Embedding a font in Flex
You can embed fonts in a Flex application in many ways, including:
Using the [Embed] metadata tag in a script
Using the @font-face style declaration
Establish a class for the font and use the [Embed] tag to embed it.
You can only embed TrueType fonts directly in a Flex application. Fonts in other formats, such as Type 1 Postscript
fonts, can first be embedded in a SWF file using Flash Professional and then that SWF file can be used in your Flex
application. For more details about using embedded fonts from SWF files in Flex, see “Embedding fonts from SWF
files” in Using Flex 4.

settings. You can override Flash Player or AIR settings using the flash.text.TextRenderer class and its associated
classes, like the CSMSettings class. These classes give you precise control over the rendering quality of embedded text.
For more information about embedded fonts, see “Using embedded fonts” on page 384.

TextRenderer.setAdvancedAntiAliasingTable() method.
The following example applies custom continuous stroke modulation (CSM) properties and formatting to displayed
text using an embedded font called myFont. When the user clicks the displayed text, Flash Player or Adobe AIR applies
the custom settings:
