Applying Filters to Shapes
You can apply filters to shapes, just like any other object. When you apply a filter to a
shape, it remains editable, even though the filter is changing it from a vector-based
object into a bitmapped object in order to perform the operation.
You can apply filters to individual shapes, or to a layer in which a number of shapes
have been nested. You can use filters to stylize shapes far beyond the options that are
available in the Shape tab of the Inspector. More importantly, you can use filters in
conjunction with the Shape tab parameters to interactively customize a shape’s look,
while preserving the ability to re-edit the shape at any time.
Important: Once you apply a filter to a shape, you can no longer smoothly increase the
size of that shape using the object’s transform controls. This is because filters change
shapes from vector objects to bitmapped objects. As a result, they scale like other
bitmapped objects, which display artifacts if they’re enlarged too much.
For more information on using filters, see “ Using Filters ” on page 701.
Animating Shapes
You can animate shapes using both behaviors and keyframes. Behaviors animate
parameters that transform an entire shape, such as Position, Rotation, and Scale.
Applying behaviors to shapes works the same as with any object in Motion, and
keyframed animation of any of these parameters is stored in the Transform.Position,
Transform.Rotation, and Transform.Scale animation parameters of the Keyframe Editor.
