Ejemplos

El ejemplo de código 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 lápices rojos y verdes.

• Crea siete puntos para definir una curva.

• Dibuja seis líneas rectas rojas entre los siete puntos para formar un polígono incompleto.

• Define el desplazamiento de punto inicial y el número de segmentos.

• Define la tensión.

• Dibuja una curva verde abierta (comenzando en el tercer punto) hasta los últimos cinco puntos.

El método establece la tensión en 1,0.

Comentarios

Este método dibuja una spline cardinal que pasa por cada punto de la matriz.

La matriz de puntos debe contener al menos tres PointF estructuras para que se dibuje la curva.

El valor del offset parámetro especifica el número de elementos que se van a omitir en la matriz. El primer elemento después de los elementos omitidos representa el punto inicial de la curva.

El valor del numberOfSegments parámetro especifica el número de segmentos, después del punto inicial, que se va a dibujar en la curva. El valor del numberOfSegments parámetro debe ser al menos 1. El valor del offset parámetro más el valor del numberOfSegments parámetro debe ser menor que el número de elementos de la matriz del points parámetro.

El tension parámetro determina la forma de la spline. Si el valor del tension parámetro es 0,0F, este método dibuja segmentos de línea recta para conectar los puntos. Normalmente, el tension parámetro es menor o igual que 1,0F. Los valores de más de 1.0F generan resultados inusuales.

Comentarios

Este método dibuja una spline cardinal que pasa por cada punto de la matriz.

La matriz de puntos debe contener al menos tres Point estructuras para que se dibuje una curva.

El tension parámetro determina la forma de la spline. Si el valor del tension parámetro es 0,0F, este método dibuja segmentos de línea recta para conectar los puntos. Normalmente, el tension parámetro es menor o igual que 1,0F. Los valores de más de 1.0F generan resultados inusuales.

Ejemplos

El ejemplo de código 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 lápices rojos y verdes.

• Crea siete puntos para definir una curva.

• Dibuja seis líneas rectas rojas entre los siete puntos para formar un polígono incompleto.

• Dibuja una curva verde abierta a través de los siete puntos.

El método usa una tensión predeterminada de 0,5.
