Stroke pane
After you create an airbrush or image paint stroke, a set of paint stroke controls becomes
available in the Stroke pane. These controls are similar to those of a particle system or replicator.
Use them to set the Stroke Color Mode and Brush Scale parameters, and to adjust the Opacity,
Spacing, Width, and Angle Over Stroke parameters.
The Stroke pane is available only when Brush Type pop-up menu in the Style pane is set to
Airbrush or Image.
Stroke controls
•
Stroke Color Mode: A pop-up menu that specifies how 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.
•
Opacity Over Stroke: An opacity gradient editor that appears when Stroke Color Mode is set to
Use Brush Color. Use it to change the opacity of dabs based on their location on the stroke.
This gradient control is limited to grayscale values, which are used to represent varying levels
of transparency. White represents solid dabs, progressively darker levels of gray represent
decreasing opacity, and black represents complete transparency. A simple white-to-black
gradient represents a stroke that is solid at its start, but fades out gradually over its length
until finally vanishing at the end. For information on using gradient editors, see
Gradient
editor on page 135.
