Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void RemapIntensityCommandExample() 
{ 
   // 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(); 
   command.Flags = RemapIntensityCommandFlags.Master; 
   command.LookupTable = 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";
