Constructor Detail

ObliqueOrthographic

protected ObliqueOrthographic(ParameterValueGroup parameters)
                       throws ParameterNotFoundException
Constructs an oblique orthographic projection.

Parameters:
parameters - The parameter values in standard units.
Throws:
ParameterNotFoundException - if a mandatory parameter is missing.
Method Detail

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 in ptDst (linear distance on a unit sphere).

Specified by:
transformNormalized in class MapProjection
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 transforming ptSrc, or null. 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 in ptDst.
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 and stores the result in ptDst.

Specified by:
inverseTransformNormalized in class MapProjection
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 transforming ptSrc, or null. Ordinates will be in radians.
Returns:
the coordinate point after transforming x, y and storing the result in ptDst.
Throws:
ProjectionException - if the point can't be transformed.
