</div>
</div>
</div>
<p>
Each path belongs to one image: paths are components of images
just like layers. The Paths dialog shows you a list of all
paths belonging to the currently active image: switching images
causes the dialog to show a different list of paths. If the
Paths dialog is embedded in a "Layers, Channels, and Paths"
dock, you can see the name of the active image in the Image Menu
at the top of the dock. (Otherwise, you can add an Image Menu
to the dock by choosing "Show Image Menu" from the Tab menu.)
</p>
<p>
If you are familiar with the Layers dialog, you have a head
start, because the Paths dialog is in several ways similar. It
shows a list of all paths that exist in the image, with four
items for each path:
</p>
<div class="variablelist">
<dl>
<dt>
<span class="term">Path visibility</span>
</dt>
<dd>
<p>
<span class="guiicon">
<span class="inlinemediaobject"><img src="../images/dialogs/dialogs-icon-eye.png" /></span>
</span>
</p>
<p>
An "open eye" icon if the path is visible, or a blank space if
it is not. "Visible" means that a trace of the path is drawn
on the image display. The path is not actually shown in the
image pixel data unless it has been stroked or otherwise
rendered. Clicking in the eye-symbol-space toggles the
visibility of the path.
</p>
</dd>
<dt>
<span class="term">chain paths</span>
</dt>
<dd>
<p>
<span class="guiicon">
<span class="inlinemediaobject"><img src="../images/dialogs/dialogs-icon-vchain.png" /></span>
</span>
</p>
<p>
A "chain" symbol is shown to the right of the
eye-symbol-space if the path is transform-locked, or a blank
space if it is not. "Transform-locked" means that it forms
part of a set of elements (layers, channels, etc) that are
all affected in the same way by transformations (scaling,
rotation, etc) applied to any one of them. Clicking in the
chain-symbol-space toggles the transform-lock status of the
path.
</p>
</dd>
<dt>
<span class="term">preview image</span>
</dt>
<dd>
<p>
A small preview-icon showing a sketch of the path. If you
click on the icon and drag it into an image, this will
create a copy of the path in that image.
</p>
</dd>
<dt>
<span class="term">path name</span>
</dt>
<dd>
<p>
<span class="guiicon">
<span class="inlinemediaobject"><img src="../images/dialogs/dialogs-layer-rename.png" /></span>
</span>
</p>
<p>
The name of the path, which must be unique within the
image. Double-clicking on the name will allow you to edit
it. If the name you create already exists, a number will be
appended (e.g., "#1") to make it unique.
</p>
</dd>
</dl>
</div>
<p>
If the list is non-empty, at any given moment one of the
members is the image's <span class="emphasis"><em>active path</em></span>, which
will be the subject of any operations you perform using the
dialog menu or the buttons at the bottom: the active path is
shown highlighted in the list. Clicking on any of the entries
will make it the active path.
</p>
<p>
Right-clicking on any entry in the list brings up the <a href="ch04s04s04.html" title="4.4. Paths Menu">Paths Menu</a>. You can also
access the Paths Menu from the dialog Tab menu.
</p>
