设置或返回 Single 类型值,该值代表减速过程持续时间的百分比。例如,数值 0.9 表示减速过程以默认速度启动,经过动画持续时间的 10% 之后开始减速。可读写。
expression.Decelerate
expression 必选。该表达式返回“应用于”列表中的对象之一。
本示例添加一个形状并添加一个动画,该动画以默认速度启动,在动画完成 70% 以后开始减速。
Sub AddShapeSetTiming()
Dim effDiamond As Effect
Dim shpRectangle As Shape
'Adds rectangle and sets animation effect
Set shpRectangle = ActivePresentation.Slides(1).Shapes _
.AddShape(Type:=msoShapeRectangle, Left:=100, _
Top:=100, Width:=50, Height:=50)
Set effDiamond = ActivePresentation.Slides(1).TimeLine _
.MainSequence.AddEffect(Shape:=shpRectangle, _
effectId:=msoAnimEffectPathDiamond)
'Slows the effect after seventy percent of the animation has finished
With effDiamond.Timing
.Decelerate = 0.3
End With
