Scripting A file saving process

[Akimo5C92]

Hello. So I am looking for script that...

Turns on the visibilty of a layer/group >

Saves it as a png(with the group name as the saved file name) >

Turns off the visibility of the layer and moves on to next.

Is this possible?

As for what it is for...I have 120 groups/layers after everything is arranged with a very specific name that helps the sorting process when they are in a folder. I have to do this 17 more times across the same amount of documents, so this automation script would be very much appreciated.

I have two versions of the same script in the following topic, one uses save and the other export save for web:

https://community.adobe.com/t5/photoshop-ecosystem-discussions/how-do-i-export-layers-as-png-without...

Modifications can be made as required.

Thank You good sir, will take a look and get back to you

[Akimo5C92]

You are an OG sir, Thank You! This was exactly what I was looking for.

Glad to be of help! For completeness, there is also the built-in script under File > Export > Layers to Files and you can also right-click on the layers in the layers panel and use Export As. The best method will depend on your requirements.

Edit: There are also a couple of scripts from Paul Riggott:

Layer Saver Plus.jsx

Layer Saver.jsx

Hello Stephen, I appreciate the additional information. I havent tried out the scripts but I want to ask if  you know a way for the script to run a bit or rather, a lot faster? (It is taking 4 straight day and counting to export)

[Stephen_A_Marsh]

If you are referring to the original two scripts that I linked to, the standard object model code to loop over all top-level layers could be changed to use action manager code, however, that is easier said than done (for me). Perhaps another scripter can help.

You could also see if changing the PNG quality options produces a faster save vs. quality.

If the process is taking too long, you should look to see if the two scripts from Paul Riggott are faster.

There is also the File > Export > Layers to Files script

Another option could be:

You did it again my friend. The "Layer Saver Plus" really did the trick(although I had to find another script to turn all the groups into layers to use it, it was worth it.) as it saves several hundreds of pngs within an hour.  Thank You Again!

Ohh, I spotted the word "group" in the code- I'll try it out when I get to the next batch of pngs. But thanks again man you have single handedly turned the task from a massively mind numbing, time wasting task to a breeze.

[Stephen_A_Marsh]

A layer set is the same thing as a layer group. Adobe changed the name/term in the software interface, however, scripting still uses the legacy term set and not group.
