com.dlsc.gmapsfx.javascript.object.LatLong, .MVCArray, javafx.scene.shape.ArcType
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 TypeMethod and Description
public static final MVCArray
buildArcPoints(LatLong center, LatLong start, LatLong end)

public static final MVCArray

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.
buildArcPoints(LatLong
The LatLong point of the center.
center, double
North is 0 degrees, East is 90 degrees, etc.
startBearing, double
North is 0 degrees, East is 90 degrees, etc.
endBearing, double
In metres
radius)

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

public static final PolygonOptions

Returns:

PolygonOptions with the paths element populated.
buildClosedArc(LatLong center, LatLong start, LatLong end, ArcType
Pass in either ArcType.CHORD or ArcType.ROUND
arcType)

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

public static final PolylineOptions

Returns:

PolylineOptions with the paths element populated.
buildOpenArc(LatLong center, LatLong start, LatLong end)

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