Stroke Pane Controls in the Inspector
Once an airbrush or image paint stroke has been created using the Paint Stroke tool, a
set of paint stroke controls becomes available, combining controls similar to those of a
particle system or replicator. Use these controls to set the Stroke Color Mode and Brush
Scale parameters, and to adjust the Opacity, Spacing, Width, and Angle Over Stroke
parameters.
Stroke Pane Parameters
The Stroke pane becomes available when Airbrush or Image is selected from the Brush
Type pop-up menu in the Style pane.
Stroke Color Mode: Use this pop-up menu to specify how the color is applied to the
stroke over its length. There are three options:
• Use Brush Color: Uses the color of the brush as defined by the Brush Color parameter
in the Style pane. The stroke is a solid color over its length. When you choose Use Brush
Color from the Stroke Color Mode pop-up menu, the Opacity Over Stroke control
becomes available.
• Color Over Stroke: Dabs are tinted based on their position over the length of the paint
stroke. When you choose this option, the Color Over Stroke control becomes available.
• Pick From Color Range: Dabs are tinted at random, with the range of possible colors
defined by a gradient editor. A point on the gradient is randomly chosen, so the relative
sizes of each color region determine the frequency of the color being used.
