Assembly: System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.
<timeline SpeedRatio="double"/>
Property Value
Type: System.DoubleA finite value greater than 0 that specifies the rate at which time progresses for this timeline, relative to the speed of the timeline's parent. If this timeline is a root timeline, specifies the default timeline speed. The value is expressed as a factor where 1 represents normal speed, 2 is double speed, 0.5 is half speed, and so on. The default value is 1.
Dependency property identifier field: SpeedRatioProperty
A timeline's SpeedRatio setting does not have an effect on its BeginTime; that time is relative to the timeline's parent or, if the timeline is a root timeline, the moment at which the timeline's clock was begun.
Momentary or nonlinear apparent speed changes to animations can be accomplished using spline animations.
