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.

Constructor Details
-
DefaultImageDatum
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
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
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.
-
-
Method Details
-
getPixelInCell
Specification of the way the image grid is associated with the image data attributes.- Specified by:
getPixelInCell
in interfaceImageDatum
- Returns:
- The way image grid is associated with image data attributes.
-
equals
Compare this datum with the specified object for equality.- Overrides:
equals
in classAbstractDatum
- Parameters:
object
- The object to compare tothis
.compareMetadata
-true
for performing a strict comparaison, orfalse
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 ofequals
(AbstractIdentifiedObject, false)- Overrides:
hashCode
in classAbstractIdentifiedObject
- Returns:
- The hash code value. This value doesn't need to be the same in past or future versions of this class.
-
formatWKT
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 classAbstractDatum
- Parameters:
formatter
- The formatter to use.- Returns:
- The WKT element name.
