GraphicsPath.AddCurve Método

Definición

Agrega una curva spline a la figura actual.Adds a spline curve to the current figure. Se utiliza una curva spline cardinal porque la curva recorre todos los puntos de la matriz.A cardinal spline curve is used because the curve travels through each of the points in the array.

Parámetros

points
PointF[]

Matriz de estructuras PointF que representa los puntos que definen la curva.An array of PointF structures that represents the points that define the curve.

offset
Int32

Índice del elemento de la matriz points que se usa como primer punto de la curva.The index of the element in the points array that is used as the first point in the curve.

numberOfSegments
Int32

Número de segmentos usados para dibujar la curva.The number of segments used to draw the curve. Un segmento es, en realidad, una línea que conecta dos puntos.A segment can be thought of as a line connecting two points.

tension
Single

Valor que especifica la inclinación de la curva entre puntos de control.A value that specifies the amount that the curve bends between control points. Los valores mayores que 1 producen resultados impredecibles.Values greater than 1 produce unpredictable results.

El usuario debe conservar los puntos originales si es necesario.The user must keep the original points if they are needed. Los puntos originales se convierten en puntos de control Bézier cúbicos internamente, por lo que no hay ningún mecanismo para devolver los puntos originales.The original points are converted to cubic Bézier control points internally, therefore there is no mechanism for returning the original points.

La curva comienza en el punto de la matriz especificado por offsete incluye el número de puntos (segmentos) especificados por numberOfSegments.The curve begins at the point in the array specified by offset, and includes the number of points (segments) specified by numberOfSegments.

El siguiente ejemplo de código está diseñado para su uso con Windows Forms y requiere PaintEventArgse, un objeto de evento de OnPaint.The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, an OnPaint event object. El código realiza las siguientes acciones:The code performs the following actions:

  • Crea una matriz de cuatro puntos (que representa una curva spline cardinal).Creates an array of four points (representing a cardinal spline).

  • Crea una ruta de acceso y usa la matriz de puntos, agrega la curva a la ruta de acceso.Creates a path and using the array of points, adds the curve to the path.

  • Dibuja la ruta de acceso a la pantalla.Draws the path to the screen.

Tenga en cuenta que mientras que la matriz contiene cuatro puntos, solo hay tres segmentos, que es el número especificado en el tercer argumento de la llamada a AddCurve.Notice that while the array holds four points, there are only three segments, which is the number specified in the third argument of the call to AddCurve.
