Matriz de estructuras PointF que definen la curva spline.

tension

Single

Valor mayor o igual que 0,0 F que especifica la tensión de la curva.

fillmode

FillMode

Miembro de la enumeración FillMode que determina cómo se rellena la curva. Este parámetro es obligatorio, si bien se pasa por alto.

Ejemplos

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

• Crea lápices rojos y verdes.

• Crea siete puntos para definir la curva.

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

• Crea la configuración del modo de tensión y relleno.

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

El método usa una tensión de 1,0 y establece el modo de relleno en FillMode.Alternate.

Comentarios

Este método dibuja una spline cardinal cerrada que pasa por cada punto de la matriz. Si el último punto no coincide con el primer punto, se agrega un segmento de curva adicional desde el último punto al primer punto para cerrarlo.

La matriz de puntos debe contener al menos cuatro PointF estructuras.

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.
