    - #### encode

          BitMatrix encode(String contents,
                           BarcodeFormat format,
                           int width,
                           int height)
                    throws WriterException

      Encode a barcode using the default settings.
      Parameters:
        `contents` - The contents to encode in the barcode
        `format` - The barcode format to generate
        `width` - The preferred width in pixels
        `height` - The preferred height in pixels
      Returns:
        `BitMatrix` representing encoded barcode image
      Throws:
        `WriterException` - if contents cannot be encoded legally in a format

                           int height,
                           Map<EncodeHintType,?> hints)
                    throws WriterException

      Parameters:
        `contents` - The contents to encode in the barcode
        `format` - The barcode format to generate
        `width` - The preferred width in pixels
        `height` - The preferred height in pixels
        `hints` - Additional parameters to supply to the encoder
      Returns:
        `BitMatrix` representing encoded barcode image
      Throws:
        `WriterException` - if contents cannot be encoded legally in a format
