title: Moving Image in ScrollViewer (UWP)
body: <p>I've got a <code>Image</code> in <code>Scrollviewer</code>...</p>
  
  <pre><code>&lt;ScrollViewer x:Name="Scrollster" ZoomMode="Enabled" MinZoomFactor="1" MaxZoomFactor="4"
            HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" ManipulationMode="All"&gt;
      &lt;Image x:Name="Img" Source="{x:Bind ImgSource}" Stretch="UniformToFill" PointerPressed="Img_PointerPressed"/&gt;
  &lt;/ScrollViewer&gt;
  </code></pre>
  
  <p>I want to move Image when I drag image with Mouse Pointer!</p>
  
  <p>I tried: </p>
  
  <pre><code>private void Img_PointerPressed(object sender,PointerRoutedEventArgs e)
  {
    var p = e.Pointer;
  }
  </code></pre>
  
  <p>but I can't get pointer position to change scrollviewer postion. </p>
  
  <p>What's wrong with my code? Am I doing it right?</p>
