ABSTRACT:
The pattern drawing system consists of a first data processor which develops the outline font data, calculates the coordinates of the points on the profile of a pattern and, according to the calculated profile coordinates, draws the profile of the pattern; and a second data processor which paints the interior of the profile drawn by the first data processor concurrently with the calculation of the profile coordinates by the first data processor. This configuration allows the first data processor to calculate the profile coordinates of a desired pattern while the second data processor is doing the painting. Such parallel operations improve the efficiency of the pattern drawing that uses the outline font data.
