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;
