UseXModule Property

Summary
Gets or sets a value that indicates whether to use the XModule when writing barcodes of this type.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public bool UseXModule { get; set; } 
@property (nonatomic, assign) BOOL useXModule; 
public boolean getUseXModule() 
public void setUseXModule(boolean value) 
public: 
property bool UseXModule { 
   bool get(); 
   void set (    bool ); 
} 
UseXModule # get and set (PostNetPlanetBarcodeWriteOptions) 

Property Value

true to use XModule when writing barcodes of this type. Otherwise, false. The default value is false.

Remarks

When the value of UseXModule is set to false, then the smallest module size is calculated from the size of the barcode data (BarcodeData.Bounds).

When the value of UseXModule is set to true, then the smallest module size is set in XModule and the barcode data size may be used as a "clipping" boundary.

For more information, refer to Writing Barcodes - Bounds and XModule.
