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 fonts, see the Apple TrueType Reference Manual ( http://fonts.apple.com/TTRefMan/index.html ).

version: 10 Feb 1997
