            [GREG2\]RGMAP /BLANKING Bval Eval

        Override the current blanking value as defined by command  SET BLANKING.
        Contours  are  not  drawn in pixels touching pixels with value V so that
        ABS(V-Bval) <= Eval. This is extremely useful  for  regular  grids  only
        partially filled as often occur in astronomy.
