XModule Property

Summary

Gets or sets a value that indicates the size of the smallest module when writing a POSTNET/PLANET barcode.

Syntax

Objective-C

C++/CLI

Java

Python

public int XModule { get; set; }

@property (nonatomic, assign) NSInteger xModule;

public int getXModule() 
public void setXModule(int value)

public: 
property int XModule { 
   int get(); 
   void set (    int ); 
}

XModule # get and set (PostNetPlanetBarcodeWriteOptions)

Property Value

An Int32 that indicates the size of the smallest module when writing a POSTNET/PLANET barcode in thousandths of an inch. Must be a value greater than or equal to 0. The default value is 30 (0.03 of an inch).

Remarks

Only used if the value of UseXModule is set to true, otherwise, the module size is calculated from the data size BarcodeData.Bounds).

If the value is too small, a minimum of 2 pixels will be used regardless of the value set in XModule.

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