CreateBoundary Method

Description

Creates an Item from the boundary of the current open Item.

Syntax

Public Function CreateBoundary() As Integer

Remarks

The boundary of an Item is always 1 dimension less than the Item itself.

For example:

• The boundary of a Polygon item (which is 2-dimensional) is a LineString item.
• The boundary of a LineString item (which is 1-dimensional) is two Point Items (the start and end point of the LineString).
• The boundary of a Point item (which is 0-dimensional) is nothing.

If a Group is open, then graphics are added to the Group, otherwise a new Item is created.
