InDesign: Script for exporting layers to jpg

Question

Hello

I'm looking for a Script that is capable to export my layers in a .indd file to jpgs in a Folder which I can choose. Also the Script need to name the exportet jpg's as the layer is named in the inDesign file.

Anyone an Idea how to makte this happen?

Thanks in advance!

Yes you can export a selection. Selection is an array, so if the selection is more than one object you would have to handle how to group the pageitems. It could get complicated if the page items are on different layers. By default a page item’s name returns as nothing unless it has been named in the Layers panel, but the name could also be scripted. Something like this, which exports to the desktop:

app.jpegExportPreferences.properties = {
    antiAlias: true,
    embedColorProfile: true,
    exportResolution: 72,
    jpegColorSpace: JpegColorSpaceEnum.RGB,
    jpegQuality: JPEGOptionsQuality.maximum,
    simulateOverprint: false,
  }

var sel = app.documents[0].selection[0];
var lay = sel.itemLayer;
var pin = sel.name;
//sel.name returns as "" by default
if (sel.name == "") {
	pin = "mySelection"
} 

//the jpg name for export—the selection’s Layer - the selection’s name + .jpg
var fn = "/" + lay.name + "-" + pin +".jpg"
$.writeln(sel.name)

sel.exportFile(ExportFormat.jpg, File(Folder.desktop + fn));

You're the man! With a few changes and your Script, it works!

For everyone wondering how to do it, this is my take, bases on @rob day 's soulution:

app.jpegExportPreferences.properties = {
	antiAlias: true,
	embedColorProfile: true,
	exportResolution: 300,
	jpegColorSpace: JpegColorSpaceEnum.RGB,
	jpegQuality: JPEGOptionsQuality.maximum,
	simulateOverprint: false,
}

	var myFolder = Folder.selectDialog ("Select location to export the Jpeg files.");
	if (myFolder != null) {
		var mySelection = app.selection;
		if (mySelection.length > 0) {
			for (var i = 0; i < mySelection.length; i ++) {
				var exportedSelected = mySelection[i];
				var selectedLayer = exportedSelected.itemLayer;				
				var layerName = "/" + selectedLayer.name + ".jpg";
				exportedSelected.exportFile(ExportFormat.jpg, File(myFolder + layerName));		
			}		
		} else {
			alert("Please select at least one Layer!");
		}		
	}

Hello @OPTEN,

The below code is a bit more simplified.... I included the page # in the output name just to account for multi page documents, you can modify the code as needed.

var doc = app.activeDocument;

var myFolder = Folder.selectDialog ("Select location to export the Jpeg files.");
if (myFolder != null){ 
}else{
exit();
}

for(var p = 0; p < doc.pages.length; p++) {
var myPageName = doc.pages[p].name;

function myGetVisibleLayers(){
 var myVisibleLayers = new Array;
  for (var i = 0; i < doc.layers.length; i++){
   if (doc.layers[i].visible == true) {   
    myVisibleLayers.push(doc.layers[i].index);
      }
   }
      return myVisibleLayers;
  }

  var myVisibleLayers = myGetVisibleLayers();
      
  doc.layers.everyItem().visible = false;

  for (var i = 0; i < doc.layers.length; i++) {

  var my_layer = doc.layers[i].name;

  doc.layers[i].visible = true;

// Set JPEG export preferences 
app.jpegExportPreferences.properties = {
    antiAlias: true,
    embedColorProfile: true,
    exportResolution: 150,
    // exportingSpread: true, // Uncomment if spreads
    jpegColorSpace: JpegColorSpaceEnum.rgb,
    jpegExportRange: ExportRangeOrAllPages.exportRange,
    jpegQuality: JPEGOptionsQuality.maximum,
    jpegRenderingStyle: JPEGOptionsFormat.PROGRESSIVE_ENCODING,
    useDocumentBleeds: false,
    simulateOverprint: false,
    pageString: myPageName,
  }

 doc.exportFile(ExportFormat.jpg,File(myFolder + "/" + my_layer + "_pg" + myPageName + ".jpg"),false);

  doc.layers[i].visible = false;
}
  doc.layers.everyItem().visible = false;

  for (var i = 0; i < myVisibleLayers.length; i++){  
    var myLayers = myVisibleLayers[i];
    doc.layers[myLayers].visible =  true; 
    }
}
 alert("Done Exporting Layers to Jpeg's!");

Regards,

Mike
