  • Method for determining weighting factors for the color calculation of a color value of texels for a footprint
    Patent number: 7924289
    Abstract: In a method for determining weighting factors for the color calculation of a color value of texels for a footprint covering a plurality of texels in a texel grid, in a graphic system, form information of the footprint is determined at first. Afterwards, the edges of the footprint are determined and the edges determined in this way are approximated by a staircase function. The texels of the texel grid contacted by the staircase function are determined and a weighting factor is determined for each texel containing a portion of the staircase function, depending on the subarea of the respective texel covered by the footprint.

  • Method of analyzing and modifying a footprint
    Patent number: 7221372
    Abstract: In a method of analyzing and modifying a footprint depending on a specified number of texture elements touched by the footprint, in a graphics system providing the texture elements having a resolution, a dimension or a shape of the footprint is initially determined. On the basis of the specified number of texture elements and on the basis of the determined dimension or shape, the resolution of the texture elements associated with the footprint is specified. Then it is determined whether the graphics system provides texture elements having the specified resolution. If the graphics system provides texture elements having the specified resolution, the footprint is preserved.
