D3DXFillTexture function

Article
03/15/2021

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;
}
