<span class="term">Gradient</span>
</dt>
<dd>
<p>
The airbrush has a gradient property, which can be controlled
from this drop-down list, which is identical to the standard

using the checkbox to the right of the gradient selector.

of the set distance.
</p>
</dd>
<dt>
<span class="term">Use Color from Gradient</span>

<dd>
<p>
With the checkbox activated, instead of using the
foreground or background
color drawing, the gradient colors are used. The gradient pattern
may have repeat patterns, with selected cycle lengths.
