title: How to get coordinates of click on rawImage in Unity using Hololens?
body: <p>So right now I have a this hierarchy:
  <strong>Cube</strong> → <strong>Canvas</strong> → <strong>RawImage</strong></p>
  
  <p>And I want to get the coordinates of my click on the rawimage, but I dont know where to start right now.</p>
  
  <ol>
  <li>In the HoloToolkit is an GazeManager, where the raycast is performed and there is the property HitPosition. So by using <em>GazeManager.Instance.HitPosition</em> I should get the click position in world. But how do I get from this to the coordinates on the Canvas? </li>
  <li>I can trigger <em>OnInputClicked(InputClickedEventData eventData)</em> if I use <em>IInputClickHandler</em>. But from the eventData I wont get Information about the click.</li>
  <li>I found <a href="https://answers.unity.com/questions/892333/find-xy-cordinates-of-click-on-uiimage-new-gui-sys.html" rel="nofollow noreferrer">this</a> but cant transfer it into my needs. Because his eventData has more options.</li>
  <li>I guess there wont be a difference to get the click from the rawimage, or the canvas or the cube, because they have all the same size.</li>
  </ol>
