Interleaved 2 of 5 Barcode - Increase string size in parameter

Question

Good morning, my friends!

I’m having a problem when passing the String with the bar code in the parameter of Barcodeinter25 , In this code is working but if I pass "23797685200000345000280090000014189301107610" it generates an exception of java.lang.Illegalargumentexception: The text length must be Even.

And I’ve looked for several types and I don’t think it’s ideal, since my project needs to generate a bank ticket with 44 positions of the ITF format.

 public static void main(String[] args) {
            Document document = new Document(PageSize.A4, 50, 50, 50, 50);
            try {
                PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("d:\\BarcodesInter25.pdf"));
                document.open();
                PdfContentByte cb = writer.getDirectContent();

                BarcodeInter25 code25 = new BarcodeInter25();
                code25.setGenerateChecksum(true);
                code25.setCode("99-1234567890-001");
                Image image25 = code25.createImageWithBarcode(cb, null, null);

                document.add(new Phrase(new Chunk(image25, 0, 0)));
            }
            catch (Exception de) {
                de.printStackTrace();
            }
            document.close();
      }

Thank you !

"The text length must be Even." It means that the amount of numbers you must pass on has to be odd. This is a problem we have with these ready-made libraries. It does not accept that you pass the type checker. But if you don’t pass, it generates the wrong code without the digit. The way is to do everything by hand, observing the instructions given by the bank to generate the check digit in the correct position, because in the digitable line it is in a different position than printed in the bar code. You have to create your own bar, converting value, maturity, originator code, etc...
