How to fix “error exists on this page” PDF error

[brianwebb01]

Hey Guys,

I'm getting this error when trying to open my Prawn generated PDF in
Acrobat: An error exists on this page. Acrobat may not display the
page correctly. Please contact the person who created the PDF document
to correct the problem.

My PDF does use a background image on every page, has lots of pages
(usually 75+), and has lots of transparent images, but nothing that
should be causing an error. Additionally Mac's Preview shows no
issues, and if you press "OK" on the Acrobat error, everything is
fine.

I ran the Preflight tool in Acrobat Professional to check for PDF
syntax errors and found no errors but some warnings "Unbalanced q and
Q operators".

Any ideas on how I can get the error to go away?

What version of Prawn are you using? We refactored the graphics state
stack recently and that fixed a bunch of these kinds of issues. We're
soon going to cut a proper 0.11 release that includes these fixes --
it's only because we haven't had a full stable release in quite a
while.

That could well be doing it.

You're not using master yet, are you? Master should be fixed thanks to
Jonathan Greenberg.

We're aiming to cut a gem this week.

Cheers,

We're releasing a new gem soon, or else you can give master a try to
take advantage of the changes Jonathan contributed.

If your cutting the gem this week I'll just wait and see if that fixes
it, then report back.
