@property (nonatomic, assign) LTBarCodeReadPreprocessOptions options;

public int getOptions(); 
public void setOptions( 
   int intValue 
);

public: 
property BarCodeReadPreprocessOptions Options { 
   BarCodeReadPreprocessOptions get(); 
   void set (    BarCodeReadPreprocessOptions ); 
}

Property Value

BarCodeReadPreprocessOptions object that represents the binarization method used to convert the image to black and white.

Remarks

Using the default flag detects the best binarization methods to use for the detected barcode.
