A method is provided for processing multiple types of pixel component
representations. The method first includes identifying a plurality of
texels in a texture pattern grid that correspond to a pixel. Thereafter,
information components of the pixel, i.e. R, G, B, and .alpha. are
multiplied if the information components of the pixel are in a
postmultiplied representation. Further, a colorkeyed replacement operation
is carried out if the information components of the pixel are in a
colorkeyed representation and at least one of the texels substantially
matches a colorkey. Next, a position is interpolated on the texture
pattern grid between the texels that corresponds to the pixel. Finally,
the information components of the pixel are filtered.
