title: Compatible issues with Imagick Transparent?
body: <p>I have my local with version  ImageMagick 6.7.3-10 (PHP 5.2.10) and server side with  ImageMagick 6.5.4-7 (PHP 5.3.9). It happened that server side doesn't generate transparent background but other colours still working. However local are just good with transparent background. Anyway I can solve in order to use transparent background on server side?</p>
  
  <pre><code>$canvas  = new Imagick();
  $canvas-&gt;newImage( $size, $size, new ImagickPixel( 'transparent' ) );
  </code></pre>
