Smudging lets you distort an object by dragging its outline. When applying
smudging to an object, you can control the extent and shape of the distortion
whether you activate the controls for the graphics tablet stylus or use the
settings that apply to a mouse.
The smudging effect responds to both the angle of rotation — or bearing — and
the tilt angle of a graphics tablet stylus. Rotating the stylus changes the
angle of the smudging effect and tilting the stylus flattens the brush tip and
changes the shape of the smudging. If you are using a mouse, you can simulate
the bearing and tilt of the stylus by specifying values. Increasing the bearing
angle from 0 - 359° changes the angle of the brush stroke. As you decrease the
tilt angle from 90° - 1°, you change the smudging shape by flattening the brush
Smudging can respond to the pressure of a stylus on a tablet where the smudging
widens with more pressure and narrows with less. If you are using a mouse or
want to override stylus pressure, you can enter real values to simulate the
pressure of a stylus on a graphics tablet. Negative values to -10 create a
narrowing distortion, 0 maintains an even stroke width, and positive values to
10 create an expanding distortion.
Objects placed in the foreground and background have been shaped by outside
smudging (sun’s rays and blades of grass) and inside smudging (clouds).
Whether you are using a stylus or a mouse, you must specify the nib size. The
nib size determines the width of the smudging applied to an object.
You can apply the smudging effect to the inside and outside of an object.
