Scale Property

Summary

Gets or sets a value used to increase or decrease the various amplitude values in the Amplitudes array.

Syntax

C++/CLI

Python

public int Scale { get; set; }

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

Scale # get and set (FreeHandWaveCommand)

Property Value

Factor used to increase or decrease the various amplitude values in the Amplitudes array. Each value in the Amplitudes array is multiplied by this factor. The real factor value is the Scale value divided by 100. This property only accepts positive values.

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); 
 
}
