Method Detail

project

public Point2D.Double project(double lplam,
                              double lpphi,
                              Point2D.Double xy)

Description copied from class: Projection

The method which actually does the projection. This should be overridden for all projections.

Overrides:

project in class Projection

Parameters:

lplam - Longitude in radians.

lpphi - Latitude in radians.

xy - The projected point.

Returns:

The projected point, identical to parameter dst.

hasInverse

public boolean hasInverse()

Description copied from class: Projection

Returns true if this projection has an inverse

Overrides:

hasInverse in class Projection

initialize

public void initialize()

Description copied from class: Projection

Initialize the projection. This should be called after setting parameters and before using the projection. This is for performance reasons as initialization may be expensive.

Overrides:

initialize in class Projection

toString

public String toString()

Overrides:

toString in class Projection
