PROBLEM TO BE SOLVED: To shorten a plotting processing time by reducing a command size in filling or clipping a plurality of continuous rectangular regions. SOLUTION: When data for a point changed toward a plus in a Y-axial direction is defined to be a reference point lastPos as a variable showing a present position, if data set on a variable Pos1 showing the next point is changed in the positive direction of the X-axis (a rate of change = nowW) and in addition data set on a variable Pos2 showing the following next point is changed in the positive direction of the Y-axis (a rate of change = nowH), the data set on the Pos1, Pos2 are registered, and when the output resolution size of the nowW or nowH is 1 or less, coordinate point data for the Pos1 is thinned out. Thus, the command size is reduced and this issue is achieved. |
