Name Type Description

The element to test.

  • If hElement is Text or an Image, it uses the bounding box of the element to make the check.
  • If the hElement is a Path and it is stroked, it checks if the point is on the path.
  • If the hElement is a Path and it is filled, it checks if the point is in the fill area, taking into consideration whether it is filled using the non-zero winding number rule or the even-odd rule.
lpPoint LPAT_PDF_FIXEDPOINT The point, specified in user space coordinates.
lpbResult LPAT_BOOL TRUE if the point is on the element; FALSE otherwise.
