Esta sobrecarga emite a matriz de terminação de linha PDF /LE [/<begin> /<end>] de acordo com a ISO 32000-1 §12.5.6.7 Tabela 175 + Tabela 176. O visualizador representa então as marcas de extremidade fornecidas (setas, traços, formas) sem que o chamador tenha de as desenhar na página. THPDFLineEndingStyle cobre o conjunto completo da Tabela 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

Example

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