title: How can I use the latest version of Imagemagick on Heroku?
body: <p>Heroku Cedar-14 stack currently runs a version of ImageMagick (6.7.7-10) that is nearly a year old:</p>
  
  <pre><code>Running `identify -version` attached to terminal... up, run.8227
  Version: ImageMagick 6.7.7-10 2014-03-06 Q16 http://www.imagemagick.org
  Copyright: Copyright (C) 1999-2012 ImageMagick Studio LLC
  Features: OpenMP
  </code></pre>
  
  <p>I want to use the <code>-canny</code> option that performs edge detection in an image, but this was only introduced in a later version of ImageMagick.</p>
  
  <p>The only available buildpack for ImageMagick on Heroku does not work on the Cedar-14 stack:
  <a href="https://github.com/mcollina/heroku-buildpack-imagemagick">https://github.com/mcollina/heroku-buildpack-imagemagick</a></p>
  
  <p>Is there a way I can use ImageMagick v6.8.9-0 or later on Heroku?</p>
  
  <p>Thanks in advance!</p>
