PURPOSE:To execute a high-speed and correct painting out processing by executing an inverse processing as to specific one among picture elements contained in the outline of a closed area in parallel to one coordinates axis in a coordinates system to express the closed area from a prescribed outline point and, simultaneously, executing a scanning. CONSTITUTION:The top of a head is used as a start point, and the top next to it is used as an end point. A straight line to connect the start point and end point is prepared, and the picture element of one point is prepared from the side of the start point. From the obtained one point up to an Xmax, a straight line parallel to an X axis is drawn in an inverse mode. The Xmax expresses a maximum coordinates value among all tops of graphic data. When a plotting action up to the end point is completed, the end point of the present is changed to the start point, and the top next to it further is made into the end point. When the final top is made into the start point, the top of the head is made into the end point, and all actions are completed. |
