顶级类 ShapeCreator ShapeCreator 提供图形构建,返回线条图形LineShape或面图形PolygonShape

ShapeCreator(points:点集合,type:图形类型,size:可选边数量)：LineShape|PolygonShape

import {ShapeCreator } from "@violets/shape"
import { Feature, Map, MapBrowserEvent } from "ol";
export class Draw{

  Creator(){
    let shape= ShapeCreator(this.points,this.type,this.size);
    let feature= new Feature(shape);
    this.featureSource.addFeature(feature);
  }
