• Min Speed: A slider that adjusts the minimum threshold of speed sensitivity. Speed
values below the minimum value are remapped to 0. For Opacity and Width, those
values do not appear. For Spacing, Angle, and Jitter, the values are not modified. If the
Min Speed and Max Speed (described below) parameters are plotted on a graph, Min
Speed represents the minimum value, or 0. The area of the graph between Min Speed
and Max Speed is remapped to the output values.
• Max Speed: A slider that adjusts the maximum threshold of speed sensitivity. Speed
values above the maximum value are remapped to 1. For Opacity, Width, Spacing, Angle,
and Jitter, those values will have the greatest effect. If the Min Speed and Max Speed
parameters are plotted on a graph, Max Speed represents the maximum value, or 1. The
area of the graph between Min Speed and Max Speed is remapped to the output values.
• Scale: A slider that determines the magnitude of the effect. The Scale slider defines
the output range for the dabs based on the mapped values between minimum (0) and
maximum (1) speed, multiplied by the value defined in the slider (or adjacent value
slider). This amount is then applied to the channel (width, opacity, and so on) by
multiplying (for width, opacity, spacing, and jitter) or adding (for angle). This control is
independent of the Scale parameter in the Stroke pane of the Shape Inspector.
• Invert: A checkbox that, when selected, inverts the attributes of the stroke created by
the behavior. For example, if pen speed is set to affect the width of the stroke, thin
areas of the stroke become wide and wide areas become thin when the checkbox is
selected.
Apply Pen Tilt behavior in Motion
When you use a Wacom stylus and tablet to create paint strokes with the Paint Stroke tool,
the Apply Pen Tilt behavior controls the width, opacity, spacing, angle, or jitter of the paint
stroke based on the tilt of the pen.
Note: You can use a combination of Apply Pen Tilt shape behaviors to affect more than one
parameter (such as Opacity, Width, or Jitter) of the stroke using the same tilt data.
You can adjust the Apply Pen Tilt behavior using the following controls in the Behaviors
Inspector:
• Apply To: A pop-up menu that sets how your paint stroke is affected by the tilt of your
pen as you draw. There are five options:
• Width: The tilt of the stylus affects the width of the stroke. The greater the tilt, the
wider the stroke.
• Opacity: The tilt of the stylus affects the opacity of the stroke. The greater the tilt,
the more opaque the stroke.
• Spacing: The greater the tilt of the stylus, the greater the spacing between stroke
dabs.
• Angle: The greater the tilt of the stylus, the larger the value of the angle of the
stroke.
• Jitter: The greater the tilt of the stylus, the larger the amount of jitter on the stroke.
Jitter randomizes the position of the paint dabs so they appear more like particles.
