D3DXCreateVolumeTextureFromResourceEx function
Creates a volume texture from a resource specified by a string. This is a more advanced function than D3DXCreateVolumeTextureFromResource.
Syntax
HRESULT D3DXCreateVolumeTextureFromResourceEx(
_In_ LPDIRECT3DDEVICE9 pDevice,
_In_ HMODULE hSrcModule,
_In_ LPCTSTR pSrcResource,
_In_ UINT Width,
_In_ UINT Height,
_In_ UINT Depth,
_In_ UINT MipLevels,
_In_ DWORD Usage,
_In_ D3DFORMAT Format,
_In_ D3DPOOL Pool,
_In_ DWORD Filter,
_In_ DWORD MipFilter,
_In_ D3DCOLOR ColorKey,
_Inout_ D3DXIMAGE_INFO *pSrcInfo,
_Out_ PALETTEENTRY *pPalette,
_Out_ LPDIRECT3DVOLUMETEXTURE9 *ppVolumeTexture
);
Parameters
-
pDevice [in]
-
Type: LPDIRECT3DDEVICE9
Pointer to an IDirect3DDevice9 interface, representing the device to be associated with the texture.
-
hSrcModule [in]
-
Type: HMODULE
Handle to the module where the resource is located, or NULL for module associated with the image the operating system used to create the current process.
-
pSrcResource [in]
-
Type: LPCTSTR
Pointer to a string that specifies the resource name. If the compiler settings require Unicode, the data type LPCTSTR resolves to LPCWSTR. Otherwise, the string data type resolves to LPCSTR. See Remarks.
-
Width [in]
-
Type: UINT
Width in pixels. If this value is zero or D3DX_DEFAULT, the dimensions are taken from the file. The maximum dimension that a driver supports (for width, height, and depth) can be found in MaxVolumeExtent in D3DCAPS9.
-
Height [in]
-
Type: UINT
Height, in pixels. If this value is zero or D3DX_DEFAULT, the dimensions are taken from the file. The maximum dimension that a driver supports (for width, height, and depth) can be found in MaxVolumeExtent in D3DCAPS9.
-
Depth [in]
-
Type: UINT
Depth, in pixels. If this value is zero or D3DX_DEFAULT, the dimensions are taken from the file. The maximum dimension that a driver supports (for width, height, and depth) can be found in MaxVolumeExtent in D3DCAPS9.
-
MipLevels [in]
-
Type: UINT
Number of mip levels requested. If this value is zero or D3DX_DEFAULT, a complete mipmap chain is created.
-
Usage [in]
-
Type: DWORD
0, D3DUSAGE_RENDERTARGET, or D3DUSAGE_DYNAMIC. Setting this flag to D3DUSAGE_RENDERTARGET indicates that the surface is to be used as a render target. The resource can then be passed to the pNewRenderTarget parameter of the SetRenderTarget method. If either D3DUSAGE_RENDERTARGET or D3DUSAGE_DYNAMIC is specified, Pool must be set to D3DPOOL_DEFAULT, and the application should check that the device supports this operation by calling CheckDeviceFormat. D3DUSAGE_DYNAMIC indicates that the surface should be handled dynamically. For more information about using dynamic textures, see Using Dynamic Textures.
-
Format [in]
-
Type: D3DFORMAT
Member of the D3DFORMAT enumerated type, describing the requested pixel format for the texture. The returned texture might have a different format from that specified by Format. Applications should check the format of the returned texture. If D3DFMT_UNKNOWN, the format is taken from the file. If D3DFMT_FROM_FILE, the format is taken exactly as it is in the file, and the call will fail if this violates device capabilities.
-
Pool [in]
-
Type: D3DPOOL
Member of the D3DPOOL enumerated type, describing the memory class into which the texture should be placed.
-
Filter [in]
-
Type: DWORD
A combination of one or more D3DX_FILTER controlling how the image is filtered. Specifying D3DX_DEFAULT for this parameter is the equivalent of specifying D3DX_FILTER_TRIANGLE | D3DX_FILTER_DITHER.
-
MipFilter [in]
-
Type: DWORD
A combination of one or more D3DX_FILTER controlling how the image is filtered. Specifying D3DX_DEFAULT for this parameter is the equivalent of specifying D3DX_FILTER_BOX.
-
ColorKey [in]
-
Type: D3DCOLOR
D3DCOLOR value to replace with transparent black, or 0 to disable the colorkey. This is always a 32-bit ARGB color, independent of the source image format. Alpha is significant and should usually be set to FF for opaque color keys. Thus, for opaque black, the value would be equal to 0xFF000000.
-
pSrcInfo [in, out]
-
Type: D3DXIMAGE_INFO*
Pointer to a D3DXIMAGE_INFO structure to be filled in with a description of the data in the source image file, or NULL.
-
pPalette [out]
-
Type: PALETTEENTRY*
Pointer to a PALETTEENTRY structure, representing a 256-color palette to fill in, or NULL.
-
ppVolumeTexture [out]
-
Type: LPDIRECT3DVOLUMETEXTURE9*
Address of a pointer to an IDirect3DVolumeTexture9 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 compiler setting also determines the function version. If Unicode is defined, the function call resolves to D3DXCreateVolumeTextureFromResourceExW. Otherwise, the function call resolves to D3DXCreateVolumeTextureFromResourceExA because ANSI strings are being used.
The resource being loaded must be an application-defined resource (RT_RCDATA).
This function supports the following file formats: .bmp, .dds, .dib, .hdr, .jpg, .pfm, .png, .ppm, and .tga. See D3DXIMAGE_FILEFORMAT.
