This document introduces page thumbnails and describes their capabilities on a Navigation Pane.

This document consists of the following sections.

Expanded Overview

A thumbnail provides a miniature preview of a document page. The PDF Viewer shows page thumbnails of an active PDF document in the Page Thumbnails panel. The panel is located on the Navigation Pane.

When a thumbnail is selected, the PDF Viewer shows the corresponding page.

You can navigate through a document by selecting the page thumbnails.

The Page Thumbnails panel provides thumbnail options that can be accessed using one of the following ways:

  • click the Options drop-down button;

  • use the right click menu of the Page Thumbnails panel.

The Page Thumbnails panel provides the following options.

  • Print Pages... - invokes the Print dialog in which you can print pages that correspond to the selected thumbnails.

    Use this option after a thumbnail is selected. If there are no selected thumbnails in the panel, the Page range option in the Print dialog is set to All. This means that all pages in a document can be printed.

  • Enlarge Page Thumbnails - increases the page thumbnails size.
  • Reduce Page Thumbnails - decreases the page thumbnails size.

You can also enlarge/reduce thumbnail size using one of the following ways:

  • press Ctrl on the keyboard and scroll the mouse wheel when the Page Thumbnails panel is focused;
  • use the zoom slider which is placed on the panel.

Expanded Customization

This section describes properties that can be used to customize thumbnails of a PDF Viewer.
