Applying Filters to Shapes
You can apply filters to shapes, like any other layer. When you apply a filter to a shape,
the shape remains editable, even though the filter changes it from a vector-based object
into a bitmapped object to perform the operation.
Shape with filter applied
You can apply filters to individual shapes or to a group that contains a number of shapes.
You can use filters to stylize shapes far beyond the options available in the Shape Inspector.
More importantly, you can use filters in conjunction with the Shape Inspector parameters
to customize a shape’s look, while preserving the ability to re-edit the shape later.
After 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.
