okular VS pdfarranger

Okular

Here is the .git repo: https://invent.kde.org/graphics/okular/

Some more information which might be useful, the library im talking about, is actually a part of the "okular" document viewer (https://github.com/KDE/okular). I want to use its core in my application. (https://github.com/Librum-Reader/Librum/tree/dev/develop)

What I am now thinking about, is to use calibre (https://github.com/KDE/okular). My thought was to try and extract the core of the application (which does all of parsing and creates a QPixmap from it), adapt it to fit my application and use this.

Hey, does anyone know, if the Okular (https://github.com/KDE/okular) core code would run on mobile as well? (ios, android) I m not talking about the gui, just the parsing.

It looks like the scope is pretty limited, so maybe not too much of a concern. Thank you for making us aware it uses JavaScript though, that does bother me since I personally think JavaScript and all traces of it should be banned from planet Earth in entirety and perpetuity. Personally, I keep my PDF viewer in KDE set to evince.

On Linux I like to use:

https://github.com/pdfarranger/pdfarranger and https://gitlab.com/scarpetta/pdfmixtool for such tasks.

Für PDFs verwende ich pdfarranger.

I see some questions in the comments about document splitting and if you are using PDF for the export in scanning, this adds an extra step but may be valuable in the long run. For Linux users at least, there is "pdfarranger" which most distros have. You can install that, load the PDF and re-arrange pages, remove pages, etc.

PDFArranger

So, I guess, pdfarranger might be faster than PDFSam. https://github.com/pdfarranger/pdfarranger

I like PDF Arranger for converting JPEGs to PDFs (open source on Windows) https://github.com/pdfarranger/pdfarranger.

I have always only been using PDF Arranger for manipulating PDF files (merging different files, arranging, adding, deleting pages) and I'm wondering if there really is no KDE equivalent for that application.
