Smudging and smearing objects

Smudging and smearing let you shape an object by pulling extensions or making indents along its outline. With smudging, the extensions and indents resemble streaks that vary little in width as you drag with the Smudge brush tool. With smearing, the extensions and indents have a more fluid shape that decreases in width as you drag with the Smear tool.

Smudging objects

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 use a pen tablet or a mouse.

The smudging effect responds to both the angle of rotation — or bearing — and the tilt angle of the stylus (also known as a pressure-sensitive pen). 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 to 359° changes the angle of the brushstroke. As you decrease the tilt angle from 90° to 15°, you change the smudging shape by flattening the brush tip.

Smudging can respond to the pressure of a stylus on a pen 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 pen tablet. Negative values to -10 create a narrowing distortion, 0 maintains an even stroke width, and positive values to 10 create an expanding distortion.

Whether you are using a pen tablet 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.

Smearing objects

To control the smearing effect, you can set the size of the brush nib and the amount of effect to apply, and you can use the pressure of your digital pen. You can use smooth curves or curves with sharp corners when smearing objects.

Smearing an object

To smudge an object

1 .	Select a curve object using the Pick tool .

2 .	Click the Shape tools button in the toolbox, and click the Smudge brush tool .

You can also
Change the size of the brush nib	Type a value in the Nib size box on the property bar.
Change the size of the brush nib when using a pen tablet	Click the Pen pressure button on the property bar, and apply pressure to the pen.
Widen or narrow the smudging	Type a value between -10 and 10 in the Dryout box on the property bar.
Specify the shape of the smudging	Type a value between 15 and 90 in the Tilt box on the property bar.
Change the shape of the smudging when using a pen tablet	Click the Pen tilt button on the property bar.
Specify the angle of the nib shape for smudging	Type a value between 0 and 359 in the Bearing box on the property bar.
Change the angle of the nib shape for smudging when using a pen tablet	Click the Pen bearing button on the property bar.
Smudge the inside of an object	Click the outside of an object and drag inwards.
Smudge the outside of an object	Click the inside of an object an drag outwards.

You cannot apply smudging to Internet or embedded objects, linked images, grids, masks, mesh-filled objects, or objects with blend and contour effects.

To see the minimum and maximum values for the smudging controls, right-click the control on the property bar and click Settings.

To smear an object

1 .	Select a curve object using Pick tool .

2 .	Click the Shape tools button in the toolbox, and click the Smear tool .

You can also
Change the radius of the brush nib	Type a value in the Nib radius box on the property bar.
Set the amount of smearing	Type a value in the Pressure box.
Use the pressure of a digital pen to control the amount of smearing	Click the Pen pressure button on the property bar.
Use smooth curves when smearing	Click the Smooth smear button .
Use curves with sharp corners when smearing	Click the Pointy smear button .

The difference between a smooth smear and pointy smear is noticeable only with higher Pressure values.
