Public Function New( _ 
   ByVal flags As RemapIntensityCommandFlags, _ 
   ByVal lookupTable() As Integer _ 
) 
- (instancetype)initWithFlags:(LTRemapIntensityCommandFlags)flags 
                  lookUpTable:(const int *)lookUpTable

public RemapIntensityCommand( 
   int flags,  
   int[] lookupTable 
) 
public: 
RemapIntensityCommand(  
   RemapIntensityCommandFlags flags, 
   array<int>^ lookupTable
