Constructor Detail

EquatorialStereographic

protected EquatorialStereographic(Projection parameters)
                           throws MissingParameterException

Deprecated.

Construct an oblique stereographic projection.

Parameters:

parameters - The parameter values in standard units.

Throws:

MissingParameterException - if a mandatory parameter is missing.

Method Detail

transformNormalized

protected java.awt.geom.Point2D transformNormalized(double x,
                                                    double y,
                                                    java.awt.geom.Point2D ptDst)
                                             throws ProjectionException

Deprecated.

Transforms the specified (x,y) coordinate (units in radians) and stores the result in ptDst (linear distance on a unit sphere).

Overrides:

transformNormalized in class ObliqueStereographic

Parameters:

x - The longitude in radians.

y - The latitude in radians.

ptDst - The destination point, or null.

Returns:

The projected point as a linear distance on a unit sphere.

Throws:

ProjectionException - if the projection failed.
