Qu'est-ce qu'Okular ?

Okular est un visualiseur de documents universel développé par KDE. Okular fonctionne sur plusieurs plates-formes, y compris, mais sans s'y limiter, Linux, Windows, Mac OS X, *BSD, etc.

Vous pouvez suivre le développement sur la page d'accueil du projet.

Contexte

Its development began as part of Google's Summer of Code program. The description of the project can be found at KDE Developer's Corner.

Okular combine les fonctionnalités excellentes de KPDF avec la possibilité de prendre en charge différentes sortes de documents, tels que PDF, Postscript, DjVu, CHM, et d'autres.

La page des formats compatibles contient un tableau décrivant plus en détails les formats pris en charge et les fonctionnalités offertes pour chacun des cas.

Annotations dans Okular sauvegardables dans le fichier PDF

En plus de supporter de nombreux formats, Okular offre des fonctionnalités telles que la sélection de texte, l'annotation, l'extraction de fichiers incorporés dans un document, et bien d'autres surprises. Les captures d'écran d'Okular en action peuvent être vues ici.

Vous pouvez parler aux développeurs et aux autres utilisateurs sur IRC, irc.freenode.org canal #okular.

Si vous êtes intéressé pour contribuer à Okular, veuillez contacter l'équipe. Les programmeurs comme les non-programmeurs sont les bienvenus au même titre.

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.

Trucs et astuces

Révision de documents / Annotations

Double cliquez sur n’importe quel outil de Révision (F6) vous permet de faire de multiples annotations sans avoir à réactiver l’outil à chaque fois.

Comment garder les annotations que vous avez faites dans le fichier PDF :

Par défaut, Okular range les annotations dans le répertoire data local de chaque utilisateur. Depuis KDE 4.9, on peut d'une manière facultative, les sauvegarder directement dans un fichier PDF en choisissant Fichier -> Sauvegarder sous ..., afin qu'elles puissent être lues par d'autres visionneuses de PDF. Notez que cette fonction nécessite Poppler 0.20, ou plus récent, pour les documents PDF usuels. Si le document PDF que vous annotez est crypté, cette fonction nécessite Poppler 0.22 ou plus récent.

DRM

By default, Okular follow 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 release note for more information.
