XGTextureAddressComputer::CopyFromSubresource Method

Copies the 2D or 3D linear input data from the given subresource (mip + slice) of the resource.

Syntax

public:
HRESULT CopyFromSubresource(
         VOID *pLinearData,
         UINT32 Plane,
         UINT32 Subresource,
         const VOID *pTiledResourceBaseAddress,
         UINT32 RowPitchBytes,
         UINT32 SlicePitchBytes
)

Parameters

pLinearData
Type: VOID *

[in, out] The location to copy the data into.

Plane
Type: UINT32

[in] The plane.

Subresource
Type: UINT32

[in] The subresource to copy from.

pTiledResourceBaseAddress
Type: VOID *

[in] The base address of the tiled resource to copy from, as a pointer to VOID. For offline texture preparation, pTiledResourceBaseAddress does not need to be properly aligned.

RowPitchBytes
Type: UINT32

[in] The row pitch, in bytes.

SlicePitchBytes
Type: UINT32

[in] The slice pitch, in bytes.

Return value

Type: HRESULT

S_OK if successful; otherwise, an error message.

Remarks

This method copies the 2D or 3D linear input data from the given subresource (mip + slice) of the resource, using pTiledResourceBaseAddress as the resource’s base address. For offline texture preparation, pTiledResourceBaseAddress does not need to be properly aligned.
