public AnimationScaleTo(double sxTarget,
                        double syTarget)

Builds a "scaleTo" animation.

Parameters:

sxTarget - The final scale factor along the x-axis.

syTarget - The final scale factor along the y-axis.

Method Detail

step

public void step(double t)

Override this abstract to specify the effect of this animation.

Specified by:

step in class Animation

Parameters:

t - The parameter of this animation.

doStart

public void doStart()

Method called when this animation is started. This method does nothing. It can be redefined in derived classes.

Overrides:

doStart in class Animation

Animation.start()

setAnimatedElement

public Animation setAnimatedElement(CElement ce)

Sets the CElement that must be animated by this animation. If the canvas that must received animation events has not yet been set, it is set to the canvas to which belongs this CElement.

Overrides:

setAnimatedElement in class Animation

Parameters:

ce - The CElement to animate.

Returns:

this animation.

getScaleXTarget

public double getScaleXTarget()

Returns:

the final scale factor along the x-axis.

getScaleYTarget

public double getScaleYTarget()

Returns:

the final scale factor along the y-axis.

setScaleTarget

public AnimationScaleTo setScaleTarget(double sxTarget,
                                       double syTarget)

Sets the final scale factors along the x-axis and the y-axis.

Parameters:

sxTarget - The final scale factor along the x-axis.

syTarget - The final scale factor along the y-axis.

Returns:

this animation.
