Cette surcharge émet le tableau de terminaisons de ligne PDF /LE [/<begin> /<end>] conformément à ISO 32000-1 §12.5.6.7, tableaux 175 + 176. Le viewer affiche alors les marques d’extrémité fournies (flèches, graduations, formes) sans que l’appelant ait à les dessiner sur la page. THPDFLineEndingStyle couvre l’ensemble du tableau 176 :

   lesNone — no endpoint marker (PDF spec default)
   lesSquare — filled square
   lesCircle — filled circle
   lesDiamond — filled diamond
   lesOpenArrow — open arrowhead
   lesClosedArrow — triangular closed arrowhead
   lesButt — short perpendicular tick
   lesROpenArrow — reverse-direction open arrow
   lesRClosedArrow — reverse-direction closed arrow
   lesSlash — ~30° clockwise short tick

Exemple

PDF.CurrentPage.AddLineAnnotation('Width = 120mm',
  Point1, Point2, lesClosedArrow, lesClosedArrow, clBlue);
