title: How to get the GIF image size dimensions from byte array in AS3?
body: <p>How to do I get the GIF image dimensions from a raw byte array?</p>
  
  <p>Here is the <a href="https://stackoverflow.com/questions/41304761/is-there-a-simple-method-to-match-an-array-of-bytes-in-an-byte-array">related</a> question. I'm trying to find if there is a string of bytes that contain the width and height. </p>
  
  <p>I found <a href="https://en.wikipedia.org/wiki/GIF" rel="nofollow noreferrer">this</a> page on the GIF format but I'm not sure how to decipher it. It looks like position 6 and position 8 contain the width and height?</p>
