Titanium TableView

titanium ImageView

  // create another variable , self
var self = Ti.UI.currentWindow;
var view = Ti.UI.createView();


var imageView = Ti.UI.createImageView(
{
image:'/images/screenshot_AVD.png',
enableZoomControls:false,
width:'auto',
height:'auto'
}
);
imageView.addEventListener("load", function(e){
Ti.API.info("image loaded");
Ti.API.info("size: " + imageView.size.width + ", " + imageView.size.height);
}

);
var scrollView = Ti.UI.createScrollView(
{
//contentWidth: 'auto',
 //contentHeight: 'auto',
 showVerticalScrollIndicator: true,
 showHorizontalScrollIndicator: true,
 height: '80%',
 width: '80%'
 //zoomScale:2,
 //minZoomScale:1,
 //maxZoomScale:7
}
);

var originalWidth = -1;
var originalHeight = -1;
var scale = 1;

scrollView.addEventListener("touchend", function(e){
Ti.API.info("touchend");

originalWidth *= scale;
originalHeight *= scale;
});

scrollView.addEventListener("pinch", function(e){
Ti.API.info("pinch: " + e.scale);
//scrollView.zoomScale = e.scale;
if(originalWidth < 0){
Ti.API.info("size: " + imageView.size.width + ", " + imageView.size.height);
originalWidth = imageView.size.width;
originalHeight = imageView.size.height;
}
imageView.width = e.scale * originalWidth;
imageView.height = e.scale * originalHeight;
scale = e.scale;
//scrollView.contentWidth *= e.scale ;
//scrollView.contentHeight *= e.scale;
})

scrollView.add(imageView);
self.add(scrollView);

not fool proof for zooming. scrollbar not showing properly
may be better to use the transform matrix, eg. scale
