AnimationDescription 类

定义

Windows.UI.Core.AnimationMetrics

公开对特定目标执行的单个动画效果的集合，以构成完整的 Windows 不透明度、缩放或转换动画。

示例

此示例演示如何创建 AnimationDescription 对象及其用法。 假定 先前 已分配效果参数和 目标 参数。

using Windows.UI.Core.AnimationMetrics;

AnimationDescription animationDescription = new AnimationDescription(effect, target);

TimeSpan sd = animationDescription.StaggerDelay;
float tsf = animationDescription.StaggerDelayFactor;
TimeSpan dl = animationDescription.DelayLimit;
int zo = animationDescription.ZOrder;

foreach (var animation in animationDescription.Animations)
{
    switch (animation.Type)
    {
        case PropertyAnimationType.Scale:
            {
                ScaleAnimation scale = animation as ScaleAnimation;
                // Retrieve scale animation metrics.
            }
            break;
        case PropertyAnimationType.Translation:
            {
                TranslationAnimation scale = animation as TranslationAnimation;
                // Retrieve translation animation metrics.
            }
            break;
        case PropertyAnimationType.Opacity:
            {
                OpacityAnimation opacity = animation as OpacityAnimation;
                // Retrieve opacity animation metrics.
            }
            break;
    }

    TimeSpan delay = animation.Delay;
    TimeSpan duration = animation.Duration;
    Point c1 = animation.Control1;
    Point c2 = animation.Control2;
}

构造函数

AnimationDescription(AnimationEffect, AnimationEffectTarget)

创建具有特定动画和目标的 AnimationDescription 对象。

属性

Animations	获取与 AnimationDescription 对象关联的动画的集合。
DelayLimit	获取要应用于目标中对象的集合的动画的最大累积延迟时间。
StaggerDelay	获取将动画效果应用到包含多个 对象的目标中的每个 对象之间的时间。 StaggerDelay 以及 StaggerDelayFactor 和 DelayLimit 是用于控制动画效果相对计时的三个元素之一。
StaggerDelayFactor	获取一个乘数，该乘数应用于交错延迟的每个匹配项，按该量增加或减少上一个延迟实例。
ZOrder	获取相对于同一动画效果中其他 AnimationDescription 对象的 AnimationDescription 对象的 z 顺序位置。   具有较高 z 顺序封面的 AnimationDescription 对象以较低的 z 顺序转换。
