AbstractDatum
DefaultImageDatum
- All Implemented Interfaces:
- Serializable, Datum, ImageDatum, IdentifiedObject
public class DefaultImageDatum
- extends AbstractDatum
- implements ImageDatum
Defines the origin of an image coordinate reference system. An image datum is used in a local
context only. For an image datum, the anchor point is usually either the centre of the image
or the corner of the image.

DefaultImageDatum
public DefaultImageDatum(ImageDatum datum)
- Constructs a new datum with the same values than the specified one.
This copy constructor provides a way to wrap an arbitrary implementation into a
Geotools 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:
datum
- The datum to copy.- Since:
- 2.2
DefaultImageDatum
public DefaultImageDatum(String name,
PixelInCell pixelInCell)
- Constructs an image datum from a name.
- Parameters:
name
- The datum name.pixelInCell
- the way the image grid is associated with the image data attributes.
DefaultImageDatum
public DefaultImageDatum(Map<String,?> properties,
PixelInCell pixelInCell)
- Constructs an image datum from a set of properties. The properties map is given
unchanged to the super-class constructor.
- Parameters:
properties
- Set of properties. Should contains at least "name"
.pixelInCell
- the way the image grid is associated with the image data attributes.
getPixelInCell
public PixelInCell getPixelInCell()
- Specification of the way the image grid is associated with the image data attributes.
- Specified by:
getPixelInCell
in interface ImageDatum
- Returns:
- The way image grid is associated with image data attributes.
equals
public boolean equals(AbstractIdentifiedObject object,
boolean compareMetadata)
- Compare this datum with the specified object for equality.
- Overrides:
equals
in class AbstractDatum
- Parameters:
object
- The object to compare to this
.compareMetadata
- true
for performing a strict comparaison, or
false
for comparing only properties relevant to transformations.
- Returns:
true
if both objects are equal.
hashCode
public int hashCode()
- Returns a hash value for this image datum. Name,
remarks and the like are not taken in account. In
other words, two image datums will return the same hash value if they
are equal in the sense of
equals
(AbstractIdentifiedObject, false)
.
- Overrides:
hashCode
in class AbstractIdentifiedObject
- Returns:
- The hash code value. This value doesn't need to be the same
in past or future versions of this class.
formatWKT
protected String formatWKT(Formatter formatter)
- Format the inner part of a
Well
Known Text (WKT) element.
Note: WKT of image datum is not yet part of OGC specification.
- Overrides:
formatWKT
in class AbstractDatum
- Parameters:
formatter
- The formatter to use.
- Returns:
- The WKT element name.
