class PathInterpolatorCompat

Helper for creating path-based Interpolator instances. On API 21 or newer, the platform implementation will be used and on older platforms a compatible alternative implementation will be used.

Summary

Public functions
`java-static Interpolator`	`create(path: Path)` Create an `Interpolator` for an arbitrary `Path`.
`java-static Interpolator`	`create(controlX: Float, controlY: Float)` Create an `Interpolator` for a quadratic Bezier curve.
`java-static Interpolator`	`create( controlX1: Float, controlY1: Float, controlX2: Float, controlY2: Float )` Create an `Interpolator` for a cubic Bezier curve.

Public functions

create

Added in 1.1.0

java-static fun create(path: Path): Interpolator

Create an Interpolator for an arbitrary Path. The Path must begin at (0, 0) and end at (1, 1). The x-coordinate along the Path is the input value and the output is the y coordinate of the line at that point. This means that the Path must conform to a function y = f(x).

The Path must not have gaps in the x direction and must not loop back on itself such that there can be two points sharing the same x coordinate.

Parameters
`path: Path`	the `Path` to use to make the line representing the `Interpolator`

Returns
`Interpolator`	the `Interpolator` representing the `Path`

java-static fun create(controlX: Float, controlY: Float): Interpolator

Create an Interpolator for a quadratic Bezier curve. The end points (0, 0) and (1, 1) are assumed.

Parameters
`controlX: Float`	the x coordinate of the quadratic Bezier control point
`controlY: Float`	the y coordinate of the quadratic Bezier control point

Returns
`Interpolator`	the `Interpolator` representing the quadratic Bezier curve

create

java-static fun create(
    controlX1: Float,
    controlY1: Float,
    controlX2: Float,
    controlY2: Float
): Interpolator

Create an Interpolator for a cubic Bezier curve. The end points (0, 0) and (1, 1) are assumed.

Parameters
`controlX1: Float`	the x coordinate of the first control point of the cubic Bezier
`controlY1: Float`	the y coordinate of the first control point of the cubic Bezier
`controlX2: Float`	the x coordinate of the second control point of the cubic Bezier
`controlY2: Float`	the y coordinate of the second control point of the cubic Bezier

Returns
`Interpolator`	the `Interpolator` representing the cubic Bezier curve
