TextPosition Property

Summary
Gets or sets a value that specifies the text position to use when the data string is written along with the barcode.
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 (OneDBarcodeWriteOptions) 

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

Not all symbologies supported by this write options class support all output text position values. Some symbologies allow you to control the text position completely (none, default or top), some will only let you specify whether the text is written or not but not the location (default or none), and others will always require the text to be written (default). Refer to the Barcode symbology standard you are interested in or try it with the C# Barcode demo.
