3. Basics of PhotoLine

## 3.5 The Brush Editor

Brushes are edited with the brush editor. The brush editor appears by double clicking a brush field or by choosing Edit... in the context menu.

If the active brush is geometric, a combo box contains the kind of the brush: rectangular or round.

In the left top the result of the current settings is shown.

Outer Radius defines the size of the brush.

If Inner Radius is smaller than the outer radius, PhotoLine creates a gradient in between. The curve field in the left bottom can modify this gradient.

Roundness reduces the vertical size of the brush. A circle becomes an oval.

Angle rotates the brush. With circular brushes this setting has only a visible effect, if the roundness of the brush has been changed.

Steps specifies the distance between two brush points while drawing. The value is given in percent of the brush size. If the value is small (e.g. 10), the result is a continuous line:

If the value is large (e.g. 120), the result is a dotted line:

Values too small result in slow drawing.

Jitter allows to randomly modify the behaviour of the brush:

- Position: The brush position differs from the mouse position.
- Size: The brush size is modified.
- Angle: The rotation angle of the brush is modified. The entered value is used for both sides, so a value of 45° modifies the angle from -45° to 45°.
- Color: The color of the tool is modified. If the foreground color is a "normal" color, a random color inbetween the foreground and background color will be created. If the foreground color is a blend or a pattern, the used color will be read directly from the foreground color.
This setting has only an effect, if the active tool uses the foreground color.
