    • Method Detail

      • 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
      • project

        public ProjCoordinate project​(double lplam,
                                      double lpphi,
                                      ProjCoordinate out)
        Description copied from class: Projection
        Computes the projection of a given point (i.e. from geographics to projection space). This should be overridden for all projections.
        Overrides:
        project in class Projection
        Parameters:
        lplam - the geographic x ordinate (in radians)
        lpphi - the geographic y ordinatee (in radians)
        out - the projected coordinate (in coordinate system units)
        Returns:
        the target coordinate
      • project_s

        public void project_s​(double lplam,
                              double lpphi,
                              ProjCoordinate out)
      • project_e

        public void project_e​(double lplam,
                              double lpphi,
                              ProjCoordinate out)
      • projectInverse

        public ProjCoordinate projectInverse​(double xyx,
                                             double xyy,
                                             ProjCoordinate out)
        Description copied from class: Projection
        Computes the inverse projection of a given point (i.e. from projection space to geographics). This should be overridden for all projections.
        Overrides:
        projectInverse in class Projection
        Parameters:
        xyx - the projected x ordinate (in coordinate system units)
        xyy - the projected y ordinate (in coordinate system units)
        out - the inverse-projected geographic coordinate (in radians)
        Returns:
        the target coordinate
      • projectInverse_s

        public void projectInverse_s​(double xyx,
                                     double xyy,
                                     ProjCoordinate out)
      • projectInverse_e

        public void projectInverse_e​(double xyx,
                                     double xyy,
                                     ProjCoordinate out)
      • isEqualArea

        public boolean isEqualArea()
        Returns true if this projection is equal area
        Overrides:
        isEqualArea in class Projection
        Returns:
        true if this projection is equal-area
