4 In the Style pane of the Shape tab, choose Airbrush from the Brush Type pop-up menu.
Once the Brush Type is changed to Airbrush (or Image), the following occurs:
• The stroke softens because it is using a soft brush type. A paint stroke is comprised of
dabs and the brush type is the source for the dabs. The brush profile can be modified
to vary opacity within the brush. You can apply a custom opacity gradient to the brush
profile.
• The Stroke pane becomes available. Use the Stroke pane to set the Stroke Color mode
and Brush Scale parameters, and to adjust various options.
• The Advanced pane becomes available. The Advanced pane contains a single group
of controls that allow the dabs of a paint stroke to be animated like particles. For more
information on Dynamics, see
Advanced Pane Controls In the Inspector .
Note: When a paint stroke is created using the Paint Stroke tool in the Toolbar, additional
stylus parameters appear in the Advanced pane.
5 Use the controls in the Style, Stroke, and Advanced panes of the Shape Inspector to
modify or animate your paint stroke.
