語法

'宣告
Public Function FindInkLeafNodes As ContextNodeCollection
'用途
Dim instance As InkAnalyzer
Dim returnValue As ContextNodeCollection

returnValue = instance.FindInkLeafNodes()

public ContextNodeCollection FindInkLeafNodes()

分葉節點不包含子節點。

範例

下列範例會對 InkAnalyzer, theInkAnalyzer. 的所有筆墨分葉節點進行迴圈，並且將最低者設為紅色。

Dim lowest As Integer = Integer.MinValue
Dim lowestNode As ContextNode = Nothing
Dim leafNode As ContextNode
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;
                    lowest = leafNode.Location.GetBounds().Bottom;
                }
                // Set each stroke to black
                foreach (Stroke stroke in leafNode.Strokes)
                {
                    stroke.DrawingAttributes = new DrawingAttributes(Color.Black);
                }
            }
            // Set lowest stroke to red
            if (lowestNode != null)
            {
                foreach (Stroke stroke in lowestNode.Strokes)
                {
                    stroke.DrawingAttributes = new DrawingAttributes(Color.Red);
                }
            }
