* @param {Boolean} [option.cache = false] 是否使用动态裁图功能
* @param {Number} [option.level = 0] 动态裁图的级数
* @param {Number} [option.row = 0] 行号
* @param {Number} [option.col = 0] 列号
* @param {Boolean} [option.update = false] 是否更新当前瓦片
* @param {String} [option.layers = null] 该参数,当cache为true时无效(仅在非动态裁图时有意义)
* @param {Zondy.Object.CDisplayStyle} [option.style = null] 图文档显示样式,该参数,当cache为true时无效(仅在非动态裁图时有意义)
* @param {String} [option.picType = gif] 图片的格式 jpg|png|gif。该参数,当cache为true时无效(仅在非动态裁图时有意义)
* @param {String} [option.bbox = null] 图片的范围xmin,ymin,xmax,ymax。该参数,当cache为true时无效(仅在非动态裁图时有意义)
