ScaleAnimation - DevExpress/AjaxControlToolkit GitHub Wiki

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.
