STROKE-TO-RASTER DISPLAY CONVERSION

摘要

A digital address filter is provided which converts straight-line and arc analog stroke data into digitized images which comply with Bresenham raster display criteria and can be displayed on a raster scanned monitor or LCD. Data collected over a preselected (M pixel x M pixel) spatial window are repetitively matched against a set of pixel template patterns premitted by the Bresenham criteria. After each full-frame iteration, the display pixel(s) corresponding to the best-fit templates are lighted.
