  2. Using Imagemagick (Ghostscript) on cflinuxfs3

This seems to indicate that ImageMagick will search in multiple locations.


When I run that on cflinuxfs3, I get..

  Searching for configure file: "/usr/share/ImageMagick-6.7.7/magic.xml"
  Searching for configure file: "/usr/lib/x86_64-linux-gnu/ImageMagick-6.7.7/config/magic.xml"
  Searching for configure file: "/etc/ImageMagick/magic.xml"
  Searching for configure file: "/usr/share/doc/ImageMagick-6.7.7/magic.xml"
  Searching for configure file: "/home/vcap/.magick/magic.xml"

I would try putting your policy file into `/home/vcap/.magick/`. That's the only path that will be writable to the vcap user.

Hi

I'm using the nodejs-buildpack together with the cflinuxfs3 stack. I would like to convert PDF documents to JPEG images.
In order to do this I'm using Imagemagick together with Ghostscript.

cflinuxfs3 uses the following Ubuntu package: 6.9.7.4+dfsg-16ubuntu6.4
Unfortunately there's a security issue with Ghostscript in this version. Because of that the Ghostscript handled types are disabled in policy.xml.
See https://launchpad.net/ubuntu/+source/imagemagick/8:6.9.7.4+dfsg-16ubuntu6.4

I'd like to override the policy.xml (/etc/ImageMagick-6/policy.xml). 
But I would need root permissions for that, which I don't have.

Unfortunately my CF provider couldn't help me with that problem.
Does anyone here know a workaround for this?

Thanks in advance
Markus
