ContextNodeCollection Class

Contains a collection of ContextNode objects that are the result of an ink analysis.

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

'Declaration
Public Class ContextNodeCollection _
	Implements ICollection, IEnumerable
'Usage
Dim instance As ContextNodeCollection

The following example shows how to loop through a ContextNodeCollection from the InkAnalyzer. FindNodesOfType(ContextNodeType, ContextNode) method of an InkAnalyzer named theInkAnalyzer. The example loops through a collection of LineNode objects and, if two consecutive InkWordNode objects are the same word, it makes their strokes red.

' If two identical ink words occur next to each other, mark them as red. 
' Note: This doesn't actually look for pairs that go across two lines. 
Dim lines As ContextNodeCollection = theInkAnalyzer.FindNodesOfType(ContextNodeType.Line)
Dim lineNode As ContextNode
For Each lineNode In  lines
    Dim previousWord As InkWordNode = Nothing 

    For Each inkWord As InkWordNode In _
        theInkAnalyzer.FindNodesOfType(ContextNodeType.InkWord, lineNode)

        If Not (previousWord Is Nothing) AndAlso _
            previousWord.GetRecognizedString() = inkWord.GetRecognizedString() Then 

            For Each stroke As Stroke In previousWord.Strokes
                stroke.DrawingAttributes.Color = Colors.Red
            Next stroke

            For Each stroke As Stroke In inkWord.Strokes
                stroke.DrawingAttributes.Color = Colors.Red
            Next stroke
        End If

        previousWord = inkWord
    Next inkWord
Next lineNode
