  • Method Details

    • 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
    • hasInverse

      public boolean hasInverse()
      Description copied from class: Projection
      Tests whether this projection has an inverse. If this method returns true then the Projection.inverseProject(ProjCoordinate, ProjCoordinate) and Projection.inverseProjectRadians(ProjCoordinate, ProjCoordinate) methods will return meaningful results.
      Overrides:
      hasInverse in class Projection
      Returns:
      true if this projection has an inverse
    • toString

      public String toString()
      Overrides:
      toString in class Projection
