  • Yes. Just put the image in a scrollview. Like below. You can adjust the scale with the scrollview minZoom and maxZoom. 

    var win = Ti.UI.createWindow({
    backgroundColor : '#000',
});
 
var scrollView = Ti.UI.createScrollView({
    backgroundColor: 'yellow',
    width: 320,
    height: 460,
    contentWidth:'auto',
    contentHeight:'auto',
   // showHorizontalScrollIndicator: true,
    //showVerticalScrollIndicator:true,
    minZoomScale:1,  
    maxZoomScale:10, 
    zoomScale:1,
    top:0
});
 
 
 
scrollView.addEventListener('scale', function (){
    Ti.API.debug(scrollView.zoomScale)
});
 
 
var image = Ti.UI.createView({
    backgroundColor: 'red',
    width: 320,
    height: 320,
});
 
 
 
scrollView.add(image);
 
win.add(scrollView);
 
win.open()
