Public Property AccelerationRatio As Double

Property Value

Double

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

Exceptions

ArgumentException

AccelerationRatio is less than 0 or greater than 1.

InvalidOperationException

The sum of AccelerationRatio and DecelerationRatio exceeds 1.

Remarks

Use the AccelerationRatio property to create animations that start slowly and then speed up as time progresses. The AccelerationRatio 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.
