expand

public static org.locationtech.jts.geom.Geometry expand(org.locationtech.jts.geom.Geometry geometry,
                                                        double delta)

Expands a geometry's envelope by the given delta X and delta Y. Both positive and negative distances are supported.

Parameters:

geometry - the input geometry

delta - the distance to expand the envelope along the X and Y axis

Returns:

the expanded geometry
