I tryed it, and if I do not display the scroll bar of the ScrolledWindow 
the minimum size of the container will be
exactly the size request of the parent. here below there is the code I used.

int main (int argc, char *argv[])
{
   Gtk::Main lKit (argc, argv);

   Gtk::Window lWindow;
   Gtk::Image lImage ("supine_partialvolume.png");
   Gtk::ScrolledWindow lSW;
   lWindow.add (lSW);
   lSW.add (lImage);
   lSW.set_policy (Gtk::POLICY_NEVER, Gtk::POLICY_NEVER);
   lWindow.show_all_children ();

   lKit.run (lWindow);
   return 0;
}
