How to Implement a pinch to zoom functionality for TunimImage in mobile?

[merolarosa]

Hi i was wondering how can display multiple images on carousel in mobile with a TUnimImage on each page but with the possibility to zoom the images in and out?

 

i tried many libraries and plugins online but i failed to make them work with unigui mobile.

 

Even if that failed, ow can make zooming mobile form itself enabled like desktop applications?

 

I tried that code but no luck:

<meta content='True' name='HandheldFriendly' />
<meta content='width=device-width; initial-scale=1.0; maximum-scale=2.0; user-scalable=1;' name='viewport' />

if (document.body) {
   document.body.addEventListener('touchmove',function(event){
  event.preventDefault();
   },false);
}

Please help me in either zoom the whole window or image.

 

Thanks in advance
