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.

from asposebarcode.Generation import EncodeTypes,CustomerInformationInterpretingType,BarCodeImageFormat,BarcodeGenerator,CodeLocation,QRVersion,QRErrorLevel
from asposebarcode.Recognition import BarCodeReader,DecodeType
#AustraliaPost barcode generation
def testExample1(self):
    gen = BarcodeGenerator(EncodeTypes.AUSTRALIA_POST, "6212345678AP")
    gen.getParameters().getBarcode().getAustralianPost().setAustralianPostEncodingTable(CustomerInformationInterpretingType.C_TABLE)
    gen.getParameters().getBarcode().getBarHeight().setPixels(100)
    gen.save(self.image_path_to_save1, BarCodeImageFormat.PNG)

# If short bar is not specified, it is scaled to 0.26 * BarHeight
def testExample2(self):
    gen = 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(self.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
def testExample3(self):
    gen = 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(self.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.
def testExample4(self):
    gen = BarcodeGenerator(EncodeTypes.PZN, "123456")
    reader = BarCodeReader(gen.generateBarCodeImage(), None, DecodeType.PZN)
    results = reader.readBarCodes()
    for result in results:
        print(f"\nBarCode Type: {result.getCodeTypeName()}")
        print(f"BarCode CodeText: {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.
def testExample5(self):
    gen = BarcodeGenerator(EncodeTypes.PZN, "1234567")
    reader = BarCodeReader(gen.generateBarCodeImage(), None, DecodeType.PZN)
    results = reader.readBarCodes()
    for result in results:
        print(f"\nBarCode Type: {result.getCodeTypeName()}")
        print(f"BarCode CodeText: {result.getCodeText()}")

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.

def testExample6(self):
gen = BarcodeGenerator(EncodeTypes.QR, "Aspose")
gen.getParameters().getBarcode().getQR().setQrVersion(QRVersion.VERSION_15)
gen.getParameters().getBarcode().getQR().setQrErrorLevel(QRErrorLevel.LEVEL_M)
reader = BarCodeReader(gen.generateBarCodeImage(), None, DecodeType.QR)
results = reader.readBarCodes()
for result in results:
    print(f"\nCodetype: {result.getCodeTypeName()}")
    print(f"Codetext: {result.getCodeText()}")
    print(f"QR version:  {result.getExtended().getQR().getQRVersion()}")
    print(f"Error level:  {result.getExtended().getQR().getQRErrorLevel()}")

Result:

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