(Photoshop) Select Use Video Alpha to enable
Photoshop to send transparency information to
your computer's video board. This option requires
hardware support—make sure that your
computer's video board allows images to be
overlaid on top of a live video signal. Selecting this
option without hardware support produces
unpredictable results.
Click OK.

Changing the stacking order of layers
The stacking order determines whether a layer or
layer set appears in front of or behind other layers.
Note that you cannot drag a layer set into another
layer set or drag layer effects below the
background. For more information about the
stacking order in layers, see "Grouping layers into
sets" on page 213.
To change the order of a layer:
1
In the Layers palette, select the layer or layer set
that you want to move.
2
Choose Layer > Arrange, and choose an option
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).
To change the order of layers by dragging:
In the Layers palette, select the layer or the layer
1
set you want to move.
Drag the layer up or down in the Layers palette.
2
When the highlighted line appears in the desired
position, release the mouse button.
Note: By default, the background cannot be moved
from the bottom of the layer list unless it is first
converted to a layer. (See the procedure to convert a
background into a layer in "Adding layers" on
page 210.)
Linking layers
By linking two or more layers, you can move their
contents together. You can link layers outside a
layer set to each other, to a layer within a layer set,
or to the entire layer set. You can also link a layer in
a layer set to a layer contained in another layer set
or to a layer that is not part of a layer set. Once you
link to a layer set, the layers within the layer set are
implicitly linked.
By linking layers and layer sets, you can move their
contents together. You can also perform the
following tasks on linked layers and layers in a set:
•
Apply transformations.
For more information, see "Transforming
objects in two dimensions" in online Help.
•
Align layer contents. (See "Moving and aligning
the contents of layers" on page 214.)
•
Merge layers. (See "Merging layers" on
page 247.)
•
Create clipping groups. (See "Creating clipping
groups" on page 218.)
