摘要： 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.

摘要： 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. If the graphics system does not provide texture elements having the specified resolution, the texture elements which are provided by the graphics system and have a relevant resolution are selected, and those of the footprint are reduced such that the number of texture elements touched by the footprint having a reduced size is essentially equal to or smaller than the specified number.
