64 Working with Flash Documents
Speeding up document display
To speed up the document display, you can use commands in the View menu to turn off
rendering-quality features that require extra computing and slow down document display.
None of these commands have any effect on how Flash exports a document. To specify the
display quality of Flash documents in a web browser, you use the
object
and
embed
parameters. The Publish command can do this for you automatically. For more information,
see
“Publishing Flash documents” on page 459 .
To change the document display speed:
■
Select View > Preview Mode, and select from the following options:
Outlines
displays only the outlines of the shapes in your scene and causes all lines to
appear as thin lines. This makes it easier to reshape your graphic elements and to display
complex scenes quickly.
Fast turns off anti-aliasing and displays all the colors and line styles of your drawing.
Antialias turns on anti-aliasing for lines, shapes, and bitmaps. It displays shapes and lines
so that their edges appear smoother on the screen. This option draws more slowly than the
Fast option. Anti-aliasing works best on video cards that provide thousands (16-bit) or
millions (24-bit) of colors. In 16- or 256-color mode, black lines are smoothed, but colors
might look better in Fast mode.
Antialias Text smooths the edges of any text. This command works best with large font
sizes and can be slow with large amounts of text. This is the most common mode in which
to work.
Full renders all content on the Stage fully. This setting may slow down display.
Optimizing Flash documents
As your document file size increases, so does its download time and playback speed. You can
take several steps to prepare your document for optimal playback. As part of the publishing
process, Flash automatically performs some optimization on documents: for example, it
detects duplicate shapes on export and places them in the file only once, and it converts
nested groups into single groups.
Before exporting a document, you can optimize it further by using various strategies to reduce
the file size. You can also compress a SWF file as you publish it. (See
Chapter 17,
“Publishing,” on page 455 .) As you make changes, it’s a good idea to test your document by
running it on a variety of computers, operating systems, and Internet connections.
