paper over an image and drawing lines and curves.
When you save a path in the Paths palette, you save
the piece of tracing paper with all of its contents.
A path consists of one or more segments. Anchor
points define where the path segments begin and
end. A curved path is defined also by direction
lines, which determine the shape and direction of
each curved segment. A closed path has no begin-ning
or end; for example, a circle is a closed path.
An open path has distinct endpoints; a wavy curve
is an example of an open path.
Closed and open paths
A path in the Paths palette can consist of one or
more subpaths. A subpath consists of a series of
connected path segments; different subpaths are
disconnected from each other. For example, you
can first draw a line, then draw a curve that is dis-connected
from the line, and save both subpaths as
a single path in the Paths palette.
You can use paths to define shapes and areas for
painting, and to define smoothly shaped selec-tions.
Because paths always consist of smooth,
anti-aliased outlines, they provide an excellent
alternative to using the lasso tool, which tends to
produce irregularly shaped selections. Paths are
useful for long-term storage of simple masks,
because paths are small, compact, and take up
much less disk space than do pixel selections. You
can also use paths to clip sections of your image for
export to an illustration or page-layout applica-tion
(see “Using clipping paths” on page 322).

Using the Paths palette
The Paths palette lists the paths you have created.
A thumbnail of the path contents appears to the
left of the path name. Use the scroll bars or resize
the palette to see additional paths.
To display the Paths palette:

Selecting
Selecting and displaying paths
The Paths palette lets you select, deselect, show, or
hide entire paths in your image.
To select a path:
Click the path in the Paths palette. The name of the
path is highlighted in the palette, and the selected
path appears in the image. You can select only one
path at a time.
To deselect a path:
Click outside the path in the Paths palette.
To hide a path:
Do one of the following: In the Paths palette, select the path and choose
Turn Off Path from the palette menu. Choose View > Hide Path.
To show a path:
Do one of the following: In the Paths palette, select the path. Choose View > Show Path.
To toggle between hiding and showing a
path, Shift-click the path in the Paths palette.
Hiding and resizing path thumbnails
You can change the size of or turn off the thumb-nail
for each path. Increasing the thumbnail size
provides more detail for each path shape. Decreas-ing
the size or turning off the thumbnail lets you
view more paths in the Paths palette at one time
and can improve Adobe Photoshop’s perfor-mance.
To change the size of a path thumbnail:
1 Choose Palette Options from the Paths palette
menu.
2 Select a size, or select None to turn off the
display of thumbnails.
Creating paths
You create a path using one of two methods: you
can create a new path in the Paths palette and then
begin to draw with the pen tool, or you can draw
with the pen tool first and then save the path in the
Paths palette. If you create a path in the Paths pal-ette
first, the path you draw is saved automatically.
If you begin drawing first, the path you draw
appears in the Paths palette as a temporary work
path. You must save a work path to preserve its
contents during a work session.

Creating new paths
When you create a new path, it appears at the bot-tom
of the paths list in the Paths palette. The lines
and curves you draw with the pen tool are added
to the contents of this new path.
To create a new path without naming it:
Click the New Path button at the bottom of the
Paths palette.
To create a new path:
1 Do one of the following: Make sure no work path is selected, and choose
New Path from the Paths palette menu. Option-click (Macintosh) or Alt-click
(Windows) the New Path button (O) at the
bottom of the Paths palette.
2 Enter a name for the path in the New Path
dialog box, and click OK.
Previewing path segments
The Rubber Band option lets you preview path
segments before you draw them. As you move the
pointer in the image, Photoshop interactively dis-plays
the segment that will be created. The path
segment does not become permanent until you
press the mouse button.
To preview path segments as you draw:
1 Double-click the pen tool to display its Options
palette.
2 Select Rubber Band.
Drawing straight line paths
You draw a straight line path by clicking to
define the endpoints, or anchor points, of the
path segments.
To draw straight line paths:
1 Select the pen tool.
2 Position the pointer where you want the straight
line to begin, and click to define the first anchor
point. The anchor point remains selected (solid)
until you define the next point.
As you begin drawing with the pen tool, Work Path
appears at the bottom of the paths list if you have
not already created a new path.
3 Click where you want the first segment of the
straight line path to end. Hold down Shift as you
click to constrain the angle of the segment to a
multiple of 45 ° .
The second anchor point is now selected, and the
first anchor point changes to a hollow square, indi-cating
that it is no longer selected.
