class DryCommand(RasterCommand):

Remarks

This command simulates what would happen if the image had just been painted with paints and the paints were allowed to dry. The colors become darker, with less brightness.
The effect can be controlled by specifying the size of the neighborhood that is used for calculating each pixel value.
If the image has a region, the effect will be applied on the region only.
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.

Run the DryCommand on an image with a neighborhood Dimensions = 5x5 pixels.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
public void DryCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Image2.jpg")); 
 
   // Prepare the command 
   DryCommand command = new DryCommand(); 
   command.Dimension = 5; 
   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:\LEADTOOLS23\Resources\Images";
