  • Publication number: 20050110799
    Abstract: A method of processing video data includes directing the video data set toward a display device. The display device has horizontal resolution h1 and vertical resolution v1. The video data has horizontal resolution h2 and vertical resolution v2. The video data includes a plurality of scan lines. At least one scan line has at least one line span representing the projection onto that scan line of a graphics vector rendered in the video data. The graphics vector has a slope and the line span has a color and a width. The method includes, for a resultant video data set having a horizontal resolution less than h2, determining a color of an edge resultant pixel in a resultant scan line using, at least in part, the slope of the graphics vector at an edge sub-pixel.
