transformNormalized
protected Point2D transformNormalized(double x, double y, Point2D ptDst) throws ProjectionException
Transforms the specified (λ,φ) coordinates (units in radians) and stores the result inptDst
(linear distance on a unit sphere).- Specified by:
transformNormalized
in classMapProjection
- Parameters:
x
- The longitude of the coordinate, in radians.y
- The latitude of the coordinate, in radians.ptDst
- the specified coordinate point that stores the result of transformingptSrc
, ornull
. Ordinates will be in a dimensionless unit, as a linear distance on a unit sphere or ellipse.- Returns:
- the coordinate point after transforming (
lambda
,phi
) and storing the result inptDst
. - Throws:
ProjectionException
- if the point can't be transformed.
-
inverseTransformNormalized
protected Point2D inverseTransformNormalized(double x, double y, Point2D ptDst) throws ProjectionException
Transforms the specified (x,y) coordinates (units in radians) and stores the result inptDst
(linear distance on a unit sphere).- Specified by:
inverseTransformNormalized
in classMapProjection
- Parameters:
x
- The easting of the coordinate, linear distance on a unit sphere or ellipse.y
- The northing of the coordinate, linear distance on a unit sphere or ellipse.ptDst
- the specified coordinate point that stores the result of transformingptSrc
, ornull
. Ordinates will be in radians.- Returns:
- the coordinate point after transforming
x
,y
and storing the result inptDst
. - Throws:
ProjectionException
- if the point can't be transformed.
-
getParameterValues
public ParameterValueGroup getParameterValues()
Returns the parameter values for this map projection.- Overrides:
getParameterValues
in classMapProjection
- Returns:
- A copy of the parameter values for this map projection.
- See Also:
Operation.getParameterValues()
-
hashCode
public int hashCode()
Returns a hash value for this map projection.- Overrides:
hashCode
in classStereographic
-
equals
public boolean equals(Object object)
Compares the specified object with this map projection for equality.- Overrides:
equals
in classStereographic
- Parameters:
object
- The object to compare with this transform.- Returns:
true
if the given object is a transform of the same class and if, given identical source position, the transformed position would be the equals.
