title: Saving both Xaml and InkCanvas to image in UWP app
body: <p>I need a way to save both Xaml and <code>InkCanvas</code> to image.</p>
  
  <p>If I try to save a <code>FrameworkElement</code> using <code>RenderTargetBitmap</code> class, then the content of InkCanvas is not saving.</p>
  
  <p>I can use <code>await inkCanvas.InkPresenter.StrokeContainer.SaveAsync(stream);</code> to succeed with saving InkCanvas's content, but the underlying UI will no be saved.</p>
  
  <p>What is the correct way to save the content of my app with some drawings over it (prodided by InkCanvas control)?</p>
