SphereCommand Class

Summary

Warps the image around a 3D spherical shape. This command is available in the Imaging Pro and above toolkits.

Syntax

C++

public class SphereCommand : RasterCommand

  
Public Class SphereCommand  
   Inherits RasterCommand

public ref class SphereCommand : public RasterCommand

Remarks

This command will warp the image as a 3D spherical shape 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 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 SphereCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
public void SphereCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   SphereCommand command = new SphereCommand(); 
   // Warp the image around 3D spherical shape around the center of the image. 
   command.CenterPoint = new LeadPoint((image.Width / 2), (image.Height / 2)); 
   command.Value = 10; 
   command.FillColor = new RasterColor(0, 0, 0); 
   command.Flags = SphereCommandFlags.Repeat | 
      SphereCommandFlags.Rotate; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
