Namespace: Microsoft.Ink
Assembly: Microsoft.Ink.Analysis (in Microsoft.Ink.Analysis.dll)

Syntax

'Declaration
Public Function FindInkLeafNodes As ContextNodeCollection
'Usage
Dim instance As InkAnalyzer
Dim returnValue As ContextNodeCollection

returnValue = instance.FindInkLeafNodes()

public ContextNodeCollection FindInkLeafNodes()

public:
ContextNodeCollection^ FindInkLeafNodes()

public ContextNodeCollection FindInkLeafNodes()

Rückgabewert

Typ: Microsoft.Ink.ContextNodeCollection
Alle Freihandendknoten, bei denen es sich um ContextNode-Objekte handelt, die Freihandstriche enthalten.

Hinweise

Beispiele für Freihandendknoten sind InkWordNode, InkDrawingNode und InkBulletNode.

Endknoten enthalten keine untergeordneten Knoten.

Beispiele

Im folgenden Beispiel werden alle Freihandendknoten von InkAnalyzer, theInkAnalyzer, durchlaufen. Der Knoten auf unterster Ebene wird rot hervorgehoben.

Dim lowest As Integer = Integer.MinValue
Dim lowestNode As ContextNode = Nothing

For Each leafNode In theInkAnalyzer.FindInkLeafNodes()
    ' Find lowest node
    If leafNode.Location.GetBounds().Bottom > lowest Then
        lowestNode = leafNode
        lowest = leafNode.Location.GetBounds().Bottom
    End If
    ' Set each stroke to black
    Dim inkStroke As Stroke
    For Each inkStroke In leafNode.Strokes
        inkStroke.DrawingAttributes = New DrawingAttributes(Color.Black)
    Next inkStroke
Next leafNode
' Set lowest stroke to red
If Not (lowestNode Is Nothing) Then
    Dim inkStroke As Stroke
    For Each inkStroke In lowestNode.Strokes
        inkStroke.DrawingAttributes = New DrawingAttributes(Color.Red)
    Next inkStroke
End If

            int lowest = int.MinValue;
            ContextNode lowestNode = null;
            foreach (ContextNode leafNode in theInkAnalyzer.FindInkLeafNodes())
            {
                // Find lowest node
                if (leafNode.Location.GetBounds().Bottom > lowest)
                {
                    lowestNode = leafNode;
