title: Image Magick: resize and fill doesn't work
body: <p>this is what I'm doing:</p>
  
  <pre><code>convert input.png -fill white -resize 2480x3508^ out.png
  </code></pre>
  
  <p>and I get:</p>
  
  <pre><code>convert: invalid argument for option `2480x3508^': -resize.
  </code></pre>
  
  <p>Version: ImageMagick 6.2.8 06/11/08 Q16 <a href="http://www.imagemagick.org" rel="nofollow noreferrer">http://www.imagemagick.org</a></p>
  
  <p>The error doesn't present itself if the '^' at the end of the Geometry argument is removed.</p>
