The roughening effect lets you apply a
jagged or spiked edge to objects, including lines, curves, and text. You can
control the size, angle, direction, and number of the indentations whether you
activate the graphics tablet stylus or apply settings to a mouse.
The roughening effect is determined either by movements of a graphics tablet
stylus, by fixed settings, or by automatically applying perpendicular spikes to
the line. Tilting the stylus toward and away from the tablet’s surface increases
and decreases the size of the spikes. If you are using a mouse, you can specify
the tilt angle from 1 - 90°. You can determine the direction of the spikes by
changing the angle of rotation (or bearing) of the stylus as you apply the
roughening effect to an object. When you are using a mouse, you can set the
bearing angle from 0 - 359°. You can also increase or decrease the number of
spikes that are applied as you drag.
The roughening effect also responds to the pressure of the stylus on the tablet.
The more pressure you apply, the more spikes are created in the roughened area.
If you are using a mouse, you can specify values to simulate the stylus
You can also change the brush nib size
Roughening allows you to apply jags or spikes to part of an outline or path.
