Export to PNG in InDesign?

Where's y'all imagination?

This is a Quick-and-So-Very-Dirty-Dirty-Dirty javascript with lots of traps and pitfalls; still, it works as a Proof Of Concept to do the dirty thang straight out of InDesign.

(In particular I cannot stress enough: Do Not Use On Your Live Document. Save a copy first, because this script messes up your document, and if good old trusty InDesign chooses to crash while running the script, this Messed Up Version will be saved as "current one"!!)

//DESCRIPTION:Export all pages to PNGs -- Do Not Use For Production Purposes
// A Move Along, Nothing to See Here Production
for (pg=0; pg<app.activeDocument.pages.length; pg++)
{
     page = app.activeDocument.pages[pg];
     for (mas=0; mas < page.appliedMaster.pageItems.length; mas++)
          try {
               page.appliedMaster.pageItems[mas].override(app.activeDocument.pages[pg]);
          } catch (bah) { }
     g = page.groups.add(page.pageItems);
     g.exportFile(ExportFormat.PNG_FORMAT, File(Folder.myDocuments.fsName+"/"+(page.name)+".png"));
}
