Property Value

Value that indicates the threshold 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. Default value is 0.

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 ColoredPencilExtendedCommandExample() 
{ 
   // 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(); 
   command.Size = 5; 
   command.Strength = 4; 
   command.Threshold = 0; 
   command.PencilRoughness = 250; 
   command.StrokeLength = 15; 
   command.PaperRoughness = 100; 
   command.Flags = ColoredPencilExtendedCommandFlags.Artistic; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Result - ColoredPencilExtendedCommandCS.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images";
