Remarks

The annotation container is a rectangular area that holds related annotation objects (AnnObject). In typical applications, the container holds the annotation objects for a page in a document. The size of the container is the same of the page but in annotation units (1/720 of an inch).

AnnContainer contains the following members:

Member Description

Size, Offset and PageNumber

Properties of the container: Size is the size of the container in annotation units (1/720 of an inch). Offset is an optional offset value (if the container does not start at 0,0) and PageNumber is the optional 1-based page number of the container

Mapper

The object responsible for converting display, container and image coordinates

Children

A collection of AnnObject's. These are the annotation objects that belong in this container. These objects will be rendered when the container is rendered and edited when the container is automated

SelectionObject

Special annotation object that is responsible for maintaining a list of the objects that are currently selected in the container

HitTestPoint and HitTestRect

Helper method to perform hit-testing on the container and return any object under a test point or rectangle

IsVisible, Stroke and Fill

Optional values used when rendering this container: Whether it is visible and the border stroke and interior filling options

Labels

Optional labels that can be used to overlay fixed text on top of the container, such as map legends

Resources

Additional resources such as images that belong to the container

Example
example: function SiteLibrary_DefaultPage$example() {
   var inch = 720.0;

   // Create a new annotation container, 8.5 by 11 inches
   var container = new Leadtools.Annotations.Core.AnnContainer();
   // Size must be in annotation units (1/720 of an inch)
   container.set_size(Leadtools.LeadSizeD.create(8.5 * inch, 11 * inch));

   // Add a red line object, from 1in 1in to 2in 2in
   var lineObj = new Leadtools.Annotations.Core.AnnPolylineObject();
   lineObj.get_points().add(Leadtools.LeadPointD.create(1 * inch, 1 * inch));
   lineObj.get_points().add(Leadtools.LeadPointD.create(2 * inch, 2 * inch));
   lineObj.set_stroke(Leadtools.Annotations.Core.AnnStroke.create(Leadtools.Annotations.Core.AnnSolidColorBrush.create("red"), Leadtools.LeadLengthD.create(1)));
   container.get_children().add(lineObj);

   // Add a blue on yellow rectangle from 3in 3in to 4in 4in
   var rectObj = new Leadtools.Annotations.Core.AnnRectangleObject();
   rectObj.set_rect(Leadtools.LeadRectD.create(3 * inch, 3 * inch, 1 * inch, 1 * inch));
   rectObj.set_stroke(Leadtools.Annotations.Core.AnnStroke.create(Leadtools.Annotations.Core.AnnSolidColorBrush.create("blue"), Leadtools.LeadLengthD.create(1)));
   rectObj.set_fill(Leadtools.Annotations.Core.AnnSolidColorBrush.create("yellow"));
   container.get_children().add(rectObj);

   // Show the container
   this.showContainer("Before save", container);

   // Create the codecs object to save and load annotations
   var codecs = new Leadtools.Annotations.Core.AnnCodecs();

   // Save the container
   var xmlData = codecs.save(container, Leadtools.Annotations.Core.AnnFormat.annotations, null, 1);

   // delete the container
   container = null;

   // Show information about the data we just saved
   var info = codecs.getInfo(xmlData);
   var message;
   if (info.get_format() == Leadtools.Annotations.Core.AnnFormat.annotations) {
      message = "Version: ";
      message += info.get_version();
      message += " No. of pages: ";
      message += info.get_pages().length;
      message += " page nos: ";
      for (var i = 0; i < info.get_pages().length; i++) {
         message += info.get_pages()[i] + " ";
      }
   }
   else {
      message = "Invalid annotations data";
   }

   alert(message);

   // Load the container we just saved
   container = codecs.load(xmlData, 1);

   // Show it
   this.showContainer("After load", container);
},

showContainer: function SiteLibrary_DefaultPage$showContainer(message, container) {
   var str = message + "\nContainer size: ";

   // Add the size
   var inch = 720;
   var width = container.get_size().get_width() / inch;
   var height = container.get_size().get_height() / inch;
   str += width + " by " + height + " inches" + "\n";

   // Add the objects
   str += "Contains " + container.get_children().get_count() + " objects(s)\n";
   for (var i = 0; i < container.get_children().get_count(); i++) {
      var annObj = container.get_children().get_item(i);

      str += "Object: " + annObj.get_friendlyName() + " at ";
      for (var j = 0; j < annObj.get_points().get_count(); j++) {
         var pt = annObj.get_points().get_item(j);
         var x = pt.get_x() / inch;
         var y = pt.get_y() / inch;
         str += "(" + x + ", " + y + ") ";
      }

      str += "\n";
   }

   alert(str);
},
