PROBLEM TO BE SOLVED: To provide the shading drawing method which draws a shade part fast irrelevantly to the number of colors. SOLUTION: This method performs shading drawing for image data on a specific shape, can specify an arbitrary color in an image area to be drawn, and paints It out with straight lines which never overlap with one another. In concrete, the shading drawing is carried out through a 1st process step which sets a start and an end point for straight-line drawing in the image area to be drawn and draws a straight line specified in an arbitrary color between the start and end points, a 2nd process step which sets the end point of the straight line drawn in the last process step as a new start point, sets another point difference from the start point in the image area to be drawn as a new end point, and draws a straight line specified in an arbitrary color between those start and end points, and a 3rd process step which paints out the inside of the image area to be processed by repeating the 2nd process step as many times as specified. |
