Method and apparatus for increasing pixel interpretations by implementing a transparent overlay without requiring window identifier support

摘要

A method, apparatus, and computer instructions for displaying data. Each entry in a plurality of entries for an overlay window attribute table (WAT) is set with identical information in which a window identifier is unnecessary for accessing the information in the overlay WAT. Information in a color WAT is retrieved using the set of window identifiers in response to receiving a set of window identifiers. The information in the overlay WAT is retrieved without requiring the window identifier. Pixels are displayed on a display screen using the information retrieved from the color WAT and the information retrieved from the overlay WAT.
