Next, you need to create a corresponding target shape for each source shape you
created. Target shapes define the contour of deformation to which pixels identified by
each source shape are moved.
4 Create target shapes using the same shape-drawing techniques used in step 2.
Note: Another technique you can use to create a target shape quickly is to duplicate
the source shape by right-clicking it and choosing Duplicate Shape from the shortcut
menu. You can also choose Duplicate and Connect Shape (or press Control-D or
Command-D), in which case you can skip step 5. If you’re using either of these options,
you may want to animate the original source shape first, as the copied shape inherits
the animation.
As you create target shapes for each source shape, they remain yellow to indicate that
they’re still unassigned, and have no effect on the image.
To create the actual warping effect, you have to connect the shapes you created a pair
at a time.
5 To do this, use the following steps:
a Click the Connect Shapes button.
b Click a source shape that conforms to the actual position of the first feature you
identified.
c Immediately click the corresponding target shape you created.
Unassigned shapes are yellow.
