Ramp to Final Value: This option grows or shrinks the object from its original size to
the specified percentage plus the original scale in the Scale To parameter. If the behavior
is shortened in the Timeline, the Grow/Shrink effect goes faster.
Natural Scale: Enabled by default, this option uses an exponential curve to allow the
animation to progress slowly when the scale values are small and speed up when the
values are large. This creates the illusion that the scaling is occurring at a constant
speed.
Scale Rate/Scale To: Depending on the command chosen in the Increment pop-up menu,
the Scale Rate or Scale To parameter defines the speed and magnitude of the effect. This
parameter can be expanded to reveal X and Y subparameters by clicking the disclosure
triangle to the left. This lets you adjust the horizontal or vertical scale independently.
Curvature: This parameter lets you adjust the acceleration with which this behavior
transitions from the original to the final size. Higher Curvature values result in an easing
into and out of the effect, where the object slowly starts to change size, and this change
gradually speeds up as the behavior continues. Because Curvature is defined by the length
of the behavior in the Timeline, minus the End Offset, it does not affect the overall duration
of the effect
Note: The Curvature parameter is not available when the Increment parameter is set to
Natural Scale.
End Offset: A slider that lets you offset the end of the behavior’s effect relative to the
last frame of its position in the Timeline, in frames. Adjust this parameter to make the
behavior stop before the actual end of the behavior in the Timeline. Use this slider to
offset the end of the Grow/Shrink effect from the end of the object.
