ErrorCorrectionRate Property

Summary

Gets or sets the error detection and correction ratio when writing an Aztec barcode.

Syntax

Objective-C

C++/CLI

Java

Python

public int ErrorCorrectionRate { get; set; }

@property (nonatomic, assign) NSInteger errorCorrectionRate;

public int getErrorCorrectionRate() 
public void setErrorCorrectionRate(int value)

public: 
property int ErrorCorrectionRate { 
   int get(); 
   void set (    int ); 
}

ErrorCorrectionRate # get and set (AztecBarcodeWriteOptions)

Property Value

An Int32 to be used when writing an Aztec barcode. Must be a value greater than or equal to 5 and less than or equal 95. The default value is 23.

Remarks

This value indicates the minimum ratio of codewords to be used as error detection and correction codewords, knowing that any extra codewords after encoding the message will be used as error detection and correction codewords.
