Примеры

The following example finds LineNode objects that contain any of the strokes in a StrokeCollection, selectedStrokes, and marks them as red.

Dim selectedLines As ContextNodeCollection = theInkAnalyzer.FindNodesOfType(ContextNodeType.Line, selectedStrokes)
Dim line As LineNode
For Each line In  selectedLines
    Dim stroke As Stroke
    For Each stroke In  line.Strokes
        stroke.DrawingAttributes.Color = Colors.Red
    Next stroke
Next line

ContextNodeCollection selectedLines =
    theInkAnalyzer.FindNodesOfType(ContextNodeType.Line,
    selectedStrokes);
foreach (LineNode line in selectedLines)
{
    foreach (Stroke stroke in line.Strokes)
        stroke.DrawingAttributes.Color = Colors.Red;
}
