Interface 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/ ).
