ImageMagick errors and fixes

The failures people actually hit, and the fix that actually works — including the two independent causes behind almost every PDF problem.

Every error on this page has a dedicated fix

These are the eleven ImageMagick failures people actually hit, in rough order of how often they come up. Each links to a page with the cause, the fix, and — where it matters — a note on when you should not apply the fix.

Two of these cause most PDF problems

If a PDF conversion fails, it is almost always one of two things, and they are independent — you can hit both in sequence. Either policy.xml is blocking the PDF coder, or Ghostscript is not installed. Neither is a problem with your command.
