我對Google Maps API v2相當陌生，並且希望通過以下基本鏈接集成地圖：https://tiles.guildwars2.com/{continent_id}/{floor}/{zoom}/{x}/{y}.jpg。我的問題是，以及一切，但讓我們開始以下幾點：在Google地圖中使用自定義貼圖
1）如何設置地圖大小，在任何一邊都沒有灰色空間？ 
2）我如何正確移動地圖，因爲我明顯有4個參數，而我一次只能用getTileUrl更改3個參數？ 3）爲什麼瓷磚混合，沒有按正確的順序顯示？

你能展示一個正確的URL的工作示例嗎？你能詳細說明一下：「我怎樣才能設置地圖大小，任何一邊都沒有灰色空間？」？ – antonio
