ABSTRACT:
A method and apparatus for allocating memory space in main memory of an associated processor for a plurality of windows. The depth in each window is independent of other windows on the display and can be changed dynamically. An application program is not required to know the frame buffer depth in advance. When a window is created, a default depth (e.g., two bits per pixel) is defined for the window. When a program writes to the window, drawing commands are interpreted and the appropriate depth is provided.
