ABSTRACT:
A method and apparatus for allocating memory usage in a visual output device having a render engine, a display list memory for storing display list objects and a compressed band buffer memory for storing compressed bitmap data rendered by the render engine. The method includes storing display list objects in the display list memory and detecting that the display list memory is full. Upon detecting the display list memory is full and determining that the compressed band buffer memory is not full, display list data is transferred from display list memory to the compressed band buffer memory, thereby freeing space in the display list memory space for more display list objects.
