If a WIC bitmap encoder doesn't support a given pixel format, it
returns the closest supported pixel format.

It can be implemented by renaming D3DXSaveSurfaceToFileW() to
D3DXSaveSurfaceToFileInMemory(), and making it to use IStream which
uses the memory storage. Then, D3DXSaveSurfaceToFileW() will just call
D3DXSaveSurfaceToFileInMemory() and write the returned buffer to a
Do I have to implement D3DXSaveSurfaceToFileInMemory() first?
