We have a new library of simple image manipulation functions (imglib) that includes this, but at this moment the only routine that dithers to monochrome is embedded in the module that prints images to an Imagen printer. Within the next few days I'll generalize the dithering a bit and will make imglib available by anonymous FTP. That'll also include a few programs using imglib and a collection of 1,130 images. ---------------- Paul Raveling Raveling@isi.edu
