CloudsCommand Class

Summary

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

Syntax

C#
VB
WinRT C#
C++
public class CloudsCommand : RasterCommand 
function Leadtools.ImageProcessing.SpecialEffects.CloudsCommand() 

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.

C#
VB
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); 
 
}
