GS1toHRI Property

Summary

Gets or sets a value indicating whether the Datamatrix reader will format the resulting string in human readable interpretation (HRI).

Syntax

Objective-C

C++/CLI

Python

public bool GS1toHRI { get; set; }

@property (nonatomic, assign) BOOL GS1toHRI;

public: 
property bool GS1toHRI { 
   bool get(); 
   void set (    bool ); 
}

GS1toHRI # get and set (DatamatrixBarcodeReadOptions)

Property Value

true to format the resulting string in human readable interpretation (HRI), add parenthesis around AIs, after reading a GS1 formatted string. Otherwise, false. The default value is false.

Remarks

If the resulting string is needed in GS1 format then there is no need to enable this option.
