body: <p>how to merge Image and videoBrush in one image in windows phone 7?</p>
  
  <p>For example there is the code:</p>
  
  <pre><code>&lt;Canvas x:Name="viewfinderCanvas" Width="640" Height="480" 
                     HorizontalAlignment="Left" &gt;
              &lt;Canvas.Background&gt;
                  &lt;VideoBrush x:Name="viewfinderBrush" /&gt;
              &lt;/Canvas.Background&gt;
              &lt;Image source="myImage.png"/&gt;
          &lt;/Canvas&gt;
  </code></pre>
  
  <p>If for example I add a picture in the <code>Image</code> - Logo with transparent background, and I want to when you click the "Make a photo" logo remained on the photo.</p>
  
  <p>Image from the camera to take with the help of:</p>
  
  <pre><code>PhotoCamera cam = new Microsoft.Devices.PhotoCamera(CameraType.Primary);
  </code></pre>
  
  <p>How to make it so that when you save a photo on it was applied to a picture of the Image (my logo)?</p>
