Real World Adobe InDesign CS4: Interactive Documents

Article Description

Olav Martin Kvern and David Blatner explain InDesign's features for the “rich media” producer. Many of these tools don’t produce any visible effect on your InDesign pages, but change the behavior of PDF or Flash SWF files that you export.
Page Transitions

Page Transitions

Normally, if you switch from one page to another in your interactive document, the transition is (more or less) instantaneous—like flipping from one channel to the next. But you have the option to spice up your multi-page PDF and SWF files by adding more interesting transitions. The trick (you guessed it) is yet another panel: The Page Transitions panel, which you can find in the Interactive submenu, under the Window menu (see Figure 13-8).

The Page Transitions panel gives you two ways to choose a type of transition: You can pick from the Transition pop-up menu, or you can choose Choose from the panel menu. Both do the same thing, but the latter displays a dialog box that shows you all the transitions at the same time. In either case, you can get a preview of the transition by placing your cursor over the displayed graphic. The transition is applied to the current page.

Most transitions also let you specify one or two parameters, such as which way a wipe wipes or how fast a dissolve dissolves. You can control those in the lower half of the panel.

If you want every page to have the same transition, you can turn on the Apply to All Spreads checkbox in the Page Transitions dialog box, or click the Apply to All Spreads button at the bottom of the panel. You can still override those transitions later on a page-by-page basis if you want.

As with other interactive features, you can only see the page transitions after exporting a SWF or PDF file. In fact, in the case of a PDF, you must remember to enable the Interactive Elements checkbox in the Export PDF dialog box. Plus, you’ll only see the transitions if you’re viewing in Acrobat’s Full Screen Mode.
