ABSTRACT:
Raster operations (ROPs) are executed using a few core blocks which implement the logical operations (e.g., AND, OR, XOR) forming the basis for the raster operations. In an embodiment, the core blocks are generated only for the basic Boolean operations namely AND, OR and XOR for the corresponding operands (one or two of the source, paint and destination). Each logical operation is performed by using the appropriate core block.
