Abstract
Abstract A graphic symbol generator includes a cathode-ray tube assemblage disposed opposite a photosensitive film. The electron beam of the cathode-ray tube assembly while being driven in a raster scan mode, is intensity modulated in accordance with stored coded combinations of binary signals which represent the graphic symbol. Provisions are made to control the line density or resolution of the scan in two dimensions during the generation of the graphic symbol as an array of parallel line segments.
