Possibilities
Using F-Font is possible to load different embedded fonts inside of a same text Field and also using different styles.
F-Font doesn't change anything in the original textfield except the font type. It means that style Sheets, filters, anti-alias data will not be lost after applied external fonts.
Benchmark
In our tests, F-Font was able to load more than 200 different external fonts inside a SWF document, totalizing more than 2.1 MB of fonts without overload the Flash Player memory and CPU usage.
Is good known that more fonts are loaded, more Flash Player can delay to load the data.
F-Font has a smart logic that download one font per time, (a Queued, as download managers usually do with common downloads) this way is guaranteeing that all fonts will be always loaded.
Compatibility
F-Font component can be exported to Flash Player 7, 8 and 9 using ActionScript 1.0 and 2.0.
* F-Font can be exported to SWF 7 format but Flash Player 8 or above is required.
