</div>
</div>
</div>
<p>
The most basic, and most commonly used, operation with the
dialog is simply to click on one of the gradients in the
scrollable list, in order to make it GIMP's current gradient,
which will then be used by any operation that involves a
gradient.
</p>
<p>
If you <span class="emphasis"><em>double-click</em></span> on a gradient, you will
be able to edit its name. Note, however, that you are only
allowed to change the names of gradients that you have created
yourself, not the ones that come pre-installed with GIMP. If
you try to rename a pre-installed gradient, you will be able to
edit the name, but as soon as you hit return or click somewhere
else, the name will revert to its original value. It is a
general rule that you cannot alter the resources that GIMP
pre-installs for you: brushes, patterns, gradients, etc; only
ones that you create yourself.
</p>
<p>
The buttons at the bottom of the dialog allow you to operate on
gradients in several ways:
</p>
<div class="variablelist">
<dl>
<dt>
<span class="term">Edit Gradient</span>
</dt>
<dd>
<p>
This button activates the <a href="ch04s12s03.html" title="12.3. Gradient Editor">Gradient
Editor</a>.
</p>
</dd>
<dt>
<span class="term">New Gradient</span>
</dt>
<dd>
<a id="gimp-gradient-new"></a>
<p>
This creates a new gradient, initialized as a simple
grayscale, and activates the Gradient Editor so that you
can alter it. Gradients that you create are automatically
saved in the <tt class="filename">gradients</tt> folder of your
personal GIMP directory, from which they are automatically
loaded when GIMP starts. (You can change this folder, or
add new ones, using the Preferences dialog.)
</p>
</dd>
<dt>
<span class="term">Duplicate Gradient</span>
</dt>
<dd>
<a id="gimp-gradient-duplicate"></a>
<p>
This creates a copy of the currently selected gradient.
You will be able to edit the copy even if you cannot edit
the original.
</p>
</dd>
<dt>
<span class="term">Delete Gradient</span>
</dt>
<dd>
<a id="gimp-gradient-delete"></a>
<p>
This removes all traces of the gradient, if you have
permission to do so. It asks for confirmation before
doing anything.
</p>
</dd>
<dt>
<span class="term">Refresh Gradients</span>
</dt>
<dd>
<a id="gimp-gradient-refresh"></a>
<p>
If you add gradients to your personal
<tt class="filename">gradients</tt> folder by some means
other than this dialog, this button
causes the list to be reloaded, so that the new entries
will be available.
</p>
</dd>
</dl>
</div>
<p>
The functions performed by these buttons can also be accessed
from the dialog pop-up menu, activated by right-clicking
anywhere in the gradient list. The menu also gives you one
additional function:
</p>
<div class="variablelist">
<dl>
<dt>
<span class="term">Save as POV-Ray...</span>
</dt>
<dd>
<a id="gimp-gradient-save-as-pov"></a>
<p>
This allows you to save the gradient in the format used by
the <span class="application">POV-Ray</span> 3D ray-tracing
program.
</p>
</dd>
</dl>
