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;
}
}
