Class Barcode128

    java.lang.Object
      com.lowagie.text.pdf.Barcode
          com.lowagie.text.pdf.Barcode128

    public class Barcode128

extends Barcode

Implements the code 128 and UCC/EAN-128. Other symbologies are allowed in raw mode.

The code types allowed are:

- CODE128 - plain barcode 128.
- CODE128_UCC - support for UCC/EAN-128 with a full list of AI.
- CODE128_RAW - raw mode. The code attribute has the actual codes from 0 to 105 followed by '\uffff' and the human readable text.

The default parameters are:

     x = 0.8f;
     font = BaseFont.createFont("Helvetica", "winansi", false);
     size = 8;
     baseline = size;
     barHeight = size * 3;
     textAlignment = Element.ALIGN_CENTER;
     codeType = CODE128;

    public Barcode128()

  Creates new Barcode128

Method Detail

### removeFNC1

    public static String removeFNC1(String code)

  Removes the FNC1 codes in the text.

  Parameters:
    `code` - the text to clean
  Returns:
    the cleaned text

### getHumanReadableUCCEAN

    public static String getHumanReadableUCCEAN(String code)

  Gets the human readable text of a sequence of AI.

  Parameters:
    `code` - the text
  Returns:
    the human readable text

### isNextDigits

    static boolean isNextDigits(String text,
                                int textIndex,
                                int numDigits)

  Returns `true` if the next `numDigits` starting from index `textIndex` are numeric skipping any FNC1.

  Parameters:
    `text` - the text to check
    `textIndex` - where to check from
    `numDigits` - the number of digits to check
  Returns:

### setCode

    public void setCode(String code)

  Sets the code to generate. If it's an UCC code and starts with '(' it will be split by the AI. This code in UCC mode is valid:
