Seed Property

Summary

Gets or sets the value that represents the initial seeding value for the pseudo-randomization process. Use 0 for automatic seeding.

Syntax

C++/CLI

Python

public int Seed { get; set; }

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

Seed # get and set (PerlinCommand)

Property Value

Value that represents the initial seeding value for the pseudo-randomization process on which the filter is applied. Use 0 for automatic seeding. If other parameters are kept the same, each seed value always produces the same effect. Each seed value produces an effect different from all of the other seed values. Possible values are 0 or greater.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
public void PerlinCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
   // Prepare the command 
   PerlinCommand command = new PerlinCommand(); 
   RasterColor backColor = new RasterColor(0, 0, 0); 
   RasterColor perlinColor = new RasterColor(255, 0, 0); 
   command.Seed = 0; 
   command.Frequency = 16; 
   command.Iteration = 8; 
   command.Opacity = 75; 
   command.Backcolor = backColor; 
   command.PerlinColor = perlinColor; 
   command.XCircle = image.Width / 2; 
   command.YCircle = image.Height / 2; 
   command.FreqLayout = 50; 
   command.DenLayout = 1; 
   command.PerlinFlags = NoiseLayoutType.PF_Difference | NoiseLayoutType.PF_Circle; 
   command.Run(image); 
 
}

   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images";
