using Syncfusion.UI.Xaml.Barcode

SfBarcode sfBarcode = new SfBarcode();
sfBarcode.Value = "Syncfusion";
sfBarcode.Symbology = new QRBarcode();

Constructors

QRBarcode()

Initializes QRBarcode class.

Declaration

public QRBarcode()

Properties

ErrorCorrectionLevel

Declaration

public ErrorCorrectionLevel ErrorCorrectionLevel { get; set; }

Property Value

Type

Description

ErrorCorrectionLevel

The default value is Low. Fields:

Enumeration	Description
Low	Approximately 7% of the codewords can be restored.
Medium	Approximately 15% of the codewords can be restored.
Quartile	Approximately 25% of the codewords can be restored.
High	Approximately 30% of the codewords can be restored.

InputMode

Gets or sets the input mode of QRBarcode in which the data should be encoded

Declaration

Property Value

Type

Description

QRInputMode

The default value is BinaryMode. Fields:

Enumeration	Description
NumericMode	Input will contain only the numeric values [0-9].
AlphaNumericMode	Input may contain [0-9], [A-Z], SPACE, $, %, *, +, -, ., /, :
BinaryMode	Input will contain all ASCII values.

Remarks

This property is applicable only for QRBarcode

QRVersion

Gets or sets the version of QRBarcode to decide on the number of modules that is used to encode the amount of data.

Declaration

public QRBarcodeVersion QRVersion { get; set; }

Property Value

Type	Description
QRBarcodeVersion	The QRBarcode uses version from 1 to 40. Version 1 measures 21 modules x 21 modules, version 2 measures 25 modules x 25 modules, and so on. The number of modules increases in steps of 4 modules per side up to version 40 that measures 177 modules x 177 modules. The default value is Auto.

Remarks

The QRBarcode version's data capacity depends on the amount of data, character type and error correction level
