Class 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.

      • 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
