Abstract
A method and apparatus for combining multiple image data files of differing sizes, resolutions, and formats in real time into a single data stream for conversion into halftone pixel data for printing by either single or multiple beam recording devices. The data of varying formats is received via a host interface which couples the data to a standard VME bus. The internal CPU reformats the data and stores it on disk memory. The data is routed by the CPU to one of a plurality of scan-line video processors which converts the data into halftone pixel data. The halftone data is routed to a single or multiple beam recording device for printing. A special low resolution image is prepared by the CPU for preview at a video work station.
