Top-level functions

ShadowContext

android 
fun ShadowContext(): ShadowContext

Create a new ShadowContext

lerp

Cmn 
fun lerp(a: Shadow?, b: Shadow?, t: Float): Shadow?

Linearly interpolate between two Shadows.

The t argument represents position on the timeline, with 0.0 meaning that the interpolation has not started, returning a (or something equivalent to a), 1.0 meaning that the interpolation has finished, returning b (or something equivalent to b), and values in between meaning that the interpolation is at the relevant point on the timeline between a and b.

The interpolation can be extrapolated beyond 0.0 and 1.0, so negative values and values greater than 1.0 are valid (and can easily be generated by curves).

If a or b are both null, this will return null. If only one of the arguments is null, the null argument will be replaced with a transparent copy of the non-null argument

Parameters
a: Shadow?

Start Shadow at t = 0f
b: Shadow?

End Shadow at t = 1f
t: Float

Position on the timeline
Returns
Shadow?
