ImageMagick not authorized to convert PDF to an image

Question

I have a program, in which I need to convert a PDF to an image using Image Magick. I do that using the subprocess package:

        cmd = \'magic         


        

Answer 1

I am using Dockerfile to update an image, and suddenly I got the policy.xml file in my way. although the version of Ubuntu (xenial) was the same and ImageMagick as well.

I ended up removing the single line causing my problem.

RUN sed -i 's/^.*policy.*coder.*none.*PDF.*//' /etc/ImageMagick-6/policy.xml

hope this helps someone
