[poppler] Printing of certain PDF files does not work with "fit-to-page" because of wrong BoundingBox values in the PostScript

Wed Oct 28 04:22:40 PDT 2015

Reason why I wanted your patch pushed is, because it fixes this fit-to page problem.
I never thought about changing the okular binary and as I mentioned before I am using your patch without problems since you created it.

Now to okular. There is a special section at bugs.kde.org for okular and printing.
https://bugs.kde.org/buglist.cgi?component=printing&product=okular&resolution=---

And there is already one Bug 348172 - Scaling options missing in print dialog
https://bugs.kde.org/show_bug.cgi?id=348172

There are many reports of printing problem caused by the wrong BoundingBoxes
https://bugs.kde.org/show_bug.cgi?id=337578
https://bugs.kde.org/show_bug.cgi?id=348171
https://bugs.kde.org/show_bug.cgi?id=351408

Many user did change to evince to bypass this problem.
All this bugs can be closed when the new patch is accepted.

Nevertheless the fit-to-page should be a setting in the print dialogue.
As Bug 348172 is still unconfirmed I guess there won't be progress soon.

Stefan

The main problem with setting the option fit-to-page in okular unconditionally
is that it's impossible to print true to scale anymore. That renders okular
nearly useless for printing. A quick patch is to open
/usr/lib64/libokularcore.so.6.0.0 with an binary editor e.g. okteta, find the
string fit-to-page and replace the leading 'f' with 0. It's an ugly patch but
after that okular is useable again ;).

Did you report this bug already? I wasn't sure where to report it, because I
think it's a problem of a missing feature in the print-dialog as well. To my
understanding the print-dialog is part of Qt.

Martin Pahl
