Enum Class ChecksumValidation

java.lang.Object

java.lang.Enum<ChecksumValidation>

com.aspose.barcode.barcoderecognition.ChecksumValidation

All Implemented Interfaces:

Serializable, Comparable<ChecksumValidation>, Constable

public enum ChecksumValidation
extends Enum<ChecksumValidation>

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

 This sample shows influence of ChecksumValidation on recognition quality and results
 
 BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.EAN_13, "1234567890128");
 {
     generator.save("test.png");
 }
 BarCodeReader reader = new BarCodeReader("test.png", DecodeType.EAN_13))
 {
     //checksum disabled
     reader.getBarcodeSettings().setChecksumValidation(ChecksumValidation.OFF);
     for(BarCodeResult result : reader.readBarCodes())
     {
         System.out.println("BarCode CodeText: " + result.getCodeText());
         System.out.println("BarCode Value: " + result.getExtended().getOneD().getValue());
         System.out.println("BarCode Checksum: " + result.getExtended().getOneD().getCheckSum());
     }
 }
 BarCodeReader reader = new BarCodeReader("test.png", DecodeType.EAN_13);
 //checksum enabled
 reader.getBarcodeSettings().setChecksumValidation(ChecksumValidation.ON);
 for(BarCodeResult result : reader.readBarCodes())
 {
    System.out.println("BarCode CodeText: " + result.getCodeText());
    System.out.println("BarCode Value: " + result.getExtended().getOneD().getValue());
    System.out.println("BarCode Checksum: " + result.getExtended().getOneD().getCheckSum());

Method Details

values

public static ChecksumValidation[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static ChecksumValidation valueOf(String name)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
