How to convert between NumPy array and PIL Image

Converting a single channel PIL Image to a 1-D NumPy array and back is easy:

import numpy
import PIL

# Convert Image to array
img = PIL.Image.open("foo.jpg").convert("L")
arr = numpy.array(img)

# Convert array to Image
img = PIL.Image.fromarray(arr)

Tried with: Python 2.7.3 and Ubuntu 12.04
