ABSTRACT:
An improved graphics processing system and method are described for magnifying visual output information for printing, display, or other output. A graphics engine transforms display information so as to magnify one or more components or areas of an output image for display via output hardware such as a screen or printer. Magnification parameters are supplied to the graphics engine by one or more magnification applications. In an embodiment of the invention, the graphics engine performs compositing of magnified and unmagnified content for display. In an alternative embodiment, the graphics engine outputs corresponding scaled image material to the appropriate magnification application for rendering. In a further embodiment, the graphics engine may operate in both modes. The magnified output according to various embodiments of the invention enhances the accessibility of the computer system for visually handicapped or impaired users by providing high quality magnification and increased system and application stability.
