Reply To: Automate change object layer option

I solved my problem – partly but enough for me. A little adjustment to the LayerVisibility script worked for me.
Just go to InDesign and set a particular layer current. Then run the script that you filled with the two PhotoShop layers that should be present in all images (ignoring any other that might be there) and run it. That script works fine with a little more handwork than I hoped for, but it beats manually modifying each InDesign Object Layer Option.

Main();

//
// set layers on/off in an image or images on one InDesign page
//
function Main()
{
var page, placedFile, links, layer, i, j, k, doc;
var doc = app.activeDocument;
var curLayer = doc.activeLayer;
var pages = doc.pages

var checklist = [];

var PSlayernames = [ “extreme”, “subtle” ];

/* ——————————————————————————————————-
ABOVE IS WHERE YOU ALTER THE LAYER NAMES:
After the words “var layernames” there’s an opening square bracket , then some sets of text enclosed in quotes sperated by commas, and at the end, a closing square bracket.
Delete all of the text and the commas separating it, and in its place put in any layers that you want.
For example: If you have three layers, ‘red’, ‘green’ and ‘silver’, then in the brackets put in each layer enclosed in quotes and seperated by a comma, as such: [“red”, “green”, “silver”].
Make sure they are all double-quotes, not single quotes, and make sure they are ‘straight’ quotes not ‘smart’ quotes.
To ensure that it’s properly formatted, only edit the script in a generic text editor (such as Notepad on Windows, or Text Wrangler on Mac).
DO NOT use a word-proccesing program such as MS Word or InDesign, as that will add formatting to the script and it will not work properly.
