    • convertToBytes

      public static final byte[] convertToBytes(String text, String encoding)
      Deprecated.
      Converts a String to a byte array according to the font's encoding.
      Parameters:
      text - the String to be converted
      encoding - the encoding
      Returns:
      an array of byte representing the conversion according to the font's encoding

    • convertToBytes

      public static final byte[] convertToBytes(char char1, String encoding)
      Deprecated.
      Converts a String to a byte array according to the font's encoding.
      Parameters:
      char1 - the char to be converted
      encoding - the encoding
      Returns:
      an array of byte representing the conversion according to the font's encoding

    • convertToString

      public static final String convertToString(byte[] bytes, String encoding)
      Deprecated.
      Converts a byte array to a String according to the some encoding.
      Parameters:
      bytes - the bytes to convert
      encoding - the encoding
      Returns:
      the converted String

    • isPdfDocEncoding

      public static boolean isPdfDocEncoding(String text)
      Deprecated.
      Checks is text only has PdfDocEncoding characters.
      Parameters:
      text - the String to test
      Returns:
      true if only PdfDocEncoding characters are present

    • clearCmap

      public static void clearCmap(String name)
      Deprecated.
      Clears the CJK cmaps from the cache. If name is the empty string then all the cache is cleared. Calling this method has no consequences other than the need to reload the cmap if needed.
      Parameters:
      name - the name of the cmap to clear or all the cmaps if the empty string

    • loadCmap

      public static void loadCmap(String name, byte[][] newline)
      Deprecated.
      Loads a CJK cmap to the cache with the option of associating sequences to the newline.
      Parameters:
      name - the CJK cmap name
      newline - the sequences to be replaced by a newline in the resulting CID. See CRLF_CID_NEWLINE

    • convertCmap

      public static String convertCmap(String name, byte[] seq)
      Deprecated.
      Converts a byte array encoded as name to a CID string. This is needed to reach some CJK characters that don't exist in 16 bit Unicode.

      The font to use this result must use the encoding "Identity-H" or "Identity-V".

      See ftp://ftp.oreilly.com/pub/examples/nutshell/cjkv/adobe/.
      Parameters:
      name - the CJK encoding name
      seq - the byte array to be decoded
      Returns:
      the CID string

    • convertCmap

      public static String convertCmap(String name, byte[] seq, int start, int length)
      Deprecated.
      Converts a byte array encoded as name to a CID string. This is needed to reach some CJK characters that don't exist in 16 bit Unicode.

      The font to use this result must use the encoding "Identity-H" or "Identity-V".

      See ftp://ftp.oreilly.com/pub/examples/nutshell/cjkv/adobe/.
      Parameters:
      name - the CJK encoding name
      seq - the byte array to be decoded
      start - the start offset in the data
      length - the number of bytes to convert

    • addExtraEncoding

      public static void addExtraEncoding(String name, ExtraEncoding enc)
      Deprecated.
      Adds an extra encoding.
      Parameters:
      name - the name of the encoding. The encoding recognition is case insensitive
      enc - the conversion class
