CHAPTER 6

Using Layers
painting and editing are confined to opaque areas
of the layer. For example, if you lock a layer’s trans-
parency, you can edit an object without adding
opaque pixels to the transparent area outside the
object.
To lock all layer properties:
1
Select the layer in the Layers palette.
2
Click the Lock All icon at the top of the
Layers palette.
To protect the transparent areas in a layer from
editing:
1
Select the layer in the Layers palette.
2
Click the Lock Transparency icon at the top
of the Layers palette.
Note:
For type and shape layers, transparency is
locked by default and cannot be unlocked.
Painting with transparency locked
Sampling from all layers
By default, when you work with the magic wand,
smudge, blur, sharpen, or clone stamp tool, you
are applying color sampled only from pixels on the
active layer. This means you can smudge or sample
in a single layer even when other layers are visible,
and you can sample from one layer and paint in
another one.
Alternatively, you can choose to paint using
sampled data from all the visible layers. For
example, you can use the clone stamp tool to clone
an area containing pixels from all the visible layers.
To sample from all visible layers:
1
Select the magic wand tool
, paint bucket
tool
, smudge tool
, blur tool , sharpen
tool , or clone stamp tool
.
2
In the options bar, select Use All Layers. If you
selected the paint bucket tool, select All Layers.

Selecting opaque areas on a layer
You can quickly select all the opaque areas on a
layer within the layer boundaries. This is useful
when you want to exclude transparent areas from
a selection.
