  • Method for managing non-rectangular windows in a raster display
    Patent number: 6097388
    Abstract: A method is provided for managing windows in a raster display. The method includes generating a first display map defining sequential picture element runs, each run having a common set of windows containing the picture elements of the run. The windows are arranged in a stacking order and include a topmost window which is drawn in the raster display, the other windows being covered by the topmost window. A window operation occurs when a window is added, deleted or moved, and when the window stacking order is changed. In response to a window operation, there is generating a second display map defining sequential picture element runs, each run having a common set of windows containing the picture elements of the run. The windows are arranged in a stacking order and including a topmost window which is drawn in the raster display, the other windows being covered by the topmost window.
