背水一战 Windows 10 (14) - 动画: 线性动画, 关键帧动画



作者:webabcd


介绍
背水一战 Windows 10 之 动画

  • 线性动画 - ColorAnimation, DoubleAnimation, PointAnimation
  • 关键帧动画 - ColorAnimationUsingKeyFrames, DoubleAnimationUsingKeyFrames, PointAnimationUsingKeyFrames, ObjectAnimationUsingKeyFrames



示例
1、演示线性动画的应用

    <Grid Background="Transparent">
        
        <!--
            线性动画一共有 3 种:ColorAnimation, DoubleAnimation, PointAnimation, 它们均继承自 Timeline
        
            Storyboard.TargetName - 附加属性,要进行动画处理的对象的名称
            Storyboard.TargetProperty - 附加属性,要进行动画处理的对象的属性
            BeginTime - 时间线在被触发 BeginTime 的时间后才能开始播放
                TimeSpan - [-][日.]时:分:秒[.1位到7为的秒后的小数](可为正;可为负;可为空;默认值为 0)
            From - 动画的起始值
            To - 动画的结束值
            By - 动画从起始值开始计算,所需变化的总量(To 优先于 By)
            Duration - 时间线的持续时间
                TimeSpan - [-][日.]时:分:秒[.1位到7为的秒后的小数]
                Automatic - 自动确定
                Forever - 无限长
            AutoReverse - 动画完成后是否要原路返回。默认值为 false
            RepeatBehavior - 动画重复播放的时间、次数或类型
                TimeSpan - [-][日.]时:分:秒[.1位到7为的秒后的小数]
                nx - 播放次数。1x, 2x, 3x 
                Forever - 永久播放
            SpeedRatio - 时间线的速率的倍数。默认值 1
            FillBehavior - 动画结束后的行为(System.Windows.Media.Animation.FillBehavior 枚举)
                FillBehavior.HoldEnd - 动画结束后,UI 保留动画后的状态。默认值
                FillBehavior.Stop - 动画结束后,UI 恢复为动画前的状态
        
        
            注意:
            1、在 WinRT 中为了流畅的体验,部分动画被优化成了“独立动画”,即动画不依赖于 UI 线程
            2、但是也有一部分动画无法优化成“独立动画”,我们把这类动画称作“依赖动画”,其需要在 UI 线程上运行
            3、通过将 EnableDependentAnimation 设置为 true(默认为 false),开启“依赖动画”
            4、通过将 Timeline.AllowDependentAnimations 设置为 false(默认为 true),可以全局禁止开启“依赖动画”
        
            Independent Animation - 独立动画
            Dependent Animation - 依赖动画
