Can you guys please move the mupdf discussion elsewhere? While it is certainly
interesting, it is only tangentially related to this bug.

So I installed the dependencies and tried to build okular-mupdf-backend (from
git master), but it fails with some "Variable not declared in this scope"
error. Also there have been no commits to the repository

I guess you are referring to
https://invent.kde.org/sandsmark/okular-mupdf-backend ? The thing is, there are
multiple unofficial Okular MuPDF generators around...
Moreover, why is this not officially part of

--- Comment #22 from David Hurka ---
No, the muPDF backend is not part of Okular, it is an independent project. Just
search for it in the internet for okular-backend-mupdf or okular-mupdf-backend.

Is this at all still current? I checked out okular from

The Ubuntu Focal mupdf package currently fails to open the file

Be careful - there are considerable differences between these libraries. I
don't really know about pdf.js and PDFium, but pikepdf is quite

I've searched a bit in the code, and at least the rendering proportions issue
is Okular's fault I think:

Pdfinfo from poppler-utils does not show regular units like centimetres or
inches, but it keeps the PDF points. Pdfinfo is a low-level tool that does not
perform unit conversion on its own. However, it does not

Sorry. I just thought you'd be the maintainer of Okular, and wondered why you
are not in the CC list, but apparently this has its reason. Sorry, really.

Do *not* add me to bugs.
I don't understand what makes you think that is normal behaviour, but it's not,
you're only making me ignore you.
