    • getHints

      public Map<EncodeHintType,Object> getHints()
      Returns:
      modifiers to change the way the barcode is created.

    • setHints

      public void setHints (Map<EncodeHintType,Object> hints)
      Parameters:
      hints - modifiers to change the way the barcode is created. They can be EncodeHintType.ERROR_CORRECTION and EncodeHintType.CHARACTER_SET. For EncodeHintType.ERROR_CORRECTION the values can be ErrorCorrectionLevel.L, M, Q, H. For EncodeHintType.CHARACTER_SET the values are strings and can be Cp437, Shift_JIS and ISO-8859-1 to ISO-8859-16. You can also use UTF-8, but correct behaviour is not guaranteed as Unicode is not supported in QRCodes. The default value is ISO-8859-1.
