E-raamatute vaatur

calibre sisaldab sisseehitatud e-raamatute vaaturit, mis suudab avada kõiki levinumaid e-raamatute formaate. E-raamatute vaatur on väga kohandatav ja paljude võimalustega.

E-raamatute vaaturi käivitamine

Sa saad lugeda iga raamatut oma calibre kogus, valides raamatu ja vajutades nupule Loe. See avab raamatu E-raamatute vaaturis. Windowsis saad E-raamatute vaaturit omaette avada ka Start menüü kaudu. macOS-is saad selle dokile kinnitada ja selle käivitada sealt. Linuxis saad kasutada selle käivitajat töölaua menüüdes või käitada käsuga 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 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 also Shift+click or right click to extend the selection, particularly useful for multi-page selections.

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.

Read aloud

The viewer can read book text aloud. To use it you can simply click the Read aloud button in the viewer controls to start reading book text aloud. The word being currently read is highlighted. Speech is synthesized from the text using your operating system services for text-to-speech. You can change the voice being used by clicking the gear icon in the bar that is displayed while Read aloud is active.

You can also read aloud highlighted passages by adding the Read aloud button to the selection bar in the viewer preferences under Selection behavior.

Märkus

Support for text-to-speech in browsers is very incomplete and bug-ridden so how well Read aloud will work in the in-browser viewer is dependent on how well the underlying browser supports text-to-speech. In particular, highlighting of current word does not work, and changing speed or voice will cause reading to start again from the beginning.

Märkus

On Linux, Read aloud requires Speech Dispatcher to be installed and working.

Märkus

On Windows, not all installed voices may be visible to the SAPI sub-system that is used for text-to-speech. There are instructions to make all voices visible.

Searching the text

The viewer has very powerful search capabilities. Press the Ctrl+F key or access the viewer controls and click search. The simplest form of searching is to just search for whatever text you enter in the text box. The different forms of searching are chosen by the search mode box below the search input. Available modes are:

  1. Contains - The simplest default mode. The text entered in the search box is searched for anywhere. All punctuation, accents and spaces are ignored. For example, the search: Pena will match all of the following: penal, pen a, pen.a and Peña. If you select the Case sensitive box then accents, spaces and punctuation are no longer ignored.

  2. Whole words - Searches for whole words. So for example, the search pena will match the word Peña but not the word Penal. As with Contains searches above, accents and punctuation are ignored unless the Case sensitive box is checked.

  3. Nearby words - Searches for whole words that are near each other. So for example, the search calibre cool will match places where the words calibre and cool occur within sixty characters of each other. To change the number of characters add the new number to the end of the list of words. For instance, calibre cool awesome 120 will match places where the three words occur within 120 characters of each other. Note that punctuation and accents are not ignored for these searches.

  4. Regex - Interprets the search text as a regular expression. To learn more about using regular expressions, see the tutorial.

Lugemiskogemuse väljanägemise kohandamine

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 change the number of pages displayed on the screen as well as page margins in Page layout in 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.

Sõnastikust otsimine

You can look up the meaning of words in the current book by double clicking or long tapping the word you want to lookup and then clicking the lookup button that looks like a library.

Teksti ja piltide kopeerimine

Teksti ja pilte saad valida, lohistades hiirega üle sisu ja seejärel paremklõpsates ja valides Kopeeri lõikelauale kopeerimiseks. Kopeeritud materjali saab teise programmi kleepida lihttekstina ja piltidena.

Zooming in on images

You can zoom in to show an image at full size in a separate window by either double clicking or long tapping on it. You can also right click on it and choose View image.

Klaviatuuri otseteed

The viewer has extensive keyboard shortcuts, like the rest of calibre. They can be customised in the viewer Preferences. The default shortcuts are listed below:

Non re-flowable content

Some books have very wide content that cannot be broken up at page boundaries. For example tables or <pre> tags. In such cases, you should switch the viewer to flow mode by pressing Ctrl+M to read this content. Alternately, you can also add the following CSS to the Styles section of the viewer preferences to force the viewer to break up lines of text in <pre> tags:

code, pre { white-space: pre-wrap }

Designing your book to work well with the calibre viewer

The calibre viewer will set the is-calibre-viewer class on the root element. So you can write CSS rules that apply only for it. Additionally, the viewer will set the following classes on the body element:

body.calibre-viewer-dark-colors

Set when using a dark color scheme

body.calibre-viewer-light-colors

Set when using a light color scheme

body.calibre-viewer-paginated

Set when in paged mode

body.calibre-viewer-scrolling

Set when in flow (non-paginated) mode

body.calibre-footnote-container

Set when displaying a popup footnote

Finally, you can use the calibre color scheme colors via CSS variables. The calibre viewer defines the following variables: --calibre-viewer-background-color, --calibre-viewer-foreground-color and optionally --calibre-viewer-link-color in color themes that define a link color.
