Esempi

Nell'esempio seguente viene illustrato come riprodurre a ciclo continuo un oggetto ContextNodeBaseCollection dall'oggetto InkAnalyzerBase. Viene utilizzato il metodo FindNodesOfType di un oggetto InkAnalyzerBase denominato theInkAnalyzerBase. In questo esempio viene illustrato come riprodurre a ciclo continuo tutti i nodi di riga. Se esistono due nodi di parola di input penna con la stessa parola, questi vengono contrassegnati in rosso.
