Function polygonSmooth

polygonSmooth(polygon, options?): FeatureCollection<Polygon, {
[name: string]: any;
}>
Chaikin's algorithm을 적용한, 굴곡진 다각형을 생성하는 함수입니다.
Parameters
- polygon: FeatureCollection<Geometry, {
  [name: string]: any;
  }> | Feature<Polygon | MultiPolygon, {
  [name: string]: any;
  }> | Polygon | MultiPolygon
  Chaikin's algorithm을 적용할 Polygon 입니다.
- Optional options: {
  iterations?: number;
  }
  polygonSmooth 함수에서 사용할 옵션입니다.
  - Optional iterations?: number
    해당값이 높을수록 더 굴곡진 Polygon이 반환됩니다.
    Default
    1
Returns FeatureCollection<Polygon, {
[name: string]: any;
}>
굴곡진 다각형이 포함된 Polygon FeatureCollection이 반환됩니다.
Example
```
const polygon: ktGms.geometry.Polygon = new ktGms.geometry.Polygon(
   [
     [
       [127.015522, 37.49044],
       [127.02222, 37.49044],
       [127.02222, 37.49294],
       [127.015522, 37.49294],
       [127.015522, 37.49044],
     ],
   ],
   {}
 );
 const smoothed = analysis.transformation.polygonSmooth(polygon);
