Java: Generate EAN-13 1D format code

Below snippet generate EAN-13 1d format code.

Map<EncodeHintType, ErrorCorrectionLevel> hashMap = new HashMap<EncodeHintType, ErrorCorrectionLevel>();
hashMap.put(EncodeHintType.ERROR_CORRECTION, ErrorCorrectionLevel.H);

BitMatrix bitMatrix = new MultiFormatWriter().encode(new String(message.getBytes(encodingFormat)),BarcodeFormat.EAN_13, imageWidth, imageHeight);

String fileFormat = filePath.substring(filePath.lastIndexOf('.') + 1);
MatrixToImageWriter.writeToPath(bitMatrix, fileFormat, Paths.get(filePath));

 

Find the below working application.
