Examples

The following example shows how to loop through all the LineNode objects in an InkAnalyzer named theInkAnalyzer. In each line, it loops through all InkWordNode objects and, if two inkWord nodes are recognized as the same word, it marks them as 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
// 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.
ContextNodeCollection lines =
    theInkAnalyzer.FindNodesOfType(ContextNodeType.Line);
foreach (ContextNode lineNode in lines)
{
    InkWordNode previousWord = null;
    foreach (InkWordNode inkWord in
             theInkAnalyzer.FindNodesOfType(ContextNodeType.InkWord, lineNode))
    {
        if (previousWord != null &&
            previousWord.GetRecognizedString() == inkWord.GetRecognizedString())
        {
            foreach (Stroke stroke in previousWord.Strokes)
                stroke.DrawingAttributes.Color = Colors.Red;
            foreach (Stroke stroke in inkWord.Strokes)
                stroke.DrawingAttributes.Color = Colors.Red;
        }
        previousWord = inkWord;
    }
