InkAnalyzer.FindInkLeafNodes Method (StrokeCollection)
Returns a ContextNodeCollection containing ink leaf nodes that contain certain specified strokes.
Namespace: System.Windows.Ink
Assembly: IAWinFX (in IAWinFX.dll)
Syntax
'Declaration
Public Function FindInkLeafNodes ( _
strokes As StrokeCollection _
) As ContextNodeCollection
'Usage
Dim instance As InkAnalyzer
Dim strokes As StrokeCollection
Dim returnValue As ContextNodeCollection
returnValue = instance.FindInkLeafNodes(strokes)
public ContextNodeCollection FindInkLeafNodes(
StrokeCollection strokes
)
public:
ContextNodeCollection^ FindInkLeafNodes(
StrokeCollection^ strokes
)
public function FindInkLeafNodes(
strokes : StrokeCollection
) : ContextNodeCollection
Parameters
strokes
Type: System.Windows.Ink.StrokeCollectionThe strokes that the ink leaf nodes contain.
Return Value
Type: System.Windows.Ink.ContextNodeCollection
The ink leaf nodes that contain the specified strokes.
Remarks
Examples of ink leaf nodes are InkWordNode, InkDrawingNode, and InkBulletNode.
Leaf nodes do not contain child nodes.
An exception is thrown if strokes is nulla null reference (Nothing in 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.
Examples
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;
}
}
