CloudsCommand Class

Summary

Applies cloud effects to a bitmap. Imaging Pro and above toolkits include this commant.

Syntax

C++

public class CloudsCommand : RasterCommand

  
Public Class CloudsCommand  
   Inherits RasterCommand

public ref class CloudsCommand : public RasterCommand

Remarks

This method can process the entire image or a region of the image. If the image has a region, the effect is applied only to the region.
The Seed property changes the starting point for the cloud shape randomization process. The same seed value results in clouds of the same shape.
This method supports 12-bit and 16-bit grayscale and 48-bit and 64-bit color images. Only the Document/Medical toolkits support for 12-bit and 16-bit grayscale and 48-bit and 64-bit color images.
This method does not support signed data images.
This command does not support 32-bit grayscale images.

Example

Runs the CloudsCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
public void CloudsCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\Image1.jpg")); 
 
   // Prepare the command 
   CloudsCommand command = new CloudsCommand(); 
   command.Seed = 1000; 
   command.Frequency = 4; 
   command.Density = 10; 
   command.Opacity = 10; 
   command.BackColor = new RasterColor(255, 255, 255); 
   command.CloudsColor = new RasterColor(0, 0, 0); 
   command.Type = CloudsCommandType.Difference; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
