This method is an extension to its counterpart, the GPE::BltPrepare method. With the addition of DDGPEStandard
Header, your driver has the flexibility to choose different accelerated blit routines based on information that cannot be specified by GPEBltParms, such as DDGPEPixelFormat, which you can pass in using one of the reserved DWORDs in DDGPEStandard
Header.
Syntax
virtual void BltPrepare(
DDGPEBltParms* pddgpeBltParms
);
Parameters
- pddgpeBltParms
Pointer to a DDGPEBltParms structure.
Return Value
The return value is S_OK, if the function is successful. Otherwise, an error code is returned.
Remarks
The default implementation of this function calls GPE::BltPrepare and ignores the DDGPEStandard
Header passed in.
Requirements
| Header | ddgpe.h |
| Library | Ddgpe.lib |
| Windows Embedded CE | Windows Embedded CE 6.0 and later |
