title: How to combine imshow() and moveWindow() in openCV with python?
body: <p>I'm updating the cv2.imshow() command in a endless Loop and I want to manipulate the window position because the window is always on the top of my display and a small part is invisable. </p>
  
  <p>The cv2.moveWindow() command is a nice solution for my task but is there an other way to set the window position only once and not to repeat the command in every Iteration?</p>
  
  <p>I want to update the window every 500 ms. Is there a better way to display the image-stream with fixed window position?</p>
  
  <pre><code>while true:
     (...)
     img = cv2.imread('test.jpg', cv2.IMREAD_COLOR)
     cv2.imshow('image',img)  
     cv2.moveWindow('image',200,200)
     (...)
  </code></pre>
