Mam bardzo glupie pytanie.

Jak w #lInux.ie wydrukowac plik tekstowy? O_o 🤣
Ani #Nanonote, ani #Ghostwriter, ani #Kate, #KWrite nie maja opcji wydruku. O_o Dopiero #Okular, czyli tak naprawde multi-przegladarka plikow na cos takiego pozwala.
What the actual f...? 🤣

Argh, filling in a #PDF form with #Evince. I accidentally tick a radio button that I shouldn't have ticked. I now cannot untick it. #Okular seems to have the same problem.

(The form has clearly been authored wrong, since it has 2 separate radio button groups where there should be one, leading to the possibility of having 2 buttons ticked at the same time, but really, I don't want to have to re-fill in the entire form just because nothing will let me undo the selection!)

@wlaatje Okular, universele documentviewer (ipv Adobe, gebruik het vooral voor pdf maar ook ePub, Markdown). Is van KDE en is multiplatform, dus zowel op Linux, MacOS als Windows. https://okular.kde.org/nl/ #okular

I just accidentally discovered Okular can open epubs. Handy!

#Okular is one of my favorite pieces of software. It does one thing, does it well, and doesn't demand a god damn thing from me. Never once have I asked it to open a PDF and it not just do that (excluding corrupted files, as that's not it's fault). It's one of the few pieces of software I can't think of a complaint about.

I 💕 free software. I especially like #KDE #okteta which I frequently use for viewing PDF files when hacking on Poppler and #okular

¿Soy yo o es que #Okular se durmió en sus laureles desde 3 años atrás?

En 2014, fue una de las principales razones por las que me moví de GNOME a KDE Plasma, no había un software decente para leer/anotar formatos de documento portables, desarrollado en GTK. Xournal++ es excelente (lo sigo usando) pero en casos de uso diferentes.

Hoy, creo que Okular es de lo menos destacable entre los programas de base en #KDE #Plasma

I stumbled upon a 2300-pages-long PDF document that actually is a fantastic benchmark for slow search performance (1.5 to 5 minutes) in most PDF readers (including GNOME Papers, Evince and Okular)… so I fired up #Sysprof through GNOME Builder to measure the slowness, and reported my findings in #Poppler for all of you performance optimization aficionados: https://gitlab.freedesktop.org/poppler/poppler/-/issues/1660

You know what, now that I tried #Okular again, it's actually pretty good. Obviously I have to use it a bit longer to discover all the quirks, but so far it has all the functionality I need and more. It also looks quite nice on its own, even though it looks completely out of place between the other GNOME programs, but I don't really mind that.

#Acrobat #Reader ist gerade gestorben.
Also für mich.

Vor zwei Wochen: Durchsuche #PDF nach Text. Kein Treffer. Gebe die Info weiter.

Heute Rückmeldung: "Kann doch nicht sein...blablabla"

Durchsuche PDF erneut nach Text. Kein Treffer.
Frage aus Laune heraus eingebaute #KI:
"Ja, auf Seite drölfhundert kommt das vor."

Frage KI warum die normale Suche das nicht findet: "Ja...vielleicht kein Text...OCR...vielleicht mal anderes Tool verwenden."

Gesagt getan: #Okular runtergeladen. Datei geöffnet. Nach Text gesucht. Gefunden.

Also echt! Hatte den #AcrobatReader eigentlich als Standard im Portfolio. Aber die Basics sollte man doch beherrschen. Ein Versagen hierbei reißt auch eine KI nicht raus.

Can some kind person help me understand and solve a quirk of Okular (23.08.5) on Plasma (5.27.12, Kubuntu 24.04)?

When I click on a link on a pdf document opened in Okular, it seems that Okular does not simply pass the link to my browser (Firefox), but that it first tries to open the link itself. For instance, clicking on an actually broken link, I get a "Host not found" error in an Okular message, rather than from my browser.

I've checked Okular's settings and backends' settings, but can't find anything about links there. In my file associations, anything related to htm and html extensions has Firefox as default.

So what's going on?

Liebe #Linux -Bubble. Vielleicht hat einer von euch einen Tipp fur mich: Ich möchte auf einem Tablet, das auch Stift-Eingabe unterstützt Pdfs lesen und markieren. Bedienung gerne so wie bei #xournal : Finger -> scrollen, Stift -> markieren. Aber warum taugt xournal nicht?
'klassische' PDF -Reader wie #okular speichern die Markierung als markierten Text ab, xournal nur als zwei Layer eines Bilds. Fur meinen Workflow brauch ich ersteres. Okular passt leider beim Werkzeugwechsel nicht mit Touch.

May I make a suggestion:

#Blender, #Kdenlive, #Shotcut, #LibreOffice, #Okular, #Krita, #GIMP, #Inkscape, and #Scribus need to run joint funding campaigns every year.

I don't use Thunderbird that much (I ❤️KMail), but these small tweaks made it so much better!

Something that #Okular does that I FREAKING LOVE 💌 is having the
`File -> Open Containing Folder`
menu option.

Absolute gold, @tsdgeos and team. I'd **love** that in many others like #Krita, #Gwenview... and thousands of non-KDE apps too!

It is very very useful, even if hidden in a menu. Makes it very easy to find related stuff... or simply just to find wherever you put that in.

Wow that is a hard one to answer as I don't use any #Proprietary tools
Back before I moved to Linux & was still on #Windows7 2019, I went out of my way to not use proprietary tools & only used open source tools & tools ported to #Windows from #Linux.
A cheap answer from me would be: #Okular & #Firefox replaced #Adobe Reader for PDFs
The thing about proprietary #Software is you have to pay for it & I was never into that🏴‍☠️ 🦜️
On #Android I've been replacing proprietary Apps with open source

@os_sci

In my experience Libreoffice Draw breaks a lot of PDFs. It allows editing them tho.

Instead what I use
- #PDFArranger to combine, cut and change order
- #Firefox to add text and images ("signatures")
- #GIMP to really blacken pages (export as JPG and use in PDFArranger)
- #Okular to fill out forms, read and mark

Not great to have so many in parallel but this works.

An all-in-one #AlternativeTo #PDF24 is #StirlingPDF

https://github.com/Stirling-Tools/Stirling-PDF

Looking for a PDF viewer allowing me to specify an arbitrary amount of of rows/columns to view a PDF. #Okular tops out at 8. Weirdly, in the source code¹ a maximum of 10 is set. But even recompiling² with it patched to 20 still only 8 are allowed. So there has to be something going on in the background. 🤷

Any other recommendations? I want to scroll through *many* PDF pages next to each other and also make an overview screenshot (yes pdfnup...)

We getting closer to a #gpg4win 5 release. 😀 Here is a new Beta version:

https://files.gpg4win.org/Beta/gpg4win-5.0.0-beta369/gpg4win-5.0.0-beta369.exe

featuring #kleopatra and #okular updates and comes of course with the fresh #GnuPG version 2.5.12

Still amazed that #Firefox's (#LibreWolf's, in my case) built-in pdf.js does a better job doing basic #PDF annotation and signing than #Okular or #Evince.

HOW?!? XD

Kudos to @adamsdesk / @adamsdesk for cluing me in!

I've installed the old #Oxygen style on #bazzite via rpm-ostree:

rpm-ostree install oxygen-cursor-themes oxygen-sounds plasma-oxygen-qt5 plasma-oxygen-qt6 oxygen-fonts oxygen-icon-theme oxygen-mono-fonts oxygen-sans-fonts plasma-oxygen

It's way better to use then Breeze for #touchscreens - i also use it on #SteamOS on my #SteamDeck

I also switched for #konsole, #okular and #gwenview to #Fedora packages. This works much better for remote volumes than the #flatpak versions:

flatpak remove okular gwenview konsole; rpm-ostree install okular gwenview konsole

Praxistipp: openSUSE 15.6 und Okular Drucken:

In Okular ist aus Sicherheitsgründen der ps-Treiber standardmäßig nicht installiert. Daher bei Druck von sicheren PDFs "okular-spectre" via yast nachinstallieren.

Wichtig für Leute, die keine Bahn-App verwenden wollen:

Bei Ausdrucken mit QR-Code ist im Okular Druckdialog unter pdf-Optionen noch "Rasterung erzwingen" anzuhaken. Dann funktioniert auch das Drucken von pdf wie z.B. Bahnkarten in Okular.

He tenido que instalar #Okular pues #Evince no posibilita elegir el color, transparencia y otros detalles al resaltar. En Gnome se usa para resaltar solo. En Okular tienes muuuchas más opciones. Es típico de KDE.

Debería mirar si existe la posibilidad de añadir la opción de tachar en Evince o sugerirla.
