title: Void to Boolean Processing
body: <p>I'm trying to check if the .save method is execute but I'm getting "Cannot convert from void to boolean" error. How could I check it? Also the <code>img.save()</code> doesn't work in a web applet, any clue why it doesn't work?</p>
  
  <pre><code>PImage img  = get (180, 0, 620, 400);
  
  if( img.save("img/111,jpg") )
  {
  fill(0, 255, 0);
  }
  else
  {
   fill(255, 0, 0);
  }
  </code></pre>
