Creating a Layer Set object
The following examples show how to create a
Layer Set
object after the creating the first
ArtLayer
object in the current document:
AS
tell application "Adobe Photoshop CS4"
make new document with properties {name:"My Document"}
make new art layer at beginning of current document
make new layer set after layer 1 of current document
end tell
VBS
Dim appRef
Set appRef = CreateObject("Photoshop.Application")
'Make a new document and a first layer in the document
appRef.Documents.Add()
appRef.ActiveDocument.ArtLayers.Add()
' Get a reference to the first layer in the document
Dim layerRef
Set layerRef = appRef.ActiveDocument.Layers(1)
' Create a new LayerSet (it will be created at the beginning of the document)
Dim newLayerSetRef
Set newLayerSetRef = appRef.ActiveDocument.LayerSets.Add
' Move the new layer to after the first layer
newLayerSetRef.Move layerRef, 4 'psPlaceAfter
JS
// make a new document and a layer in the document
app.documents.add()
app.activeDocument.artLayers.add()
// Get a reference to the first layer in the document
var layerRef = app.activeDocument.layers[0]
// Create a new LayerSet (it will be created at the beginning of the // document)
var newLayerSetRef = app.activeDocument.layerSets.add()
// Move the new layer to after the first layer
newLayerSetRef.move(layerRef, ElementPlacement.PLACEAFTER)
Referencing ArtLayer objects
When you create a layer in the Photoshop application (rather than a script), the layer is added to the Layers
palette and given a number. These numbers act as layer names and do not correspond to the index
numbers of
ArtLayer
objects you create in a script.
Your script—VBScript or JavaScript—will always consider the layer at the top of the list in the Layers
palette as the first layer in the index. For example, if your document has four layers, the Photoshop
application names them Background Layer, Layer 1, Layer 2, and Layer 3. Normally, Layer 3 would be at the
top of the list in the Layers palette because you added it last.
