ABSTRACT:
A method for generating an image having anti-aliasing effect for display on a display system is described. An outline of the image is first generated. The outline includes a plurality of outline points defining a plurality of horizontal and vertical edges of the outline. The outline is then grid-fitted onto a target grid with each of the outline points located at the center of one of a plurality of grid boxes of the target grid such that each of the horizontal and vertical edges of the outline extends through some of the grid boxes of the target grid. The anti-aliasing effect is provided to the grid-fitted outline by determining gray scale of each grid box of the target grid through which one of the horizontal and vertical edges extends. The image has a sharp display image on the display system while having minimized aliasing. An apparatus is also described for generating an image having anti-aliasing effect for display on a computer controlled display system.
