D3DXCreateTextureFromFileInMemory function

Creates a texture from a file in memory.

Syntax

C++


HRESULT D3DXCreateTextureFromFileInMemory(
  _In_  LPDIRECT3DDEVICE9  pDevice,
  _In_  LPCVOID            pSrcData,
  _In_  UINT               SrcDataSize,
  _Out_ LPDIRECT3DTEXTURE9 *ppTexture
);

Parameters

pDevice [in]

Type: LPDIRECT3DDEVICE9

Pointer to an IDirect3DDevice9 interface representing the device to be associated with the texture.

pSrcData [in]

Type: LPCVOID

Pointer to the file in memory from which to create the texture.

SrcDataSize [in]

Type: UINT

Size in bytes of the file in memory.

ppTexture [out]

Type: LPDIRECT3DTEXTURE9*

Address of a pointer to an IDirect3DTexture9 interface representing the created texture object.

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: D3DERR_NOTAVAILABLE, D3DERR_OUTOFVIDEOMEMORY, D3DERR_INVALIDCALL, D3DXERR_INVALIDDATA, E_OUTOFMEMORY.

Remarks

The function is equivalent to D3DXCreateTextureFromFileInMemoryEx(pDevice, pSrcData, SrcDataSize, D3DX_DEFAULT, D3DX_DEFAULT, D3DX_DEFAULT, 0, D3DFMT_UNKNOWN, D3DPOOL_MANAGED, D3DX_DEFAULT, D3DX_DEFAULT, 0, NULL, NULL, ppTexture).

This function supports the following file formats: .bmp, .dds, .dib, .hdr, .jpg, .pfm, .png, .ppm, and .tga. See D3DXIMAGE_FILEFORMAT.

Note that a resource created with this function when called from a IDirect3DDevice9 object will be placed in the memory class denoted by D3DPOOL_MANAGED. When this method is called from a IDirect3DDevice9Ex object the resource will be placed in the memory class denoted by D3DPOOL_DEFAULT.

Filtering is automatically applied to a texture created using this method. The filtering is equivalent to D3DX_FILTER_TRIANGLE | D3DX_FILTER_DITHER in D3DX_FILTER.
