title: Java Image Processing using PGM files and Multi-Dimensional arrays
body: <p>I'm in a intro CS class. We've been given a project where we've been supplied a basic file, and a few .PGM files of our school's mascot and things like that. Basically we're told that we need to use the framework they've written, and flip, rotate etc.. this file. </p>
  
  <p>How do you flip or rotate clockwise a PGM file? I'm totally lost as what to do. </p>
