Anti-aliasing lets you smooth the edges of onscreen text. The anti-aliasing options are particularly effective for rendering smaller font sizes. When anti-aliasing is enabled, all text in the current selection is affected. Anti-aliasing operates with text of all point sizes in the same way.
Anti-aliasing is supported for static, dynamic, and input text if the user has Flash Player 7 or later. It is supported only for static text if the user has an earlier version of Flash Player.
When using small text in a Flash document, keep in mind the following guidelines:
Sans serif text, such as Helvetica or Arial, appears clearer at small sizes than serif text.
Some type styles, such as bold and italic, can make text less legible at small sizes.
In some cases, text appears somewhat smaller than text of the same point size in other applications.
