SwirlCommand Class

Summary

Spins the image according to the rotation angle to produce a swirl pattern. This command is available in the Imaging and above toolkits.

Syntax

C++/CLI

Python

public class SwirlCommand : RasterCommand

public ref class SwirlCommand : public RasterCommand

class SwirlCommand(RasterCommand):

Remarks

The command swirls the image around a specific center point. The center point must be defined inside the image, or inside the region, if the image has a region.
If the image has a region, the effect will be applied on the region only.
This method 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 SwirlCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
public void SwirlCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   SwirlCommand command = new SwirlCommand(); 
   command.CenterPoint = new LeadPoint((image.Width / 2), (image.Height / 2)); 
   command.Angle = 50; 
   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";
