points: LeadPointCollection; // read-only
Each AnnObject contains an array of 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.
For an example, refer to AnnContainer.
