HighBit Property

Summary

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

Syntax

Objective-C

C++/CLI

Java

Python

public int HighBit { get; set; }

@property (nonatomic, assign) NSInteger highBit;

public int getHighBit(); 
public void setHighBit( 
   int intValue 
);

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

HighBit # get and set (WindowLevelCommand)

Property Value

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