The BltPrepare routine is an extension to its counterpart, the GPE BltPreparefunction. With the addition of DDGPEStandardHeader, your driver now has the flexibility to choose different accelerated blt routines based on information that can't be specified by GPEBltParms(ex.DDGPEPixelFormat), which you can pass in using one of reserved DWORDs in DDGPEStandardHeader.

The default implementation of this function is calling GPE BltPrepare, ignoring the DDGPEStandardHeaderpassed in.

virtual void BltPrepare ( DDGPEBltParms *


A pointer to a DDGPEBltParmsstructure.

Return Values

The return value is S_OK if the function is successful. Otherwise an error code is returned.
