Examples

let generator = new BarcodeGenerator(EncodeTypes.EAN_13, "1234567890128");
generator.save("c:/test.png", BarcodeImageFormat.PNG);
let reader = new BarCodeReader("c:/test.png", DecodeType.EAN_13);
//checksum disabled
reader.getBarcodeSettings().setChecksumValidation(ChecksumValidation.OFF);
let results = reader.readBarCodes();
for(let i = 0; i < results.length; i++)
{
let result = results[i];
console.log ("BarCode CodeText: " + result.getCodeText());
console.log ("BarCode Value: " + result.getExtended().getOneD().getValue());
console.log ("BarCode Checksum: " + result.getExtended().getOneD().getCheckSum());
}
