使用Angular google maps (AGM)获取地图的NorthWest和SouthEast

import { Component } from '@angular/core';
import { LatLngBounds, MapBoundsLiteral } from '@agm/core';

@Component({
  selector: 'app-map',
  templateUrl: './map.component.html',
  styleUrls: ['./map.component.css']
})
export class MapComponent {
  bounds: LatLngBounds;

  onMapBoundsChange(bounds: MapBoundsLiteral) {
    this.bounds = bounds;
    // 在这里可以获取到北西角和东南角的经纬度坐标，并进行相应的操作
    console.log('NorthWest:', this.bounds.north, this.bounds.west);
    console.log('SouthEast:', this.bounds.south, this.bounds.east);
  }
}

<agm-map (boundsChange)="onMapBoundsChange($event)">
  <!-- 在这里添加其他地图相关的组件或标记 -->
</agm-map>
