Reduced test case:

   var win = Ti.UI.createWindow({ fullscreen: true, backgroundColor: 'white'});
        
   	var view = Ti.UI.createScrollView({
   		backgroundColor:'#000',
   		borderRadius:150,
   		height:300,
   		width:300,
   		contentHeight:'auto',
   		contentWidth:'auto',
   		minZoomScale:0.05,
   		maxZoomScale:3.0,
   		zoomScle:1.0
   	});
   	
   	var image = Ti.UI.createImageView({
   		image:'beach.jpg',
   		height:'auto',
   		width:'auto'
   	});
   	view.add(image);
   	win.add(view);
           win.open();
