- (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.

C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void RemapIntensityConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   //This example will darken loaded image by using lookup table affected by exponential function. 
   int[] LookupTable = new int[256]; // Array to hold lookup table. 
   //Get Lookup table where the array calculated by the linear function for all the items of the array is from 0 - 255. 
   LookupTable[0] = 255; 
   LookupTable[255] = 0; 
 
   EffectsUtilities.GetFunctionalLookupTable(LookupTable, 0, 255, 5, FunctionalLookupTableFlags.Linear); 
   RemapIntensityCommand command = new RemapIntensityCommand(RemapIntensityCommandFlags.Master, LookupTable); 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
