okular line weight

Hi.

I was about to replace 30 instances of Windows 10 installs with some linux distro instead of buying new W11 compatible computers.

But I hit a major snag.

We have to be able use thin lines on pdf viewer so workers can accurately read technical drawings.

I could not find any linux native pdf reader where you can choose line weights.

( “CTRL + 5” in adobe or foxit readers)

Is there any way to add this feature in ocular in a reasonably short time or should I just waste bunch of company money and create lots of e-waste by buying new computers?

hi, welcome.

i have noticed this too and it seems there is widespread disagreement over how to handle line weights in PDF viewers.

some want to render as accurately as possible but this often results in lines that are not visible which make the viewer seem broken.

others (like okular) try to render all the lines to ensure the document is readable.

there is a backend setting for enhancing line weight which you should check to ensure it is set to “no”, but it seems to be redundant to the already preferred mode of render (to show all the lines).

did find this entry in ~/.config/okularpartrc

BWContrast=5

not sure what it does.
