Saves a texture to a file.
HRESULT D3DXSaveTextureToFile( LPCTSTR pDestFile, D3DXIMAGE_FILEFORMAT DestFormat, LPDIRECT3DBASETEXTURE9 pSrcTexture, CONST PALETTEENTRY * pSrcPalette );
If the function succeeds, the return value is D3D_OK. If the function fails, the return value can be the following: D3DERR_INVALIDCALL
The compiler setting also determines the function version. If Unicode is defined, the function call resolves to D3DXSaveTextureToFileW. Otherwise, the function call resolves to D3DXSaveTextureToFileA because ANSI strings are being used.
This function handles conversion to and from compressed texture formats.
If the volume is nondynamic (because of a usage parameter set to 0 at the creation) and located in video memory (the memory pool set to D3DPOOL_DEFAULT), D3DXSaveTextureToFile will fail because D3DX cannot lock nondynamic volumes located in video memory.
