PURPOSE: To improve the omission or protrusions projections of pixels, and to provide an image with high quality by adopting an inverting technique of packing inside pixels in a polygon. CONSTITUTION: Each pixel of a non-horizontal edge is inverted, and all the right pixels of each edge pixel are inverted to the edge of a bit map window in the same way. When the non-horizontal edge is successively processed, this procedure is repeated to the last edge, and the procedure is completed then. In this way, all the right pixels of an edge 1 are inverted to sold black, access to an edge 2 is performed, the inverting procedure is suppressed for this edge 2 is horizontal, and access to an edge 3 is performed. Then, all the right pixels of the edge 3 are inverted to black, and turned into to an off state. Thus, this scanning is continued, and as a result, an overall W-shaped polygonal image is packed with on-pixels. |
