EntryBits Property

Summary

The third value in the "LookupTable Descriptor", which specifies the number of bits for each entry in the LookupTable Data.

Syntax

Objective-C

C++/CLI

Java

Python

public int EntryBits { get; set; }

@property (nonatomic, assign) NSUInteger entryBits;

public int getEntryBits(); 
public void setEntryBits( 
   int intValue 
);

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

EntryBits # get and set (DicomLookupTableDescriptor)

Property Value

The third value in the "LookupTable Descriptor", which specifies the number of bits for each entry in the LookupTable Data.
