Class ArcBuilder

java.lang.Object

com.lynden.gmapsfx.shapes.ArcBuilder

public class ArcBuilder
extends Object

Builds a Polygon or Polyline in the shape of an Arc. Based on the logic in v3_polygon_exanple_arc.html from http://econym.org.uk/gmap/ which is based in turn on the Latitude/longitude spherical geodesy formulae and scripts at http://www.movable-type.co.uk/scripts/latlong.html (c) Chris Veness 2002-2010

Modifier and Type	Method and Description
static MVCArray	buildArcPoints(LatLong center, double startBearing, double endBearing, double radius) Generates the points for an arc based on two bearings from a centre point and a radius.
static MVCArray	buildArcPoints(LatLong center, LatLong start, LatLong end)
static PolygonOptions	buildClosedArc(LatLong center, LatLong start, LatLong end, javafx.scene.shape.ArcType arcType) Builds the path for a closed arc, returning a PolygonOptions that can be further customised before use.

Method Detail

buildClosedArc

public static final PolygonOptions buildClosedArc(LatLong center,
                                                  LatLong start,
                                                  LatLong end,
                                                  javafx.scene.shape.ArcType arcType)

Builds the path for a closed arc, returning a PolygonOptions that can be further customised before use.

Parameters:

center -

start -

end -

arcType - Pass in either ArcType.CHORD or ArcType.ROUND

Returns:

PolygonOptions with the paths element populated.

buildOpenArc

public static final PolylineOptions buildOpenArc(LatLong center,
                                                 LatLong start,
                                                 LatLong end)

Builds the path for an open arc based on a PolylineOptions.

Parameters:

center -

start -

end -

Returns:

PolylineOptions with the paths element populated.

buildArcPoints

public static final MVCArray buildArcPoints(LatLong center,
                                            LatLong start,
                                            LatLong end)

buildArcPoints

public static final MVCArray buildArcPoints(LatLong center,
                                            double startBearing,
                                            double endBearing,
                                            double radius)

Generates the points for an arc based on two bearings from a centre point and a radius.

Parameters:

center - The LatLong point of the center.

startBearing - North is 0 degrees, East is 90 degrees, etc.

endBearing - North is 0 degrees, East is 90 degrees, etc.

radius - In metres

Returns:

An array of LatLong points in an MVC array representing the arc. Using this method directly you will need to push the centre point onto the array in order to close it, if desired.
