Параметры

strokes
Тип: System.Windows.Ink.StrokeCollection
The strokes that the ink leaf nodes contain.

Возвращаемое значение

Тип: System.Windows.Ink.ContextNodeCollection
The ink leaf nodes that contain the specified strokes.

Заметки

Examples of ink leaf nodes are InkWordNode, InkDrawingNode, and InkBulletNode.

Leaf nodes do not contain child nodes.

An exception is thrown if strokes is nullссылка null (Nothing в Visual Basic). If no nodes contain the strokes, an empty ContextNodeCollection is returned. Similarly, if an empty StrokeCollection collection is passed in, an empty ContextNodeCollection is returned.

Примеры

The following example calls FindInkLeafNodes to find the ink leaf nodes in an InkAnalyzer (named theInkAnalyzer) containing strokes that match those in the StrokeCollection (selectedStrokes). It then changes the color of the matching strokes to red.

For Each node As ContextNode In theInkAnalyzer.FindInkLeafNodes(selectedStrokes)
    For Each Stroke As Stroke In node.Strokes
        Stroke.DrawingAttributes.Color = Colors.Red
    Next Stroke
Next node

foreach (ContextNode node in theInkAnalyzer.FindInkLeafNodes(selectedStrokes))
{
    foreach (Stroke stroke in node.Strokes)
    {
        stroke.DrawingAttributes.Color = Colors.Red;
    }
}
