PURPOSE:To shorten time for processing by decreasing a rate to double write a dot. CONSTITUTION:A circular filled pattern, of which the inside is painted out by dots, with the width of a thick line as a diameter and a hollow pattern, for which the dots inside the filled pattern are removed, are generated. In the biginning, the filled pattern is plotted with the start point of the thick line as a center (A). Afterwards, the hollow pattern is plotted with respective pattern plotting positions as centers up to the end point of the thick line while calculating the pattern plotting positions (X marks) to be changed just for one dot every time in the extending direction of the thick line [(B), (C) and (D)]. Thus, since dots are plotted excepting for the start point while using the hollow pattern of which the internal dots are removed, the rate to overlap the dots is decreased in comparison with the case of plotting while using only the filled pattern. |
