ABSTRACT:
A user invokes an application program and initiates a request to display an image on a display device. In response, a display device driver creates a bitmap in an offscreen video memory of an adapter card. The display device driver then writes data corresponding to the requested image to the bitmap. At an appropriate time, the display device driver copies the bitmap from the offscreen video memory to an onscreen video memory of the adapter card over an adapter bus. The requested image is then displayed on the display device using the bitmap stored in the onscreen video memory.
