Abstract
Methods and apparatus for facilitating the sharing of graphics rendering operation implementations between different pixel formats. A lookup table is generated that stores the descriptions of the various rendering operation implementations. A plurality of chains of inherited object descriptors allows traversal from specific to more general descriptions of pixel formats and composition operations. Using these chains, the lookup table can be searched for a rendering operation implementation that best matches the specified criteria.
