Summary

Initializes a new DicomLookupTableDescriptor with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public DicomLookupTableDescriptor( 
   int firstStoredPixelValueMapped, 
   int entryBits 
)

- (instancetype)initWithFirstStoredPixelValueMapped:(NSInteger)firstStoredPixelValueMapped entryBits:(NSUInteger)entryBits NS_DESIGNATED_INITIALIZER;

public DicomLookupTableDescriptor( 
   int firstStoredPixelValueMapped, 
   int entryBits 
);

public: 
DicomLookupTableDescriptor(  
   int firstStoredPixelValueMapped, 
   int entryBits 
)

__init__(self,firstStoredPixelValueMapped,entryBits) # Overloaded constructor

Parameters

firstStoredPixelValueMapped
The second value in the "LookupTable Descriptor", which specifies the first input value mapped.

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