okular-backend-mupdf's Issues

Can't build on an up-to-date Arch system

It seems no longer working since the name of Okular changed for nearly half a year. Could you fix it as possible?

Crash on most pdfs

I am self compiling this on Debian 12 KDE-wayland. However it segfaults when opening most pdfs, only few can be viewed without issue.

@gustawho hope you can see this, since you maintain the latest fork.

The back trace is

Application: Okular (okular), signal: Segmentation fault

Different zoom level compared to poppler backend

Hi, I tested this through Arch AUR package, and I found mupdf rendering is smaller than poppler rendering on the same zoom level. Following is a screenshot showing a comparison.

Left-Up is poppler 100%, Right-Up is mupdf 100%.
Left-Down is poppler 400%, Right-Down is mupdf 400%.

The whole screen resolution is 2560x1080, the pdf is generated using Adobe InDesign CS 3.0.1

Please update mupdf library. compile failed in recent mupdf on fedora 23(x86-64)

Navigation using Table of Contents not working

Jumping to a section by clicking on an entry in the Contents pane of Okular does not work when using the mupdf backend. This happens with both, version 14.12.3 of Okular (using the Arch Linux package), and the latest git checkout of okular.

This happens consistently with all documents I tried. All of them work fine using the Poppler backend. There is no output on the terminal indicating any error. Here's an example document where this happens: http://schoepe.org/~daniel/example.pdf

Printing support.

Hello when using mudpf-backend I'm unable to print the option is greyed. It would be great to implement it.
