title: How to draw transparent background image with Camlimages and Graphics
body: <p>Yesterday I included all the modules of Camlimages Package into my project, I successfully draw images in my graphical window, but the png images (with transparent background) are not drawn with transparent background.</p>
  
  <p>I will show you the image I have, and the result on the graphical window as well as the code.  </p>
  
  <pre><code>  let img = Png.load "./images/3mushrooms.png" [] in
    Graphic_image.draw_image img 0 0
  </code></pre>
