As we said at the start of the chapter, if you really want cool SWF files, you’re going to need Adobe Flash CS4 Professional. But you can still use your InDesign layouts—just export them to the Flash interchange format, XFL. When you do this, you’ll see the Export Adobe Flash CS4 Professional (XFL) dialog box (see Figure 13-10).
Figure 3.10 XFL Export Options
Most of the features are the same as the options for creating SWF files—including Scale, Pages, Spreads, Rasterize Pages, and Text. Flatten Transparency requires explanation, though. Flash does not share the same transparency engine with InDesign, so transparent objects may look very different after you open the XFL in Flash. If the look of the object is more important than your ability to animate it in Flash, you can turn on the Flatten Transparency checkbox.
Many people are surprised when they open the XFL in Adobe Flash CS4 Professional because it’s not immediately useful. In fact, you get less than if you exported a SWF from InDesign, as there are no page transitions, no buttons, and no hyperlinks. Instead, you just get one frame per InDesign page (or spread).
