Script to save as png file with a specific name and put it in a specific folder.

I use 3D application and Photoshop at the same time.

I use Photoshop to edit textures and export them as png and see how it looks in 3D application.

For example I open psd file and edit image and export image as png with name "texture.png" and put it in a folder "D:\textures", and check how it looks in 3D application. After that I am going back to Photoshop and edit same image and export it as png with same name "texture.png" and put it in the same folder "D:\textures" and check it again in 3D appllication. I need to do this again and again. Right now I do this manually. it's really time consuming, so I would like to know if it is possible to automate it with jsx script or not. I would like to automate three process "save image as png","name it a specific name","and "put it in a specific folder." jsx can do it automattically?

I was delayed by some unexpected errors and debugging when I used your PNG save code, so I went back to my previous code. I also got bogged down a bit in exploring some edge-case error checking, hoping to improve on the code used in earlier scripts. It is all in one script, there is no need for two separate scripts, but that is OK too if you prefer it that way (I used to do that until I found out about keyboardState). The ALT/OPT key has to be depressed while the script is run to set the save location. Thereafter, the save location will continue to be used until the script is run again with the ALT/OPT key held down.

Anyway, please try the following v1.0 code.

it works. thank you. Nice script. I like alt key conditional branch.

I always use jsx script as action button,is it supposed to be used as action button,right?

Because I can't push alt key when I execute jsx from "File - Script" menu.

Stephen Marsh

The alt/opt key can be used when accessing an installed script or when browsing a script from the menu. Hold down the key first before accessing the menu and then let go after the script is selected. I have tested this on the Mac and Windows OS in v2021 and v2022.

You may need to split the contents of the conditional into two separate scripts for use with an action based workflow if the alt/opt modifier isn't recognised (unless somebody else knows differently).

I wrote a script. It uses active layer name and save current layer state of psd file as png file.

Problem is save location is where the psd file is.And I use this png format, nothing special.

var docPath = app.activeDocument.path.fullName
var layerName = app.activeDocument.activeLayer.name
var newFileName = docPath.concat( "/", layerName, ".png")

fileObj = new File( newFileName )
pngOpt = new PNGSaveOptions();
pngOpt.interlaced = false;
activeDocument.saveAs(fileObj, pngOpt, true, Extension.LOWERCASE);

I think what I need is two jsx files. 1st jsx to decide save location, and 2nd jsx to save png file. 1st jsx must have this.

var folderLocation = Folder.selectDialog("select folder");

and once I set the folder location manually using Photoshop dialogue box I would like to use this folderLocation variable again and again. Is it possible? I guess I need to save folderLocation variable somewhere else? as txt format or something?

2nd jsx needs to use this folderLocation variable and saves png file.If I use the variable with above script It must be like this.

var docPath = folderLocation

And when I need to change save location I am gonna run that 1st jsx to decide folder location again and let 2nd jsx use renewed folderLocation variable and save png. Is this possible?

That helps but you didn't answer my specific question whether the save location should be remembered after exiting Photoshop.

Rodan_ShinerAuthor

I would like keep the location in txt file after exiting Photoshop to reuse it.

Chuck Uebele

That makes it a lot more complicated. So are you saving/exporting only a few layers each time, say just the diffusion layer and some adjustment layers? If so, are all the layers that you want to save in one group? If you're not putting them in a single group, it would be difficult to let the script know which layers need to be save together. The group should be named how you want the file named, like "texture\diffusion." To make the script more simple to get the file structure to save, the name should be in the order of the folder hierarchy and use back slashes, rather than forward slashes.

R

Rodan_ShinerAuthor

I can put them in a layer folder. it sounds like folder name can be used to name a file and save it in a specific folder? llike layer folder name "D:\textures\diffuse.png" and put it in a variable?

Chuck Uebele

Community Expert

Yes, you can do that, but using the scripting Convention it would be best to write the name like this: " D\textures\diffuse" as you don't need the colon, if you use back slashes. Also if all your saved files are the same name as the last word, then you wouldn't need to add .png to the name. To define a folder in a script would look like this:

var diffuseFolder = new Folder ('\d\diffuse\');

Thank you. What I would like to do is written on replay to Chuck Uebele. I should have said that.Sorry.

var outputFolder = Folder("d:\\textures");
var pngName = "texture.png";

your scipt needs those two variables, but image name and folder name are changed.

In Photoshop, when I save image, at least Photoshop remembers last folder location.

So how about this. I save a image "diffuse_texture.png"manually in a folder "D:\textures\diffuse" and after that jsx does same thing again and again. I would like it to do "save image as png and name it diffuse_texture.png in a folder D:\textures\diffuse". And when I've done editing diffuse map then I start editing normal map. I manually save "normal_texture.png" in a folder "D:\textures\normal" and after that jsx does same thing again and again. Is it possible? I always use same file format, so it dosn't need to be changed, but file name and folder location need to be changed.jsx can have variables "last used folder name" and "last used folder location"?

Stephen Marsh

Community Expert

Yes, it would have been helpful to fully specify the process from the beginning.

OK, it is possible to remember the last save location and reset a save location etc. Do you need this to be remembered between Photoshop sessions (after a quit and restart of the software) or will you always be saving in the same open running session and don't need the last path to be remembered after exiting Photoshop?

Which PNG method is better for your 3D software, the Save As or Export Save for Web?

Chuck Uebele

Community Expert

This sounds pretty basic and shouldn't be hard. When you same name the file and put it in a folder, is the name always the same, and is the folder always the same? If so, that info can be coded into a script.

R

Rodan_ShinerAuthor

I will be more specific..

For example, like I said before I open psd file which has lots of layers.

it has UV maps,diffuse maps,specular maps,roughness maps,normal maps, an adjustment layers. And I need to edit it. When I need to edit diffuse map, I edit diffuse map layers and related adjustment layers, and when I need to edit normal map, I edit normal map layers and related adjustmen layers.Same things goes with other maps.And when I've done editing I need to export them individually. I export diffuse map as "diffuse_texture.png" and put it in "D:\textures\diffuse", and I export normal map as "normal_texture.png" and put int in "D:\textures\normal".

So file name is not always same.And folder isn't same too. I awalys edit mutliple images and export them.

You can record action but if you are familiar with script I will tag few of them who can assist you @c.pfaffenbichler @jazz-y @Stephen Marsh

You need action or script in case that you have layered file in Photoshop, otherwise save and keep open texture.png in Photoshop, change it, then use Save to save back changes.

Thank you. I need to edit psd which have layers and I need to save multiple images.
