Google图层类 |
| Constants | |
| MAX_ZOOM_LEVEL | {Integer} 最大缩放等级，为21。 |
| MIN_ZOOM_LEVEL | {Integer} 最小缩放等级，为0。 |
| RESOLUTIONS | {Array(Float)} 分辨率数组。 分辨率数组值为固定值，这样会更接近wms的标准投影。 |
| Properties | |
| dpi | {Float} 屏幕上每英寸包含像素点的个数。 该参数结合图层比例尺可以推算出该比例尺下图层的分辨率.默认为96。 |
| sphericalMercator | {Boolean} 是否使用墨卡托投影，默认值为false。 如果使用墨卡托投影，将会导致所有与地图的互动实际上是与地图投影的互动，其支持矢量绘图，地图叠加等。 |
| type | {GMapType} 指定需要获取的图层类型，默认值为unll，表示图层为“G_STREETS_MAP”。 Google服务提供的图层类型有：PHYSICAL、HYBRID、SATELLITE、STREETS。 |
| wrapDateLine | {Boolean} 允许水平方向调整。默认为true。 当<sphericalMercator>为true时，设置此项为false可以限制水平方向调整。 |
| Constructor | |
