Detailed Description

Simple implementation of the PGM image format.

This struct holds a bare-bones image loaded from a PGM or PPM file. Once loaded and pre-processed, each pixel in this struct will contain how far from the edge of the logo each pixel is, using the manhattan distance (|dx| + |dy|).

pixels in char * pixel can be addressed using (y * width) + height.
