Class AlphaFunction

Definition

Namespace:

Tizen.NUI

Assembly:

Tizen.NUI.dll

Alpha functions are used in animations to specify the rate of change of the animation parameter over time.
Understanding an animation as a parametric function over time, the alpha function is applied to the parameter of the animation before computing the final animation value.

public class AlphaFunction : Disposable, IDisposable

Inheritance

object

Disposable

AlphaFunction

Implements

System.IDisposable

Constructors

AlphaFunction()

The default constructor.
Creates an alpha function object with the default built-in alpha function.

Declaration

public AlphaFunction()

AlphaFunction(BuiltinFunctions)

The constructor.
Creates an alpha function object with the built-in alpha function passed as a parameter to the constructor.

Declaration

public AlphaFunction(AlphaFunction.BuiltinFunctions function)

Parameters

Type	Name	Description
AlphaFunction.BuiltinFunctions	function	One of the built-in alpha functions.

AlphaFunction(Vector2, Vector2)

The constructor.
Creates a bezier alpha function. The bezier will have the first point at (0,0) and the end point at (1,1).

Declaration

public AlphaFunction(Vector2 controlPoint0, Vector2 controlPoint1)

Parameters

Type	Name	Description
Vector2	controlPoint0	A Vector2 which will be used as the first control point of the curve.
Vector2	controlPoint1	A Vector2 which will be used as the second control point of the curve.

Remarks

The x components of the control points will be clamped to the range [0, 1] to prevent non-monotonic curves.

AlphaFunction(Delegate)

The constructor.
Creates an alpha function object with the user-defined alpha function.

Declaration

public AlphaFunction(Delegate func)

Parameters

Type	Name	Description
Tizen.System.Delegate	func	User defined fuction. It must be a method formatted as float alphafunction(float progress)

Fields

swigCMemOwn

swigCMemOwn.

Declaration

protected bool swigCMemOwn

Field Value

Type	Description
bool

Methods

Dispose(DisposeTypes)

To make the AlphaFunction instance be disposed.

Declaration

protected override void Dispose(DisposeTypes type)

Parameters

Type	Name	Description
DisposeTypes	type

Overrides

Disposable.Dispose(DisposeTypes)

GetBezierControlPoints(out Vector2, out Vector2)

Retrives the control points of the alpha function.

Declaration

public void GetBezierControlPoints(out Vector2 controlPoint0, out Vector2 controlPoint1)

Parameters

Type	Name	Description
Vector2	controlPoint0	A Vector2 which will be used as the first control point of the curve.
Vector2	controlPoint1	A Vector2 which will be used as the second control point of the curve.

GetBuiltinFunction()

Returns the built-in function used by the alpha function.
In case no built-in function has been specified, it will return AlphaFunction::DEFAULT.

Declaration

public AlphaFunction.BuiltinFunctions GetBuiltinFunction()

Returns

Type	Description
AlphaFunction.BuiltinFunctions	One of the built-in alpha functions.

GetMode()

Returns the functioning mode of the alpha function.

Declaration

public AlphaFunction.Modes GetMode()

Returns

Type	Description
AlphaFunction.Modes	The functioning mode of the alpha function.
