Size Controls

The Size brush feature determines how Corel Painter varies the width of the brush stroke. The range from minimum to maximum is determined by Size and Min Size sliders in the Size area of the Stroke Designer page. Some Size controls work in conjunction with Expression settings. For more information about Expression settings, see "Expression Settings" on page 262.

The Brush Dab Preview Window in the Size area of the Stroke Designer page shows how your changes affect the brush dab. Clicking in this preview window lets you toggle between "hard" and "soft" views of the dab. The Preview supports only hard and soft views of dab based brushes.

CJick in the preview window to toggle between "hard" (left) and "soft" (right) views.

In the hard view, concentric circles show the minimum and maximum sizes of a brush. The inner (black) circle shows the minimum dab width. The outer (gray) circle shows the maximum dab width. Remember that some brushes vary the line width based on pressure or stroke speed. The difference between the diameter of the two circles shows the range in which the stroke width can vary.

In the soft view, shading shows the density distribution of the brush tip. The density distribution describes how much of the medium is conveyed by a given point on the brush dab. For example, an individual dab made by an airbrush produces a soft-edged circular mark with minimum density at the outer edge of the dab. Density increases inward to a maximum value at the exact center of the dab. The soft view cannot be used for the Image Hose or rendered dab types.

Brush Tip Profiles

The brush tip, or "profile," shows a cross-section of density distribution across the diameter of the dab. You can think of a brush tip profile as a bell-curve graph representing the density spread across the brush dab.

Different media have different density distributions. Changes in the density distribution produce different marking qualities in a brush stroke. For rendered airbrush dab types, the tip profile controls the concentration of the spray.

Each Corel Painter brush uses one of the following brush tip profiles.

Poin

ted Profile

Provides maximum density at the center, with rapid falloff to the edge.

Med

lum Profile

Has a wide area of greater density at the center, with rapid falloff to the edge.

Line

Ii Profile

Provides maximum density at the center, with even falloff to the edge.

Dull

Profile

Provides maximum density at the center, with high density weighting to the edge.

Watercolor Profile

Provides maximum density at the outer edge in a ringlike fashion, with medium internal density. This tip may be used with the rendered dab types to yield a hollow dab or a spray concentration.

1-Pixel Edge

1-Pixel Edge provides maximum density throughout, with rapid falloff at the edge, producing a 1-pixel, anti-aliased edge.

Artists' Oils Brush Tip Profiles

There are six brush tips designed specifically for Artists' Oil brushes. You can also use any brush tip, listed in the table above, with Artists' Oil brushes.

Soft

Round

Provides maximum density throughout, with rapid falloff at the edge.

Poin *

ted Rake

Provides a range of bristle lengths, with bristles longer in the center and tapering in length toward the edge.

Flat

Rake

Provides a range of bristle lengths and maximum density throughout, producing pronounced, even bristling.

Flat

Designed for Artists' Oil palette knives, it provides maximum density throughout, with rapid falloff at the edge.

Chis

A

Designed for Artists' Oil palette knives, its maximum density is off-center, with uneven falloff.

Wedge

Designed for Artists' Oil palette knives, it provides maximum density at one edge, with consistent falloff to the other edge.

To choose a brush tip

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

2 Click the brush tip profile that you want to use.

Stroke Size

The Size slider controls the width of the brush and the brush stroke. As Size changes, you may need to adjust the Spacing controls for brushes that use nonrendered or dab-based dab types to prevent gaps from appearing in the stroke.

In your studio, you expect the pressure you exert on a brush or drawing tool to make a difference in the width of the resulting brush stroke. The Min Size control allows you to create a brush stroke that is amazingly realistic. You can set up a brush that responds to the elegance of subtle hand movements. As stylus pressure eases, brush strokes taper. As pressure increases, brush strokes widen, just as they would with a real brush.

Min Size represents the smallest stroke size for the selected brush and is expressed as a percentage of the Size setting. Knowing that Size sets the largest stroke size and that Min Size sets the smallest stroke size (in relationship to the Size setting), you can easily control the overall variation in stroke size.

The minimum and maximum sizes of a stroke can be linked to stylus settings, such as pressure or velocity. The small black circle shows the minimum stroke size, and the gray circle shows the maximum stroke size.

The Size Step slider controls the transition between narrow and wide sections of a stroke. Moving the slider to the right makes the transition appear more abrupt. Moving it to the left makes the transition smoother. Size step is applicable only to dab-based brushes.

The Size Step slider controls the transition between the narrow and wide sections of a stroke. Settings shown are 1% (top) and 100% (bottom).

For brushes that use rendered dab types, the Feature slider determines the size of the dabs of paint applied.

To set brush size in the Stroke Designer

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

2 Move the Size slider to the right to make the brush larger, or to the left to make it smaller.

You don't need to open the Size area of the Stroke Designer page to adjust the size of a brush. You can type a value in the Size box on the property bar, or you can adjust the slider on the property bar. For more information on the property bar, see "Property Bar Basics" in the Help.

You can also press the square brackets, ( [ or ] ), to decrease and increase the brush size according to the value specified in General Preferences. For more information, see "General Preferences" on page 32.

To use the brush sizing shortcut

1 Hold down Command + Option + Shift (Mac OS) or Ctrl + Alt + Shift (Windows), and drag in the image window.

A circle that represents the brush diameter appears beneath the cursor.

2 When you've dragged the circle to the size you want, release the mouse button.

The brush sizing shortcut lets you use keyboard commands to adjust the brush size in the document window.

To set minimum stroke size

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

2 Move the Min Size slider to the right to increase the minimum brush size. Move it to the left to decrease the minimum brush size.

To set stroke transition

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

2 Move the Size Step slider to the right to increase the transition between brush sizes. Move it to the left to make the transitions smaller.
