indesign script - export selected objects as JPGs - adding extra unwanted padding

[melissa.sones]

hello all - wondering if i can get some help with a script.

script function - export all and only the selected objects on a page as individual JPGs. 

issue - the JPGs keep exporting with extra padding at the top of the box IF there is text close to the top edge. nothing is exceeding the background (example text frame boxes etc) - everything is inside of the grouped background. it is also only happening if there is text next to a top edge - any other edge it does not add any extra padding, hopefully this screenshot will help explain

the script:

(function () {
if (app.documents.length === 0) { alert("Open a document first."); return; }

var doc = app.activeDocument;
if (!doc.selection || doc.selection.length === 0) {
alert("Select the items you want to export, then run the script.");
return;
}

var items = [];
for (var i = 0; i < doc.selection.length; i++) {
var it = doc.selection[i];
if (it.hasOwnProperty("geometricBounds")) items.push(it);
}
if (items.length === 0) { alert("Nothing exportable in the selection."); return; }

items.sort(function(a, b) {
var A = a.geometricBounds, B = b.geometricBounds;
var rowTolerance = 10;
if (Math.abs(A[0] - B[0]) > rowTolerance) {
return A[0] - B[0];
} else {
return A[1] - B[1];
}
});

var outFolder = new Folder('~/Desktop/Export');
if (!outFolder.exists) outFolder.create();

app.jpegExportPreferences.exportResolution = 144;
app.jpegExportPreferences.jpegQuality = JPEGOptionsQuality.MAXIMUM;

var prefix = "FileName_Export-";
function pad2(n){ n = String(n); return n.length < 2 ? "0" + n : n; }

for (var j = 0; j < items.length; j++) {
var filename = prefix + pad2(j + 1) + ".jpg";
var outFile = new File(outFolder.fsName + "/" + filename);
try {
items[j].exportFile(ExportFormat.JPG, outFile, false);
} catch (e) {
$.writeln("Failed to export selected item #" + (j+1) + ": " + e);
}
}

alert("Done! Saved to " + outFolder.fsName);
})();

thank you,

Hi @melissa.sones,

The first thing I would check if I were you was to see if I am able to make it work manually. Only after that would spending time on fixing the script be worth it.

Thanks for this Manan. Exporting as a single selection was doing the same thing, a quick google and someone had suggested trying exporting out of an IDML file and that has fixed the issue.

That is great news @melissa.sones. Over multiple saves the indd files gathers up some corruptions, exporting out to IDML clears out all this. So, if there is something that does not make sense it is a trick worth trying.
