  • Method and computer program product for reducing colormap flashing
    Patent number: 7009621
    Abstract: A method and computer program product for reducing colormap flashing on a display system where the display system has a single hardware colormap. The method includes the steps of intercepting a request from an application program for an allocation of a private colormap, and transparently simulating the allocation of the private colormap using the default colormap. In this manner, colormap flashing is reduced as the default colormap is used to satisfy private colormap requests.
