Points Property

Summary
Gets the collection of Leadtools.LeadPointD objects that define this AnnObject.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public LeadPointCollection Points { get; } 
@property (nonatomic, strong, readonly) LTLeadPointCollection *points; 
public LeadPointCollection getPoints() 
public:  
   property LeadPointCollection^ Points 
   { 
      LeadPointCollection^ get() 
   } 
Points # get  (AnnObject) 

Property Value

The Leadtools.LeadPointD objects that define this AnnObject. The default value is an empty collection that is ready to use.

Remarks

Each AnnObject contains an array of Leadtools.LeadPointD in container coordinates that define its location and size. How these points are interpreted in forming the object shape is up to the derived class. For instance a line object would normally have two points: start and end. A rectangle object will have four points for the each corner (to keep track of rotated objects) and so forth.

Example
C#
using Leadtools.Annotations.Automation; 
using Leadtools.Annotations.Engine; 
using Leadtools.Codecs; 
using Leadtools.Annotations.WinForms; 
 
public void AnnContainer_AnnContainer()

   // Create a new annotation container, 8.5 by 11 inches 
   AnnContainer container = new AnnContainer(); 
   // Size must be in annotation units (1/720 of an inch) 
   container.Size = LeadSizeD.Create(8.5 * inch, 11 * inch); 
   //Change Offset position 
   container.Offset = new LeadPointD(10, 10); 
 
   // Add a red line object, from 1in 1in to 2in 2in 
   AnnPolylineObject lineObj = new AnnPolylineObject();

   container.Children.Add(lineObj); 
 
   // Add a blue on yellow rectangle from 3in 3in to 4in 4in 
   AnnRectangleObject rectObj = new AnnRectangleObject(); 
   rectObj.Rect = LeadRectD.Create(3 * inch, 3 * inch, 1 * inch, 1 * inch);
