ABSTRACT:
A method, apparatus and computer program product are provided for implementing enlarged virtual screen using dynamic zone compression of screen content in a graphical user interface of a computer. A maximum uncompressed view window size is determined. An uncompressed area from a virtual screen is transferred to an actual screen buffer. For each zone within a compression area, a compression ratio is identified, a zone bitmap is copied and reduced according to the identified compression ratio; and the reduced zone bitmap is transferred to the actual screen buffer. The uncompressed area optionally is centered on a focus window that can change to a new window at any time, or can remain in a fixed area of the screen. Resizing the focus window optionally is restricted to the maximum uncompressed view window size. Hint text within the compression area optionally is displayed uncompressed.
