PURPOSE: To provide a beautiful plotting result by making a crack generated at the connecting part of a curved line and a straight line or the curved line and another curved one min., regardless of line width, without remarkably increasing arithmetic processing quantity. CONSTITUTION: When the curved line is approximated to the minute length of straight line to execute plotting through the use of a prescribed output method, the curved line 700 to be plotted is divided into prescribed plural number of minute straight lines and a position of each of the segments to be plotted including the minute straight lines (701-703) relative to the whole curved line is detected so that the minute straight lines 701 to 703 with length decided by a length control means is plotted in accordance with the segment position to be plotted. The position of respective end parts of the minute straight lines 701-703 are decided by adjusting the central angle of the segment with respect to the center of the curved line in accordance with the segment position. |
