public int MinimumTextSize { get; set; } 
@property(nonatomic, assign) NSUInteger minimumTextSize; 
public:  
   property Int32 MinimumTextSize 
   { 
      Int32 get() 
      void set(Int32 value) 
   } 
MinimumTextSize # get and set (BlankPageDetectorCommand) 

Property Value

The minimum text height in pixels. All objects with height less than this value will be considered noise.
