Abstract
A real time graphic processor is disclosed which processes graphic cell specifications on a scan line-by-line basis to generate pixel data. The pixel data from each cell specification is assembled to form a completed scan line of pixel data which is used to modulate a printing element, such as a laser diode. The invented graphic processor contains a special purpose cell specification processor which, in addition to generating the pixel data, modifies the cell specification by substituting new horizontal location and cell height indicator values. The modified graphic cell specification is then recirculated to the cell specification processor memory for processing the next scan line.
