Abstract

A technique is described for drawing all or part of an arbitrary ellipse onto a raster for devices such as a digital plotter, a raster display, or an all-points-addressable graphics printer. The ellipse may have any ratio of major or minor axis and any orientation relative to the coordinate axis of the graphic space.
