Windows Driver Kit DDI reference (ns-d3dhal-_d3dhal_dp2blt)

_D3DHAL_DP2BLT structure

Description

DirectX 9.0 and later versions only.

D3DHAL_DP2BLT is used for two dimensional surface blts when D3dDrawPrimitives2 responds to the D3DDP2OP_BLT command token.

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`

Specifies a flag that indicates the type of filtering that the driver must perform. This member is set to zero to indicate that the driver can use its own filtering technique or is set to one of the following flags.

Flag	Meaning
DP2BLT_LINEAR	Set for linear filtering.
DP2BLT_POINT	Set for point filtering.

Remarks

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.
