Abstract
Disclosed is a method of modifying a graphics command. The method receives a graphics command comprising a drawing operation and a pattern (ROP3) of the region and obtains spatial frequencies of the pattern. The method determines if the obtained spatial frequencies of the pattern in the graphics command define a transparency attribute of the region to be rendered and replaces at least the pattern in the graphics command with a transparency coefficient based on the obtained spatial frequencies.
