    • Constructor Detail

      • CMap

        protected CMap​(short format,
               short language)
        Creates a new instance of CMap Don't use this directly, use CMap.createMap()

    • Method Detail

      • createMap

        public static CMap createMap​(short format,
                             short language)
        Create a map for the given format and language

        The Macintosh standard character to glyph mapping is supported by format 0.

        Format 2 supports a mixed 8/16 bit mapping useful for Japanese, Chinese and Korean.

        Format 4 is used for 16 bit mappings.

        Format 6 is used for dense 16 bit mappings.

        Formats 8, 10, and 12 (properly 8.0, 10.0, and 12.0) are used for mixed 16/32-bit and pure 32-bit mappings.
        This supports text encoded with surrogates in Unicode 2.0 and later.
