ContextNodeBaseCollection Class
Visual Studio 2008
Contains a collection of ContextNodeBase objects that are the result of an ink analysis.
Assembly: IACore (in IACore.dll)
The following example shows how to loop through a ContextNodeBaseCollection from the InkAnalyzerBase. FindNodesOfType method of an InkAnalyzerBase named theInkAnalyzerBase. The example loops through all of the line nodes and, if two ink word nodes exist with 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 ContextNodeBaseCollection = _ theInkAnalyzerBase.FindNodesOfType(System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.Line) For Each lineNode As ContextNodeBase In lines Dim previousWord As ContextNodeBase = Nothing Dim previousWordRecognizedString As String = "" For Each inkWord As ContextNodeBase In _ theInkAnalyzerBase.FindNodesOfType(ContextNodeTypeBase.InkWord, lineNode) Dim inkWordRecognizedString As String = "" If inkWord.ContainsPropertyData(PropertyGuidsForContextNodesBase.RecognizedString) Then inkWordRecognizedString = _ CType(inkWord.GetPropertyData(PropertyGuidsForContextNodesBase.RecognizedString), String) End If ' TODO: I think I can get rid of this and just assign the previous string ' to the current string If Not previousWord Is Nothing Then previousWordRecognizedString = _ CType(previousWord.GetPropertyData(PropertyGuidsForContextNodesBase.RecognizedString), String) End If If previousWordRecognizedString <> "" Then Dim previousWordStrokes As Strokes = theInk.CreateStrokes(previousWord.GetStrokeIds()) Dim inkWordStrokes As Strokes = theInk.CreateStrokes(previousWord.GetStrokeIds()) For Each aStroke As Stroke In previousWordStrokes aStroke.DrawingAttributes = New DrawingAttributes(Color.Red) Next aStroke For Each aStroke As Stroke In inkWordStrokes aStroke.DrawingAttributes = New DrawingAttributes(Color.Red) Next aStroke End If previousWord = inkWord Next inkWord Next lineNode
