FunctionalLightCommand Class

Summary
Adds light to the image according to a function-based distribution. This light will be generated by one of the following methods: linear, quadratic, sine, cosine, or using freehand points. This method is available in the Imaging Pro and above toolkits.
Syntax
C#
VB
C++
public class FunctionalLightCommand : RasterCommand 
  
Public Class FunctionalLightCommand  
   Inherits RasterCommand 
public ref class FunctionalLightCommand : public RasterCommand 
Remarks
  • Controls the brightness of the image according to the method selected for generating the light.
  • This command supports all bits/pixel supported by LEADTOOLS.
  • This command supports 12-bit and 16-bit grayscale and 48-bit and 64-bit color images. Support for 12-bit and 16-bit grayscale and 48-bit and 64-bit color images is available only in the Document/Medical toolkits.
  • This command does not support signed data images.
  • This command does not support 32-bit grayscale images.
Example

Run the FunctionalLightCommand on an image.

C#
VB
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
using Leadtools.ImageProcessing.Effects; 
 
public void FunctionalLightCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
   // Prepare the command 
   FunctionalLightCommand command = new FunctionalLightCommand(); 
   command.RedAmplitude = 75; 
   command.Flags = FunctionalLightCommandFlags.LinearQuadratic | 
      FunctionalLightCommandFlags.LinearOuter; 
   command.Origin = new LeadPoint((image.Width / 2), (image.Height / 2)); 
   // Apply the linear lighting effect. 
   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:\LEADTOOLS21\Resources\Images"; 
}

   command.Origin = New LeadPoint(leadImage.Width \ 2, leadImage.Height \ 2) 
   ' Apply the linear lighting effect. 
   command.Run(leadImage) 
   codecs.Save(leadImage, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24)
