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.

create
Interpolator create (Path path)
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)
.
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
|
create
Interpolator create (float controlX1, float controlY1, float controlX2, float controlY2)
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
|
create
Interpolator create (float controlX, float controlY)
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
