ZoomWaveCommand Class

Summary

Distorts the image with a wave zoomed from the specified center. This command is available in the Imaging and above toolkits.

Syntax

C++/CLI

Python

public class ZoomWaveCommand : RasterCommand

public ref class ZoomWaveCommand : public RasterCommand

class ZoomWaveCommand(RasterCommand):

Remarks

The command applies a sinusoidal wave zoomed from the specified center. 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.

Example

Run the ZoomWaveCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
public void ZoomWaveCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   ZoomWaveCommand command = new ZoomWaveCommand(); 
   command.Amplitude = 20; 
   // Apply zoom wave from center of the image. 
   command.CenterPoint = new LeadPoint(image.Width / 2, image.Height / 2); 
   command.FillColor = new RasterColor(0, 0, 0); 
   command.Frequency = 10; 
   command.Phase = 0; 
   command.ZoomFactor = 0; 
   command.Type = ZoomWaveCommandType.Repeat; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);
