XModule Property

Summary

Gets or sets a value that indicates the size of the smallest module when writing a MicroQR 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 (MicroQRBarcodeWriteOptions)

Property Value

An Int32 that indicates the size of the smallest module when writing a MicroQR barcode in a thousandth of an inch. Must be a value greater to or equal to 0. Default value is 30 (0.03 of an inch). The default value is 10.

Remarks

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.
