[Scripting] Export each artboard as a JPG

Hello, I know you can select use multiple artboards for jpg export manually, but there doesn't seem to be a corresponding property in the DOM. I tried some of the solutions mentioned here, but I am still getting the full file for each export. 

Here is my routine. Am I missing something?

 

    var exportOptions = new ExportOptionsJPEG();
        exportOptions.artboardClipping = true;
        exportOptions.antiAliasing = false;
        exportOptions.quality = 100;    
    var doc = activeDocument;
    var outfol = Folder.desktop;
    var type = ExportType.JPEG;
    var dn = decodeURI(doc.name);
    var dnrx = /\.ai$/gi;
    var abs = doc.artboards;
    var n = abs.length;
    var i = 0;
    var fname;
    for (i; i < n; i++) {
        fname = dn.replace(dnrx,"-" + "0" + (i+1).toString().slice(-2) + ".jpg");
        abs.setActiveArtboardIndex(i);
        doc.exportFile(File(outfol + "/" + fname), type, saveOptions);
    }
    doc.close(SaveOptions.DONOTSAVECHANGES);

In Illustrator 2018 or later, it is easier to use exportForScreens.

Script for ExportForScreensOptionsJPEG() not working.

 

If you are on macOS, you can find the documentation here.

Hi @brianp311, it doesn't seem to be documented properly, but if you look at, say, ExportOptionsSVG, you will see two properties that you can set in your ExportOptionsJPEG: artboardRange and saveMultipleArtboards.

Thanks, Mark. I tried saveMultipleArtboards = true, with nothing. I then iterated through the artboards and set exportOptions.artboardRange = abs[i].name and exporting each file that way, and still got 5 versions of the full doc. Is there some default preference maybe that I need to set?

Updated code: 

 

var exportOptions = new ExportOptionsJPEG();
        //exportOptions.artboardClipping = true;
        exportOptions.saveMultipleArtboards = true;
        exportOptions.antiAliasing = false;
        exportOptions.quality = 100;    
    var doc = activeDocument;
    var outfol = Folder.desktop;
    var type = ExportType.JPEG;
    var dn = decodeURI(doc.name);
    var dnrx = /\.ai$/gi;
    var abs = doc.artboards;
    var n = abs.length;
    var i = 0;
    var fname;
    for (i; i < n; i++) {
        fname = dn.replace(dnrx,"-" + "0" + (i+1).toString().slice(-2) + ".jpg");
        exportOptions.artboardRange = abs[i].name;
        abs.setActiveArtboardIndex(i);
        doc.exportFile(File(outfol + "/" + fname), type, exportOptions);
    }
    doc.close(SaveOptions.DONOTSAVECHANGES);

Eureka! I (kind of) figured it out. I had artBoardRange as artboardRange. Why wouldn't it throw an error!?!?! Now, how can I ensure that this exports at 300dpi? I tried setting exportOptions.resolution = 300, but still coming out at 72.

Yep. I got your code working, too. You can use the index (i) for the artboardRange. Also I've got some code where "exportOptions.quality" is "exportOptions.qualitySetting", not sure which is right.

One more thing: I would not be surprised if exporting as jpg does not set the files "resolution"—I think all it cares about is the pixel dimensions, so use horizontal and vertical scale.

And, as @sttk3 mentioned, the newer exportForScreens is definitely worth looking at.

I looked at the documentation, but don't see how to set the resolution to 300.

The parameters are written in omv.xml, so you can guess how to use them from their names. A sample is here.

var optionsJPEG = new ExportForScreensOptionsJPEG() ;
optionsJPEG.scaleType = ExportForScreensScaleType.SCALEBYRESOLUTION ;
optionsJPEG.scaleTypeValue = 300 ;
