Aggiornamento: novembre 2007
Rappresenta un oggetto ContextNode per un insieme di tratti che costituisce un raggruppamento logico utilizzato per formare una parola riconoscibile.
Spazio dei nomi: Microsoft.Ink

Esempi
Nell'esempio seguente viene eseguito il ciclo in tutti gli oggetti InkWordNode di un oggetto InkAnalyzer, theInkAnalyzer, quindi vengono disegnate le linee che mostrano il rettangolo di delimitazione ruotato, l'ascendente, il discendente, la linea mediana e la linea di base. Le linee vengono disegnate su un oggetto Panel, theNotesPanel.
Dim panelGraphics As Graphics = theNotesPanel.CreateGraphics()
Dim theRenderer As Renderer = theInkCollector.Renderer
' Loop through all of the ink words
Dim inkWords As ContextNodeCollection = _
theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.InkWord)
Dim inkWord As InkWordNode
For Each inkWord In inkWords
' Show rotated bounding box in blue
' Convert corners to pixel coordinates
Dim corners As Point() = inkWord.GetRotatedBoundingBox()
theRenderer.InkSpaceToPixel(panelGraphics, corners)
' Draw the rectangle
panelGraphics.DrawPolygon(New Pen(Color.Blue), corners)
' Show the ascender line in green
Dim ascenderPoints As Point() = inkWord.GetAscender()
' Convert to pixel coordinates
theRenderer.InkSpaceToPixel(panelGraphics, ascenderPoints)
panelGraphics.DrawLines(New Pen(Color.Green), ascenderPoints)
' Show the baseline in purple
Dim basePoints As Point() = inkWord.GetBaseline()
' Convert to pixel coordinates
theRenderer.InkSpaceToPixel(panelGraphics, basePoints)
panelGraphics.DrawLines(New Pen(Color.Purple), basePoints)
' Show the descender line in yellow
Dim descenderPoints As Point() = inkWord.GetDescender()
' Convert to pixel coordinates
theRenderer.InkSpaceToPixel(panelGraphics, descenderPoints)
panelGraphics.DrawLines(New Pen(Color.Yellow), descenderPoints)
' Show the mid line in brown
Dim midlinePoints As Point() = inkWord.GetMidline()
' Convert to pixel coordinates
theRenderer.InkSpaceToPixel(panelGraphics, midlinePoints)
panelGraphics.DrawLines(New Pen(Color.Brown), midlinePoints)
