D3DXCreateCubeTextureFromFileInMemory function

Creates a cube texture from a file in memory.

Syntax


HRESULT D3DXCreateCubeTextureFromFileInMemory(
  _In_  LPDIRECT3DDEVICE9      pDevice,
  _In_  LPCVOID                pSrcData,
  _In_  UINT                   SrcDataSize,
  _Out_ LPDIRECT3DCUBETEXTURE9 *ppCubeTexture
);

Parameters

pDevice [in]

Type: LPDIRECT3DDEVICE9

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

pSrcData [in]

Type: LPCVOID

Pointer to the file in memory from which to create the cubemap. See Remarks.

SrcDataSize [in]

Type: UINT

Size of the file in memory, in bytes.

ppCubeTexture [out]

Type: LPDIRECT3DCUBETEXTURE9*

Address of a pointer to an IDirect3DCubeTexture9 interface, representing the created cube 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_INVALIDCALL, D3DERR_NOTAVAILABLE, D3DERR_OUTOFVIDEOMEMORY, D3DXERR_INVALIDDATA, E_OUTOFMEMORY.

Remarks

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

The function is equivalent to D3DXCreateCubeTextureFromFileInMemoryEx(pDevice, pSrcData, SrcDataSize, D3DX_DEFAULT, D3DX_DEFAULT, 0, D3DFMT_UNKNOWN, D3DPOOL_MANAGED, D3DX_DEFAULT, D3DX_DEFAULT, 0, NULL, NULL, ppCubeTexture).

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.

This method is designed to be used for loading image files stored as RT_RCDATA, which is an application-defined resource (raw data). Otherwise this method will fail.

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.

D3DXCreateCubeTextureFromFileInMemory uses the DirectDraw surface (DDS) file format. The DirectX Texture Editor (Dxtex.exe) enables you to generate a cube map from other file formats and save it in the DDS file format. You can get Dxtex.exe and learn about it from the DirectX SDK.
