Currently I\'m using a pixel reader via AutoItv3 to perform some actions in a program that is running direct X; A game. Right now the program works fine but as an exercise

It's an old question, but it ranks quite highly on Google when searching for Python screen grab methods, so I think it might be useful to mention that the ImageGrab module now supports grabbing a region of the screen:

PIL.ImageGrab.grab(bbox=None)
Parameters: bbox – What region to copy. Default is the entire screen.
Returns:    An image

Expanding the scope slightly, there is now also a replacement for ImageGrab called pyscreenshot, that also saves some part of the screen to a or PIL/Pillow image. This module also works on Linux, unlike ImageGrab which is Windows and OS X only.

import pyscreenshot as ImageGrab
im=ImageGrab.grab(bbox=(10,10,510,510)) # X1,Y1,X2,Y2
im.show()
