Summary
Gets or sets a value that indicates whether to set the linkage bit when writing the barcode.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public bool SetLinkageBit { get; set; } 
@property (nonatomic, assign) BOOL setLinkageBit; 
public boolean getSetLinkageBit() 
public void setSetLinkageBit(boolean value) 
public: 
property bool SetLinkageBit { 
   bool get(); 
   void set (    bool ); 
} 
SetLinkageBit # get and set (GS1DatabarStackedBarcodeWriteOptions) 

Property Value

true to set the linkage bit when writing the barcode. Otherwise, false. The default value is false.

Remarks

Used by both, the stacked and the expanded stacked GS1 Databar barcodes.
