Web/* Riemersma dither * * This program reads in an uncompressed gray-scale image with one byte per * pixel and a size of 256*256 pixels (no image header). It dithers the image * and writes an output image in the same format. * * This program was tested with Borland C++ 3.1 16-bit (DOS), compiled in * large memory model.
