이 오버로드는 ISO 32000-1 §12.5.6.7 Table 175 + Table 176에 따라 PDF /LE [/<begin> /<end>] 선 끝 배열을 기록합니다. 그러면 호출자가 페이지에 직접 그리지 않아도 뷰어가 지정된 끝점 표시(화살표, 눈금, 도형)를 렌더링합니다. THPDFLineEndingStyle은 Table 176의 전체 집합을 다룹니다:

   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);
