getAustraliaPost()

Gets AustraliaPost decoding parameters

Returns: The AustraliaPost decoding parameters which make influence on recognized data of AustraliaPost symbology

getChecksumValidation()

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

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);
reader.readBarCodes().forEach(function(result, i, results)
{
     console.log ("BarCode CodeText: ".result.getCodeText());
     console.log ("BarCode Value: " + result.getExtended().getOneD().getValue());
     console.log ("BarCode Checksum: " + result.getExtended().getOneD().getCheckSum());
});
let reader = new BarCodeReader("c:/test.png", DecodeType.EAN_13);
//checksum enabled
reader.getBarcodeSettings().setChecksumValidation(ChecksumValidation.ON);
reader.readBarCodes().forEach(function(result, i, results)
{
     console.log ("BarCode CodeText: " + result.CodeText);
     console.log ("BarCode Value: " + result.getExtended().getOneD().getValue());
     console.log ("BarCode Checksum: " + result.getExtended().getOneD().getCheckSum());
});

Returns: Enable checksum validation during recognition for 1D and Postal barcodes.

getDetectEncoding()

The flag which force engine to detect codetext encoding for Unicode codesets. Default value is true.

Example

let generator = new BarcodeGenerator(EncodeTypes.QR, "Слово"))
$im = generator.generateBarcodeImage(BarcodeImageFormat.PNG);

//detects encoding for Unicode codesets is enabled
let reader = new BarCodeReader(im, DecodeType.QR);
reader.getBarcodeSettings().setDetectEncoding(true);
reader.readBarCodes().forEach(function(result, i, results)
{
    console.log ("BarCode CodeText: ".result.getCodeText());
});
//detect encoding is disabled
let reader = new BarCodeReader(im, DecodeType.QR);
reader.getBarcodeSettings().setDetectEncoding(false);
reader.readBarCodes().forEach(function(result, i, results)
console.log ("BarCode CodeText: " + result.getCodeText());

Returns: The flag which force engine to detect codetext encoding for Unicode codesets

getStripFNC()

Strip FNC1, FNC2, FNC3 characters from codetext. Default value is false.

Example

let generator = new BarcodeGenerator(EncodeTypes.GS_1_CODE_128, "(02)04006664241007(37)1(400)7019590754");
generator.save("c:/test.png", BarcodeImageFormat.PNG);
let reader = new BarCodeReader("c:/test.png", DecodeType.CODE_128);

//StripFNC disabled
reader.getBarcodeSettings().setStripFNC(false);
reader.readBarCodes().forEach(function(result, i, results)
{
    console.log ("BarCode CodeText: ".result.getCodeText());
});

let reader = new BarCodeReader("c:/test.png", DecodeType.CODE_128);

//StripFNC enabled
reader.getBarcodeSettings().setStripFNC(true);
reader.readBarCodes().forEach(function(result, i, results)
{
    console.log ("BarCode CodeText: ".result.getCodeText());
});

Returns: Strip FNC1, FNC2, FNC3 characters from codetext. Default value is false.

setChecksumValidation(value)

let reader = new BarCodeReader("c:/test.png", DecodeType.EAN_13);
//checksum disabled
reader.getBarcodeSettings().setChecksumValidation(ChecksumValidation.OFF);
reader.readBarCodes().forEach(function(result, i, results)
{
     console.log ("BarCode CodeText: ".result.getCodeText());
     console.log ("BarCode Value: " + result.getExtended().getOneD().getValue());
     console.log ("BarCode Checksum: " + result.getExtended().getOneD().getCheckSum());
});
let reader = new BarCodeReader("c:/test.png", DecodeType.EAN_13);
//checksum enabled
reader.getBarcodeSettings().setChecksumValidation(ChecksumValidation.ON);
reader.readBarCodes().forEach(function(result, i, results)
{
     console.log ("BarCode CodeText: " + result.CodeText);
     console.log ("BarCode Value: " + result.getExtended().getOneD().getValue());
