- <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.
