LowBit Property

Summary

Gets or sets a value indicating the low bit used for leveling.

Syntax

Objective-C

C++/CLI

Java

Python

public int LowBit { get; set; }

@property (nonatomic, assign) NSInteger lowBit;

public int getLowBit(); 
public void setLowBit( 
   int intValue 
);

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

LowBit # get and set (WindowLevelExtCommand)

Property Value

Value indicating the low bit used for leveling. 0 <= LowBit <= HighBit <= (11 for 12-bit grayscale or 15 for 16-bit grayscale).
