      • project

        public ProjCoordinate project​(double lam,
                                      double phi,
                                      ProjCoordinate xy)
        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:
        lam - the geographic x ordinate (in radians)
        phi - the geographic y ordinatee (in radians)
        xy - the projected coordinate (in coordinate system units)
        返回:
        the target coordinate
      • projectInverse

        public ProjCoordinate projectInverse​(double x,
                                             double y,
                                             ProjCoordinate lp)
        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:
        x - the projected x ordinate (in coordinate system units)
        y - the projected y ordinate (in coordinate system units)
        lp - the inverse-projected geographic coordinate (in radians)
        返回:
        the target coordinate
      • isEqualArea

        public boolean isEqualArea()
        从类复制的说明: Projection
        Tests whether this projection is equal-area An equal-area projection preserves relative sizes of projected areas.
        覆盖:
        isEqualArea 在类中 Projection
        返回:
        true if this projection is equal-area
