   if (typeof DocuViewareAPI !== "undefined" && DocuViewareAPI.IsInitialized("DocuVieware1")) {
      DocuViewareAPI.RegisterOnAreaSelected("DocuVieware1", function (annot) {
         console.log(DocuViewareAPI.GetSelectionAreaCoordinates("DocuVieware1"));
      });
   }
   else {
      setTimeout(function () { RegisterOnAreaSelectedOnDocuViewareAPIReady() }, 10);
   }
}
window.onload = function () {
   RegisterOnAreaSelectedOnDocuViewareAPIReady();
}
