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 key frames that you place at strate-
gic positions throughout the moving path. By changing the attributes of an
object at each key frame, 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 Key frame 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 Key frame button on the Time Control Panel. A key
3.
frame is added to the Key frame slider. (Key frames are explained in
detail in the "Using key frame controls" section, page 188.)
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 key frame 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 key frames. (To edit an object at an
5.
existing key frame position, you must first make it active by clicking
on its key frame in the Key frame slider.)
