I am developing an Adobe extension, from within the extension I want to load a directory of images into separate layers within a document. I am completely impartial to how this is done - so if there is a better approach, please share it with me. My current working method involves using the open() method which opens a file in a new document, then duplicate the layer of the new document into the original document. An example of this can be seen below.

// open new document
var originalDoc = app.activeDocument;
var doc = open( new File( filePath ) );

// duplicate to original document
var layer = doc.activeLayer;
var newLayer = layer.duplicate(originalDoc, ElementPlacement.PLACEATBEGINNING);

// close new document
doc.close(SaveOptions.DONOTSAVECHANGES);

This method is extraordinarily slow, especially for large images. After doing some Googling I discovered that Photoshop has a built-in method for creating an image stack. This feature uses a .jsx script itself and it can be found on GitHub. Looking around online I found a few people trying to load a folders contents as layers, perfect. The main code I was interested in is below.

var folder = new Folder('~/Desktop/MyFolder');
function runLoadStack(folderPath) {
    var loadLayersFromScript = true;
    // @include 'Load Files into Stack.jsx'
    var fList = folder.getFiles('*.png')
    var aFlag = true;
    loadLayers.intoStack(fList, aFlag);
}
runLoadStack(folder)

I immediately noticed the @include method of importing the stack methods, I can not find any official documentation for this (also not friendly with minification). Also, if the script is not placed with the same directory as Load Files into Stack.jsx it will throw the error Unable to open file: anonymous. And even after solving all of these issues when I run the .jsx script from within my extension using $.evalFile() I am having the same error as if the script is not in the correct directory: Unable to open file: anonymous. Error is being thrown on line 762 of an imported jsx.

Any help resolving the error I am experiencing or simply on how to load an array of image paths into layers (faster method) will be greatly appreciated!

Here is the code I am using within my extension:

var loadLayersFromScript = true;
var strPresets = localize("$$$/ApplicationPresetsFolder/Presets=Presets");
var strScripts = localize("$$$/PSBI/Automate/ImageProcessor/Photoshop/Scripts=Scripts");

var jsxFilePath = app.path + "/" + strPresets + "/" + strScripts + "/Load Files into Stack.jsx";

$.evalFile( new File( jsxFilePath ) );
loadLayers.intoStack( new Folder("/c/Users/Me/teststack").getFiles(), true );

    Just to clarify: you're trying to run the script from CEP extension, it doesn't have any `@include`'s anymore and you're including the `.jsx` files using the `$.evalFile()` providing a full path to jsx files? – Sergey Kritskiy Oct 11 '19 at 10:02
  • Yes that is correct on both questions. I have even tried including the files which are `eval`'d within `Load Files into Stack.jsx` into one big file, same result. – EvilZebra Oct 11 '19 at 14:54

Photoshop's inbuilt scripts has a script to do this here's the github link

https://github.com/ES-Collection/Photoshop-Scripts/blob/master/Import%20Folder%20As%20Layers.jsx

use this script inside your CEP extension
