•
Opacity: The faster you move the pen, the less opaque the stroke. To adjust the opacity of
the dabs after the stroke is created, use the opacity controls in the Style or Stroke pane.
•
Spacing: The faster you move the pen, the greater the spacing between the dabs of the
stroke. To adjust the spacing of the dabs after the stroke is created, use the spacing controls
in the Style or Stroke pane.
•
Angle: The faster you move the pen, the greater the angle of the stroke dabs. To adjust the
angle of the dabs after the stroke is created, use the angle controls in the Stroke pane.
•
Jitter: The faster you move the pen, the larger the amount of jitter on the stroke. Jitter
randomizes the position of the paint dabs so they appear more like particles. To adjust the
jitter of the dabs after the stroke is created, use the jitter controls in the Stroke pane.
•
Write On: A checkbox that, when selected, allows a stroke to be “painted” on the Canvas over
time. For more information, see
Write On on page 881.
•
Smoothing: A checkbox that, when selected, creates a smoother stroke with fewer control
points. Paint strokes drawn with smoothing on are created as bezier shapes. Paint strokes
drawn with smoothing off are created as linear shapes.
•
Shape Style: A pop-up menu that specifies a preset shape style (from the Library) to the
selected shape. You can also save any custom shape style to the Library using this pop-up
menu. Any stroke (shape) presets you have saved to the Library also appear in this list.
•
Sketch area: An empty field where brush styles can be sampled in combination with the
current Paint Stroke Tool HUD settings.
Convert shape outlines to paint strokes
You can convert a shape outline into a paint stroke by modifying the Brush Type in the Inspector.
After a shape outline is assigned a different brush type, paint stroke parameters become
available. You can modify and animate its brush parameters, as well as apply the Sequence
Paint behavior.
