Adobe DPS Reading SDK: how to get currently displaying page orientation?

Question

Hi All,
I've been trying to extract page/article information using the Adobe DPS Reading SDK.
There is a tutorial (New APIs and features in r30, including folio navigation, article metadata and calendar events | Adobe Developer Connect…) which i've heavily reused but there is on last thing in the puzzle that I need to extract.
I need to extract the page layout / orientation when displayed on a device.
adobeDPS.folioDataService only extract article metadata and those methods do not contain any reference to orientation or layout.
Interesting enough, i was able to locate a "ApplicationState" object which is produced from the ConfigurationService.( Adobe DPS - Reading SDK 2.30 : adobeDPS-ConfigurationService : JsDoc Reference )
I haven't try this the "orientation" field description is not exactly what i want: "The orientations this view supports."
I need the:  orientation which i'm currently displaying this page.
Any thoughts? Should i be using a different SDK?
Your help is very appreciated.
Regards

You can use the javascript native attribute "window.orientation".
Something like this should work:
    function currentOrientation(){
          switch(Math.abs(window.orientation)){
               case 90:
                     alert('landscape');
                     break;
               default:
                    alert('portrait');
                    break;
window.addEventListener('orientationchange' , function(){ currentOrientation() });
//Call it first if needed
currentOrientation();
