public RemapIntensityCommand( 
   RemapIntensityCommandFlags flags, 
   int[] lookupTable 
)

- (instancetype)initWithFlags:(LTRemapIntensityCommandFlags)flags lookUpTable:(const int *)lookUpTable lookUpTableLength:(NSUInteger)lookUpTableLength NS_DESIGNATED_INITIALIZER;

public RemapIntensityCommand( 
   int flags,  
   int[] lookupTable 
)

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

__init__(self,flags,lookupTable) # Overloaded constructor

Parameters

flags
Determines the color channel that will be used. For more information, refer to RasterColorChannel.

lookupTable
Table of integers containing lookup values.

Example

Run the RemapIntensityCommand on an image.
