Working with layer objects
The Photoshop object model contains two types of layer objects:
➤
ArtLayer
objects, which can contain image contents and are basically equivalent to Layers in the
Photoshop application.
N
OTE
: An
ArtLayer
object can also contain text if you use the
kind
property to set the
ArtLayer
object’s type to text layer.
➤
Layer Set
objects, which can contain zero or more
ArtLayer
objects.
When you create a layer you must specify whether you are creating an
ArtLayer
or a
Layer Set
.
N
OTE
: Both the
ArtLayer
and
LayerSet
objects have corresponding collection objects,
ArtLayers
and
LayerSets
, which have an
add/Add/add()
command.You can reference, but not add,
ArtLayer
and
LayerSet
objects using the
Layers
collection object, because, unlike other collection objects, it does not
have an
add/Add/add()
command.
