);

Arguments:

Name Type Description
hElement HIG_PDE_ELEMENT

The element to test.

  • 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.
