Member Function Documentation

◆ get_AustraliaPost()

System::SharedPtr<AustraliaPostSettings> Aspose::BarCode::BarCodeRecognition::BarcodeSettings::get_AustraliaPost ( )

Gets AustraliaPost decoding parameters

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

◆ get_ChecksumValidation()

Aspose::BarCode::BarCodeRecognition::ChecksumValidation Aspose::BarCode::BarCodeRecognition::BarcodeSettings::get_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
