Public Property DecelerationRatio As Double

Property Value

Double

A value between 0 and 1, inclusive, that specifies the percentage of the timeline's Duration spent decelerating the passage of time from its maximum rate to zero. If the timeline's AccelerationRatio property is also set, the sum of DecelerationRatio and AccelerationRatio must be less than or equal to 1. The default value is 0.

Exceptions

ArgumentException

DecelerationRatio is less than 0 or greater than 1.

InvalidOperationException

The sum of AccelerationRatio and DecelerationRatio exceeds 1.

Remarks

Use the DecelerationRatio property to create animations that slow down before stopping. The DecelerationRatio property is useful for creating ease-in effects or making movement seem more natural. Use the AccelerationRatio and DecelerationRatio properties together to create animations that start slowly, speed up, and then slow down again before finishing.
