setChecksumValidation

setChecksumValidation(value)

Enable checksum validation during recognition for 1D and Postal barcodes. Default is treated as Yes for symbologies which must contain checksum, as No where checksum only possible. Checksum never used: Codabar, PatchCode, Pharmacode, DataLogic2of5 Checksum is possible: Code39 Standard/Extended, Standard2of5, Interleaved2of5, ItalianPost25, Matrix2of5, MSI, ItalianPost25, DeutschePostIdentcode, DeutschePostLeitcode, VIN Checksum always used: Rest symbologies

Parameter	Description
value	Enable checksum validation during recognition for 1D and Postal barcodes.

Example:

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());
