I'm trying to use marcator projection with custom map and when I run
it I get the following JS error:
d[Ab] is not a function (main.js line 40).
anybody can find the problem?
var MERCATOR_RANGE = 256;
function bound(value, opt_min, opt_max) {
if (opt_min != null) value = Math.max(value, opt_min);
if (opt_max != null) value = Math.min(value, opt_max);
return value;
}
function degreesToRadians(deg) {
return deg * (Math.PI / 180);
}
function radiansToDegrees(rad) {
return rad / (Math.PI / 180);
}
function MercatorProjection() {
this.pixelOrigin_ = new google.maps.Point(MERCATOR_RANGE / 2,
MERCATOR_RANGE / 2);
this.pixelsPerLonDegree_ = MERCATOR_RANGE / 360;
this.pixelsPerLonRadian_ = MERCATOR_RANGE / (2 * Math.PI);
};
MercatorProjection.prototype.fromLatLngToPoint = function(latLng,
opt_point) {
var me = this;
var point = opt_point || new google.maps.Point(0, 0);
var origin = me.pixelOrigin_;
point.x = Math.round(origin.x + latLng.lng() *
me.pixelsPerLonDegree_);
// NOTE(appleton): Truncating to 0.9999 effectively limits
latitude to
// 89.189. This is about a third of a tile past the edge of the
world tile.
var siny = bound(Math.sin(degreesToRadians(latLng.lat())),
-0.9999, 0.9999);
point.y = Math.round(origin.y + 0.5 * Math.log((1 + siny) / (1 -
siny)) * -me.pixelsPerLonRadian_);
return point;
};
MercatorProjection.prototype.fromPointToLatLng = function(point) {
var me = this;
var origin = me.pixelOrigin_;
var lng = (point.x - origin.x) / me.pixelsPerLonDegree_;
var latRadians = (point.y - origin.y) / -me.pixelsPerLonRadian_;
var lat = radiansToDegrees(2 * Math.atan(Math.exp(latRadians)) -
Math.PI / 2);
return new google.maps.LatLng(lat, lng);
};
function initialize() {
var latlng = new google.maps.LatLng(44,3);
var MyMapType = new google.maps.ImageMapType({
getTitleUrl: function(coord, zoom) {
return "http://vec.maps.yandex.net/tiles?l=map&v=2.14.0&x=";
+ coord.x +"&y=" + coord.y +"&z=" + zoom;
},
tileSize: new google.maps.Size(256,256),
isPng: true,
minZoom: 0,
maxZoom: 17,
name: 'MyMap'
});
MyMapType.projection = new MercatorProjection();
var myOptions ={
zoom: 8,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new
google.maps.Map(document.getElementById("map_canvas"), myOptions);
map.mapTypes.set('myMap', MyMapType);
map.setMapTypeId('myMap');
}
