DDGPE::BltPrepare

  • Article

The BltPrepare routine is an extension to its counterpart, the GPE::BltPrepare method. With the addition of DDGPEStandardHeader, your driver now has the flexibility to choose different accelerated blit routines based on information that cannot be specified by GPEBltParms, such as DDGPEPixelFormatwhich you can pass in using one of the reserved DWORDs in DDGPEStandardHeader.

virtual void BltPrepare(
  DDGPEBltParms* pddgpeBltParms
);

Parameters

  • pddgpeBltParms
    A pointer to a DDGPEBltParms structure.

Return Values

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

Remarks

The default implementation of this function is calling GPE::BltPrepare, ignoring the DDGPEStandardHeader passed in.

Requirements

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
Header: Ddgpe.h.
Link Library: Ddgpe.lib.
