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/ ).
