Class AlphaFunction
Definition
- 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.

Constructors
View SourceAlphaFunction()
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

Methods
View SourceDispose()
To make the AlphaFunction instance be disposed.
Declaration
public void Dispose()
Dispose(DisposeTypes)
To make the AlphaFunction instance be disposed.
Declaration
protected virtual void Dispose(DisposeTypes type)
Parameters
Type | Name | Description |
---|---|---|

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. |
