This script produces a ROM image that can be used to turn any parallel ROM into a character generator for 6845-style CRTCs and similar video output systems.

It works by going over one character cell at a time, starting at the top left corner of an image and processing through each row (if there are multiple), turning every pixel with a value of #000 (black) into a 1 (every other value is a 0).

An example font is provided.
