I have a photoshop jsx script that will work through multiple folders of images to be focus-stacked and output a final stacked image for each. I want it to run non-interactively after telling it where the images are, as I may need it to crunch away for hours without me babysitting it. The script is pasted below.
The problem is that at the end of each stacking operation, a dialog box still appears, asking, Save changes to Adobe Photoshop document "Untitled-1" before closing? Yes / No / Cancel. I have included two lines of code that I thought would prevent this, but they don't do so:
app.displayDialogs = DialogModes.NO;
app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
The last of these two lines is where the prompt arises, and execution halts until I click No. How do I suppress it, have the close() function not save changes as it closes the document, and have the script continue?
I am running Adobe Photoshop 2020 21.2.0 release in Windows 10 Home 10.0.18363.
// auto_focus_stack.jsx
// Adapted from a script by SuperMerlin at
// https://community.adobe.com/t5/photoshop/automate-focus-stacking-script-action-help-needed/td-p/10483237?page=1
//
// Place this script in the Adobe Photoshop Presets Scripts directory.
//
// To run:
// * Create a top folder with subfolders inside.
// * Each subfolder should contain a series of images to stack into a single image and no other files.
// * Name each subfolder by the desired filename of the output stacked image, but omit the file extension.
// E.g., if the stacked image filename should be "NorthSide.jpg", then name the subfolder "NorthSide".
// The script will place the stacked images into a new subfolder called "processed" and will add the
// file extension in the file names.
// * Open Photoshop and start the script with File > Scripts > auto_focus_stack.
// * Select the top folder. Click Select Folder.
//
// The script will then create a "processed" subfolder, stack the images in each of the other subfolders,
// and save the stacked images in the "processed" subfolder.
