title: Getting metadata of an APNG image
body: <p>I am trying to get the metadata of an apng image at the moment. I have
  been able to get different frames from one apng file flawlessly and i am using PNGJ (a really great Standalone Java library for reading and writing PNG images), but I
  am not able to get the different info that is stored against every
  apng frame like delay of every frame.</p>
  
  <p>I am at the moment just able to get the simple png image info that is stored in the header part by using </p>
  
  <pre><code>PngReader pngr = FileHelper.createPngReader(File);
  pngr.imgInfo;
  </code></pre>
  
  <p>But I don't know how to have the information stored against the fcTL chunk. How can I do that?</p>
