ABSTRACT:
An electronic image processing system includes a controller for receiving character font data from a main memory and for converting it to image data utilizable by a raster output device capable of formatting the image data in a plurality of scan lines onto an imaging medium. The controller includes an input memory coupled to the main memory for receiving character font data therefrom, a data pattern memory for providing a predetermined pattern of data in response to a predetermined address signal, and a plurality of band buffer memories each capable of storing image data representing a predetermined number of scan lines constituting an image band, each band buffer memory having enable input lines and associated data input lines. The input memory is addressed to access character font data therefrom, such accessed character font data being then applied to respective enable input lines of a selected one of the band buffer memories. The predetermined address signal is applied to the data pattern memory in order to access the predetermined pattern of data and apply same to respective data input lines of the selected band buffer memory. Additionally, the selected band buffer memory is addressed to load into an addressed memory location the predetermined pattern of data only with respect to those data lines whose associated enable input lines are enabled by the character font data.
