Text Layout Framework Technology Center

The Text Layout Framework is an extensible Adobe ActionScript library built on the new text engine introduced in Adobe Flash Player 10 that delivers advanced, easy-to-integrate typographic and text layout features for rich, sophisticated, and innovative typography on the web. The framework is designed to be used with Adobe Flash CS4 Professional and later or Adobe Flex and is already included in Flex 4 and later. Developers can use or extend existing components or use the framework to create their own text components.
The Text Layout Framework is available as open-source software.
