Constructor Detail

Bounds

protected Bounds(JSObject element)

Bounds

public Bounds(double lowerLeftX,
              double lowerLeftY,
              double upperRightX,
              double upperRightY)

Create a bounding box by specifying its lower left coordinates, and its upper right coordinates. The units of the bounding box will depend on the CRS and or projection used. For example, a bounds object that represents the world-wide bounds in EPSG:4392 is specified as: new Bounds(-180,-90,180,90);

Parameters:

lowerLeftX - = west = minx

lowerLeftY - = south = miny

upperRightX - = east = maxx

upperRightY - = north = maxy

Method Detail

narrowToBounds

public static Bounds narrowToBounds(JSObject element)

toArray

public double[] toArray()

getLowerLeftX

public double getLowerLeftX()

Returns:

double - lower left x-coordinate of bounds

getLowerLeftY

public double getLowerLeftY()

Returns:

double - lower left y-coordinate of bounds

getUpperRightX

public double getUpperRightX()

Returns:

double - upper right x-coordinate of bounds

getUpperRightY

public double getUpperRightY()

Returns:

double - upper right y-coordinate of bounds

getWidth

public float getWidth()

getHeight

public float getHeight()

toBBox

public String toBBox(Integer significantDigits)

Parameters:

significantDigits - - Number of significant digits in the bbox coordinates, pass null to use the default of 6.

Returns:

String - simple string representation of a Bounds object. For example: "5,42,10,45"

containsLonLat

public boolean containsLonLat(LonLat ll,
                              boolean inclusive)

APIMethod: containsLonLat Parameters: ll - {} inclusive - {Boolean} Whether or not to include the border. Default is true. Returns: {Boolean} The passed-in lonlat is within this bounds.
