Color Expression Controls
The color expression controls in the Brush Creator are identical to those on the
Color Expression palette. For more information, see “Setting Color Expression” on
page 103.
Expression Settings
Corel Painter lets you control brush effects along the stroke based on a number of
real-time input factors. For example, many brushes vary their Opacity or Size in
response to changes in stylus pressure. These responses reflect their default settings.
You can use the Expression settings on the Stroke Designer page to vary these effects
in response to other factors, such as stroke direction or velocity.
Expression settings are linked to the individual controls on the Stroke Designer page:
General, Size, Angle, Well, Random, Impasto, Airbrush, and Liquid Ink.
The Direction slider below the Expression pop-up menu adjusts the angle value of the
Direction controller. When the Expression pop-up menu is set to Direction, it specifies
the angle at which a brush stroke narrows or widens, which is particularly useful for
calligraphic effects.
To choose an Expression setting
1 On the Stroke Designer page of the Brush Creator, click a control that contains
Expression settings.
2 Choose one of the following options from the Expression pop-up menu:
• None applies no adjustment to the brush feature.
• Velocity adjusts the brush feature based on the dragging speed. Dragging
quickly minimizes the setting; dragging more slowly increases it.
• Direction adjusts the selected brush feature based on the direction of the stroke.
• Pressure adjusts the brush feature based on stylus pressure. Greater pressure
increases the setting for that brush feature.
• Wheel adjusts the brush feature based on the wheel setting on an airbrush
stylus, specifically the Intuos Airbrush stylus. The maximum value is set when
the wheel is pushed all the way forward. The minimum is set when the wheel is
pushed all the way back.
• Tilt adjusts the brush feature based on the angle of the stylus from the tablet.
For example, when the stylus is perpendicular to the tablet, Tilt is set at zero.
