OpenType

```
public interface OpenType
```
The OpenType interface represents OpenType and TrueType fonts. This interface makes it possible to obtain sfnt tables from the font. A particular Font object can implement this interface.
For more information on TrueType and OpenType fonts, see the OpenType specification. ( http://www.microsoft.com/typography/otspec/l ).
