Layer copyToComp() method
a p p . p r o j e c t . i t e m ( i n d e x ) . l a y e r ( i n d e x ) . c o p y T o C o m p ( i n t o C o m p )
Description
Copies the layer into the specified composition. The original layer remains unchanged. Creates a new Layer
object with the same values as this one, and prepends the new object to the
l a y e r s
collection in the target
CompItem. Retrieve the copy using
i n t o C o m p . l a y e r ( 1 )
.
Copying in a layer changes the index positions of previously existing layers in the target composition. This is
the same as copying and pasting a layer through the user interface.
Parameters
Returns
Nothing.
Layer duplicate() method

Description

same effect as selecting a layer in the user interface and choosing Edit > Duplicate, except the selection in the
user interface does not change when you call this method.
Parameters
None.
Returns
Layer object.
