Save As PNG script

[Simonezzzz]

Hello,

I'd like some help with this script if possible

I wanted to save my open file to PNG format in the same location with the same name. I managed to do that with the scripts below.

This is a script I found on the forum:

#target photoshop
main();
function main(){
if(!documents.length) return;
try{
    var Path = decodeURI(activeDocument.path.parent);
    }catch(e){return;}
if(!Folder(Path).exists){
    alert(Path + " Does not exist!");
    return;
    }
var Name = decodeURI(app.activeDocument.name).replace(/\.[^\.]+$/, '');
var saveFile = File(Path + "/" + Name + "_bump.png");
sfwPNG24(saveFile);
//Uncomment the line below if you want to close the document.
//app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
}
function sfwPNG24(saveFile){
var pngOpts = new ExportOptionsSaveForWeb;
pngOpts.format = SaveDocumentType.PNG
pngOpts.PNG8 = false;
pngOpts.transparency = true;
pngOpts.interlaced = false;
pngOpts.quality = 100;
activeDocument.exportDocument(new File(saveFile),ExportType.SAVEFORWEB,pngOpts);
} 

And this is how I modified it (so that it saves the file in the same folder and doesn't add any suffix to the name; also changed to save as PNG instead of using save for web):

#target photoshop
main();
function main(){
if(!documents.length) return;
try{
    var Path = decodeURI(activeDocument.path);
    }catch(e){return;}
if(!Folder(Path).exists){
    alert(Path + " Does not exist!");
    return;
    }
var Name = decodeURI(app.activeDocument.name).replace(/\.[^\.]+$/, '');
var saveFile = File(Path + "/" + Name + ".png");
sfwPNG24(saveFile);
//Uncomment the line below if you want to close the document.
//app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
}
function sfwPNG24(saveFile){
var pngOpts = new PNGSaveOptions;
pngOpts.compression = 9;
pngOpts.interlaced = false;
activeDocument.saveAs(saveFile, pngOpts, true, Extension.LOWERCASE); 
}

My problem:

I don't know what's happening when I try to save a file just created (never saved yet). I thought I would get the Alert message but it doesn't seem to be the case (maybe the alert message in the code is related to a different condition?)

I would like to have a default folder/path in the code so that, if the file hasn't been saved yet, it would be saved in the specified location.

If anyone could do it I would really appreciate it!

Thanks

did not get that far.... Your catch ended the script without a notice to you. Try the changed line below in the catch.

#target photoshop

main();

function main(){

if(!documents.length) return;

try{

    var Path = decodeURI(activeDocument.path);

    }catch(e){alert(e); return;}   //Let the user know about the problem

if(!Folder(Path).exists){

    alert(Path + " Does not exist!");

    return;

    }

var Name = decodeURI(app.activeDocument.name).replace(/\.[^\.]+$/, '');

var saveFile = File(Path + "/" + Name + ".png");

sfwPNG24(saveFile);

//Uncomment the line below if you want to close the document.

//app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);

}

function sfwPNG24(saveFile){

var pngOpts = new PNGSaveOptions;

pngOpts.compression = 9;

pngOpts.interlaced = false;

activeDocument.saveAs(saveFile, pngOpts, true, Extension.LOWERCASE);

}

4 years later and this helped me^

gotta love the internet, thanks JJ-Mack!

I have appropriate this script to save PNG files in my workflow. It works great, but I have one question:

How can I change it to NOT flatten the file? I use a different script to merge all layers and name the remaining layer. This name is lost when I save the PNG with the script from this thread. I assume one of the settings in this function can be change to NOT flatten. What would it be?

function sfwPNG24(saveFile){
var pngOpts = new PNGSaveOptions;
pngOpts.compression = 9;
pngOpts.interlaced = false;
activeDocument.saveAs(saveFile, pngOpts, false, Extension.LOWERCASE);
}

Thanks!

PNG does not support layers. To achieve this, you can save the file to TIFF with this option:

TiffSaveOptions.layers = true;   

[rcraighead]

PNG with transparency are saved as a layer. At least when I save a PNG through the interface I retain the named layer when reopened.

Technically perhaps it is not a layer but PS treats it as such because it retains the name and… is transparent.

If I get it right, change

activeDocument.saveAs(saveFile, pngOpts, true, Extension.LOWERCASE);

Thanks for the suggestion, r-bin. I tried changing that and saw no difference. After trying again I realize it DOES keep the layer but replaces the custom name with "Layer1".
