Ejemplos

El ejemplo siguiente está diseñado para su uso con Windows Forms y requiere PaintEventArgse, que es un parámetro del controlador de eventos Paint. El código realiza las siguientes acciones:

• Crea un rectángulo y lo dibuja en la pantalla en negro

• Crea un segundo rectángulo que interseca con el primero y lo dibuja en la pantalla en rojo.

• Crea una región mediante el primer rectángulo y crea una segunda región mediante el segundo rectángulo.

• Obtiene el complemento de esa primera región cuando se combina con la segunda región.

• Rellena el área de complemento con azul y la dibuja en la pantalla.

Observe que el área de la segunda región que no se interseca con la primera región es azul coloreado.
