ContextNode.Location Property
Gets the position and size of the ContextNode object.
Namespace: Microsoft.Ink
Assembly: Microsoft.Ink.Analysis (in Microsoft.Ink.Analysis.dll)
Syntax
'Declaration
Public ReadOnly Property Location As AnalysisRegion
'Usage
Dim instance As ContextNode
Dim value As AnalysisRegion
value = instance.Location
public AnalysisRegion Location { get; }
public:
property AnalysisRegion^ Location {
AnalysisRegion^ get ();
}
public function get Location () : AnalysisRegion
Property Value
Type: Microsoft.Ink.AnalysisRegion
The position and size of the ContextNode object.
Remarks
The location for a given ContextNode is determined by the union of the location of all strokes. If the ContextNode is a leaf node, strokes associated with that node are used. If the ContextNode is not a leaf node, all descendant leaf ContextNode objects are used to determine the location of the ContextNode.
If the ContextNode is not an ink leaf node or does not have any descendant ink leaf nodes, the node is considered to be a non-ink node or an ancestor of one or more non-ink nodes. The location of this type of node is determined by the location value of the non-ink leaf nodes.
Examples
This example draws a blue box around a ContextNode, cNode, whose strokes have been drawn on a Panel, theNotePanel.
