Syntax
C#
Objective-C
C++/CLI
Java
Python
public BarcodeOutputTextPosition TextPosition { get; set; } 
@property (nonatomic, assign) LTBarcodeOutputTextPosition textPosition; 
public BarcodeOutputTextPosition getTextPosition() 
public void setTextPosition(BarcodeOutputTextPosition value) 
public: 
property BarcodeOutputTextPosition TextPosition { 
   BarcodeOutputTextPosition get(); 
   void set (    BarcodeOutputTextPosition ); 
} 
TextPosition # get and set (FourStateBarcodeWriteOptions) 

Property Value

A BarcodeOutputTextPosition enumeration member that specifies the text position to use when the data string is written along with the barcode. The default value is BarcodeOutputTextPosition.Default.

Remarks

Only BarcodeOutputTextPosition.None and BarcodeOutputTextPosition.Default is currently supported by this write options class.
