Works from command line, not via PHP??

Hi!

This code run from the command line and from within PHP using exec produces quite different output:

/usr/local/ImageMagick-6.3.4/bin/identify -debug All '/Library/WebServer/Documents/play/multipage/input/test.pdf'

From the command line it works and from PHP it does not work. Specifically, from the command line the debug includes:

2007-05-30T17:05:42-04:00 0:01 0.030u 6.3.4 Resource identify[5101]: resource.c/unknown/406/Resource

Oddly, from PHP the debug includes this code in the same place:

Opening module at path "/usr/local/ImageMagick-6.3.4/lib/ImageMagick-6.3.4/modules-Q16/coders/avi.la"

To avoid a huge code dump I've tried to only post relevant code sections. It looks to me like the difference between "PNM" and "AVI" is the greatest difference in the debug code dumps. But, I'm not really sure if that's the issue at all. :/


Output of --version is identical from both methods of calling imagemagick:

Version: ImageMagick 6.3.4 05/05/07 Q16 http://www.imagemagick.org

I'll happily provide additional information. Thanks in advance for your help!

It turns out it was a problem with ghostscript. It didn't know the search path to find the gs executable.

I edited the delegates.xml file to include a full path to gs:

command='"gs"

became:

command='"/sw/bin/gs"

And all is now well with the universe... until the next issue.
