Dynamic documents
Text When exporting to SWF or XFL, you can determine whether text is output as Flash text, vector paths, or
rasterized text. Text exported as Flash text remains fully editable when the XFL file is opened in Adobe Flash CS4
Professional and can be searched in web browsers when saved as SWF files.
Images When you export images to SWF, you can change image compression, JPEG quality, and curve quality settings
during export.
When you export images to XFL, images are exported as PNG files without compression. An image placed multiple
times in your InDesign document is saved as a single image asset with a shared location when exported as an XFL file.
Note that a large number of vector images in the InDesign document may cause performance problems in the exported
file.
To reduce file size, place repeating images on master pages, and avoid copying and pasting images. If the same image
is placed multiple times in the document and not transformed or cropped, only one copy of the file is exported in the
XFL file. Images that are copied and pasted are treated as separate objects.
By default, a placed Illustrator file is treated as a single image in the XFL file, whereas an Illustrator file that’s copied
and pasted generates many individual objects. For best results, place the Illustrator image as a PDF file instead of
copying and pasting from Illustrator. Copying and pasting results in multiple editable paths.
You can change preference options to make sure that Illustrator objects are pasted as one object instead of a collection
of small vectors. In Illustrator File Handling & Clipboard preferences, select PDF and deselect AICB (No
Transparency Support). In InDesign Clipboard Handling preferences, select both Prefer PDF When Pasting and Copy
PDF To Clipboard.
Resolution InDesign automatically converts high-resolution print assets to low-resolution web assets upon export to
SWF or XFL.
Transparency Before exporting to SWF, make sure that transparent objects do not overlap any interactive element,
such as a button or hyperlink. If an object with transparency overlaps an interactive element, the interactivity may be
lost during export. You may want to flatten transparency before exporting to XFL.
In some instances, choosing a lossy compression reduces the quality of images with transparency. When exporting,
choose Lossless (Do Nothing) to improve the quality.
Dynamic PDF documents
Creating a dynamic PDF document is a good way to create an interactive slideshow. You can create interactive
documents with buttons, movies and sound clips, hyperlinks, bookmarks, and page transitions. You can also set up
documents in InDesign that can be converted to forms in Acrobat.
Creating interactive documents for PDF
You can export Adobe PDF documents that include the following interactive features.
Bookmarks Bookmarks you create in the InDesign document appear in the Bookmarks tab on the left side of the
Adobe Acrobat or Adobe Reader window. Each bookmark jumps to a page, text, or graphic in the exported PDF file.
See “
Bookmarks ” on page 524.
Movies and sound clips You can add movies and sound clips to a document, or you can link to streaming video files
on the Internet. These movies and sound clips can be played back in the exported PDF file. See “ Movies and sounds ”
on page 539.
