Hello everyone, Cycle-IT has release a native AIR application, called Antialiaser. Antialiaser is a free AIR application that makes OpenType and TrueType font visualization easy, allowing you to customize them precisely so you can use them inside your Flex 3 and AIR projects.
We've been internally using it, and we decided to release it free. We're working hard to release a new version that supports Flex 4 text controls and font embedding, but for now, if you're still working with Flex 3 projects (new or legacy ones), do not hesitate and give Antialiaser a try.
