Parameters

seed
Value that represents the initial seeding value for the pseudo-randomization process. 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.

frequency
Value that represents the frequency component for both the x and y axis. Possible values range from 0 to 16. No noise is created if the value is 0. Increasing this value increases the noise.

iteration
Value that represents the number of iterations that will be calculated. Possible values range from 0 to 8. No noise is created if the value is 0. Increasing this value increases the detail in the noise, as well as computation time.

opacity
Value that represents the percentage to be used when combining the original image with the noise. Possible values range from 0 through 100. A value of 0 indicates that no noise is being used and a value of 100 represents a mix of noise and image.

backColor
The RasterColor value that represents the background color.

perlinColor
The RasterColor value that represents the Perlin noise color.

xCircle
The x coordinate, in pixels and in image coordinates, for the center point of the concentric circles. Possible values range from 0 to the height of the image. This parameter is only used if the PF_Circle flag is set.

yCircle
The y coordinate, in pixels and in image coordinates, for the center point of the concentric circles. Possible values range from 0 to the height of the image. This parameter is only used if the PF_Circle flag is set.

freqLayout
Value used to control the frequency of the circles or lines to be created for the noise image. Valid values range from 0 to 100. Increase this value to increase the number of circles or lines drawn.

denLayout
Value that represents the density of the layout for the produced noise. Possible values range from 0 through 100. When using a low denLayout value, the noise will appear with light color.

perlinFlags
Flags that indicate how to apply the effect, and which layout pattern to use for the noise.

Example

Run the PerlinCommand on an image and applies the Perlin filter.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
public void PerlinConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
   // Prepare the command 
   RasterColor backColor = new RasterColor(0, 0, 0); 
   RasterColor perlinColor = new RasterColor(0, 255, 0); 
   PerlinCommand command = new PerlinCommand(0, 16, 8, 75, backColor, perlinColor, image.Width / 2, image.Height / 2, 50, 1, NoiseLayoutType.PF_Combine | NoiseLayoutType.PF_Circle); 
 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images"; 
}
