表示构成用于形成可识别单词的逻辑分组的笔画集合的 ContextNode。

命名空间： System.Windows.Ink
程序集： IAWinFX（在 IAWinFX.dll 中）

语法

声明
Public NotInheritable Class InkWordNode _
    Inherits ContextNode
用法
Dim instance As InkWordNode

public sealed class InkWordNode : ContextNode

public ref class InkWordNode sealed : public ContextNode

public final class InkWordNode extends ContextNode

public final class InkWordNode extends ContextNode

备注

InkWordNode 对象不能包含任何子级。

示例

下面的示例遍历名为 theInkAnalyzer 的 InkAnalyzer 中的所有 InkWordNode 对象，然后绘制显示旋转边界矩形、上行字母线 ascenderLine、下行字母线 descenderLine、中线和基线的线条。这些线条在一个名为 theInkCanvas 的 InkCanvas 上绘制。

' 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);
}
