Constructor Detail

FadeTransition

public FadeTransition(TransitionManager transitionManager)

This constructor creates a FadeTransition with number of frames per second of Transition.DEFAULT_FPS and total transition time of Transition.DEFAULT_T milliseconds. It is similar to new FadeTransition(transitionManager, Transition.DEFAULT_FPS, Transition.DEFAULT_T)

Parameters:

transitionManager - the transition manager to be used to manage transitions

FadeTransition

public FadeTransition(TransitionManager transitionManager,
                      long fps,
                      long T)

This constructor creates a FadeTransition with fps number of frames per second and T total transition time in milliseconds.

Parameters:

transitionManager - the transition manager to be used to manage transitions

fps - number of frames per second

T - the total time the transition effect will take in milliseconds

Method Detail

initTransition

protected void initTransition(org.eclipse.swt.graphics.Image from,
                              org.eclipse.swt.graphics.Image to,
                              org.eclipse.swt.graphics.GC gc,
                              double direction)

Specified by:

stepTransition

protected void stepTransition(long t,
                              org.eclipse.swt.graphics.Image from,
                              org.eclipse.swt.graphics.Image to,
                              org.eclipse.swt.graphics.GC gc,

protected void endTransition(org.eclipse.swt.graphics.Image from,
                             org.eclipse.swt.graphics.Image to,
                             org.eclipse.swt.graphics.GC gc,
                             double direction)

Specified by:

endTransition in class Transition

setFadeOutStart

public void setFadeOutStart(double percentage)

Specifies when the fade-out effect is started as a percentage of the transition total time. For example, 0% means that the fade-out effect will start at the beginning of the transition.
percentage should have a value in the interval from 0 to 100 inclusive otherwise the passed value would be ignored leaving the previous value unchanged.

Parameters:

percentage - is a percentage of the transition total time.

setFadeOutStop

public void setFadeOutStop(double percentage)

Specifies when the fade-out effect is ended as a percentage of the transition total time. For example, 50% means that the fade-out effect will stop at the mid of the transition.
percentage should have a value in the interval from 0 to 100 inclusive otherwise the passed value would be ignored leaving the previous value unchanged.

Parameters:

percentage - is a percentage of the transition total time.

setFadeInStart

public void setFadeInStart(double percentage)

Specifies when the fade-in effect is started as a percentage of the transition total time. For example, 50% means that the fade-in effect will start at the mid of the transition.
percentage should have a value in the interval from 0 to 100 inclusive otherwise the passed value would be ignored leaving the previous value unchanged.

Parameters:

percentage - is a percentage of the transition total time.

setFadeInStop

public void setFadeInStop(double percentage)

Specifies when the fade-in effect is ended as a percentage of the transition total time. For example, 100% means that the fade-in effect will stop at the end of the transition.
percentage should have a value in the interval from 0 to 100 inclusive otherwise the passed value would be ignored leaving the previous value unchanged.

Parameters:

percentage - is a percentage of the transition total time.
