GraphicsPath::IsOutlineVisible(REAL,REAL,constPen*,constGraphics*) method (gdipluspath.h)

  • Article

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.

Syntax

BOOL IsOutlineVisible(
  [in] REAL           x,
  [in] REAL           y,
  [in] const Pen      *pen,
  [in] const Graphics *g
);

Parameters

[in] x

Type: REAL

Real number that specifies the x-coordinate of the point to be tested.

[in] y

Type: REAL

Real number that specifies the x-coordinate of the point to be tested.

[in] pen

Type: const Pen*

Pointer to a Pen object. This method determines whether the test point touches the path outline that would be drawn by this pen. More points will touch an outline drawn by a wide pen than will touch an outline drawn by a narrow pen.

[in] g

Type: const Graphics*

Optional. Pointer to a Graphics object that specifies a world-to-device transformation. If the value of this parameter is NULL, the test is done in world coordinates; otherwise, the test is done in device coordinates. The default value is NULL.

Return value

Type: BOOL

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