ABSTRACT:
Antialiasing method and apparatus for video applications. A method for antialiasing a video graphic. A determination is first made as to the relative position of a desired pixel being within the polygon and proximate to the edge of the polygon. Once the relative position is known, then a determination is made as to whether it meets a first predetermined condition or a second predetermined condition. If the relative position meets the first condition, then the color of at least an adjacent pixel is blended with the color of the desired pixel in a predetermined proportion. If the relative position meets the second predetermined condition, then the color of at least an adjacent pixel is blended with the color of the desired pixel in a predetermined proportion.
