Method of enabling display transparency for application programs without native transparency support

Abstract
A transparent layer of display data may be provided over the top of another layer of display data on a display so that the user may see both layers clearly and simultaneously. This capability may be provided without employing modifications to the application program generating the data to be displayed transparently. That is, transparency effects may be provided for the display output data of application programs that do not have native transparency support. Embodiments of the present invention provide a generalized interface for accessing transparent display features by an application program. Creating transparent graphics for an application program lacking native transparency support includes selecting a virtual display to receive display data output from the application program, displaying non-transparent display data on a primary display, drawing the display data on the virtual display, and representing the display data from the virtual display transparently on the primary display along with the non-transparent display data.
