HRESULT FlipRotateSource(IWICBitmapSource *pBitmapSource, WICBitmapTransformOptions options, IWICBitmapFlipRotator **ppFlipRotator)
{
    HRESULT hr = E_INVALIDARG;

    if (pBitmapSource)

            hr = pFactory->CreateBitmapFlipRotator(&pFlipRotator);
        }

        if (SUCCEEDED(hr))
        {
            hr = pFlipRotator->Initialize(pBitmapSource, options);
        }

        if (SUCCEEDED(hr))
        {
            *ppFlipRotator = pFlipRotator;
        }

        if (pFlipRotator)
        {
