Abstract: A method is presented which eliminates the extra steps by an application to call a graphics function. The method eliminates the intercepting layer or program between the application and the graphic functions. The method may call hardware and software graphics functions directly and thus requires fewer processing steps and thereby reduces the amount of work the host computer must perform. The method and apparatus enables copy image data into a computer screen window faster than a comparable image display system that intercepts every call that an application makes to a graphics function.The method and apparatus enables an application program to directly control the location of image data in memory. The present invention enables movement of image data within memory or out of memory to make room for higher priority images. These features enable an application program to move image data between memories for different displays so that an image can move between screens.
