备注

InkWordNode 对象不能包含任何子级。

示例

下面的示例遍历 InkAnalyzer (theInkAnalyzer) 中的所有 InkWordNode 对象，然后绘制显示旋转边框、上行字母线、下行字母线、中线和基线的线条。这些线条在一个 Panel (theNotesPanel) 上绘制。

    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)
    Next inkWord

    panelGraphics.Dispose()

End Sub 'inkWordMenuItem_Click

            Graphics panelGraphics = theNotesPanel.CreateGraphics();
            Renderer theRenderer = theInkCollector.Renderer;

            // Loop through all of the ink words
            ContextNodeCollection inkWords =
                theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.InkWord);
            foreach (InkWordNode inkWord in inkWords)
            {
                // Show rotated bounding box in blue
                // Convert corners to pixel coordinates
                Point[] corners = inkWord.GetRotatedBoundingBox();
                theRenderer.InkSpaceToPixel(panelGraphics, ref corners);
                // Draw the rectangle
                panelGraphics.DrawPolygon(new Pen(Color.Blue), corners);

                // Show the ascender line in green
                Point[] ascenderPoints = inkWord.GetAscender();
                // Convert to pixel coordinates
                theRenderer.InkSpaceToPixel(panelGraphics, ref ascenderPoints);
                panelGraphics.DrawLines(new Pen(Color.Green), ascenderPoints);

                // Show the baseline in purple
                Point[] basePoints = inkWord.GetBaseline();
                // Convert to pixel coordinates
                theRenderer.InkSpaceToPixel(panelGraphics, ref basePoints);
                panelGraphics.DrawLines(new Pen(Color.Purple), basePoints);

                // Show the descender line in yellow
                Point[] descenderPoints = inkWord.GetDescender();
                // Convert to pixel coordinates
                theRenderer.InkSpaceToPixel(panelGraphics, ref descenderPoints);
                panelGraphics.DrawLines(new Pen(Color.Yellow), descenderPoints);

                // Show the mid line in brown
                Point[] midlinePoints = inkWord.GetMidline();
                // Convert to pixel coordinates
                theRenderer.InkSpaceToPixel(panelGraphics, ref midlinePoints);
                panelGraphics.DrawLines(new Pen(Color.Brown), midlinePoints);
            }

            panelGraphics.Dispose();
