function Leadtools.Annotations.Core.AnnContainer()

!MISSING Scrap '_RTJavaScript_Class_SYNTAX'!

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
