Have recently upgrade to imagemagick 7.0.8-14 and have lost the ability to convert a pptx file to a jpg(or any other file format). Was working version before upgrade. The below is the out put from running the convert cmd. Happens on all pptx that have been run against it.

imagemagick version: 7.0.8-14 ghostscript version: 9.07 centos 7

$ convert test.pptx[0] -thumbnail 650x650 -gravity center -extent 1500x1000 s1.jpg

  • Not sure this is the issue, but see https://stackoverflow.com/questions/52861946/imagemagick-not-authorized-to-convert-pdf-to-an-image/52863413#52863413. Ghostscript 9.07 is rather old. You might upgrade. I believe the current version is at least 9.25 – fmw42 Dec 05 '18 at 05:22
  • I'd need to see the PDF file to comment, but that message sequence says 'something is wrong with your PDF file'. While normally I would agree with the comment from fmw42, currently upgrading Ghostscript to the most recent version will not help. You could try version 9.24, that might work for you. – KenS Dec 05 '18 at 19:03
  • I agree with KenS. Some newer versions of Ghostscript have had problems. But 9.23 was a good one for me. – fmw42 Dec 09 '18 at 19:35
  • Perhaps your destination folder is not writable by imagemagick. Seem to have the same error, but need to do further investigation at a later point. – pbaldauf Jan 24 '19 at 14:50

could you share your current version of Ghostscript by running the below command?

rpm -qa ghostscript

In case the version is anything above and including 9.07-31.el7_6.1, could you try to downgrade to 9.07-31 and report if it is fixing your problem? To downgrade to that version, run the below command:

yum downgrade ghostscript-9.07-31.el7

If this was fixing your problem, I would be more than happy if you could share the pptx file with me (if possible).

For more info, see:

https://bugzilla.redhat.com/show_bug.cgi?id=1657694

This problem should be fixed now with a release of ghostscript-9.07-31.el7_6.6.

Kind regards, -Martin
