Ejemplos

El ejemplo de código siguiente está diseñado para su uso con Windows Forms y requiere PaintEventArgse, un objeto de evento OnPaint. El código realiza las siguientes acciones:

• Crea una ruta de acceso.

• Agrega varias figuras a la ruta de acceso.

• Dibuja la ruta de acceso a la pantalla.

• Clona una copia de esa ruta de acceso.

• Dibuja la nueva ruta de acceso a la pantalla.

Observe que la llamada al método Clone debe convertirse como un GraphicsPath.
