Syntax

C++/CLI

Python

public int DeltaDirection { get; set; }

public: 
property int DeltaDirection { 
   int get(); 
   void set (    int ); 
}

DeltaDirection # get and set (ContourFilterCommand)

Property Value

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

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void ContourFilterCommandExample() 
{ 
   // 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(); 
   command.Threshold = 15; 
   command.DeltaDirection = 35; 
   command.MaximumError = 5; 
   command.Type = ContourFilterCommandType.Thin; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
