ID3DXPRTBuffer::ExtractTexture method
Extracts coefficient data from a color channel of the buffer for a specified range of coefficients, and adds the data to an IDirect3DTexture9 object.
Syntax
HRESULT ExtractTexture(
[in] UINT Channel,
[in] UINT StartCoefficient,
[in] UINT NumCoefficients,
[in] LPDIRECT3DTEXTURE9 pTexture
);
Parameters
-
Channel [in]
-
Type: UINT
Buffer color channel from which to extract texture data.
-
StartCoefficient [in]
-
Type: UINT
Starting value of the buffer coefficient from which to extract texture data.
-
NumCoefficients [in]
-
Type: UINT
Number of scalars, beginning at StartCoefficient, from which to extract texture data.
-
pTexture [in]
-
Type: LPDIRECT3DTEXTURE9
Pointer to a IDirect3DTexture9 texture object that will store coefficients.
Return value
Type: HRESULT
If the method succeeds, the return value is S_OK. If the method fails, the return value can be one of the following: D3DERR_INVALIDCALL, E_OUTOFMEMORY.
