Preserving Layer
Transparency
Areas of a layer that don’t contain
imagery are transparent. You can
preserve the transparent areas of a
layer with the Preserve Transparency
check box on the Layers palette. This
option affects what areas of a layer you
can create imagery on. It also affects
the results of erasing or deleting
imagery on a layer.
By default, the Preserve Transparency
check box is disabled, which lets you
paint anywhere on the layer. When
Preserve Transparency is enabled, the
transparent areas are preserved, and
you are confined to painting on areas
of the layer that already contain
imagery.
The results of painting on a layer with the
Preserve Transparency option disabled and
enabled
A good way to think about the
Preserve Transparency option is in
terms of a layer mask. As described in
“Working with Layer Masks” on
page 255, a layer mask defines the
visible areas of a layer.
Preserve Transparency provides a
powerful selective editing capability
for altering the strokes you've already
applied and creating interesting
effects. For example, enable Preserve
Transparency to fill a set of hand-
drawn letters with a pattern, a color
gradient, or other brush strokes.
Preserve Transparency also affects the
results of cutting or erasing on a layer.
• When Preserve Transparency is
disabled, erasing or deleting
imagery restores transparency to
the area—revealing the underlying
image.
• When Preserve Transparency is
enabled, erasing or deleting
imagery reveals the document’s
paper color. In effect, erasing or
deleting with Preserve
Transparency enabled is the same
as painting or filling with the
document’s paper color.
