Esempio

L'esempio di codice seguente è progettato per l'uso con Windows Form e richiede PaintEventArgse, un oggetto evento Paint. Il codice esegue le azioni seguenti:

• Crea una matrice di punti che formano un rettangolo.

• Disegna questa matrice di punti (sullo schermo prima di applicare una trasformazione di ridimensionamento (il rettangolo blu).

• Crea una matrice e la ridimensiona di 3 nell'asse x e 2 nell'asse y.

• Applica questa trasformazione matrice alla matrice di punti.

• Disegna la matrice trasformata sullo schermo (rettangolo rosso).

Si noti che il rettangolo rosso è stato ridimensionato da un fattore pari a 3 nell'asse x e da 2 nell'asse y, incluso l'angolo superiore sinistro del rettangolo (il punto iniziale del rettangolo).
