Two-dimensional graphics program accelerating method in which function or procedure flags are set to indicate whether a particular function or procedure needs to be processed

摘要

Method for accelerating the execution of a 2D graphics program, whereby a flag is set in a function or procedure of a 2D graphics program that indicates whether a subsequent function or procedure is to be processed or not. If flags are set by all functions or procedures whose output and input values represent the interrogation function of the procedures, these functions or procedures do not need to be processed.
