System and method for automatic resolution reduction.

摘要

A resource oriented host computer-printer system is disclosed in which the host computer and printer share information and data processing duties. A system and method for analyzing the execution times for draw primitives allows the host computer to determine whether the printer will be able to render draw primitives in real-time. A resource assembler calculates the cost of executing each draw primitive within a band to determine if the printer can render the draw primitive in real-time. If the band is too complex for the printer to render in real-time, the printer may pre-render the band or the host computer will render the band and transmit the bit-map of that band to the printer. The host computer makes a series of decisions as to the best form for transferring data from the host computer to the printer. If the printer cannot store the bit-map data file, the bit-map data file is compressed. If the printer cannot store the compressed bit-map data file, the host computer will reduce resolution in two stages, if necessary, until the printer can store the reduced resolution bit-map data file. The second stage of resolution reduction is guaranteed to fit within the printer. The host computer displays a message advising the user that the resolution has been reduced.
