The GraphicsPath::IsOutlineVisible method determines whether a specified point touches the outline of this path when the path is drawn by a specified Graphics object and a specified pen.


BOOL IsOutlineVisible(
  [in, ref] const Point &  point,
  [in]      const Pen      *pen,
  [in]      const Graphics *g


[in, ref] point

Type: const Point

Reference to the point to be tested.

[in] pen

If the test point touches the outline of this path, this method returns TRUE; otherwise, it returns FALSE.
