Changing the size and style of an object over time
Using the Time Control Panel, you can make an object change its size
over time as well as perform other effects such as fades and color transi-
tions. This is done through the use of keyframes that you place at strate-
gic positions throughout the moving path. By changing the attributes of an
object at each keyframe, you cause it to change over time.
To change an objects size and style over time:
Select the object you want to change with the Moving Path tool. The
1.
moving path of the object appears.
Move the Preview slider in the Keyframe Controller to the frame in
2.
the path where you want the object to change. The object moves to
that frame position on the moving path.
Click the Add Keyframe button on the Time Control Panel. A
3.
keyframe is added to the Keyframe slider. (Keyframes are explained in
detail in the 'Using keyframe controls' section, page 164)
Change the style and size of the object using the Object Style Panel as
4.
well as the resize buttons on the Attribute toolbar. If you are changing
the style, any changes to the fill color options produces a fade effect
from one to the other, as long as two fill colors are of the same type,
for example, going from a gradient fill to another gradient fill. If the
types are different, no fade occurs and the style changes only at the
second keyframe position.
You can also control the transparency of the object as it moves over
time by adjusting the control points in the Fade graph. Moving a
control point upward makes the object more transparent: downward
less transparent.
Repeat steps 3 and 4 to add more keyframes. (To edit an object at an
5.
existing keyframe position, you must first make it active by clicking on
its keyframe in the Keyframe slider.)
