There is a parameter outputFormat to which you can pass any valid output format. You can get the valid formats via:
manager = jpy.get_type(‘org.esa.snap.core.dataio.ProductIOPlugInManager’)
manager.getInstance().getAllProductWriterFormatStrings()
You cannot set the spatial resolution in km. The conversion is pretty simple, though.
