D3DHAL_DP2SURFACEBLT structure (d3dhal.h)
DirectX 9.0 and later versions only.
D3DHAL_DP2SURFACEBLT is used for two dimensional system memory to video memory surface blts when D3dDrawPrimitives2 responds to the D3DDP2OP_SURFACEBLT command token.
Syntax
typedef struct _D3DHAL_DP2SURFACEBLT {
DWORD dwSource;
RECTL rSource;
DWORD dwSourceMipLevel;
DWORD dwDest;
RECTL rDest;
DWORD dwDestMipLevel;
DWORD Flags;
} D3DHAL_DP2SURFACEBLT;
Members
dwSource
Specifies the handle to the source surface.
rSource
Specifies a RECTL structure that specifies the upper left and lower right points of a rectangle on the source surface. These points define the area of the source blit data and its position on the source surface.
dwSourceMipLevel
Specifies the sublevel of a MIP-map texture that is the source of the blt.
dwDest
Specifies the handle to the destination surface.
rDest
Specifies a RECTL structure that specifies the upper left and lower right points of a rectangle on the destination surface. These points define the area in which the blit should occur and its position on the destination surface.
dwDestMipLevel
Specifies the sublevel of a MIP-map texture that is the destination for the blt.
Flags
Unused
Remarks
The D3DDP2OP_SURFACEBLT operation code is identical to the D3DDP2OP_BLT operation code except that D3DDP2OP_SURFACEBLT is only used to copy system memory to video memory and is never used for stretch blts or color conversion. Because D3DDP2OP_SURFACEBLT is not used for stretch blts, no flags are currently defined.
The dwSource or dwDest member specifies the kernel handle to the top-level surface and the dwSourceMipLevel or dwDestMiplevel member specifies the sublevel for the MIP-map chain where the blt occurs.
