I have set up a map application using ArcGIS JavaScript API v3.16 and included functionality for exporting a map to PDF using the PrintTask. Is there a way that I can use a button/checkbox to turn on an extent box to show on the map application of what portion of the map will show up on the export map output? I have the PrintTask set up to preserve map scale - so extent is not preserved. Usually the output of the PrintTask is less of an extent than that of the map application so I would like to let users be able to know what will be printed.

  • Take a look at this discussion on GeoNet that contains code to put in an extent box for the print output: geonet.esri.com/thread/174090
