RadialWaveCommand(  
   int amplitude, 
   int waveLength,

Parameters

amplitude
An integer that represents the magnitude of the wave. Valid values range from 0 to 100.

waveLength
Value that represents the wave length, if the RadialWaveCommand.Period flag is set. Possible values range from 1 - 100 and give the wavelength as a percentage of the image dimensions. If the RadialWaveCommand.Frequency flag is set, this value is the number of repeated waves.

phase
Wave phase shift, in hundredths of degrees. The valid range is from -36000 to 36000 (The value in degrees is nPhase divided by 100).

centerPoint
Point from which the wave radiates.

fillColor
Specifies the fill color for any exposed areas.

flags
Flags that indicate how to handle exposed areas, the type of information in the waveLength parameter.

Example

Run the RadialWaveCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
public void RadialWaveConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   RadialWaveCommand command = new RadialWaveCommand(5, 25, 0, new LeadPoint(image.Width / 2, image.Height / 2), new RasterColor(0, 0, 0), RadialWaveCommandFlags.Repeat | RadialWaveCommandFlags.Frequency); 
   // Apply zoom wave from center of the image. 
   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:\Users\Public\Documents\LEADTOOLS Images"; 
}
