Represents a ContextNode for a line of words.

Namespace: System.Windows.Ink
Assembly: IAWinFX (in IAWinFX.dll)

Syntax

'Declaration
Public NotInheritable Class LineNode _
    Inherits ContextNode
'Usage
Dim instance As LineNode

public sealed class LineNode : ContextNode

public ref class LineNode sealed : public ContextNode

public final class LineNode extends ContextNode

Remarks

A LineNode object can contain the following types of children:

Any number of InkWordNode objects.
Any number of TextWordNode objects.

Examples

The following example loops through all LineNode objects from an InkAnalyzer, theInkAnalyzer, and uses a Polygon to draw the rotated bounding rectangle. The lines are drawn on an InkCanvas, theInkCanvas.

' Loop through all of the lines 
Dim lines As ContextNodeCollection = _
    theInkAnalyzer.FindNodesOfType(ContextNodeType.Line)
Dim line As LineNode

For Each line In lines
    ' Convert corners to pixel coordinates 
    Dim lineBounds As New Polygon()

    lineBounds.Points = line.GetRotatedBoundingBox()
    lineBounds.Stroke = Brushes.Blue

    theInkCanvas.Children.Add(lineBounds)
Next line

// Loop through all of the lines
ContextNodeCollection lines =
    theInkAnalyzer.FindNodesOfType(ContextNodeType.Line);
foreach (LineNode line in lines)
{
    // Show rotated bounding box in blue
    Polygon lineBounds = new Polygon();

    lineBounds.Points = line.GetRotatedBoundingBox();
    lineBounds.Stroke = Brushes.Blue;

    theInkCanvas.Children.Add(lineBounds);
}
