Look Ma ... No Pixels: Working with Paths and Nodes
|
| |
|
We have succeeded in creating a simple path, and now we
can use the path to create objects. We will fill and stroke the path,
plus move the path on the canvas, and then go on to editing our nodes.

Filled path: The path is deselected, but the filled
object remains on the canvas.

Filling, Stroking and Moving a Path
Select the original path (the first one you named) and right click on
the path on the screen, or use the drop down menu on the side of the
Paths palette to choose Fill Path. The options for path fill are similar
to selection fills. Choose a fill and click OK. In the Paths palette,
click off all paths so none are selected. Surprise ... the filled shape
is still on the canvas. The fill was transferred to the canvas in pixel
form, using the path as a guideline, just as a selection works. Note
in the sample at the left that there are no paths selected, yet the
filled shape remains.
Click on the named path again, and it will appear again on the canvas.
We will use this same path to create a selection, but let's move it
first.

The Path Component tool is used to move a path.

Path is repositioned and stroked using the Airbrush
option.

To move an entire path, select the Path Component tool. Click on the
path, and the nodes along the path will appear. Click and drag the path
to a new location. Note: The named path will change to reflect
the new position when you move the path on the canvas. If you wish to
retain the path with the original position, select Duplicate Path from
the right-click menu, or through the side menu in the Paths palette,
and assign a new name.
Now let's stroke this path. Through the side menu in the Paths palette,
or the right-click menu, select Stroke Path. I have used the Airbrush
option for the stroke shown in the sample at the left. The stroke for
the path will be taken from the settings for the chosen tool. Adjust
the settings for the tool you will use before you create the path stroke.

Copying Paths Between Documents
Now we have objects. We have repeatable objects. Wouldn't it be great
if we could create paths and share them between documents? Ah, but this
is Photoshop and Photoshop is very good at sharing.
Activate the path you wish to copy in the original document. Click
on the path and drag it to the new document canvas. You now have the
path, with the same name as part of the new document. Alternately, you
can click and drag the desired path from the Paths palette listing as
shown at the left. Again, the path will be copied, complete with the
name.
I wanted to slide a few of the neat tricks you can do with paths in
before we started on our node work. Paths are one of the functions in
Photoshop that seem to be shrouded with mystery. Now that you have worked
a little with a simple path, I am guessing that you have relaxed a little.
Now let's start having some fun with changing nodes. The true power
of paths will be in your hands within minutes.

Path selection with the Direct Selection tool shows
hollow nodes.

Nodes selected with the Direct Selection tool are represented
by a solid rectangle at the node.

Selected node is dragged to a new position.

Moving Nodes
We used the Component Selection tool to move our entire path in and
earlier example. This time we are going to change the position of the
nodes in the path, which, of course, changes the shape of the path.
Duplicate your first named path as explained earlier in this article.
Assign a name to the path I used the highly original name "Moving
nodes path." With the new named path active in the paths palette,
activate the Direct Selection Tool. Click anywhere on the canvas to
deselect the path. Click on the path to select. Note how the nodes are
hollow in this selection (see left).
Note: It is good practice when working with nodes to deselect
so that you are sure you are working with a clean selection. It is too
easy to miss that one node is still selected from a previous action.
Drag
the selected node to reposition. You can also move more than one node
at a time. Multiple nodes can be selected by holding the Shift key as
you select nodes, or you can do a marquee select over the desired nodes
as shown at the right. With the nodes selected, simply click and drag
as for the single selected node.

A + appears beside the cursor when a node can be added.

A appears beside the cursor when a node can
be deleted.

Adding or Deleting Nodes
I am going to start by showing you the "proper" way to add
or delete a node, and then will fill you in on one heck of a shortcut.
So why bother with the longer way? You should know what every tool in
your toolbox can do. Since the add and delete function are included
in tools, I think you should at least once use them so they are planted
in your mind.
To
add a node, select the Add Anchor Point tool from the toolbox as shown
to the right. Position your mouse where you would like to place a new
node. A + will appear beside the cursor. Click to add the node.
To
delete a node, select the Delete Anchor Point tool from the toolbox
as shown to the right. Place the cursor over the node you wish to delete,
and a appears beside the cursor. Click to delete the node.
And now, the shortcut. If you select Auto Add/Delete from the toolbar
when you are using the Pen or Freeform Pen Tool, you can add a node
by clicking on any curve segment, or delete a node by clicking on it.
In the sample at the left, note that the Pen tool is active, and there
is a + beside the cursor, indicating that a click will add a node.
This is a powerful shortcut, since it is usually when you are creating
a path that you realize that a node must be added or removed. Switching
tools, or even using a shortcut is much more cumbersome than the intuitive
Auto Add/Delete.
Feeling pretty comfortable with nodes now? If you are not confident
in the methods we have discussed so far, spend a little more time working
with simple lines and nodes. We are ready to move into curves, and creating
more complex paths. With a solid understanding of how nodes work, you
will not be overwhelmed by the options I am about to present.
