Public API changes and backwards compatibility

AustraliaPost, Planet, Postnet barcodes generation

AustraliaPost, Planet, Postnet barcodes generation is changed.

AustralianPost.AustralianPostShortBarHeight by default is set to zero and calculated by default as 0.26 from BarHeight.

//AustraliaPost barcode generation
example1()
{
    let gen = new BarcodeGenerator(EncodeTypes.AUSTRALIA_POST, "6212345678AP");
    gen.getParameters().getBarcode().getAustralianPost().setAustralianPostEncodingTable(CustomerInformationInterpretingType.C_TABLE);
    gen.getParameters().getBarcode().getBarHeight().setPixels(100);
    gen.save(ApiChanges.image_path_to_save1,BarCodeImageFormat.PNG);
}

// If short bar is not specified, it is scaled to 0.26 * BarHeight
example2()
{
    let gen = new BarcodeGenerator(EncodeTypes.AUSTRALIA_POST, "6212345678AP");
    gen.getParameters().getBarcode().getAustralianPost().getAustralianPostShortBarHeight().setPixels(10);
    gen.getParameters().getBarcode().getPadding().getLeft().setPixels(10);
    gen.getParameters().getBarcode().getPadding().getTop().setPixels(10);
    gen.getParameters().getBarcode().getPadding().getRight().setPixels(10);
    gen.getParameters().getBarcode().getPadding().getBottom().setPixels(10);
    gen.save(ApiChanges.image_path_to_save2, BarCodeImageFormat.PNG);
}

Postal.PostalShortBarHeight by default is set to zero and calculated by default as 0.5 from BarHeight.

//Planet, Postnet barcodes generation
example3()
{
    let gen = new BarcodeGenerator(EncodeTypes.POSTNET, "5552357000");
    gen.getParameters().getBarcode().getBarHeight().setPixels(100);
    // If short bar is not specified, it is scaled to 0.5 * BarHeight
    gen.getParameters().getBarcode().getPostal().getPostalShortBarHeight().setPixels(40);
    gen.getParameters().getBarcode().getCodeTextParameters().setLocation(CodeLocation.NONE);
    gen.getParameters().getBarcode().getPadding().getLeft().setPixels(10);
    gen.getParameters().getBarcode().getPadding().getTop().setPixels(10);
    gen.getParameters().getBarcode().getPadding().getRight().setPixels(10);
    gen.getParameters().getBarcode().getPadding().getBottom().setPixels(10);
    gen.save(ApiChanges.image_path_to_save3, BarCodeImageFormat.PNG);
}

PZN7 and PZN8 barcodes generation

PZN8 and PZN7 encoding and decoding are supported:

To encode PZN7 it is needed to provide 6 digits or less to CodeText, like “123456”.
To encode PZN8 it is needed to provide 7 digits or more to CodeText, like “1234567”.
Provided last checksum digit is ignored and generated by the barcode engine.

//Encode and decode PZN7
//When you provide a 6-digit code text to the BarcodeGenerator with EncodeTypes.PZN, 
// the library interprets it as a PZN7 barcode. 
// The PZN7 format consists of 7 digits: 6 data digits plus 1 check digit calculated by the system.
example4()
{
    let gen = new BarcodeGenerator(EncodeTypes.PZN, "123456");
    let reader = new BarCodeReader(gen.generateBarCodeImage(BarCodeImageFormat.PNG), null, DecodeType.PZN);
    let barCodeResults = reader.readBarCodes();
    for (const result of barCodeResults) {
        console.log(result.getCodeTypeName() + ':' + result.getCodeText());
    }
}

//Encode and decode PZN8
//When you provide a 7-digit code text, the library generates a PZN8 barcode. 
// The PZN8 format consists of 8 digits: 7 data digits plus 1 check digit calculated by the system.
example5()
{
    let gen = new BarcodeGenerator(EncodeTypes.PZN, "1234567");
    let reader = new BarCodeReader(gen.generateBarCodeImage(BarCodeImageFormat.PNG), null,DecodeType.PZN);
    let barCodeResults = reader.readBarCodes();
    for (const result of barCodeResults) {
        console.log(result.codeTypeName + ':' + result.codeText);
    }
}

QR, MicroQR, RectMicroQR barcodes recognition

QR, MicroQR, RectMicroQR barcodes recognition parameters obtained new public properties QRVersion, MicroQRVersion, RectMicroQRVersion and QRErrorLevel, which have been added to the QRExtendedParameters.

example6()
{
    let gen = new BarcodeGenerator(EncodeTypes.QR, "Aspose");
    gen.getParameters().getBarcode().getQR().setQrVersion(QRVersion.VERSION_15);
    gen.getParameters().getBarcode().getQR().setQrErrorLevel(QRErrorLevel.LEVEL_M);
    let reader = new BarCodeReader(gen.generateBarCodeImage(BarCodeImageFormat.PNG), null, DecodeType.QR);
    let barCodeResults = reader.readBarCodes();
    for (const result of barCodeResults) {
        console.log("Codetype: " + result.getCodeTypeName());
        console.log("Codetext: " + result.getCodeText());
        console.log("QR version: " + result.getExtended().getQR().getQRVersion());
        console.log("Error level: " + result.getExtended().getQR().getQRErrorLevel());
    }
}

Result:

Codetype: QR
Codetext: Aspose
QR version: VERSION_15
Error level: LEVEL_M
