Property Value

Value that indicates the percentage to be used when combining the original image with the noise. Possible values range from 0 through 100. This parameter is used if the PF_Combine or PF_Difference flag is set. A value of 0 indicates that no noise is being used and a value of 100 represents a mix of noise and image.

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); 
 
}
