Granularity Property

Summary
Gets or sets a value that indicate the number of scanned lines per column to skip when reading a barcode.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public int Granularity { get; set; } 
@property (nonatomic, assign) NSInteger granularity; 
public int getGranularity() 
public void setGranularity(int value) 
public: 
property int Granularity { 
   int get(); 
   void set (    int ); 
} 
Granularity # get and set (GS1DatabarStackedBarcodeReadOptions) 

Property Value

An Int32 that indicate the number of scanned lines per column to skip when reading a barcode. Must be a value greater to or equal to 1. The default value is 9.

Remarks

A value of 9 means that each tenth line will be scanned when looking for a barcode. Scanning every line will slow the search process while skipping too many lines may skip over the barcode.
