Scale Property

Summary

Factor used to increase or decrease the various amplitude values in the Amplitudes property.

Syntax

C++/CLI

Python

public int Scale { get; set; }

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

Scale # get and set (FreeHandShearCommand)

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. The valid range is from 0 to 100.

using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
using Leadtools.ImageProcessing.Effects;

   // Prepare the command

      } 
   }

   command.Scale = 100; 
   command.FillColor = new RasterColor(0, 0, 0);

   // Apply the shear wave horizontally. 
   command.Run(image);
