viewbits

A simple glut example program.

Reads in a file, and interprets the data as pixels.
Usage: viewbits FILE [width] [height]
If the file parameter is ommitted, file data will be read from standard input (unless on windows)
File input is truncated at 5 MB
    
Controls:
R                   Toggle RGB / grayscale
Z                   Zoom in
X                   Zoom out
Up/Down Arrow keys  Scroll display
Scroll wheel        Scroll display

viewbits was built to use freeglut, but will most likely build just as well with regular glut with few modifications
