如何使用ngx-leaflet(Angular方式)创建矢量切片贴图？

>通过yarn add leaflet.vectorgrid安装它
>创建定义要使用的API的binding file src / typings / leaflet.vectorgrid.d.ts,例如：

import * as L from "leaflet";

declare module "leaflet" {
  namespace vectorGrid {
    export function slicer(data: any,options?: any): any;
  }
}

>加载矢量切片,例如：

// add import statement
import * as L from "leaflet";
// then call...
loadGeojson() {
    this.http.get("assets/airports.min.geojson").subscribe(result => {
            this.vtLayer = l.vectorGrid.slicer(result,{
              zIndex: 1000
            });
            this.vtLayer.addTo(this.map);
    });
}
