D3DDDIARG_CAPTURETOSYSMEM structure (d3dumddi.h)
The D3DDDIARG_CAPTURETOSYSMEM structure describes the parameters of a bit-block transfer (bitblt) from a capture buffer to a video memory surface.
Syntax
typedef struct _D3DDDIARG_CAPTURETOSYSMEM {
[in] HANDLE hSrcResource;
[in] RECT SrcRect;
[in] HANDLE hDstResource;
[in] UINT DstSubResourceIndex;
[in] RECT DstRect;
} D3DDDIARG_CAPTURETOSYSMEM;
Members
[in] hSrcResource
A handle to the source resource.
[in] SrcRect
A RECT structure for the source rectangle.
[in] hDstResource
A handle to the destination resource.
[in] DstSubResourceIndex
The index to the destination surface within the resource.
[in] DstRect
A RECT structure for the destination rectangle.
Remarks
Because the source resource that is specified by the hSrcResource member is a capture buffer, it is guaranteed to be a stand alone resource. Therefore, in a call to CaptureToSysMem, the Microsoft Direct3D runtime is not required to supply an index to a sub source surface within the resource. However, an index to a sub source surface is required when the runtime calls the user-mode display driver's Blt function to perform a more general bitblt.
