The recognition mode adjusts the size of the smallest element in the barcode, ranging from 1 to infinity. This element can be either a matrix cell or a bar:

• Getter XDimensionMode QualitySettings::get_XDimension() const;
• Setter void QualitySettings::set_XDimension(XDimensionMode value);

The minimum size of the XDimension (barcode element width) in pixels, utilized when the XDimensionMode::UseMinimalXDimension used:

• Getter float QualitySettings::get_MinimalXDimension() const;
• Setter void QualitySettings::set_MinimalXDimension(float value);

This mode activates methods to recognize barcode elements based on the chosen quality. Barcode elements with lower quality demand more intensive methods, resulting in slower recognition:

• Getter BarcodeQualityMode QualitySettings::get_BarcodeQuality() const;
• Setter void QualitySettings::set_BarcodeQuality(BarcodeQualityMode value);

Deconvolution mode, used for image restoration, determines the degree of image degradation:

• Getter DeconvolutionMode QualitySettings::get_Deconvolution() const;
• Setter void QualitySettings::set_Deconvolution(DeconvolutionMode value);

This mode allows for the enabling or disabling of additional barcode recognition on images with inverted colors (luminance):

• Getter InverseImageMode QualitySettings::get_InverseImage() const;
• Setter void QualitySettings::set_InverseImage(InverseImageMode value);

This mode allows the enabling or disabling of additional recognition for color barcodes on color images:

• Getter ComplexBackgroundMode QualitySettings::get_ComplexBackground() const;
• Setter void QualitySettings::set_ComplexBackground(ComplexBackgroundMode value);

Quality presets:

• QualitySettings::get_HighPerformance() - This recognition quality preset is optimized for efficiently recognizing high-quality barcodes.
• QualitySettings::get_NormalQuality() - This recognition preset is well-suited for the majority of barcodes, providing a balanced performance.
• QualitySettings::get_HighQuality() - This recognition preset is designed for low-quality barcodes, enabling the detection of highly damaged barcodes.
• QualitySettings::get_MaxQuality() - This recognition preset is developed to recognize all possible barcodes, including potentially incorrect barcodes.

Micro QR and rMQR codes

RectMicroQR barcode type was added to Aspose::BarCode::BarCodeRecognition::DecodeType. RectMicroQR and MicroQR types were added to Aspose::BarCode::Generation::EncodeTypes. New public members were added to the Aspose::BarCode::Generation::QrParameters:

• Getter Aspose::BarCode::Generation::MicroQRVersion get_MicroQRVersion() const;
• Setter void set_MicroQRVersion(Aspose::BarCode::Generation::MicroQRVersion value);
• Getter Aspose::BarCode::Generation::RectMicroQRVersion get_RectMicroQrVersion() const;
• Setter void set_RectMicroQrVersion(Aspose::BarCode::Generation::RectMicroQRVersion value);

Examlpe of RectMicroQR generation and recognition code:

System::String codetext = u"Aspose";
auto generator = System::MakeObject<BarcodeGenerator>(EncodeTypes::RectMicroQR, codetext);

generator->get_Parameters()->get_Barcode()->get_QR()->set_RectMicroQrVersion(RectMicroQRVersion::R11x77);
auto image = generator->GenerateBarCodeImage();
auto reader = System::MakeObject<BarCodeReader>(image, DecodeType::RectMicroQR);

System::Console::WriteLine(System::String(u"Codetext: ") + reader->get_FoundBarCodes()[0]->get_CodeText());

Examlpe of MicroQR generation and recognition code:
