Ejemplos

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

• Crea una matriz de puntos que forman un rectángulo.

• Dibuja esta matriz de puntos (en la pantalla antes de aplicar una transformación de escalado (el rectángulo azul).

• Crea una matriz y la escala en 3 en el eje X y 2 en el eje Y.

• Aplica esta transformación de matriz a la matriz de puntos.

• Dibuja la matriz transformada en la pantalla (el rectángulo rojo).

Observe que el rectángulo rojo se ha escalado por un factor de 3 en el eje x y en 2 en el eje Y, incluida la esquina superior izquierda del rectángulo (el punto inicial del rectángulo).
