The “Postage Stamp Rasteriser”,
a small, highly portable and
Reality Hardened rasteriser which scan converts lines and
filled concave or convex polygons. Polygon scan conversion
contains compensation for almost a dozen problems of
singularities and numerical instabilities which cause
incorrect results in the simple algorithms you find in
textbooks. Optional TIFF output is available to aid in the
inclusion of preview images in DOS and Windows PostScript
files. Written in portable C; public domain.
