PURPOSE:To produce an excellent void leading line having the uniform width of an outline and also to freely change the shape of a triangular part and the angle of an oblique line. CONSTITUTION:This processor is provided with a contour point generating part 5 which calculates a double bag-shaped contour coordinate string to produce a void leading line based on the coordinate values of the start, middle and end points stored in a start/middle/end point storing part 2, a contour point storing part 3 which stores the contour coordinate string calculated by the part 5, and a polygon area-filling part 6 which reads the contour coordinate string stored in the part 3 and connects between the contour points by a straight line to develop two bag-shaped leading line outline images in an image storing part 4, thereafter detects two picture elements of value '1' while scanning the raster in the main scanning direction in order to fill an area with the picture elements defined as 1 and then draws a white-on-black leading line by filling the areas of two bag-shaped leading line outline images. |
