Class 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;

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

      • getRawText

        public static java.lang.String getRawText​(java.lang.String text,
