Flash export issues
Consider the following factors when designing
your InDesign document for Flash playback.
Document setup issues- How InDesign pages are converted
- When you export to SWF or XFL, InDesign spreads become separate
clips in a timeline, like slides in a slideshow. Each spread is
mapped to a new keyframe. In Flash Player, you advance through the spreads
of the exported document by pressing arrow keys or clicking interactive buttons.
 Determine whether you want your InDesign document
to include facing pages. In some instances, it’s better to create
the document without facing pages (deselect the Facing Pages option
in the New Document dialog box). Although you can deselect the Spreads
option during export to SWF to map each page to a keyframe rather
than the whole spread, deselecting Facing Pages simplifies matters. - Page size
- When you create a document, you can choose a specific resolution, such
as 800 x 600, from the Page Size menu in the New Document dialog
box. During export, you can also adjust the scale or resolution
of the exported SWF or XFL file.
Interactivity featuresButtons, page transitions,
and hyperlinks are included in exported SWF files. With exported
XFL files, use Flash Pro to add animation and other effects.
- Buttons
- For buttons in an exported SWF file, the Next Page and Previous
Page actions are especially useful controls for playback in Flash
Player. However, some actions that work in interactive PDF files
have no effect in Flash Player. These actions include Close, Exit,
Go To Next/Previous View, Movie, Open File, Sound, and View Zoom.
Although
button actions are not included in an exported XFL file, you can
add buttons to your layout in InDesign and use Flash Pro to make
them dynamic.
- Page Transitions
- All page transitions work well in Flash Player. In addition
to page transitions that appear when you turn the page, you can
add include an interactive page curl during export that lets you
drag corners of pages to turn them.
- Hyperlinks
- Create links to websites or to other pages in the document.
Hyperlinks are broken in XFL files.
- Movies and sound clips
- Movies and sound clips are not included in an exported SWF
or XFL file, but their posters are included. You can add media posters
to your layout in InDesign, export the document to XFL, and use
Flash Pro to make them dynamic.
Conversion issues- Color
- SWF and XFL files use RGB color. When a document is exported
to SWF or XFL, InDesign converts all color spaces (such as CMYK
and LAB) to sRGB. InDesign converts spot colors to equivalent RGB
process colors.
To avoid unwanted color changes in artwork
with text with transparency, choose Edit > Transparency Blend
Space > Document RGB. To avoid unwanted color changes
in images with transparency, avoid using a lossy compression during export.
- 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.
