旋转从前置摄像头捕获的图像-Windows Phone 8

Question

I do basic Windows Phone application. I need capture photos by front facing camera. Preview is OK, but captured phoho is rotated(90°).

CS:

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
    {
        if (PhotoCamera.IsCameraTypeSupported(CameraType.FrontFacing) == true)
        {            
            cam = new PhotoCamera(CameraType.FrontFacing);
            cam.CaptureImageAvailable += new EventHandler<Microsoft.Devices.ContentReadyEventArgs>(cam_CaptureImageAvailable);
            viewfinderBrush.SetSource(cam);               
        }
        else
        {
            txtMessage.Text = "No front camera";
        }
    }

XAML:

<Canvas x:Name="viewfinderCanvas" Height="640" Width="480" Tap="viewfinder_Tapped" Margin="0,138,0,46" Grid.RowSpan="2">
        <Canvas.Background>
            <VideoBrush x:Name="viewfinderBrush">
                <VideoBrush.RelativeTransform>
                    <CompositeTransform
                        x:Name="viewfinderTransform"
                        CenterX="0.5"
                        CenterY="0.5"
                        Rotation="-90"/>
                </VideoBrush.RelativeTransform>
            </VideoBrush>
        </Canvas.Background>
    </Canvas>

Sorry for my English...

Try Removing the SupportedOrientations and Orientation from the page and check. then changing the rotation to 90
