I can't run a debugger on the code you posted. Where is your map that exhibits the problem? http://groups.google.com/group/google-maps-js-api-v3/browse_frm/thread/2b3f101fd509919e?hl=en -- Larry > > 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.
