assembleInteriorAttributes

public static ShapeAttributes assembleInteriorAttributes(ShapeAttributes attrs,
                                                         KMLPolyStyle style)

assembleLineAttributes

public static ShapeAttributes assembleLineAttributes(ShapeAttributes attrs,
                                                     KMLLineStyle style)

computeAltitude

public static List<Position> computeAltitude(Globe globe,
                                             List<? extends Position> positions,
                                             String altitudeMode)

Compute the altitude of each position in a list, based on altitude mode.

Parameters:

globe - Globe to use to determine altitude above terrain.

positions - Positions to compute altitude for.

altitudeMode - A KML altitude mode string.

Returns:

A new list of positions with altitudes set based on altitudeMode.

computeAltitude

public static Position computeAltitude(Globe globe,
                                       Position position,
                                       String altitudeMode)

Create a Position, taking into account an altitude mode.

Parameters:

globe - Globe to use to determine altitude above terrain.

position - Position to evaluate.

altitudeMode - A KML altitude mode string.

Returns:

New Position.

convertAltitudeMode

public static int convertAltitudeMode(String altMode,
                                      int defaultAltMode)

createSectorFromLatLonBox

public static Sector createSectorFromLatLonBox(KMLAbstractLatLonBoxType box)

Creates a Sector from a KMLAbstractLatLonBoxType's north, south, east, and west coordinates. This returns null if any of these coordinates are unspecified.

Parameters:

box - a box who's coordinates define a Sector.

Returns:

the Sector that bounds the specified box's coordinates.

Throws:

IllegalArgumentException - if the box is null.

getPositions

public static void getPositions(Globe globe,
                                KMLAbstractGeometry geometry,
                                List<Position> positions)

Get all of the positions that make up a KMLAbstractGeometry. If the geometry contains other geometries, this method collects all the points from all of the geometries.

Parameters:

globe - Globe to use to determine altitude above terrain.

geometry - Geometry to collect positions from.

positions - Placemark positions will be added to this list.

isHighlightStyleState

public static boolean isHighlightStyleState(KMLAbstractSubStyle subStyle)

Indicate whether a specified sub-style has the "highlight" style-state field.

Parameters:

subStyle - the sub-style to test. May be null, in which case this method returns false.

Returns:

true if the sub-style has the "highlight" field, otherwise false.

kmlUnitsToWWUnits

public static String kmlUnitsToWWUnits(String units)

Translate a KML units string ("pixels", "insetPixels", or "fraction") into the corresponding WW unit constant (AVKey.PIXELS, AVKey.INSET_PIXELS, or AVKey.FRACTION.

Parameters:

units - KML units to translate.

Returns:

WW units, or null if the argument is not a valid KML unit.

rotateSector

public static List<LatLon> rotateSector(Globe globe,
                                        Sector sector,
                                        Angle rotation)

Rotate the corners of a sector around a normal vector through the sector centroid.

Parameters:

globe - Globe to use to compute rotated positions.

sector - Sector to rotate.

rotation - Rotation angle. Positive angles produce counterclockwise rotation.

Returns:

List of rotated corners.

wwUnitsToKMLUnits

public static String wwUnitsToKMLUnits(String units)

Translate a WorldWind units constant (AVKey.PIXELS, AVKey.INSET_PIXELS, or AVKey.FRACTION to the corresponding KML unit string ("pixels", "insetPixels", or "fraction").

Parameters:

units - World Wind units to translate.

Returns:

KML units, or null if the argument is not a valid WW unit.
