D3DXCreateVolumeTextureFromFile Function

Creates a volume texture from a file.

Syntax

HRESULT D3DXCreateVolumeTextureFromFile(      

    LPDIRECT3DDEVICE9 pDevice,
    LPCTSTR pSrcFile,
    LPDIRECT3DVOLUMETEXTURE9 ppVolumeTexture
);

Parameters

pDevice
[in] Pointer to an IDirect3DDevice9 interface, representing the device to be associated with the volume texture.
pSrcFile
[in] Pointer to a string that specifies the filename. If the compiler settings require Unicode, the data type LPCTSTR resolves to LPCWSTR. Otherwise, the string data type resolves to LPCSTR. See Remarks.
ppVolumeTexture
[out] Address of a pointer to an IDirect3DVolumeTexture9 interface, representing the created texture object.

Return Value

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_NOTAVAILABLE This device does not support the queried technique.
D3DERR_OUTOFVIDEOMEMORY Microsoft?Direct3D?does not have enough display memory to perform the operation.
D3DERR_INVALIDCALL The method call is invalid. For example, a method's parameter may have an invalid value.
D3DXERR_INVALIDDATA The data is invalid.
E_OUTOFMEMORY Direct3D could not allocate sufficient memory to complete the call.

Remarks

The compiler setting also determines the function version. If Unicode is defined, the function call resolves to D3DXCreateVolumeTextureFromFileW. Otherwise, the function call resolves to D3DXCreateVolumeTextureFromFileA because ANSI strings are being used.
This function supports the following file formats: .bmp, .dds, .dib, .jpg, .png, and .tga.
Mipmapped textures automatically have each level filled with the loaded texture.
When loading images into mipmapped textures, some devices are unable to go to a 1x1 image and this function will fail. If this happens, then the images need to be loaded manually.
Note that a resource created with this function will be placed in the memory class denoted by D3DPOOL_MANAGED.
