title: Adding scale of image zoom displayed
body: <p>I want to add x,y-scale of an image in a wpf application. Something like:</p>
  
  <p><img src="https://i.stack.imgur.com/bDgjl.png" alt="Image in WPF applciation."></p>
  
  <p>This screen shot is from MATLAB. My pan and zoom in WPF is working fine. The numbers shown here are number of rows(columns). When I zoom or pan, the display content (rows/columns visible) will change too, so the scale should change accordingly. </p>
  
  <p>I am looking for hints/tips because currently I am not sure where to start. I Googled but could not find something useful. (commercially available solutions are also fine)</p>
