NAME

Geo::Geos::WKBWriter - Writes a Geometry into Well-Known Binary format.

SYNOPSIS

    use Geo::Geos::GeometryFactory;
    use Geo::Geos::PrecisionModel qw/TYPE_FLOATING/;
    use Geo::Geos::WKBWriter;
    use Geo::Geos::WKBConstants qw/TYPE_BYTEORDER_BE/;

    my $pm = Geo::Geos::PrecisionModel->new(TYPE_FLOATING);
    my $gf = Geo::Geos::GeometryFactory::create($pm, 3857);
    my $c  = Geo::Geos::Coordinate->new(1,2);
    my $p  = $gf->createPoint($c);

    my $dimensions   = 2;
    my $include_SRID = 1;

    Geo::Geos::WKBWriter->new($dimensions, TYPE_BYTEORDER_BE, $include_SRID);    # => isa 'Geo::Geos::WKBWriter'
    Geo::Geos::WKBWriter->new($dimensions, TYPE_BYTEORDER_BE);                   # => isa 'Geo::Geos::WKBWriter'
    Geo::Geos::WKBWriter->new($dimensions);                                      # => isa 'Geo::Geos::WKBWriter'
    Geo::Geos::WKBWriter->new();                                                 # => isa 'Geo::Geos::WKBWriter'

    my $w = Geo::Geos::WKBWriter->new($dimensions, TYPE_BYTEORDER_BE, $include_SRID);

    $w->setOutputDimension(2);
