The Photoshop CS3 object model contains two types of layer objects: 

●

ArtLayer

 objects, which can contain image contents and are basically equivalent to Layers in the 

Photoshop CS3 application. 

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

. 

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.

The following examples demonstrate how to create an 

ArtLayer

 object filled with red at the beginning of 

the current document.

tell application "Adobe Photoshop CS3"

make new document
make new art layer at beginning of current document ¬

with properties {name:"MyBlendLayer", blend mode:normal}

select all current document
fill selection of current document with contents ¬

{class:RGB color, red:255, green:0, blue:0}

end tell
