Viewing layers
You use the Layers palette to show, hide, and pre-view
layers. You can also control how transparent
areas in a layer appear in your image.
Map layer and background hidden
Showing and hiding layers
You can make layers temporarily invisible to speed
performance as you edit or print other parts of the
image. Only visible layers are printed. When a
layer is visible, an eye icon appears in the leftmost
column of the Layers palette for that layer.
To show or hide a layer:
Do one of the following: In the Layers palette, click the eye icon next to a
layer to hide that layer. Click in the column again
to redisplay the layer. Drag through the eye column to show or hide
multiple layers. Option-click (Macintosh) or Alt-click
(Windows) the eye icon for a layer to display just
that layer. Option/Alt-click in the eye column
again to redisplay all the layers.
Note: You can have an active layer that is not visible;
in most cases, however, you will want the active layer
to be visible.
Hiding and resizing layer thumbnails
You can change the size or turn off the display of
thumbnails in the Layers palette. Thumbnails are
the most convenient way of monitoring layer con-tents,
but turning off thumbnails can improve per-formance
and save disk space. Using smaller
249
thumbnails reduces the space required by the Lay-ers
palette and can be helpful when you’re working
on a smaller monitor.
To change the display of layer thumbnails:
1 Choose Palette Options from the Layers palette
menu.
2 Click a size or click None to turn off the thumb-nails,
and then click OK.
Setting transparency preferences
A layer is transparent until you add pixels to it. By
default, the transparent areas of a document
appear as a checkerboard pattern. You can change
the appearance of this pattern.
To change the transparency settings:
1 Choose File > Preferences > Transparency &
Gamut.
2 For Grid Size, select a new size for the pattern. If
you choose None, transparent areas in the layer
appear white.
3 For Grid Colors, select one of the following
options: Light, Medium, or Dark to specify a gray
pattern. Any other color from the list to display the
checkerboard in that color. Custom to choose a color that does not appear in
the list.
4 If you chose Custom, click either of the color
selection boxes (with the current pattern colors) to
choose a custom color from the Color Picker.
5 Click OK.
Moving and copying layers
You can move, copy, and change the stacking order
of layers.
Changing the order of layers
You can use the Layer menu or the Layers palette
to change the stacking order of layers in an image.
To change the order of a single layer:
1 In the Layers palette, select the layer that you
want to move.
2 Choose Layer > Arrange, and choose one of the
following options from the submenu: Bring to Front to make the layer the topmost
layer. Bring Forward to move the layer one level up in
the stacking order. Send Backward to move the layer one level down
in the stacking order. Send to Back to make the layer the bottommost
layer in the image (except for the background).

Note: By default, the background cannot be moved
and is always at the bottom of the layer list. To move
the background to a different location, first convert
the background into a layer by double-clicking the
background name, typing a new name, and clicking
OK.
Moving layers
You can move the contents of a layer within its
image window. You can also link multiple layers
and move their contents together.
To move a layer in an image:
1 In the Layers palette, select the layer that you
want to move to make it the active layer.
2 Select the move tool. To activate the move tool
when any other tool is selected, hold down
Command (Macintosh) or Ctrl (Windows).
3 Drag anywhere in the image to move the
selected layer into the desired position. To
constrain the direction of movement to a multiple
of 45 ª , hold down Shift as you drag.
