      • project

        public ProjCoordinate project​(double lplam,
                                      double lpphi,
                                      ProjCoordinate out)
        从类复制的说明: Projection
        Computes the projection of a given point (i.e. from geographics to projection space). This should be overridden for all projections.
        覆盖:
        project 在类中 Projection
        参数:
        lplam - the geographic x ordinate (in radians)
        lpphi - the geographic y ordinatee (in radians)
        out - the projected coordinate (in coordinate system units)
        返回:
        the target coordinate
      • projectInverse

        public ProjCoordinate projectInverse​(double xyx,
                                             double xyy,
                                             ProjCoordinate out)
        从类复制的说明: Projection
        Computes the inverse projection of a given point (i.e. from projection space to geographics). This should be overridden for all projections.
        覆盖:
        projectInverse 在类中 Projection
        参数:
        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)
        返回:
        the target coordinate
      • initialize

        public void initialize()
        从类复制的说明: 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.
        覆盖:
        initialize 在类中 Projection
      • isEqualArea

        public boolean isEqualArea()
        Returns true if this projection is equal area
        覆盖:
        isEqualArea 在类中 Projection
        返回:
        true if this projection is equal-area
      • getEPSGCode

        public int getEPSGCode()
        Returns the ESPG code for this projection, or 0 if unknown.
        覆盖:
        getEPSGCode 在类中 Projection
