title: Issue with Imagick and also with phmagick: Postscript delegate failed / No such file or directory
body: <p>I'm using imagick 3.0.1 and also phmagick (http://www.francodacosta.com/phMagick/download). No matter what, both are giving me the same kind of error when I try to convert a PDF to JPEG.</p>
  
  <p>For example:
  <strong>Postscript delegate failed `/tmp/magick-bfxIrUJ5': No such file or directory @ error/pdf.c/ReadPDFImage/669</strong></p>
  
  <p>I'm using Ghostcript-9.05 (running on /usr/local/bin/gs).
  Also ImageMagick-6.7.6-8 (running on /usr/local/bin/convert).</p>
  
  <p>I already checked folder's permission (755). ImageMagick works wonderful from Terminal.</p>
  
  <p>For example, my PHP using Imagick:</p>
  
  <pre><code>//use imagick
  $im = new imagick( '/pdf/553571072.pdf' );
  
  // convert to jpg
  $im-&gt;setImageColorspace(255);
  $im-&gt;setCompression(Imagick::COMPRESSION_JPEG);
  $im-&gt;setImageFormat('jpeg');
  
  //write image on server
  $im-&gt;writeImage('/jpg/553571072.jpg');
  </code></pre>
  
  <p>By the way Imagick it's showing up in my phpinfo(). I'm working on linux/apache/amd64.</p>
  
  <p>Any advice will be highly appreciated!</p>
