Adjusting and Editing Brushes
The Brush editor makes it easy to create brush variants. You can adjust brushes in many different ways. In fact, the default brush variants in the Brush selector on the Brush tool property bar are built with the same set of controls used to build every other variant. They have just been adjusted until the results emulate a real-life drawing tool.
Although these default brushes do excellent work, you will probably want to adapt them to your particular needs, refining them to fit your own style of working. You can change their Size, Shape, Angle, Spacing , and much more.
Changes you make to brush variants, including basic controls like Size and Opacity, are saved until the Restore Default Variant command is selected.
When Artweaver starts, it references the folder Brushes in the user folder. Any customizations made to brushes are saved to this folder and are referenced by Artweaver in place of the original default brushes and settings stored in the application folder. |

Methods and Categories
The brush method defines the most basic level of brush behavior and is the foundation on which all other brush variables build.
Because the method sets a brush variants most basic behavior, you can alter a variants behavior by changing its method.
Each method can have several variations, called method categories. These categories further refine the brush behavior. The following terms are used in describing most method categories:
- Soft methods produce strokes with feathered edges
- Flat methods produce hard, aliased strokes with pixelated edges
- Hard methods produce smooth strokes
- Grainy methods produce brush strokes that react to paper texture
Combining a method with a method category results in a specific brush style that you can assign to a given brush.
To choose a method and category
- In the Tools palette, click the Brush tool
- On the property bar, click the Brush settings button . The Brush editor is expanded
- Click the tab General on the Brush editor
- Choose a method from the Method box
- Choose a category from the Category box

Opacity and Grain
The Opacity slider determines how the density of the media should be applied. It sets the maximum opacity of the selected brush. You can use the Expressions settings to link Opacity to pen or mouse data.
The Grain slider determines the maximum amount of paper texture that should reveal in a brush stroke. You can use the Expressions settings to link Grain to pen or mouse data. You can also use the paper's brightness and contrast settings to control Grain interaction.
To set brush opacity
- In the Tools palette, click the Brush tool
- On the property bar, click the Brush settings button . The Brush editor is expanded
- Click the tab General on the Brush editor
- Move the Opacity slider to the left to reduce opacity, or to the right to increase opacity

- Move the Grain slider to the left to increase the penetration into the paper texture. Move it to the right to reduce the penetration
Adjusting Paper Texture behavior
When you use a brush that interacts with paper texture, the results appear with each stroke. If you have a stylus and tablet, you can adjust paper texture by changing the stroke of the stylus on a pressure-sensitive tablet. In most cases, a light stroke colors only the peaks and ridges of the texture. A heavy stroke fills color deep into the pockets and valleys. You can also affect the brush interaction with paper texture by changing the brush grain settings.
By default, paper texture is fixed, which means that the texture is in the same position each time you apply a brushstroke. You can change this setting if you want texture to be applied randomly.
This feature is only available in Plus version. |
To randomize paper texture
- In the Tools palette, click the Brush tool
- On the property bar, click the Brush settings button . The Brush editor is expanded
- Click the tab Grain on the Brush editor
- Enable the Randomize texture check box
Brush Tip Profiles
The brush tip, or profile, shows a cross-section of density distribution across the diameter of the dab.
Different media have different density distributions. Changes in the density distribution produce different marking qualities in a brush stroke.
The following brush tip profiles are available:
Medium Profile |
Has a wide area of greater density at the center, with rapid falloff to the edge. |
Dull Profile |
Provides maximum density at the center, with high density weighting to the edge. |
Linear Profile |
Provides maximum density at the center, with even falloff to the edge. |
Watercolor Profile |
Provides maximum density at the outer edge in a ringlike fashion, with medium internal density. |
1-Pixel Edge |
1-Pixel Edge provides maximum density throughout, with rapid falloff at the edge, producing a 1-pixel, anti-aliased edge. |
Soft profile |
Provides maximum density at the center, with soft falloff to the edge. |
Anti-aliasing
Artweaver can draw dabs in an anti-aliased fashion. This anti-aliasing gives brushes a smooth edge, as opposed to the jagged edges without anti-aliasing.
This feature is only available in Plus version. |
To enable drawing dabs in an anti-aliased fashion
- In the Tools palette, click the Brush tool
- On the property bar, click the Brush settings button . The Brush editor is expanded
- Click the tab General on the Brush editor
- Enable the Anti-aliased check box
Spacing Controls
When a brush is used, the stroke consists of 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. Each dot or dash represents one brush dab.
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.
When the Continuous Time Deposition check box is disabled, you must move the brush (even just slightly) to cause color to be deposited. |
To set brush spacing
- In the Tools palette, click the Brush tool
- On the property bar, click the Brush settings button . The Brush editor is expanded
- Click the tab Spacing on the Brush editor

To set Continuous Time Deposition
- In the Tools palette, click the Brush tool
- On the property bar, click the Brush settings button . The Brush editor is expanded
- Click the tab Spacing on the Brush editor
- Enable the Continuous Time Deposition check box
Stroke Controls
The Smoothing slider allows you to soften the appearance of brushstrokes by adding additional points into dab paths which are used to replot brushstrokes.
You can also apply a merge mode to a brush variant to control how brushstrokes interact with the underlying colors within the currently selected layer or the canvas. This technique allows you to produce similar results to applying blend method to layers. In addition, it allows you to control where the effect is applied.
This feature is only available in Plus version. |
