NAME

Geo::Geos::Algorithm::MinimumDiameter - Computes the minimum diameter of a Geometry

SYNOPSIS

    use Geo::Geos::Coordinate;
    use Geo::Geos::GeometryFactory;
    use Geo::Geos::Algorithm::MinimumDiameter qw/getMinimumRectangle/;

    my $c1 = Geo::Geos::Coordinate->new(1,2);
    my $c2 = Geo::Geos::Coordinate->new(5,2);
    my $c3 = Geo::Geos::Coordinate->new(5,0);
    my $c4 = Geo::Geos::Coordinate->new(1,0);
    my $gf = Geo::Geos::GeometryFactory::create();

    my $lr = $gf->createLinearRing([$c1, $c2, $c3, $c4, $c1], 2);
    my $md1 = Geo::Geos::Algorithm::MinimumDiameter->new($lr);

    my $md2 = Geo::Geos::Algorithm::MinimumDiameter->new($lr, 1);

    $md2->getLength;                # => is 2
    $md2->getWidthCoordinate;       # => is Geo::Geos::Coordinate->new(1,0)

    my $ls = $gf->createLineString([$c1, $c2], 2);
    my $ss = $md2->getSupportingSegment;    # => isa 'Geo::Geos::Geometry'
    $ls->equalsExact($ss);                  # => success

    my $d = $md2->getDiameter;      # => isa 'Geo::Geos::Geometry'
    $d->toString;                   # => is 'LINESTRING (1.0000000000000000 2.0000000000000000, 1.0000000000000000 0.0000000000000000)'

    my $r = $md2->getMinimumRectangle;      # => isa 'Geo::Geos::Geometry'
    $r->toString;                           # like qr/POLYGON/;

    getMinimumRectangle($ls);               # => isa 'Geo::Geos::Geometry'
