      Parameters:
      document - The document to which the barcode will be added

    • Barcode128

      public Barcode128(PdfDocument document, PdfFont font)
      Creates new Barcode128, which will use the provided font
      Parameters:
      document - The document to which the barcode will be added
      font - The font to use

    • getRawText

      public static String getRawText(String text, boolean ucc, Barcode128.Barcode128CodeSet codeSet)
      Converts the human readable text to the characters needed to create a barcode using the specified code set.
      Parameters:
      text - the text to convert
      ucc - true if it is an UCC/EAN-128. In this case the character FNC1 is added
      codeSet - forced code set, or AUTO for optimized barcode.
      Returns:
      the code ready to be fed to getBarsCode128Raw()

    • getRawText

      public static String getRawText(String text, boolean ucc)
      Converts the human readable text to the characters needed to create a barcode. Some optimization is done to get the shortest code.
      Parameters:
      text - the text to convert
      ucc - true if it is an UCC/EAN-128. In this case the character FNC1 is added
      Returns:
      the code ready to be fed to getBarsCode128Raw()

    • getBarsCode128Raw

      public static byte[] getBarsCode128Raw(String text)
      Generates the bars. The input has the actual barcodes, not the human readable text.

      Returns:
      the bars

    • getBarcodeSize

      public Rectangle getBarcodeSize()
