ContourFilterCommand Constructor(int,int,int,ContourFilterCommandType)

Summary
Initializes a new ContourFilterCommand class object with explicit parameters.
Syntax
C#
C++/CLI
Python
public: 
ContourFilterCommand(  
   int threshold, 
   int deltaDirection, 
   int maximumError, 
   ContourFilterCommandType type 
) 
__init__(self,threshold,deltaDirection,maximumError,type) # Overloaded constructor 

Parameters

threshold
Threshold of the gradient magnitude. Values below this will be considered as background, and will be set to 0. Values can be from 1 to 254. A lower threshold provides a better quality image. Default is 15.

deltaDirection
Maximum angle for the thinning algorithm. Values can be from 1 to 64. Default is 35.

maximumError
Maximum error for approximation algorithm. Values can be from 0 to 255. Default is 5. This parameter is only valid if the type parameter is set to ApproxColor.

type
Flag that controls the resulting image. This value tells the command what process to complete before returning.

Example

Run the ContourFilterCommand on an image with LinkColor Option.

C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void ContourFilterConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Beauty16.jpg"), 16, CodecsLoadByteOrder.BgrOrGray, 1, 1); 
 
   // Prepare the command 
   ContourFilterCommand command = new ContourFilterCommand(15, 35, 5, ContourFilterCommandType.LinkColor); 
   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"; 
}
