PURPOSE:To compose drawing line data in the form of run-length data as they are without restoring the run-length data. CONSTITUTION:Unit run data used basically to find unit run data after next composition are read, one by one, out of upper and lower drawing line data according to a current position painter indicating the end point of a run after composition, and then stored as working data. According to the transparency of the two working data, the working data to be utilized preferentially is determined (T12) and the color code of the preferential working data is employed as the unit run data after the composition (T13 and T15). Further, the run length of the unit run data after the composition is calculated according to which preferential working data is determined (T17 and T18). |
