Angle Property

Summary

Gets or sets a value that specifies the edge detector direction, in hundredths of degrees.

Syntax

Objective-C

C++/CLI

Java

Python

public int Angle { get; set; }

@property (nonatomic, assign) NSInteger angle;

public int getAngle(); 
public void setAngle( 
   int intValue 
);

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

Angle # get and set (DirectionEdgeStatisticalCommand)

Property Value

Value that specifies the edge detector direction, in hundredths of degrees. Valid values range from -18000 through 18000. Positive values are produced by counterclockwise rotation above the horizon and negative values are produced by clockwise rotation below the horizon. This value is divided internally by 100.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void DirectionEdgeStatisticalCommandExample() 
{ 
   // Load an image

   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\\NaturalFruits.jpg")); 
 
   // Prepare the command 
   DirectionEdgeStatisticalCommand command = new DirectionEdgeStatisticalCommand(); 
 
   command.Dimension = 15; 
   command.Threshold = 128; 
   command.Angle = 4500; 
   command.EdgeColor = new RasterColor(255, 255, 255);

   //Find the edges in the image. 
   command.Run(image);
