Embedding and animating fonts in a Flex application

In this example we embed a font (the awesome “Base 02″ PC TrueType font (TTF) from http://www.stereo-type.net/), animate it using the Zoom effect and the Elastic.easeOut easing method. We also set the rotation and alpha properties (which you can’t do with non-embedded fonts), and we set the fontAntiAliasType to “advanced” to give the font a cleaner look. Finally we use the effectEnd event to loop the animation.

<!-- Set zoom effect for 2.5 seconds (2500 milliseconds) and use the

<!-- Use advanced font anti-aliasing for the embedded font,

set the rotation to 5 degrees, alpha to 80% and loop the animation. -->

<mx:Text id="embeddedText" text="The quick brown fox jumped

over the lazy dog." styleName="MyEmbeddedFont" rotation="5" alpha="0.8"

fontAntiAliasType="advanced"

creationComplete="zoom.play();" effectEnd="zoom.play()" />
