Animation settings

This section describes how Animation playback can be customized.

Easing functions

Easing functions describe how quickly an animated property changes from its starting value into its ending value across the animation time. Avalonia.Animation.Easings contains the following easings:

Default
LinearEasing

Ease-In	Ease-Out	Ease-In-Out
SineEaseIn	SineEaseOut	SineEaseInOut
QuadraticEaseIn	QuadraticEaseOut	QuadraticEaseInOut
CubicEaseIn	CubicEaseOut	CubicEaseInOut
QuarticEaseIn	QuarticEaseOut	QuarticEaseInOut
QuinticEaseIn	QuinticEaseOut	QuinticEaseInOut
ExponentialEaseIn	ExponentialEaseOut	ExponentialEaseInOut
CircularEaseIn	CircularEaseOut	CircularEaseInOut
BackEaseIn	BackEaseOut	BackEaseInOut
ElasticEaseIn	ElasticEaseOut	ElasticEaseInOut
BounceEaseIn	BounceEaseOut	BounceEaseInOut

Additionally, you can provide your own easing by deriving from Easing or by providing parameters to SplineEasing or SpringEasing.

FillModes

The FillMode attribute of an Animation defines how the animated property persists after an animation completes and during delays in-between runs.

The following table describes the supported behaviors:

Value	Description
None	Value will not persist after animation nor the first value will be applied when the animation is delayed.
Forward	The last interpolated value will be persisted to the target property.
Backward	The first interpolated value will be displayed on animation delay.
Both	Both Forward and Backward behaviors will be applied.

PlaybackDirection

PlaybackDirection defines how the Animation will be played. The following table describes the possible settings:

Value	Description
Normal	The animation is played normally.
Reverse	The animation is played in reverse direction.
Alternate	The animation is played forwards first, then backwards.
AlternateReverse	The animation is played backwards first, then forwards.

IterationCount

The IterationCount on an Animation element sets how many times it is to be replayed. There are two formats for this setting:

Value	Description
N	(N is an integer) - play N times. N can be zero.
Infinite	Repeats forever
