D3DXFillTexture function
Uses a user-provided function to fill each texel of each mip level of a given texture.
Syntax
HRESULT D3DXFillTexture(
_Out_ LPDIRECT3DTEXTURE9 pTexture,
_In_ LPD3DXFILL2D pFunction,
_In_ LPVOID pData
);
Parameters
-
pTexture [out]
-
Type: LPDIRECT3DTEXTURE9
Pointer to an IDirect3DTexture9 interface, representing the filled texture.
-
pFunction [in]
-
Type: LPD3DXFILL2D
Pointer to a user-provided evaluator function, which will be used to compute the value of each texel. The function follows the prototype of LPD3DXFILL2D.
-
pData [in]
-
Type: LPVOID
Pointer to an arbitrary block of user-defined data. This pointer will be passed to the function provided in pFunction.
Return value
Type: HRESULT
If the function succeeds, the return value is D3D_OK. If the function fails, the return value can be one of the following values: D3DERR_INVALIDCALL.
Remarks
Here is an example that creates a function called ColorFill, which relies on D3DXFillTexture.
// Define a function that matches the prototype of LPD3DXFILL3D
VOID WINAPI ColorFill (D3DXVECTOR4* pOut, const D3DXVECTOR2* pTexCoord,
const D3DXVECTOR2* pTexelSize, LPVOID pData)
{
*pOut = D3DXVECTOR4(pTexCoord->x, pTexCoord->y, 0.0f, 0.0f);
}
// Fill the texture using D3DXFillTexture
if (FAILED (hr = D3DXFillTexture (m_pTexture, ColorFill, NULL)))
{
return hr;
}
