title: OpenCV displaying 2 images adjacently in the same window
body: <p>I am trying to display 2 images horizontally adjacent to each other in the same window using OpenCV.</p>
  
  <p>I have tried using adjustROI function for this.Image 1 has 1088 pixels width and 2208 pixels height while Image 2 has 1280 pixels width and 2208 pixels height.Please suggest what could be wrong in the code below.All I am getting is an image of size Image2 with content from Image2 as well.</p>
  
  <pre><code>Mat img_matches=Mat(2208,2368,imgorig.type());//set size as combination of img1 and img2
  img_matches.adjustROI(0,0,0,-1280); 
  imgorig.copyTo(img_matches);
  img_matches.adjustROI(0,0,1088,1280);
  imgorig2.copyTo(img_matches);
  </code></pre>
