The pattern you defined is repeated as tiles within
the selection.
Using PostScript patterns to fill a
selection
The Adobe Photoshop software contains a folder
of PostScript patterns that you can use to fill selec-tions.
Each file in this folder contains a single pat-tern
in the Adobe Illustrator format; you can scale
and render these patterns at any resolution.
To use a pattern from the PostScript patterns folder:
1 Choose File > Open.
2 Select the pattern file you want to use, and click
Open.
3 Select the rasterizing options you want to use.
See“Importing Adobe Illustrator files” on page 54
for information on these options.
4 Click OK.
5 Make a rectangular selection around the
pattern, or choose Select > All.
6 Choose Edit > Define Pattern. The pattern is
defined as an Adobe Photoshop pattern.
7 Open an image and select the part you want to
fill.
8 Choose Edit > Fill.
9 For Use, select Pattern and click OK.
Stroking a selection
The Stroke command uses the foreground color to
paint a border around a selection or around the
edge of a layer. As with the Fill command, you can
specify the opacity and blending mode of the fill.
To stroke a selection or layer:
1 Select the area or layer you want to stroke.
2 Choose Edit > Stroke.
3 Specify the width and location of the border.
Values for the width can range from 1 to 16 pixels.
4 Set the opacity, as explained in “Specifying the
opacity, pressure, or exposure” on page 206.
5 Choose a mode, as explained in “Selecting a
blending mode” on page 208.
6 If you’re working in a layer and want to stroke
only areas containing pixel values, select the
Preserve Transparency option. See “Preserving a
layer’s transparency” on page 255 for more infor-mation.
7 Click OK to stroke the selection or layer.
Selected area Selection stroked: 10 pixels

Painting
Using the eyedropper tool
The eyedropper tool (D) lets you sample color
from an area of an image to designate a new fore-ground
or background color. You can sample from
the active image or from another image. (When
you’re using the eyedropper, you can click in a
background window without making it the active
window.)
You can also specify the sample area that the eye-dropper
tool reads. For example, you can set the
eyedropper to sample the color values of a 3-by-3-
screen-pixel area under the pointer. Modifying the
sample size of the eyedropper affects the color
readouts displayed in the Info Palette.
To select the foreground or background color using
the eyedropper:
1 Click the eyedropper tool (D).
2 Do one of the following: To select a new foreground color from an image,
click the color you want. To select a new background color from an
image, Option-click (Macintosh) or Alt-click
(Windows) the color you want.
If you drag the eyedropper tool, the foreground
color selection box changes dynamically as you
drag. Option-drag (Macintosh) or Alt-drag (Win-
dows) to activate the background color selection
box. Release the mouse button to pick the new
color.
To use the eyedropper tool temporarily
while using any painting tool, hold down
Option (Macintosh) or Alt (Windows).
To change the sample size of the eyedropper:
1 Double-click the eyedropper tool to display the
Eyedropper Options palette.
2 Choose one of the following options from the
Sample Size menu: Point Sample to read the precise value of the
pixel you click. 3 by 3 Average or 5 by 5 Average to read the
average value of the specified number of screen
pixels within the area you click.
Using the Color palette
The Color palette displays the color values for the
current foreground and background colors. Using
the sliders in the Color palette, you can edit the
foreground and background colors according to
several different color models.

To edit the foreground or background color using
the Color palette:
1 Choose Window > Show Color.
2 From the Color palette menu, choose the color
model you want to use for color readout values.
See “Setting color readout values” on page 220 for
a discussion of these models.
3 To edit the foreground or background color,
make sure that its color selection box is active
(outlined in black). To make the foreground or
background color selection box active, click
the box.
4 To specify a new color, do one of the following: Drag the color sliders.
By default, the slider colors change as you drag. If
you want to turn off this preview feature to
improve performance, choose File > Preferences >
General and deselect Dynamic Color Sliders. Enter values next to the color sliders. Click the color selection box, choose a color as
described in “Using the Adobe Photoshop Color
Picker” on page 222, and click OK.
Note: An exclamation point inside a triangle in the
Colors palette indicates that you have chosen an out-of-
gamut color, that is, a color that cannot be printed
using CMYK inks. The closest CMYK equivalent
appears next to the triangle. Click CMYK equivalent
to substitute it for the out-of-gamut color. See “Iden-tifying
out-of-gamut colors” on page 111 for more
information.
Choosing a color from the color bar
The color bar along the bottom of the Color pal-ette
lets you quickly choose a background or fore-ground
color from a specified spectrum of colors.
To sample colors from the color bar:
1 To edit the foreground or background color,
make sure that its color selection box is active
(outlined in black). To make the foreground or
background color selection box active, click
the box.
2 Position the pointer over the color bar (the
pointer turns into the eyedropper), and click to
sample a color.
To change the display of the color bar:
1 Choose Color Bar from the Color palette menu.
2 For Style, choose a model and then click OK.
The Current Colors option displays a transition
from the current foreground color to the current
background color.
