Esempi

Nell'esempio seguente viene illustrato l'utilizzo del metodo GetStrokeCaps.The following example demonstrates how to use the GetStrokeCaps method. Per eseguire questo esempio, incollare il codice in un Windows Form.To run this example, paste the code into a Windows Form. Gestire Paint l'evento del form e chiamare DrawCaps dal metodo di gestione Paint degli eventi del form, passando e come PaintEventArgs.Handle the form's Paint event and call DrawCaps from the form's Paint event-handling method, passing e as PaintEventArgs.
