Abstract
A plurality of linework data including run length data are combined at a high speed and without reconverting run-length data to pixel image data. During the combining operation based on linework data stored in a linework operation memory 50, subsequent linework data is supplemented from an external storage unit 64 to an input linework memory 48. When one of the plurality of linework data in the linework operation memory is used up, the supplement of linework data is transferred from the input linework memory to the linework operation memory, both of which are random access memories. In the combining process of run-length data, unit-run data are respectively extracted from each linework data according to the value of a current position pointer representing an end point of the run which has already been combined. Combined unit-run data is produced by comparing the working data for the plurality of linework data.
