How to use a script to retrieve existing ADOBE PDF presets in Photoshop using a dropdown menu?

I have written a script in Photoshop to retrieve ADOBE PDF presets, but it is only compatible with Windows 10 and above. However, the same approach should work for adapting it to Mac.

if (BridgeTalk.appName == "photoshop") {
  var userName = getCurrentUsername();
}

function getCurrentUsername() {
  var userName = $.getenv("USERNAME");
  if (!userName) {
    userName = $.getenv("USER");
  }
  return userName;
}

var dialog = new Window("dialog");
dialog.text = "Select PDF Preset";
dialog.orientation = "column";
dialog.alignChildren = "left";

var presetsDropdown = dialog.add("dropdownlist");
presetsDropdown.preferredSize.width = 200;

var loadButton = dialog.add("button", undefined, "Load");
loadButton.onClick = loadSelectedPreset;

var pdfPresets = getPDFPresets();
for (var i = 0; i < pdfPresets.length; i++) {
  var presetName = pdfPresets[i];
  presetsDropdown.add("item", presetName);
}

presetsDropdown.selection = presetsDropdown.items[1];
dialog.show();

function getPDFPresets() {
  var presetFolderPath1 = "C:\\Users\\" + userName + "\\AppData\\Roaming\\Adobe\\Adobe PDF\\Settings";
  var presetFolderPath2 = "C:\\ProgramData\\Adobe\\Adobe PDF\\Settings";
  var folder1 = new Folder(presetFolderPath1);
  var folder2 = new Folder(presetFolderPath2);
  var files1 = folder1.getFiles("*.joboptions");
  var files2 = folder2.getFiles("*.joboptions");

  var presets = [];
  for (var i = 0; i < files1.length; i++) {
    var file1 = files1[i];
    var name1 = file1.name.replace(/\.joboptions$/, "");
    presets.push(decodeURIComponent(name1));
  }
  for (var i = 0; i < files2.length; i++) {
    var file2 = files2[i];
    var name2 = file2.name.replace(/\.joboptions$/, "");
    presets.push(decodeURIComponent(name2));
  }

  return presets;
}

function loadSelectedPreset() {
  var selectedIndex = presetsDropdown.selection.index;
  var selectedPreset = pdfPresets[selectedIndex];
  alert("Loaded PDF Preset: " + selectedPreset);
}

@Aprking,

As @c.pfaffenbichler has already mentioned, you can get the joboptions-files’ names (»~/Library/Application Support/Adobe/Adobe PDF/Settings«).  but note that this will only be any "Custom pdf export presets" that you've created or loaded and not any of the built in ones.

Please see the working snippet below.

var myAdobePDF_Presets = Folder("~/Library/Application Support/Adobe/Adobe PDF/Settings");
var myCustomPresets = myAdobePDF_Presets.getFiles();

var myPresets = [];
for(var i = 0; i < myCustomPresets.length; i++){
    myPresets.push(myCustomPresets[i].name.replace(/%20/g, " ").slice(0, -11))
}

myPresets.unshift("- Select Preset -");
 
var myWin = new Window('dialog', 'PDF Export Presets');
myWin.orientation = 'row';
with(myWin){
    myWin.sText = add('statictext', undefined, 'Select PDF Export preset:');
    myWin.myPDFExport = add('dropdownlist',undefined,undefined,{items:myPresets});
    myWin.myPDFExport.selection = 0;
    myWin.btnOK = add('button', undefined, 'OK');
    };
myWin.center();
var myWindow = myWin.show();

No, not according to the documentation (»photoshop-cc-javascript-ref-2019.pdf«).

But as far as I know the pdf presets are not application-specific so you should be able to use the list from Indesign or Illustrator. (Which you should be able to retrieve via BridgeTalk.)

Or »simply« get the joboptions-files’ names (»~/Library/Application Support/Adobe/Adobe PDF/Settings«).
