Changing stroke weight with Stylus Radius (PB only)
Under Brush Settings in the Vector Paint effects, the Stylus Radius option affects stylus
sensitivity. When you select this option, the pressure of the pen on the tablet changes the
weight of the stroke as it is drawn. Lighter pressure decreases the radius (creating a
thinner stroke), and increased pressure increases the radius (creating a wider one). The
Radius value setting indicates the maximum radius amount. Use the tablet settings to
adjust the pressure-width sensitivity for the pen.
Use the Effect Controls window to turn this option off and on: Select the Radius option for
Stylus under Vector Paint. When this option is turned on, an X appears in the Radius check
box and a checkmark appears by the Stylus command in the Vector Paint contextual
menu.
Note: You can choose Stylus Radius even when no tablet is installed. This affects strokes
when wiggling is enabled.
Using stylus pressure to affect opacity (PB only)
The pressure variation of the pen on the tablet alters the opacity of the stroke as you draw.
Light pressure results in lower opacity values, while increased pressure creates more
opaque strokes. The Opacity value defines the maximum of the Opacity range.
As with Stylus Radius, you can select and specify a stylus Opacity. When stylus Opacity is
active, a checkmark appears by the command on the Vector Paint contextual menu and
and an X appears in the Stylus Opacity check box in the Effect Controls window.
Selecting Preferences for stylus settings (PB only)
The following appear in the Vector Paint Preferences dialog box under Stylus Options:
Stylus Vendor (Mac OS only) If a tablet is installed, vendor information appears here. If
the system does not detect a stylus, "No stylus detected" appears.
Use High Res. Coordinates When this option is checked, data is recorded with high
resolution (if supported by the stylus). This setting overrides normal mouse coordinates to
use the higher resolution of the tablet, recording strokes with greater precision and
subpixel accuracy.
For other information about using your stylus with Vector Paint, see "Stylus Settings"
under "Selecting Brush Settings options in Effect Controls (PB only)" on page 335. For
information about opening the Vector Paint Preferences dialog box, see "Selecting
viewing options (PB only)" on page 347.
Note: Wacom tablets do not support High Res. Coordinates when Proportional mode is
selected in the Wacom control panel.
If you experience offset coordinates with your pen, try the following:
Check that screen resolution and monitor settings haven't changed.
•
If using a Wacom tablet, make sure that your tablet-mapping aspect isn't set to Propor-
•
tional. Select To Fit mode or One to One mode instead.
Restart your system.
•
If all else fails, turn off Use High Res. Coordinates. (Subpixel accuracy will be lost, but
•
Pressure and Eraser modes will still be available.)
