PHP Uncaught exception 'ImagickException' with message 'FailedToExecuteCommand'

Question

I've installed the ImageMagick PHP extension on a MAC via pecl. it's showing up under phpinfo(), and lists PDF as a supported format.

I'm trying to read in a PDF and convert it to an image. However the constructor throws an exception when the source is a PDF. Image files work successfully.

$im = new imagick('TestDoc.pdf[0]'); // Throws Exception when PDF specified.
//$im = new imagick('TestImage.png'); // Succeeds.
$im->setImageFormat('jpg');
header('Content-Type: image/jpeg');
echo $im;

The tmp file mentioned in the output is created, but is 0 bytes. If I execute the full 'gs' command in the message (using actual files) on the command line, it works successfully.

ImageMagick and GhostScript were installed with brew.

In PHP, system('echo $PATH'); gives /usr/bin:/bin:/usr/sbin:/sbin 'gs' is in /usr/bin/

Does anyone have a suggestion. A web search for the exception message turns up nothing specific.

Many thanks Gary.

Never used imageMagick myself but the documents says it needs GhostScript to read the PDF documents

PDF support :   Requires Ghostscript to read. 

EDIT: Have you checked that GhostScript is working?
