polygon_smooth library

Smooths the outline of a Polygon using Chaikin's algorithm.

Classes

BBox
Please make sure, you arrange your parameters like this: Longitude 1, Latitude 1, Altitude 1 (optional), Longitude 2, Latitude 2, Altitude 2 (optional) You can either specify 4 or 6 parameters If you are using the default constructor with two dimensional positions (lng + lat only), please use the constructor like this: BBox(lng1, lat1, lng2, lat2);

Functions

polygonSmooth(GeoJSONObject inputPolys, {int iterations = 1}) → FeatureCollection<GeometryObject>
Smooths a Polygon, MultiPolygon, also inside Features, FeatureCollections, or GeometryCollection. Based on Chaikin's algorithm. Warning: may create degenerate polygons. The optional parameter iterations is the number of times to smooth the polygon. A higher value means a smoother polygon. The functions returns a FeatureCollection of Polygons and MultiPolygons.
