BOOL DrvStartBanding(
| IN SURFOBJ *pso, | |
| IN POINTL *pptl | |
| ); |
DrvStartBanding prepares the driver for banding and returns the origin of the first band.
Parameters
pso
Points to a SURFOBJ structure that describes the banding surface.
pptl
Pointer to the origin of the first band.
Return Value
DrvStartBanding returns TRUE if it succeeds; otherwise, it returns FALSE.
Comments
To actually realize the band contents rendered to the surface identified by pso, DrvNextBand must be called.
The supplied surface must previously have been marked as a banding surface in EngMarkBandingSurface. The size of the band is determined by device and/or driver limitations, and is known only to the driver.
