The following table shows the Display driver methods with a description of the purpose of each.

Programming element	Description
GPE::AllocSurface	This method executes when the driver must allocate storage for surface pixels.
GPE::BltComplete	This method executes to complete a blit sequence initiated by GPE::BltPrepare. GPE calls this method.
GPE::BltPrepare	This method identifies the appropriate functions needed to perform individual blits.
GPE::GetModeInfo	This method populates a GPEMode structure with data for the requested mode.
GPE::Line	This method executes before and after a sequence of line segments, which are drawn as a path.
GPE::MovePointer	This method executes from applications either to move the hot spot of the cursor to a specific screen location or to hide the cursor.
GPE::NumModes	This method returns the number of display modes supported by a driver. A simple implementation returns 1.
GPE::SetMode	This method executes to enable the device driver based on the Graphics Primitive Engine (GPE) and to request a specific mode for the display.
GPE::SetPointerShape	This method sets the shape of the pointer, the hot spot of the pointer, and the colors to use for the cursor if the cursor is multicolored.
GPESurf::GPESurf	This method creates a system-memory surface and allocates storage.
GPESurf::Init	This method initializes a newly created GPESurf object.
