public ColoredPencilExtendedCommand( 
   int size, 
   int strength,

ColoredPencilExtendedCommand(  
   int size, 
   int strength, 
   int threshold, 
   int pencilRoughness,

__init__(self,size,strength,threshold,pencilRoughness,strokeLength,paperRoughness,angle,flags) # Overloaded constructor

Parameters

size
Size of the neighborhood used to determine the width of the outlines.

strength
Strength factor used to create the "outline". This can be any number that is 0 or greater.

threshold
Threshold value used to determine which pixels are edge pixels (outlines). If the difference determined for a pixel is greater than this value, the pixel is an edge pixel. Valid values range from 0 through 65535 for 64-bit, 48-bit and 16-bit grayscale images and from 0 through 4095 for 12-bit grayscale images. Otherwise, it is from 0 to 255. Use this parameter to control the number of edge pixels found.

pencilRoughness
Percentage of coloring coverage (colored pencil roughness), expressed in tenths of a percent. Valid values are 0 to 1000.

strokeLength
Length of the colored pencil stroke, in pixels.

paperRoughness
Percentage of paper surface roughness, expressed in tenths of a percent. Valid values are 0 to 1000.

angle
Value that represents the direction of the coloring motion, in hundredths of a degree (+/-) This value can be a number from -18000 to 18000. This parameter is ignored when flags = ColoredPencilExtendedCommandFlags.Artistic.

flags
Flags that determine which the type of direction to use and whether to combine the resulted image with the original one or not. For valid values, refer to ColoredPencilExtendedCommandFlags.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
// Run the ColoredPencilExtendedCommand on an image and applies the Colored Pencil Extended filter. 
public void ColoredPencilExtendedConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\NaturalFruits.jpg")); 
 
   // Prepare the command 
   ColoredPencilExtendedCommand command = new ColoredPencilExtendedCommand(5, 4, 0, 250, 15, 100, 0, ColoredPencilExtendedCommandFlags.Artistic); 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Result - ColoredPencilExtendedConstructorCS.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
