Claims

[Claims for Utility Model Registration] 1. A straight line drawing means for drawing the boundary line of a closed area in a straight line so that the filled part of each line is sandwiched between an even number of border lines, and a straight line drawn by the straight line drawing means. Scan the drawing line by line in turn,
An image processing apparatus comprising: a filling means for filling in pixels from the odd-numbered boundary line that intersects to the next intersecting boundary line in the line scanning. 2. A straight line drawing means for drawing a boundary line of a closed area in a straight line so that the filled part of each line is sandwiched between an even number of border lines, and a straight line drawing made by the straight line drawing means for each line in order. scan,
a filling means for filling in pixels from an odd-numbered boundary line to the next intersecting boundary line in the line scanning; and a filling means for filling in boundary data that is not drawn when drawing a straight line by the straight line drawing means. An image processing apparatus comprising: a drawing addition means for adding a drawing to the drawn drawing.
