public class Envelope2DArchived extends Rectangle2D.Double implements BoundingBox, Bounds, Cloneable
A two-dimensional envelope on top ofRectangle2D
. This implementation is provided for interoperability between Java2D and GeoAPI.Note: This class inherits x and y fields. But despite their names, they don't need to be oriented toward East and North respectively. The (x,y) axis can have any orientation and should be understood as "ordinate 0" and "ordinate 1" values instead. This is not specific to this implementation; in Java2D too, the visual axis orientation depend on the affine transform in the graphics context.

intersects
public boolean intersects(BoundingBox bounds)
Returnstrue
if the interior of this bounds intersects the interior of the provided bounds.Note this method conflicts with

toBounds
public BoundingBox toBounds(CoordinateReferenceSystem targetCRS) throws TransformException
Description copied from interface:BoundingBox
Transforms this box to the specified CRS and returns a new bounding box for the transformed shape. This method provides a convenient (while not always efficient) way to get minimum and maximum ordinate values toward some specific axis directions, typically East and North.Example: if
box
is a bounding box using a geographic CRS with WGS84 datum, then one can write:GeographicCRS targetCRS = crsAuthorityFactory.createGeographicCRS("EPSG:4326"); BoundingBox targetBox = box.toBounds(targetCRS); double minEasting = targetBox.getMinY(); double minNorthing = targetBox.getMinX();
"EPSG:4326"
has (latitude, longitude) axis order, thus the inversion of X and Y in the above code.Sophesticated applications will typically provide more efficient way to perform similar transformations in their context. For example Canvas store precomputed objective to display transforms.
- Specified by:
toBounds
in interfaceBoundingBox
- Parameters:
targetCRS
- The target CRS for the bounding box to be returned.- Returns:
- A new bounding box wich includes the shape of this box transformed to the specified target CRS.
- Throws:
TransformException
- if no transformation path has been found from this box CRS to the specified target CRS, or if the transformation failed for an other reason.
