WaveLength Property

Summary

Gets or sets a value that represents the wave length.

Syntax

C++/CLI

Python

public int WaveLength { get; set; }

public: 
property int WaveLength { 
   int get(); 
   void set (    int ); 
}

WaveLength # get and set (FreeHandWaveCommand)

Property Value

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

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void FreeHandWaveCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   LeadPoint[] UserPoint = new LeadPoint[4]; 
   int[] Amplitudes = new int[13]; 
 
   FreeHandWaveCommand command = new FreeHandWaveCommand(); 
 
   // Fill UserPoint array with points that define a triangular wave 
   UserPoint[0].X = 0; 
   UserPoint[0].Y = 0; 
   UserPoint[1].X = 3; 
   UserPoint[1].Y = 10; 
   UserPoint[2].X = 9; 
   UserPoint[2].Y = -10; 
   UserPoint[3].X = 12; 
   UserPoint[3].Y = 0; 
 
   //Draw a triangular wave according to UserPoint points and store the Amplitudes values in the Amplitudes array. 
   EffectsUtilities.GetCurvePoints(Amplitudes, UserPoint, CurvePointsType.Linear); 
 
   command.Amplitudes = Amplitudes; 
   command.Scale = 100; 
   command.WaveLength = 10; 
   command.Angle = 0; 
   command.FillColor = new RasterColor(0, 0, 0); 
   command.Flags = FreeHandWaveCommandFlags.Repeat | FreeHandWaveCommandFlags.Frequency; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
