Automate Split to layers multiple transparent PNG files + Export in original DPI

[Marinapomorac]

Hello.

I discovered a script that works amazingly for what I need but... I need to automate it so I do not have to open each file individually and then export each layer as PNG (any other option reduces DPI of the original image in metadata).

https://photoshopscripts.wordpress.com/2012/12/09/split-to-layers/

So if anyone can assist, how to set up this action:
RUN Action
 a) it asks for input folder where all transparent PNG images are
b) it asks for pixel range or keeps the default at 10
c) it asks for the output folder
And then export each contiguous group of pixels to its own PNG file, keeping the same DPI (300).

Basically, just automate this script so it performs what it performs on multiple files without additional user interaction.

Thank you.
