To add feathering to an object’s edges:
1. Click the triangular opener for the Feathering parameter category.
2. Adjust the Bias, Hor (horizontal), and Vert (vertical) sliders.
Working with Vector-Based Objects
Intraframe effects are vector-based objects. Vector-based objects have several advantages over
bitmapped objects. For example, you can create and edit vector-based objects with much greater
precision than you can bitmapped objects. Also, vector-based objects are not subject to problems
such as artifacting when you rescale them.
Before you begin working with the paint and editing tools included in the Intraframe effects, you
must understand the basics of working with vector-based objects and Bézier curves.
The Elements of Vector-Based Objects
The objects you paint, the matte keys you draw, and the brush templates that appear in the Brush
Preview window include a control point at the midpoint of each line or curve, also known as a join.
The portion of the line or curve on each side of the control point is called a segment. The control
point controls the direction of each segment as it passes through the join.
Control points for a painted object are visible when you select an object with the Selection tool and
then click the Reshape tool. Also, when you click a brush template in the Effect Editor, the brush
head displays visible control points in the Brush Preview window.
A control point at the midpoint of a curve
The following illustration shows the three types of joins:
Left to right: straight-edge join, smooth join, and corner join
A control point associated with a smooth join or a corner join describes a Bézier curve. Clicking a
control point makes it the active join. Tangents called direction bars appear on each side of the
control point associated with a Bézier curve. At the end of each direction bar is a direction handle.
