixel transformations than PIL\'s Pixel

You need to convert your image to a numpy array this way:

import numpy
import PIL

img = PIL.Image.open("foo.jpg").convert("L")
imgarr = numpy.array(img)
