get_parallels

Herror ::get_parallels_xld ( Hobject Parallels, HTuple *Row1, HTuple *Col1, HTuple *Length1, HTuple *Phi1, HTuple *Row2, HTuple *Col2, HTuple *Length2, HTuple *Phi2 )

Return an XLD parallel's data (as lines).

::get_parallels_xld returns the following values of the XLD parallels Parallels:

  Row1:        Row coordinates of the points on polygon P1
  Col1:        Column coordinates of the points on polygon P1
  Length1:     Lengths of the line segments on polygon P1
  Phi1:        Angles of the line segments on polygon P1
  Row2:        Row coordinates of the points on polygon P2
  Col2:        Column coordinates of the points on polygon P2
  Length2:     Lengths of the line segments on polygon P2
  Phi2:        Angles of the line segments on polygon P2
