ABSTRACT:
A visual display system and method for use in converting calligraphic symbology information into raster scanned symbology. The system simultaneously generates and displays calligraphic and raster matrix imagery utilizing the same set of software instructions. The imagery is displayed upon a single, hybrid calligraphic/raster matrix display or separate raster matrix and calligraphic displays. A programmable calligraphic symbology generator utilizes digital stroking techniques that successively generates addressing for a matrix arrayed memory and determines the attributes of both the raster matrix generated and calligraphic generated symbology. The information is stored in a single or a plurality of matrix arrayed memories according to desired symbol attributes and system performance.
