Imagemagick error when trying to load file

I am trying to create a jpg preview of a pdf file as outlined in this question: How do I convert a PDF document to a preview image in PHP?

The relevant code to do so is:

$im = new imagick('file.pdf[0]');
$im->setImageFormat('jpg');
header('Content-Type: image/jpeg');
echo $im;

I am running this on my localhost on a pdf file but get the error:

Fatal error: Uncaught exception 'ImagickException' with message 'Imagick::__construct(): HTTP request failed! HTTP/1.0 400 Bad Request '

The error is being triggered here:

$im = new imagick(build_url('uploads/files/'.$file_data['file_name'].'[0]'));

This is the same as the first line in the example code above, and I am providing the full url path to the pdf file, when I echo that it provides the correct path 

http://oursite.localhost:8888/uploads/files/file_name.pdf[0]

Does anyone know what is causing this error? Thank you!

ImageMagick is quite bad as HTTP client. Pull down your image first, then feed it into ImageMagick as blob

Use following:

 $image = file_get_contents(build_url('uploads/files/'.$file_data['file_name'].'[0]'));
 if ($image !== false)
   {
     $im = new imagick();
     $im->readImageBlob($image);
   }
 else
   {
     echo "Uh-oh... Cannot load image from URL!";
   }
