<p>A method and system to scale a graphics image from one graphics display resolution to a different graphics display resolution without the need for creating an entire new set of graphics commands. The present invention allows the non-integer scaling of a graphics image and creates an array of virtual pixels that control intensity of the actual pixels within the graphics memory and keep track of the source of intensity contribution for each actual pixel if scaled graphics images overlap an actual pixel. If one of the multiple sources of intensity for a given actual pixel is subsequently erased, the contribution information allows the actual pixel to be erased in a manner that accounts for the direction of the contribution as well as the actual intensity contribution. <IMAGE></p> |
