Hello Team,

We are using Google Zxing library to generate barcode. The barcodes are generating fine but we couldn't include  FNC1 (hidden character) to make to GS1 required format. 

The below is the code,

com.google.zxing.oned.Code128Writer writer = new com.google.zxing.oned.Code128Writer(); com.google.zxing.common.BitMatrix matrix = null;

try  {    matrix = writer.encode(qrtext, com.google.zxing.BarcodeFormat.CODE_128, width, height); }

catch (com.google.zxing.WriterException e) { throw new PRRuntimeException(e); }

java.awt.image.BufferedImage image = new java.awt.image.BufferedImage(width, height, java.awt.image.BufferedImage.TYPE_INT_RGB);

image.createGraphics();

The image object will be converted into png type and will be uploaded in the image content rule.

Can you please share the details if any one generating barcode according GS1 format by using Google Zxing or any other open source library?

Thanks in advance.

Regards,

Satish
