Increase the magnification of the document view.

Decrease the magnification of the document view.

Zoom the document image to the actual size as prescribed by the document parameters.

Change the magnification of the document view to a value that makes the pages' width equal to the document view's width.

Change the magnification of the document view to a value that, depending on the size relation between the page and the view area, automatically either makes the pages' width equal to the document view's width (like fit-width), the pages' height equal to the document view's height (like fit-height), or the whole page visible (like fit-page).

This submenu makes you choose the view mode for the pages. The possible options are: Single Page (only one page per row), Facing Pages (two pages per row, in a book style), Facing Pages (Center First Page) and Overview (the number of columns is the one specified in the Okular settings).

Additionally, you can enable the Continuous mode. In continuous mode, all pages of the document are shown, and you can smoothly scroll through them. Otherwise, only one page (or one row of pages) is shown at a time.

This submenu allows you to changes the orientation of the pages of the document.

You can select Original Orientation to restore the orientation of the document, discarding all the rotations applied manually.

This submenu allows you to remove the white border of pages when viewing pages (Trim Margins item) or trim viewport to selection (Trim To Selection item).

The “trim to selection” mode allows you to draw a selection over the rendered page in order to define a visible bounding box to be applied to all pages in the document. Selecting a small trim bounding box enforces minimum dimensions size (20% as a percentage of total page size).

The “trim margins” mode is persistent across Okular restarts. The “trim to selection” mode is forgotten across Okular restarts.

When you switch Okular from “trim margins” mode to “trim to selection” mode, the view jumps out of “trim margins” mode for the bounding box selection interaction.

The trim mode can be deactivated by selecting the same menu item that activates it once again.

Show or hides the display of the form fields of the document.
