Parámetros

speedRatio
Double

Valor finito mayor que cero que es la nueva relación de velocidad interactiva del guión gráfico.A finite value greater than zero that is the new interactive speed ratio of the storyboard. Este valor se multiplica por el valor SpeedRatio del guión gráfico para determinar la velocidad efectiva del guión gráfico.This value is multiplied against the storyboard's SpeedRatio value to determine the storyboard's effective speed. Este valor no sobrescribe la propiedad SpeedRatio del guión gráfico.This value does not overwrite the storyboard's SpeedRatio property. Por ejemplo, llamar a este método y especificar una relación de velocidad interactiva de 3 en un guión gráfico con una SpeedRatio de 0.5 asigna al guión gráfico una velocidad efectiva de 1.5.For example, calling this method and specifying an interactive speed ratio of 3 on a storyboard with a SpeedRatio of 0.5 gives the storyboard an effective speed of 1.5.

Un guion gráfico controlable puede pausar, reanudar, buscar, detener y quitar.A controllable storyboard can pause, resume, seek, stop, and be removed. Para que un guion gráfico pueda controlarse en el código, debe usar la sobrecarga adecuada del método Begin del guión gráfico true y especificar para que sea controlable.To make a storyboard controllable in code, you must use the appropriate overload of the storyboard's Begin method and specify true to make it controllable. Como ejemplo, vea Cómo: Controlar un guión gráfico después desu inicio.For an example, see How to: Control a Storyboard After It Starts.
