title: programmatically edit images for puzzle usage
body: <p>I'm making a sliding puzzle ( 3x3/4x4/5x5 with the lower-right corner cut out ). However I can't figure out where to start with programmatically cutting images ( which will be loaded from own gallery in sdcard or database from app ) in the puzzle pieces.
  I've been looking over the internet and nothing really helped me.</p>
  
  <p>What is the best way to cut up this image and store it in a new database (and still will be able to slide them)? Just a push in the right direction would be appreciated.</p>
