public void setPointsArray( 
   java.util.ArrayList<java.util.ArrayList<LeadPoint>> leadPoint> leadPoint 
); 
public: 
property array<array<LeadPoint>^>^ PointsArray {

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
C#
using Leadtools; 
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[0][1] = new LeadPoint(35, 200); 
 
   pointsArray[1][0] = new LeadPoint(180, 115); 
   pointsArray[1][1] = new LeadPoint(300, 115); 
 
   pointsArray[2][0] = new LeadPoint(235, 220); 
   pointsArray[2][1] = new LeadPoint(260, 220); 
 
   pointsArray[3][0] = new LeadPoint(180, 330); 
   pointsArray[3][1] = new LeadPoint(350, 330); 
 
   //Prepare the command 
   WatershedCommand command = new WatershedCommand(pointsArray); 
 
   //Apply  
   command.Run(image); 
}

{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images";
