ScaleAnimation (inherits Animation)

The ScaleAnimation scales the size of the target element by the given scaleFactor (i.e. a scaleFactor of .5 will shrink it in half and a scaleFactor of 2.0 will double it). If scaleFont is true, the size of the font will also scale with the element. If center is true, then the element's center will not move as it is scaled. It is important to note that the target must be positioned (i.e. absolutely) so that setting its top/left properties will change its location in order for center to have an effect.

Client properties

Name	Description
center	Whether the target should stay centered while scaling.
fontUnit	Unit of the font, which is only used if scaleFont is true. The default value is 'pt'.
scaleFactor	The amount to scale the target (a scaleFactor of .5 will shrink it in half and a scaleFactor of 2.0 will double it). The default value is 1, which does no scaling.
scaleFont	Whether the font should be scaled along with the size.
unit	Length unit for the size of the target. The default value is 'px'.

Client methods

Name	Description
constructor(target, duration, fps, scaleFactor, unit, center, scaleFont, fontUnit)
getAnimatedValue(percentage)	Get the amount to scale the target.
onEnd()	The onEnd method is called just after the animation is played each time.
onStart()	The onStart method is called just before the animation is played each time.
setValue(scale)	Scale the target by the given percentage.

Client properties
