A method of determining pixel parameters, wherein the pixel parameters were clamped to a valid range. The method includes a step of accessing a geometric primitive comprising a plurality of vertices wherein each vertex has associated therewith a plurality of parameters including a pair of texture coordinates. During rasterization of said geometric primitive performed in a rasterization module of graphics pipeline, a respective pair of texture coordinates for each pixel of said geometric primitive are computed using interpolation. Each computed texture coordinate includes an integer portion and a fractional portion. Only the fractional portions of said texture coordinates are propagated to a downstream data fetch module of said graphics pipeline.
