Represents a ContextNode for a collection of strokes that make up a logical grouping that forms a recognizable word.

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

Syntax

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

public sealed class InkWordNode : ContextNode

public ref class InkWordNode sealed : public ContextNode

public final class InkWordNode extends ContextNode

Remarks

An InkWordNode object cannot contain any children.

Examples

The following example loops through all InkWordNode objects from an InkAnalyzer, theInkAnalyzer, and then draws lines that show the rotated bounding rectangle, the ascender line, ascenderLine, the descender line, descenderLine, the midline, and the baseline. The lines are drawn on an InkCanvas, theInkCanvas.

' Loop through all of the ink words 
Dim inkWords As ContextNodeCollection = _
    theInkAnalyzer.FindNodesOfType(ContextNodeType.InkWord)
Dim inkWord As InkWordNode

For Each inkWord In inkWords
    ' Show rotated bounding box in blue 
    Dim rotatedBounds As New Polygon()

    rotatedBounds.Points = inkWord.GetRotatedBoundingBox()
    rotatedBounds.Stroke = Brushes.Blue

    Me.theInkCanvas.Children.Add(rotatedBounds)
    ' Show the ascender line in green 
    Dim ascenderLine As New Polyline()

    ascenderLine.Points = inkWord.GetAscender()
    ascenderLine.Stroke = Brushes.Green

    Me.theInkCanvas.Children.Add(ascenderLine)
    ' Show the baseline in purple 
    Dim baseline As New Polyline()

    baseline.Points = inkWord.GetBaseline()
    baseline.Stroke = Brushes.Purple

    theInkCanvas.Children.Add(baseline)
    ' Show the descender line in yellow 
    Dim descenderLine As New Polyline()

    descenderLine.Points = inkWord.GetDescender()
    descenderLine.Stroke = Brushes.Yellow

    theInkCanvas.Children.Add(descenderLine)
    ' Show the descender line in brown 
    Dim midline As New Polyline()

    midline.Points = inkWord.GetMidline()
    midline.Stroke = Brushes.Brown

    theInkCanvas.Children.Add(midline)
Next inkWord

// Loop through all of the ink words
ContextNodeCollection inkWords =
    theInkAnalyzer.FindNodesOfType(ContextNodeType.InkWord);
foreach (InkWordNode inkWord in inkWords)
{
    // Show rotated bounding box in blue
    Polygon rotatedBounds = new Polygon();

    rotatedBounds.Points = inkWord.GetRotatedBoundingBox();
    rotatedBounds.Stroke = Brushes.Blue;

    this.theInkCanvas.Children.Add(rotatedBounds);


    // Show the ascender line in green
    Polyline ascenderLine = new Polyline();

    ascenderLine.Points = inkWord.GetAscender();
    ascenderLine.Stroke = Brushes.Green;

    this.theInkCanvas.Children.Add(ascenderLine);

    // Show the baseline in purple
    Polyline baseline = new Polyline();

    baseline.Points = inkWord.GetBaseline();
    baseline.Stroke = Brushes.Purple;

    theInkCanvas.Children.Add(baseline);

    // Show the descender line in yellow
    Polyline descenderLine = new Polyline();

    descenderLine.Points = inkWord.GetDescender();
    descenderLine.Stroke = Brushes.Yellow;

    theInkCanvas.Children.Add(descenderLine);   

    // Show the midline in brown
    Polyline midline = new Polyline();

    midline.Points = inkWord.GetMidline();
    midline.Stroke = Brushes.Brown;

    theInkCanvas.Children.Add(midline);
}
