Flatten image for all open documents

[niyetkhan]

Hello!

I often have this:

I open several files at once and create layers in them. Then I need to flatten image in all open documents.

Is it possible to make it at once and to write it down in the script?

Sincerely,

Niyetkhan

I understand your workflow, however such as script is fraught with danger, so file under the cateogory of "be careful what you wish for"! This script will flatten, save and close all open docs, use at your own risk!

This script assumes that all open images have been previously saved from Photoshop.

    if (!confirm("Are you really sure that you wish to flatten, save and close all open docs?", false)) {
        //throw alert("Script cancelled!");
        throw null;
    }

    // LOOP OVER OPEN FILES
    while (app.documents.length > 0) {
        app.activeDocument.flatten();
        app.activeDocument.close(SaveOptions.SAVECHANGES);
    }

    // END OF SCRIPT NOTIFICATION
    app.beep();

// ALERT IF NO DOCS OPEN
} else {
    alert('You must have a document open!');
}

This version will just flatten all open docs, without saving or closing (probably closer to what you were looking for than the previous script).

Adobe installs a Photoshop Script that will do the for you in Photoshop. Photoshop menu File>Scripts>Image Processor... You can at the same time save layered versions of your  open documents by saving a PSD  or Tiff version as well as a flat jpeg file.
