Overview

Create one GroundOverlay

var bounds = [
  {"lat": 40.712216, "lng": -74.22655},
  {"lat": 40.773941, "lng": -74.12544}
];
var mapDiv = document.getElementById("map_canvas");
var map = plugin.google.maps.Map.getMap(mapDiv, {
  camera: {
    target: bounds
  }
});

// Add ground overlay
var groundOverlay = map.addGroundOverlay({
  'url': "../images/newark_nj_1922.jpg",
  'bounds': bounds,
  'opacity': 0.5
});

Listen CLICK event

In order to listen the GROUND_OVERLAY_CLICK event, you need to specify the clickable option. You can get the latitude/longitude pair of clicked position.

var bounds = [
  {"lat": 40.712216, "lng": -74.22655},
  {"lat": 40.773941, "lng": -74.12544}
];

// Add ground overlay
var groundOverlay = map.addGroundOverlay({
  'url': "../images/newark_nj_1922.jpg",
  'bounds': bounds,
  'opacity': 0.5,
  'clickable': true  // default = false
});

// Catch the GROUND_OVERLAY_CLICK event
groundOverlay.on(plugin.google.maps.event.GROUND_OVERLAY_CLICK, function (latLng) {
  ...
});
