USING FLASH CS4 PROFESSIONAL
Text
The Flash text rendering engine provides clear, high-quality text rendering in Flash (FLA) documents and published
SWF files. The Anti-alias for Readability setting makes text more legible, particularly at small font sizes. Custom anti-
aliasing lets you specify the thickness and sharpness of fonts used in individual text fields.
High quality anti-aliasing is automatically enabled whenever you publish to Flash Player 8 or later and Anti-Alias For
Readability or Custom Anti-Alias is selected. Anti-Alias For Readability may cause a slight delay when you load Flash
SWF files, especially if you are using four or five different character sets in the first frame of a Flash document. High-
quality anti-aliasing may also increase Flash Player’s memory usage. Using four or five fonts, for example, can increase
memory usage by approximately 4 MB.
When the publish setting of your file is Adobe® Flash® Player 8 or later, and Anti-Alias For Readability or Custom
Anti-
Alias is your chosen anti-aliasing option, high-quality anti-aliasing applies to the following:
•
Untransformed text that is scaled or rotated
Note:
Although the text can be scaled or rotated, it must remain flat (that is, untransformed). For example, if you skew
the fonts or otherwise manipulate the font shapes, Anti-Alias for Readability is automatically disabled.
•
All font families (including bold, italic, and so on)
•
Display sizes of up to 255 points
•
Exporting to most non-Flash file formats (GIF or JPEG)
High-quality anti-aliasing is disabled under the following conditions:
•
Flash Player 7 or earlier is the selected version of Flash Player.
•
An anti-aliasing option other than Anti-Alias for Readability or Custom Anti-Alias is selected.
•
Text is skewed or flipped.
•
The FLA file is exported to a PNG file.

Unicode text encoding in SWF applications
Flash Player 7 and later support Unicode text encoding for SWF files in Flash Player format. This support greatly
enhances your ability to use multilanguage text in your SWF files, such as two languages within a single text field. Any
user with Flash Player 7 or later can view multilanguage text in a Flash Player 7 or later application, regardless of the
language used by the operating system running the player.

Font outlines and device fonts
When you publish or export a Flash document, fonts in text fields are represented by embedded font outlines or by
font names. Alternatively, you can use device fonts to specify a general type of font, such as sans serif.
