tiny, stupid bitmap image format
PBJ is a really tiny, stupid image format for (monochrome) bitmaps. It's comparable to the PBM file format but it's even more trivial. The format goes like this:
It's not a very space-efficient format, but that's why God invented GZIP. If you pass this library a file ending in ".pbj.gz" or ".pbjz", it will decompress it for you.
"PBJ" stands for "Peanut Butter and Jelly." The "J" also stands for "Jay" which is itself a diminuitive for "Jason."
