Hvad er Okular?

Okular er en universel dokumentfremviser udviklet af KDE. Okular virker på flere platforme, herunder Linux, Windows, Mac OS X, *BSD mm.

Du kan følge udviklingen på projektets hjemmeside.

Baggrund

Udviklingen af Okular begyndte som en del af Google's Summer of Code-program. Projektbeskrivelsen findes i KDE Developer's Corner.

Okular kombinerer KPDF's fremragende funktionalitet med evnen til at fremvise mange forskellige slags dokumenter som PDF, Postscript, DjVu, CHM og andre.

Siden om Dokumentformater beskriver hvilke formater, der kan fremvises og hvilke funktioner, der understøttes i hvert af dem.

Annotering i Okular, som kan gemmes i PDF-filen

Ud over at understøtte mange formater tilbyder Okular funktioner som tekstudvalg, annotering, udtrækning af filer, som er indlejret i et dokument og meget mere. Der er en samling skærmbillerder af Okular i arbejde her.

Du kan kontakte udviklerne og andre brugere på IRC kanalen irc.freenode.org, #okular.

If you are interested in contributing to Okular, please contact the team. Programmers and non-coders are welcome all the same.

Mobile Version

Okular has a mobile version since version 0.16 release in February 2013 ^[1]. The first version was based on the active framework. The mobile viewer was then ported to Kirigami in 2016 by Marco Martin^[2] and finally to Kirigami2 in 2017^[3].

The mobile version doesn't support all features from the desktop version, but provide better touch support and a mobile interface.

You can test the mobile version in your PC by entering

okularkirigami

in your terminal. A nightly android version is also available at the KDE binary factory.

Tips og tricks

Forhåndsvisning af dokumenter / annoteringer

Double-clicking on either one of the Review tools (F6) allows you to make multiple annotations without having to reactivate the tool after the first time.

Hvordan du gemmer dine annoteringer i PDF-filen

Som udgangspunkt gemmer Okular annoteringer i den enkelte brugers lokale mappe. Fra KDE 4.9 kan man vælge at gemme dem direkte i PDF-filen ved at vælge Fil -> Gem som..., sådan at de kan vises i andre PDF-fremvisere. Bemærk, at denne funktion kræver Poppler 0.20 eller nyere for almindelige PDF-dokumenter. Hvis det PDF-dokument du annoterer er krypteret, så kræves Popplaer 0.22 eller nyere.

DRM

By default, Okular follows the PDF specification and don't allow copying text from DRM protected files. However, there is an option in the settings to disable DRM limitations in Settings -> General -> Program Features -> Obey DRM limitations

There was a small controversy in the Debian bug tracker a long time ago, about the default choice to Obey DRM limitations^[4]^[5]. The choice was then explained by an Okular/KPdf developer^[6].

PDF Signature and certificate

Okular can verify if a PDF certificate is valid. But you can not yet create a new signature. See the release note for more information.
