PointsArray Property

Summary

Sets or gets an array of LeadPoint arrays that holds the starting point/path for each segment.

Syntax

Objective-C

C++/CLI

Java

Python

public LeadPoint[][] PointsArray { get; set; }

@property (nonatomic, strong) NSArray<NSArray<NSValue *> *> *pointsArray; //LeadPoint

public LeadPoint> getPointsArray(); 
public void setPointsArray( 
   java.util.ArrayList<java.util.ArrayList<LeadPoint>> leadPoint> leadPoint 
);

public: 
property array<array<LeadPoint>^>^ PointsArray { 
   array<array<LeadPoint>^>^ get(); 
   void set (array<array<LeadPoint>^>^ ); 
}

PointsArray # get and set (WatershedCommand)

Property Value

Array that represents the starting point or path for each segment in the image.

Remarks

Each array of LeadPoint structures should hold a point or path that represents the starting point/path for each segment.
If this array has not been set this command will throw an Invalid Parameters exception.

Example

Java

using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void WatershedCommandExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   //Load an image 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE3.dcm")); 
 
   LeadPoint[][] pointsArray = new LeadPoint[4][]; 
 
   for (int idx = 0; idx < 4; idx++) 
      pointsArray[idx] = new LeadPoint[2]; 
 
   // Set starting point and end point for each segment path. 
   pointsArray[0][0] = new LeadPoint(35, 100);

   pointsArray[3][1] = new LeadPoint(350, 330); 
 
   //Prepare the command 
   WatershedCommand command = new WatershedCommand(pointsArray); 
 
   //Apply  
   command.Run(image);
