Using Layers
To stamp layer sets:
Make sure that the layers in the layer set you
1
want to merge are visible. Select the layer set.
Press Ctrl+Alt+E (Windows) or
2
Command+Option+E (Mac OS). A new layer
named after the layer set is created above the layer
set, containing an image that matches all of the
contents of the layer set.
To stamp all visible layers:
Make sure that the layers you want to include
1
are visible.
Select the layer or layer set that you want to
2
contain the new contents, and press
Shift+Ctrl+Alt+E (Windows) or
Shift+Command+Option+E (Mac OS).
The selected layer is stamped with the contents of
all visible layers. If a layer set is selected, a new layer
named after the set is created, the original layer set
is deleted, and all of the layers contained in the set
remain in the Layers palette.
Flattening all layers
In a flattened image, all visible layers are merged
into the background, greatly reducing file size.
Flattening an image discards all hidden layers and
fills the remaining transparent areas with white.
In most cases, you won't want to flatten a file until
you have finished editing individual layers.
Note: Converting an image between some color
modes flattens the file. Be sure to save a copy of your
file that includes all layers if you want to edit the
original image at a later date.
To flatten an image:
Make sure that all the layers you want to keep
1
the content from are visible.
Choose Layer > Flatten Image, or choose
2
Flatten Image from the Layers palette menu.
Saving layered documents
You may want to save two versions of your file—
a flattened version for final use and a second
version with layers intact for future edits.
For more information on saving documents and
determining file formats, see "Saving images" on
page 357.
