public ulong mode { construct set; get; }
The progress function logical id - either a value from the AnimationMode enumeration or a value returned by register_func.
public Timeline timeline { set; get; }
A Timeline instance used to drive the alpha function.

public static ulong register_closure (Closure closure)
Closure variant of register_func.
public static ulong register_func (AlphaFunc func)
Registers a global alpha function and returns its logical id to be used by set_mode or by Animation.

public Alpha ()
Creates a new Alpha instance.
public Alpha.full (Timeline timeline, ulong mode)
Creates a new Alpha instance and sets the timeline and animation mode.
public Alpha.with_func (Timeline timeline, owned AlphaFunc func)
Creates a new Alpha instances and sets the timeline and the alpha function.

public double get_alpha ()
Query the current alpha value.
public ulong get_mode ()
Retrieves the AnimationMode used by alpha.
public weak Timeline get_timeline ()
Gets the Timeline bound to alpha.
public void set_closure (Closure closure)
Sets the Closure used to compute the alpha value at each frame of the Timeline bound to alpha.
public void set_func (owned AlphaFunc func)
Sets the AlphaFunc function used to compute the alpha value at each frame of the Timeline bound to alpha.
public void set_mode (ulong mode)
Sets the progress function of alpha using the symbolic value of mode, as taken by the AnimationMode enumeration or using the value returned by register_func.
public void set_timeline (Timeline timeline)
Binds alpha to timeline.
