Hi,
Guess you mean in mobile. You can use the ONRESIZE , call/code there an action that compares STAGEHEIGHT with STAGEWIDTH (if(stageheight LT stageheight, ...) then you can specify it to vanish GUI and show a rotate icon layer when width is slower than height.
That should do it.
Best
Really thanks for your reply.
I am pretty new to Krpano it be really helpfull if, you give complete exact code.
Thnaks in advance
