Adds a stroke to a custom recognizer node.

Namespace: System.Windows.Ink
Assembly: IAWinFX (in IAWinFX.dll)

Syntax

'Declaration
Public Function AddStrokeToCustomRecognizer ( _
    stroke As Stroke, _
    customRecognizer As CustomRecognizerNode _
) As ContextNode
'Usage
Dim instance As InkAnalyzer 
Dim stroke As Stroke 
Dim customRecognizer As CustomRecognizerNode 
Dim returnValue As ContextNode 

returnValue = instance.AddStrokeToCustomRecognizer(stroke, _
    customRecognizer)

public ContextNode AddStrokeToCustomRecognizer(
    Stroke stroke,
    CustomRecognizerNode customRecognizer
)

public:
ContextNode^ AddStrokeToCustomRecognizer(
    Stroke^ stroke, 
    CustomRecognizerNode^ customRecognizer
)

public function AddStrokeToCustomRecognizer(
    stroke : Stroke, 
    customRecognizer : CustomRecognizerNode
) : ContextNode

Parameters

stroke
Type: System.Windows.Ink.Stroke

The stroke added to the custom recognizer node.

customRecognizer
Type: System.Windows.Ink.CustomRecognizerNode

The custom recognizer node.

Return Value

Type: System.Windows.Ink.ContextNode
The context node to which the InkAnalyzer added the stroke.

Remarks

The InkAnalyzer adds the Stroke to an UnclassifiedInkNode in the SubNodes collection of customRecognizer. If no such UnclassifiedInkNode exists, the InkAnalyzer creates a new UnclassifiedInkNode under customRecognizer and adds the stroke to the new UnclassifiedInkNode.

This method expands the DirtyRegion to the union of the region's current value and the bounding box of the added stroke.

If the stroke is already attached to the InkAnalyzer, the InkAnalyzer throws an exception.

If customRecognizer is not a CustomRecognizerNode, the InkAnalyzer throws an exception.

Examples

This example shows an excerpt from an event handler for the StrokeCollected event of an InkCanvas. The stroke is added to the CustomRecognizerNode, named theCustomRecognizerNode.

' Add the stroke to the specified CustomRecognizerNode. 
Me.theInkAnalyzer.AddStrokeToCustomRecognizer(e.Stroke, theCustomRecognizerNode)

// Add the stroke to the specified CustomRecognizerNode. 
this.theInkAnalyzer.AddStrokeToCustomRecognizer(
    e.Stroke, theCustomRecognizerNode);
