title: OpenCV - How to enable scrolling to windows with images?
body: <p>So currently I open images created with openCV with something like</p>
  
  <pre><code>                cvNamedWindow( "Original Image", CV_WINDOW_AUTOSIZE );
                  cvShowImage( "Original Image", original );
  </code></pre>
  
  <p>but my images are quite large and go off the screen like shown here</p>
  
  <p><img src="https://i.imgur.com/yy5NKKS.jpg" alt="Lena"></p>
  
  <p>I want windows to be resizable or at least the size of the users screen but with scrolling.</p>
  
  <p>How to do such thing? </p>
