Class DefaultImageCRS

All Implemented Interfaces:
Serializable, Formattable, Deprecable, LenientComparable, org.opengis.referencing.crs.CoordinateReferenceSystem, org.opengis.referencing.crs.ImageCRS, org.opengis.referencing.crs.SingleCRS, org.opengis.referencing.IdentifiedObject, org.opengis.referencing.ReferenceSystem

public class DefaultImageCRS extends AbstractCRS implements org.opengis.referencing.crs.ImageCRS
A 2-dimensional engineering coordinate reference system applied to locations in images. Image coordinate reference systems are treated as a separate sub-type because a separate user community exists for images with its own terms of reference.

Used with datum type: Image.
Used with coordinate system types: Cartesian or Affine.

Immutability and thread safety

This class is immutable and thus thread-safe if the property values (not necessarily the map itself), the coordinate system and the datum instances given to the constructor are also immutable. Unless otherwise noted in the javadoc, this condition holds if all components were created using only SIS factories and static constants.

    • DefaultImageCRS

      public DefaultImageCRS(Map<String,?> properties, org.opengis.referencing.datum.ImageDatum datum, org.opengis.referencing.cs.AffineCS cs)
      Creates a coordinate reference system from the given properties, datum and coordinate system. The properties given in argument follow the same rules than for the super-class constructor. The following table is a reminder of main (not all) properties:
      Recognized properties (non exhaustive list)
      Property name Value type Returned by
      "name" ReferenceIdentifier or String AbstractIdentifiedObject.getName()
      "alias" GenericName or CharSequence (optionally as array) AbstractIdentifiedObject.getAlias()
      "identifiers" ReferenceIdentifier (optionally as array) AbstractIdentifiedObject.getIdentifiers()
      "remarks" InternationalString or String AbstractIdentifiedObject.getRemarks()
      "domainOfValidity" Extent AbstractReferenceSystem.getDomainOfValidity()
      "scope" InternationalString or String AbstractReferenceSystem.getScope()
      Parameters:
      properties - the properties to be given to the coordinate reference system.
      datum - the datum.
      cs - the coordinate system.

    • DefaultImageCRS

      protected DefaultImageCRS(org.opengis.referencing.crs.ImageCRS crs)
      Constructs a new coordinate reference system with the same values than the specified one. This copy constructor provides a way to convert an arbitrary implementation into a SIS one or a user-defined one (as a subclass), usually in order to leverage some implementation-specific API.

      This constructor performs a shallow copy, i.e. the properties are not cloned.

      Parameters:
      crs - the coordinate reference system to copy.
      See Also:
    • DefaultImageCRS

      private DefaultImageCRS()
      Constructs a new object in which every attributes are set to a null value. This is not a valid object. This constructor is strictly reserved to JAXB, which will assign values to the fields using reflection.
  • Method Details

    • castOrCopy

      public static DefaultImageCRS castOrCopy(org.opengis.referencing.crs.ImageCRS object)
      Returns a SIS coordinate reference system implementation with the same values than the given arbitrary implementation. If the given object is null, then this method returns null. Otherwise if the given object is already a SIS implementation, then the given object is returned unchanged. Otherwise a new SIS implementation is created and initialized to the attribute values of the given object.
      Parameters:
      object - the object to get as a SIS implementation, or null if none.
      Returns:
      a SIS implementation containing the values of the given object (may be the given object itself), or null if the argument was null.
    • getInterface

      public Class<? extends org.opengis.referencing.crs.ImageCRS> getInterface()
      Returns the GeoAPI interface implemented by this class. The SIS implementation returns ImageCRS.class.
      Note for implementers: Subclasses usually do not need to override this method since GeoAPI does not define ImageCRS sub-interface. Overriding possibility is left mostly for implementers who wish to extend GeoAPI with their own set of interfaces.
      Overrides:
      getInterface in class AbstractCRS
      Returns:
      ImageCRS.class or a user-defined sub-interface.
    • getDatum

      public org.opengis.referencing.datum.ImageDatum getDatum()
      Returns the datum.
      Specified by:
      getDatum in interface org.opengis.referencing.crs.ImageCRS
      Specified by:
      getDatum in interface org.opengis.referencing.crs.SingleCRS
      Overrides:
      getDatum in class AbstractCRS
      Returns:
      the datum.
    • getCoordinateSystem

      public org.opengis.referencing.cs.AffineCS getCoordinateSystem()
      Returns the coordinate system.
      Specified by:
      getCoordinateSystem in interface org.opengis.referencing.crs.CoordinateReferenceSystem
      Specified by:
      getCoordinateSystem in interface org.opengis.referencing.crs.ImageCRS
      Specified by:
      getCoordinateSystem in interface org.opengis.referencing.crs.SingleCRS
      Overrides:
      getCoordinateSystem in class AbstractCRS
      Returns:
      the coordinate system.
    • forConvention

      public DefaultImageCRS forConvention(AxesConvention convention)
      Returns a coordinate reference system equivalent to this one but with axes rearranged according the given convention. If this CRS is already compatible with the given convention, then this method returns this.
      Overrides:
      forConvention in class AbstractCRS
      Parameters:
      convention - the axes convention for which a coordinate reference system is desired.
      Returns:
      a coordinate reference system compatible with the given convention (may be this).
      See Also:
    • createSameType

      final AbstractCRS createSameType(Map<String,?> properties, org.opengis.referencing.cs.CoordinateSystem cs)
      Returns a coordinate reference system of the same type than this CRS but with different axes.
      Overrides:
      createSameType in class AbstractCRS
    • formatTo

      protected String formatTo(Formatter formatter)
      Formats this CRS as a Well Known Text ImageCRS[…] element.
      Compatibility note: ImageCRS are defined in the WKT 2 specification only.
      Overrides:
      formatTo in class AbstractCRS
      Parameters:
      formatter - the formatter where to format the inner content of this WKT element.
      Returns:
      "ImageCRS".

    • setDatum

      private void setDatum(org.opengis.referencing.datum.ImageDatum value)
      Invoked by JAXB at unmarshalling time.
      See Also:
    • getCartesianCS

      private org.opengis.referencing.cs.CartesianCS getCartesianCS()
      Used by JAXB only (invoked by reflection). Only one of getCartesianCS() and getAffineCS() can return a non-null value.
      Implementation note: The usual way to handle <xs:choice> with JAXB is to annotate a single method like below: However, our attempts to apply this approach worked for DefaultParameterValue but not for this class: for an unknown reason, the unmarshalled CS object is empty.

    • getAffineCS

      private org.opengis.referencing.cs.AffineCS getAffineCS()
    • setCartesianCS

      private void setCartesianCS(org.opengis.referencing.cs.CartesianCS cs)
      Used by JAXB only (invoked by reflection).
