Syntax
public class QRCode : SymbologyBase
Remarks

It can efficiently store more information in a smaller space than 1D barcodes. Each barcode can store values up to 7089 characters. It is mostly used for URLs, business cards, contact information, etc.

The QRCode consists of a grid of dark and light dots or blocks that form a square.

Properties

CodeVersion

Gets or sets a value to define the version that is used to encode the amount of data.

Declaration
public QRCodeVersion CodeVersion { get; set; }
Property Value
Type Description
QRCodeVersion

The default value is Auto.
Remarks

The QRCode 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.

Examples
<barcode:SfBarcodeGenerator Value="123456" ShowText="True">
   <barcode:SfBarcodeGenerator.Symbology>
      <barcode:QRCode CodeVersion="Version01"/>

ErrorCorrectionLevel

Gets or sets a value to define the encode recovery capacity of the barcode.

Declaration
public ErrorCorrectionLevel ErrorCorrectionLevel { get; set; }
Property Value
Type Description
ErrorCorrectionLevel

The default value is Auto.
Remarks

Auto - calculates the error correction level based on the code version and input mode.

Below error correction capability at each of the four levels:

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.

Examples
<barcode:SfBarcodeGenerator Value="123456" ShowText="True">
   <barcode:SfBarcodeGenerator.Symbology>
      <barcode:QRCode ErrorCorrectionLevel="Low"/>
   </barcode:SfBarcodeGenerator.Symbology>
 </barcode:SfBarcodeGenerator>
