static bool getCentroid (const geom::Geometry &geom, geom::Coordinate &cent)

Detailed Description

Computes the centroid of a Geometry of any dimension. If the geometry is nomimally of higher dimension, but contains only components having a lower effective dimension (i.e. zero length or area), the centroid will be computed appropriately.

Algorithm

If the input geometries are empty, a null Coordinate is returned.


Constructor & Destructor Documentation

Creates a new instance for computing the centroid of a geometry


Member Function Documentation

static bool geos::algorithm::Centroid::getCentroid ( const geom::Geometry geom,
geom::Coordinate cent 
) [static]

Computes the centroid point of a geometry.

Parameters:
geomthe geometry to use
centwill be set to the centroid point, if any
Returns:
true if a centroid could be computed, false otherwise (empty geom)

Gets the computed centroid.

Parameters:
centwill be set to the centroid point, if any
Returns:
true if a centroid could be computed, false otherwise (empty geom)
