请问MapContext.addGroundOverlay创建的自定义图层怎么遮住地图poi?
this.mapCtx.addGroundOverlay({ id: 10086, src: '/image/map.png', bounds: { southwest: { //西南角经纬度 latitude: 22.57752841911238, longitude: 114.04844556792409 }, northeast: { //东北角经纬度 latitude: 22.81703829138907, longitude: 114.36735410533367 } }, success: res => { console.log(res, "图层创建成功"); }, fail: err => { console.log(err, "图层创建错误"); }
