I posted a SUN raster file color to mono converter named 8to1 in
comp.sources.misc. The shar file includes two independent files.
8to1.c --
This program converts a 8-bit depth sun raster file (both color,
i.e. rgb are different, and grey, i.e. rgb are the same, and both
standard format and byte-encoded format) to a 1-bit depth mono sun
raster file. If your color image has no colormap, this program would
provide a default grey scale color map. It implements several halftone
algorithms from Digital Halftones by Dot Diffusion in acm Transactions
on Graphics, such as error diffusion, ordered dither and dot diffusion
with and without edge enhancement.
scload.c --
a screenload type of program, but more entertaining, and actually
better than screenload. The only restriction is that the default
frame better is /dev/fb. It's written by Raymond Kreisel, the author
of touchup.
So welcome to use the program, i would like to hear from you whether you
think it's useful or not. Enjoy!
