Class CentroidArea

java.lang.Object

com.vividsolutions.jts.algorithm.CentroidArea

Deprecated.

use Centroid instead

public class CentroidArea
extends Object

Computes the centroid of an area geometry.

Algorithm

Based on the usual algorithm for calculating the centroid as a weighted sum of the centroids of a decomposition of the area into (possibly overlapping) triangles. The algorithm has been extended to handle holes and multi-polygons. See http://www.faqs.org/faqs/graphics/algorithms-faq/ for further details of the basic approach. The code has also be extended to handle degenerate (zero-area) polygons. In this case, the centroid of the line segments in the polygon will be returned.

Method Detail

add

public void add(Geometry geom)

Deprecated.

Adds the area defined by a Geometry to the centroid total. If the geometry has no area it does not contribute to the centroid.

Parameters:

geom - the geometry to add

add

public void add(Coordinate[] ring)

Deprecated.

Adds the area defined by an array of coordinates. The array must be a ring; i.e. end with the same coordinate as it starts with.

Parameters:

ring - an array of Coordinates

getCentroid

public Coordinate getCentroid()

Deprecated.
