Using the paint bucket tool
The paint bucket tool (t) fills adjacent pixels that
are similar in color value to the pixels you click.
The paint bucket options let you specify a mode
and opacity, indicate the color range, or tolerance,
of pixels to be filled, and choose whether to fill
with the foreground color or a pattern. You can
also choose to create smooth edges for the filled
selection.
Note: The paint bucket tool cannot be used with
images in Bitmap or index color mode.
If you’re working on a layer and do not want to
fill transparent areas, make sure that Preserve
Transparency is selected in the Layers palette. See
“Preserving a layer’s transparency” on page 255.
To use the paintbucket tool:
Select the paint bucket tool and then click the part
of the image you want to fill. All adjacent pixels
within the specified tolerance are filled with the
foreground color or pattern.
To choose options for the paint bucket tool:
1 Double-click the paint bucket tool to display its
Options palette.
2 Choose a mode, as explained in “Selecting a
blending mode” on page 208.
3 Drag the slider to set the opacity, as explained in
“Specifying the opacity, pressure, or exposure” on
page 206.
4 Enter the tolerance for the fill.
The tolerance defines how similar in color a
pixel must be to be filled. Values can range from
0 to 255. A low tolerance fills pixels that have
color values very similar to the pixel you click. A
high tolerance fills pixels within a broader range of
colors.
5 To smooth the edges of the filled selection, select
Anti-aliased. See “Using the Anti-aliased option”
on page 154 for more information on anti-aliasing.
6 To fill the selection with the foreground color or
with a pattern, choose an option for Contents. See
“Filling a selection with a pattern” on page 216 for
information on defining and using patterns.
7 To fill pixels using merged data from all visible
layers, select Sample Merged. This option lets you
fill pixels from any visible layer, as long as the
pixels fall within the specified tolerance. Dese-lecting
Sample Merged fills only the pixels on the
active layer.
Using the gradient tool
The gradient tool (G) lets you create a gradual
transition between two or more colors. You can
choose from the existing gradient fills in the Gra-dient
Tool Options palette, or you can create and
edit your own gradient fills. If you don’t select a
specific part of the image to fill, the gradient tool
applies the fill to the entire active layer.
CHAPTER 9 212
Painting
A gradient fill can be applied as either a radial or a
linear fill. A linear gradient fill creates a gradient
from one point to another in a straight line. A
radial fill creates a gradient fill from a center point
outward in all directions.
Linear fill Radial fill
Note: The gradient tool cannot be used with bitmap
or indexed-color images.
To apply a gradient fill:
1 Select the part of the image you want to fill. If
you do not make a selection, the gradient fill is
applied to the entire active layer.
2 Double-click the gradient tool (G) in the
toolbox to display its Options palette.
3 Choose a mode, as explained in “Selecting a
blending mode” on page 208.
4 Drag the slider to set the opacity, as explained in
“Specifying the opacity, pressure, or exposure” on
page 206.
5 If you want to turn off the transparency mask
for the gradient fill, deselect Mask. For more infor-mation,
see “Editing the gradient transparency
mask” on page 214.
6 If you want to create a smoother blend with less
banding, select Dither.
7 For Type, choose one of the following options: Linear to create a linear fill. Radial to create a radial fill.
8 Select a gradient fill from the list.
9 Position the pointer in the image where you
want to set the starting point of the gradient, and
drag to define the length and direction of a linear
fill or to define the radius of a radial fill. To
constrain the line angle to a multiple of 45 ª , hold
down Shift as you drag.
10 Release the mouse button where you want to
set the ending point of the gradient.
Drag to create linear Result
gradient
If you’re creating a linear fill, the portion of the
layer or selection before the starting point is filled
with the starting color; the portion after the end-ing
point is filled with the ending color. If you’re
creating a radial fill, the ending color fills the por-tion
after the ending point.

Creating and editing gradient fills
The Gradient Editor dialog box lets you define the
starting and ending points of a new gradient or
modify an existing gradient. You can also add
intermediate colors to a gradient to create a blend
between more than two colors.
To create or edit a gradient:
1 Double-click the gradient tool (G) to display
its Options palette.
2 Click Edit.
3 Make sure that Color is selected for Adjust, and
do one of the following: To create a new gradient, click New. Enter a
name for the gradient, and click OK. To base your gradient on an existing gradient,
select the existing gradient in the list and click
Duplicate. If you want to name the copied
gradient, hold down Option (Macintosh) or Alt
(Windows) as you click Duplicate. To edit an existing gradient, select it in the list.
4 To define the starting color of the gradient, click
the left square under the gradient bar. The triangle
above the square turns black, indicating that the
starting color is being edited.
5 To choose a color, do one of the following: Click the color swatch below the gradient bar.
Choose a color as described in “Using the Adobe
Photoshop Color Picker” on page 222, and click
OK. Click the foreground selection box to use the
current foreground color. Click the background selection box to use the
current background color. Position the pointer over the gradient bar (the
pointer turns into the eyedropper), and click to
sample a color.
6 To define the ending color, click the right square
under the gradient bar. Then choose a color as
described in the previous step.
7 To adjust the location of the starting point or
ending point, do one of the following: Drag the corresponding
square left or right to
the location you want. Click the corresponding square, and enter a
value for Location. A value of 0% places the point
at the far left end of the gradient bar; a value of
100% places the point at the far right end of the
gradient bar.
