title: Which Format of Images are supported by OpenCV
body: <p>For a project of mine a require an image(logo of some company) to be overlaid on the main screen and I want only the Logo to be visible not the borders or the extra regions of the image, I even tried overlaying the .png image but then also the borders are visible in black color along with the logo.</p>
  
  <p>Can anyone let me know which format of the image shall I use So that only the logo of my image gets displayed not the extra part which lies in the rectangular part of the image. </p>
  
  <p>If u need more clarification... Please let me know</p>
  
  <p>Thanks :)</p>
