- Parameters:
-
bounds
: -
{H.geo.Rect}
- A rectangle defining the bounds for the rectangle
getGeometry () : {(H.geo.Polygon | H.geo.MultiPolygon)}
To obtain the polygon's geometry. If you modify the obtained geometry, you must call setGeometry
afterwards to not violate the integrity of the polygon.
- Returns:
-
{(H.geo.Polygon | H.geo.MultiPolygon)}
setGeometry (geometry) : {H.map.Polygon}
To set the polygon's geometry. If the given geometry is modified afterwards, it must be set via setGeometry
again to not violate the integrity of the polygon.
- Parameters:

{(H.geo.Polygon | H.geo.MultiPolygon)}
- Returns:
-
{H.map.Polygon}
setNorthPoleCovering (flag) : {H.map.Polygon}
To specify whether this polygon covers the North or the South Pole. This information is only needed for very special Polygons whose geometry is defined as a line string around the world on longitude axis (for example along the coast of the Antarctic). In such cases, an additional information is needed to know if the southern part (Antarctic) or the northern part (anything except Antarctic) should be covered.
