Brought to you by the pixels 0000000000000 and 111111 This is 32 bits: 11111111111111111111111111111111 There are 32 or 64 bits in a computer 'word'. Rather than using one word for a pixel, the mask module represents 32 or 64 pixels in one word. As you can imagine, this makes things fast, and saves memory. Compute intensive things like collision detection, and computer vision benefit greatly from this. This module can also be run as a stand-alone program, excepting one or more image file names as command line arguments.
