Converting between image and NumPy array

import numpy
import PIL

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

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

Saving an Image

try:, "JPEG", quality=80, optimize=True, progressive=True)
except IOError:
    PIL.ImageFile.MAXBLOCK = img.size[0] * img.size[1], "JPEG", quality=80, optimize=True, progressive=True)
