Ο προβολέας ψηφιακών βιβλίων

Το calibre συμπεριλαμβάνει ένα ενσωματωμένο προβολέα ψηφιακών βιβλίων που μπορεί να δείξει όλες τις κύριες μορφές ψηφιακών βιβλίων. Ο προβολέας ψηφιακών βιβλίων είναι εξόχως προσαρμόσιμος και διαθέτει πολλά προχωρημένα χαρακτηριστικά.

Εκκίνηση του προβολέα ψηφιακών βιβλίων

You can view any of the books in your calibre library by selecting the book and pressing the View button. This will open up the book in the E-book viewer. You can also launch the E-book viewer by itself from the Start menu in Windows. On macOS, you can pin it to the dock and launch it from there. On Linux you can use its launcher in the desktop menus or run the command ebook-viewer.

Highlighting text

When you select text in the viewer, a little popup bar appears next to the selection. You can click the highlight button in that bar to create a highlight. You can add notes and change the color of the highlight. On a touch screen, long tap a word to select it and show the popup bar. Once in highlight mode you can tap the Adjust selection button to change what text is selected, using touch screen friendly selection handles. Drag the handles to the top or bottom margins to scroll while selecting.

You can use the Highlights button in the viewer controls to show a separate panel with a list of all highlights in the book, sorted by chapter.

You can browse all highlights in your entire calibre library by right clicking the View button and choosing Browse annotations.

Finally, if you use the calibre Content server’s in browser viewer, you can have the viewer sync its annotations with the browser viewer by going to Preferences → Miscellaneous in the viewer preferences and entering the username of the Content server viewer to sync with. Use the special value * to sync with anonymous users.

Εξατομίκευση των ρυθμίσεων όψης και αίσθησης για καλύτερη ανάγνωση

You can change font sizes on the fly by using Font size in the viewer controls or Ctrl++ or Ctrl+- or holding the Ctrl key and using the mouse wheel.

Colors can be changed in the Colors section of the viewer preferences.

You can display custom headers and footers such as time left to read, current chapter title, book position, etc. via the Headers and footers section of the viewer preferences.

More advanced customization can be achieved by the Styles settings. Here you can specify a background image to display under the text and also a stylesheet you can set that will be applied to every book. Using it you can do things like change paragraph styles, text justification, etc. For examples of custom stylesheets used by calibre’s users, see the forums.
