PROBLEM TO BE SOLVED: To provide an image processor which can generate double marks in a sharp shape even for a corner part of the outline of an original figure. SOLUTION: The original figure read in by an image scanner 3 is converted into a bit map figure, which is stored in a bit map figure data area of a RAM of an image processor 1. The outline of black dots of this figure is converted by raster scanning into directional vector data, which are expanded in a vector figure data area of the RAM. Then the directional vector which is thus processed is painted to generate a bit map figure, which is expanded in a bit map figure data area of the RAM; and a specific pixel expanding process is performed to expand a vector figure outside the outline of the original figure at equal intervals, thus generating double marks. Consequently, the sharp shape is obtained for the corner part where there is a polygon of the original figure. |
