Spacing Controls

When a brush stroke uses a dab-based dab type, Corel Painter creates the stroke with a series of dabs. By adjusting the spacing between those dabs, you can control the continuity of the brush stroke.

The Spacing slider controls the distance between brush dabs in a stroke. The Min Spacing slider specifies the minimum number of pixels between dabs. If you don't want a continuous stroke, you can adjust the Min Spacing to create a dotted or dashed line. Each dot or dash represents one brush dab.

The Min Spacing slider controls the minimum number of pixels between dabs. Settings shown are 2.0 (top) and 10.5 (bottom).

Damping is used to smooth otherwise jagged brush strokes for brushes using rendered dab types. Higher values make the stroke smoother. (Damping suspends a stroke in a mathematical spring area by using calculations to even out edges and reduce jaggedness.)

High values of Damping round out corners of a stroke. A value of 50% works best. Higher values might be necessary for jittery input devices such as a mouse.

Continuous Time Deposition controls whether you must move a brush before a medium is applied. With Continuous Time Deposition enabled, the medium begins flowing at the first touch.

Brushes that use rendered dab types take full advantage of this setting, causing the medium to pool realistically when the stroke is slowed or paused. Brushes that use dab-based dab types require a full pause in the stroke before the medium begins to pool. You use Continuous Time Deposition mostly with airbrush tools.

With Continuous Time Deposition disabled, you must move a brush before the medium flows.

Cubic Interpolation smooths jagged brush strokes by adding points to dab paths, primarily for brushes that use dab-based dab types. Unlike Damping, which uses mathematical calculations to smooth jagged edges, Cubic Interpolation inserts additional points into dab paths, which are used to replot brush strokes.

Cubic Interpolation is best for dab-based dab types, while Damping is best for rendered dab types.

To set spacing between brush dabs

1 On the Stroke Designer page of the Brush Creator, click Spacing.

2 Do one of the following:

• To increase the spacing between dabs, move the Spacing slider to the right bringing it closer to the size of the dab itself.

When the Spacing slider is at 100%, the size of the dab equals the spacing. For example, a dab that is 10 pixels across is repeated every 10 pixels.

• To decrease the distance between dabs, move the Spacing slider to the left until the dabs begin to overlap.

Overlapping increases the density of the stroke and makes it look more continuous.

To set minimum dab spacing

1 On the Stroke Designer page of the Brush Creator, click Spacing.

2 Move the Min Spacing slider to the right to increase the minimum spacing between dabs. Move it to the left to decrease the minimum spacing between dabs.

To set smooth rendered dab strokes

1 On the Stroke Designer page of the Brush Creator, click Spacing.

2 Move the Damping slider to the right to even out jagged strokes. Move it to the left to allow for more ragged transitions between points on the stroke.

To set Continuous Time Deposition

1 On the Stroke Designer page of the Brush Creator, click Spacing.

2 Enable the Continuous Time Deposition check box.

To set smooth strokes by adding path points

1 On the Stroke Designer page of the Brush Creator, click Spacing.

2 Move the Points slider to the right to add points and even out jagged strokes. Move it to the left to decrease the number of additional points.
