Script to save a file in a specific folder with a specific name

[Stephane27925305ylf8]

Hello,

I found a very useful script to save covers as JPEG, with a fixed width, whatever is the original size :

//the export pixel width
var targetWidthPixels = 600;

var doc = app.activeDocument;
with(doc.viewPreferences){
    horizontalMeasurementUnits = MeasurementUnits.INCHES;
    verticalMeasurementUnits = MeasurementUnits.INCHES;
}

//get the page width in inches
var pw=doc.documentPreferences.pageWidth;

//calulate the resolution needed to export the jpeg as 1500px wide
//if the page is 8.5" x 11", the output pixel dimensions will be 600px x 776px
var resout= targetWidthPixels/pw;

//the active page
var pg=app.activeWindow.activePage.name;

//set the res preference and page range
 with(app.jpegExportPreferences){
     exportResolution = resout;
     pageString = pg;
     antiAlias = true;
     embedColorProfile = true;
     jpegColorSpace = JpegColorSpaceEnum.RGB;
     //add other properties as needed
}
 
//export the JPEG
doc.exportFile(
		ExportFormat.jpg,
		File(Folder.desktop + "/ExportJPG.jpg"), 
		false
);

My question is : how to put this file in a specific folder (/Users/toto/Desktop/TEST MTP/OUT site) with a specific name wich is the 14 first characters of every Indesign file name (9782340-046337_COUV_2022_02_24.indd becomes 9782340-046337.jpg)

Thanks for your Help

No, it's just that the script does not launch when I play it on the PC. Just Nothing…

Could you please post your latest code again - using:

Here it is, with a more simple target adress on the PC…

[Stephane27925305ylf8]

//the export pixel width
var targetWidthPixels = 1000;

var doc = app.activeDocument;
with(doc.viewPreferences){
    horizontalMeasurementUnits = MeasurementUnits.INCHES;
    verticalMeasurementUnits = MeasurementUnits.INCHES;
}

//get the page width in inches
var pw=doc.documentPreferences.pageWidth;

//calulate the resolution needed to export the jpeg as 1500px wide
//if the page is 8.5" x 11", the output pixel dimensions will be 600px x 776px
var resout= targetWidthPixels/pw;

//the active page
var pg="Print:3";

//set the res preference and page range
 with(app.jpegExportPreferences){
     exportResolution = resout;
     pageString = pg;
     antiAlias = true;
     embedColorProfile = true;
     jpegColorSpace = JpegColorSpaceEnum.RGB;
     //add other properties as needed
}

//export the JPEG
doc.exportFile(
		ExportFormat.jpg,
		File("C:\Users\louis\Documents\TEST_MTP\OUT" + doc.name.substring(0,13) + ".jpg"), 
		false
);

And a screen capture of my pages on Indesign

JavaScript is case sensitive, so it rather should be:

ExportFormat.JPG

in the exportFile()?

https://www.indesignjs.de/extendscriptAPI/indesign-latest/#ExportFormat.html

But, it's the same in your original code - that was working on Mac? 

[Stephane27925305ylf8]

OK thanks, I will try it although it works like that on MacOS 🙂

I think you want forward slashes for the file path—try this:

doc.exportFile(ExportFormat.jpg, File("C:/Users/louis/Documents/TEST_MTP/OUT/" + doc.name.replace(RegExp('()?\.[^\.]+$'), '') + ".jpg"), false);

//returns C:/Users/louis/Documents/TEST_MTP/OUT/MyExportDocument.jpg for a doc named MyExportDocument.indd

@rob day

Why? Windows prefers "\".

[rob day]

This is what I get  for VS Code and it fails on OSX:

$.writeln("C:\Users\louis\Documents\TEST_MTP\OUT" + doc.name.replace(RegExp('()?\.[^\.]+$'), '') + ".jpg")

//returns C:UserslouisDocumentsTEST_MTPOUTMyExportDocument.jpg

Or if I get the ID document’s .filePath the file path string returns as this

 $.writeln(doc.filePath)
 //returns ~/~FISHERCAT%20ONGOING/CLOUD%20ONGOING%20/Dropbox/SCRIPTING

@rob day

So writeln is stripping all "\"??

OK, because all "\" need to be doubled.

I think ExtendScript wants the folder path in URI notation so it is cross platform:

[Stephane27925305ylf8]

Yes! Thanks very much, it works! 🙂

But… Instead of having the specific page as requested here in the script :

//the active page
var pg="Print:3";

It exports all the pages of the document :-((

I make my tests with exactly the same Indd document on Mac and on PC.

You’ll need to set range rather than all in the jpegExportPreferences by adding jpegExportRange

//set the res preference and page range
    with(app.jpegExportPreferences){
        exportResolution = resout;
        jpegExportRange = ExportRangeOrAllPages.EXPORT_RANGE;
        pageString = pg;
        antiAlias = true;
        embedColorProfile = true;
        jpegColorSpace = JpegColorSpaceEnum.RGB;
        //add other properties as needed
    }

If that doesn’t work you might need to get the page string:

var pg=app.activeWindow.activePage.name;

[rob day]

Try running this:

var f = Folder.selectDialog("Select a Destination Folder"); 
if(f != null){ 
    alert(f)
}

I get:

[rob day]

Hi @Stephane27925305ylf8 , you could also choose the destination folder from the script, something like this"

//Choose a folder
var f = Folder.selectDialog("Select a Destination Folder"); 
if(f != null){ 
    app.scriptPreferences.measurementUnit = MeasurementUnits.INCHES;

    //the export pixel width
    var targetWidthPixels = 600;

    var doc = app.activeDocument;
    //use the document’s name for export
    var n = doc.name.replace(RegExp('()?\.[^\.]+$'), '');

    //get the page width in inches
    var pw=doc.documentPreferences.pageWidth;

    //calulate the resolution needed to export the jpeg as 1500px wide
    //if the page is 8.5" x 11", the output pixel dimensions will be 600px x 776px
    var resout= targetWidthPixels/pw;

    //the active page
    var pg=app.activeWindow.activePage.name;

    //set the res preference and page range
    with(app.jpegExportPreferences){
        exportResolution = resout;
        pageString = pg;
        antiAlias = true;
        embedColorProfile = true;
        jpegColorSpace = JpegColorSpaceEnum.RGB;
        //add other properties as needed
    }
    //export the JPEG
    doc.exportFile(ExportFormat.jpg, File(f + "/" + n + ".jpeg"), false);
    app.scriptPreferences.measurementUnit = AutoEnum.AUTO_VALUE;
}

Thank you Rob, I'll try that (even if my goal is always the same place on the computer)
