Composition > Scripting

[PhilM]

Is it possible to use VBscript to browse around existing compositions ?
Or to create a new composition ?

I don't see the composition object in the scripting manual.

Best regards.

Is it possible to use VBscript to browse around existing compositions ?

IPLDocument has two properties regarding layer compositions:

• ActiveLayerComposition: Returns the name of the active layer composition (or an empty string if there is none)
• LayerCompositions: Returns an array of IPLDictionary objects. Each dictionary has two entries:
  • "name": The name of the composition.
  • "description":The description of the composition

The following VBScript queries the layer compositions and activates the second one (the one with the index 1):

Code: Select all

Dim pl
Dim doc

Set pl = CreateObject("PhotoLine.Application")
Set doc = pl.ActiveDocument

If Not doc Is Nothing Then
	Dim layerComps

	pl.Visible = True
	
	layerComps = doc.LayerCompositions
	'WScript.Echo "Number of compositions: " & UBound(layerComps)
	
	If (UBound(layerComps) > 1) Then
		doc.ActiveLayerComposition = layerComps(1)("name")
	End If
End If

Or to create a new composition ?

There's no way to create a layer composition by script.

I don't see the composition object in the scripting manual.

The documentation will be added when scripting of layer compositions is added to the official version.

Thanks !

Is scripting of layer compositions available in the last Beta B18 ?

Yes.

Both V24.01 and Beta 18 give me an error on line 11 of the script that the object does not handle the "LayerCompositions" property or method.

24.01 doesn't support scripting of layer compositions.
The script works fine here with B18.

Did you remember to activate scripting for B18?

Understood ...
Yes it does work.

Thanks a lot.

What is the syntax to retrieve the index (0, 1, 2 ...) of the active composition ?

Thanks

There is none. Depending on what you want to to, you can either check the name of the composition or you'll have to find it "manually". The following script activates the next layer composition.

Code: Select all

Dim pl
Dim doc

Set pl = CreateObject("PhotoLine.Application")
Set doc = pl.ActiveDocument

If Not doc Is Nothing Then
	Dim comps
		
	comps = doc.LayerCompositions
	' Is there more than 1 layer composition?
	If (UBound(comps) > 1) Then
		Dim activeCompName
		' Determine index of active layer composition
		activeCompName = doc.ActiveLayerComposition
		For i = 0 To UBound(comps)
			cmp = StrComp(comps(i)("name"), activeCompName)
			If (cmp = 0) Then
				Exit For
			End If
		Next
		' Switch to next layer composition
		i = i + 1
		' If there was no layer composition or the last one is the
		' active one, activate the first.
		If (i > UBound(comps)) Then
			i = 0
		End If
		doc.ActiveLayerComposition = comps(i)("name")
	End If
End If

Thank you
This does the job
