      Modifier and Type Method Description
      static boolean canHandleEncoding​(java.lang.String pdfEncodingName)  
      boolean isMultiByte()
      Returns true if the encoding consumes more than single byte for a character.
      int mapBytesToChars​(byte[] inbytes, int offset, int length, char[] outchars)
      The workhorse.
      int mapCharsToGIDs​(char[] cidbuffer, int ncids, int[] gidbuffer)
      Does the cid->gid mapping, if it knows how.
      int maximumOutputBufferSize​(byte[] inbytes, int offset, int length)
      Quickly returns the maximum number of chars that could result from the conversion of inbytes bytes according to the encoding.
      void setCIDToGIDMap​(java.lang.Object mapobj)
      For CID fonts that know how to map their cids directly into glyph indices.
      boolean supportsCIDToGIDMapping()
      Returns true if encoding knows how to convert to glyph indices.

      • isMultiByte

        public boolean isMultiByte()
        Description copied from class: GlyphMapper
        Returns true if the encoding consumes more than single byte for a character. Note that encodings that sometimes maps single bytes, but other times maps more than one, should always return true for this routine.

      • maximumOutputBufferSize

        public int maximumOutputBufferSize​(byte[] inbytes,
                                   int offset,
                                   int length)
        Description copied from class: GlyphMapper
        Quickly returns the maximum number of chars that could result from the conversion of inbytes bytes according to the encoding. A single byte encoding, like the latin ones, will take a single byte and convert it into a single char, so this routine would just return len. An encoding that takes 2 bytes and converts them to a char would return len/2, etc.

      • mapBytesToChars

        public int mapBytesToChars​(byte[] inbytes,
                           int offset,
                           int length,
                           char[] outchars)
        Description copied from class: GlyphMapper
        The workhorse. Take an input buffer and convert everything. The output buffer should be allocated using the size from the above routine. The actual number of chars in the final output is returned.

        Description copied from class: GlyphMapper
        Does the cid->gid mapping, if it knows how. Returns the total number of glyphs created.
