title: How to extract frames of an animated GIF with PHP
body: <p>I search for a long time how to extract frames from an animated GIF with PHP... unfortunaly I just found how to get their duration...</p>
  
  <p>I really need to extract the GIF frames and their duration to apply some resize, rotate, etc, on each and then to regenerate the GIF with edited frames !</p>
  
  <p>I don't want to use any software, external library (like ImageMagick), just PHP: in fact I need to allow my class <a href="http://phpimageworkshop.com/" rel="noreferrer">http://phpimageworkshop.com/</a> to work with animated GIF.</p>
  
  <p>If you have any idea, I'm listening you ^^ !</p>
