Well, this time, it's an example of the Floyd-Steinberg error diffusion
algorithm. I'm trying to convert 8-bit pseudo-color images into dithered
black and white images, suitable for output on a laser printer. Any
references/pointers are greatly appreciated.

P.S. I've already got a copy of "Digital Halftoning" by Robert Ulichney,
but since I have no experience with Fourier Transforms, I'm not having
much luck in extracting enough information to generate a subroutine that
works.
