Gets the position and size of the ContextNodeBase object.

Namespace: System.Windows.Ink.AnalysisCore
Assembly: IACore (in iacore.dll)

Syntax

'Declaration
Public ReadOnly Property Location As AnalysisRegionBase
'Usage
Dim instance As ContextNodeBase
Dim value As AnalysisRegionBase

value = instance.Location

public AnalysisRegionBase Location { get; }

public:
property AnalysisRegionBase^ Location {
    AnalysisRegionBase^ get ();
}

/** @property */
public AnalysisRegionBase get_Location ()

public function get Location () : AnalysisRegionBase

Not applicable.

Property Value

The position and size of the ContextNodeBase object.

Remarks

The location for a container node is determined by unioning all the leaf's locations. The location for an ink leaf nodes is determined by unioning the strokes locations. The location for a non-ink leaf node is determined by whatever the user originally set on those nodes.

Example

This example draws a blue box around a ContextNodeBase, currentNode, whose strokes were drawn on a Panel, theNotePanel.

' Convert bounds to pixels
Dim panelGraphics As Graphics = Me.theNotesPanel.CreateGraphics()
Dim nodeBounds() As Integer = currentNode.Location.GetBounds()
Dim upperLeft As New Point(nodeBounds(0), nodeBounds(1))
Dim lowerRight As New Point(nodeBounds(2), nodeBounds(3))
Me.theInkCollector.Renderer.InkSpaceToPixel(panelGraphics, upperLeft)
Me.theInkCollector.Renderer.InkSpaceToPixel(panelGraphics, lowerRight)

' Draw rectangle
panelGraphics.DrawRectangle(New Pen(Color.Blue), upperLeft.X, upperLeft.Y, lowerRight.X - upperLeft.X, lowerRight.Y - upperLeft.Y)
panelGraphics.Dispose()

// Convert bounds to pixels
Graphics panelGraphics = this.theNotesPanel.CreateGraphics();
int[] nodeBounds = currentNode.Location.GetBounds();
Point upperLeft = new Point(nodeBounds[0], nodeBounds[1]);
Point lowerRight = new Point(nodeBounds[2], nodeBounds[3]);
this.theInkCollector.Renderer.InkSpaceToPixel(panelGraphics, ref upperLeft);
this.theInkCollector.Renderer.InkSpaceToPixel(panelGraphics, ref lowerRight);

// Draw rectangle
panelGraphics.DrawRectangle(new Pen(Color.Blue),
    upperLeft.X, upperLeft.Y, lowerRight.X - upperLeft.X,
    lowerRight.Y - upperLeft.Y);
panelGraphics.Dispose();
