ABSTRACT:
A method and system for generating a set of computer instructions to implement a logical operation to be performed on a plurality of bitmaps. A Boolean equation is specified that has a plurality of terms that use Boolean operations. Subsets of computer instructions are generated that implement each of the Boolean operations of the terms. When executing a routine to display a bitmap (bitBLT routine), a logical operation and a plurality of bitmaps are specified. The routine determines which of the generated subsets of computer instructions are needed to implement the specified logical operation. The determined subsets of computer instructions are then retrieved and combined to form the set of computer instructions that implements a logical operation. The set of computer instructions can then be executed to effect a display of a bitmap with the specified logical operation.
