Public Member Functions
	Graphic2d_Circle (const Handle< Graphic2d_GraphicObject > &aGraphicObject, const Quantity_Length X, const Quantity_Length Y, const Quantity_Length Radius)
	Creates a complete circle. The center is <X>, <Y>. The radius is <Radius>. Warning: Raises CircleDefinitionError if the radius is null.
	Graphic2d_Circle (const Handle< Graphic2d_GraphicObject > &aGraphicObject, const Quantity_Length X, const Quantity_Length Y, const Quantity_Length Radius, const Quantity_PlaneAngle Alpha, const Quantity_PlaneAngle Beta)
	Creates an arc. The center is <X>, <Y>. The radius is <Radius>. Angles are measured counterclockwise with 0 radian at 3 o'clock. Warning: Raises CircleDefinitionError if the radius is null.
void	Center (Quantity_Length &X, Quantity_Length &Y) const
	returns the coordinates of center of the circle
Quantity_Length	Radius () const
	returns the radius of this circle
Quantity_PlaneAngle	FirstAngle () const
	returns the first angle of the arc
Quantity_PlaneAngle	SecondAngle () const
	returns the second angle of the arc
void	SetCenter (const Quantity_Length X, const Quantity_Length Y)
	defines the coordinates of center of the circle
void	SetRadius (const Quantity_Length theR)
	defines the radius of this circle
void	SetAngles (const Quantity_PlaneAngle Alpha, const Quantity_PlaneAngle Beta)
	defines the angles of the arc
virtual void	Save (Aspect_FStream &aFStream) const
Static Public Member Functions
static void	Retrieve (Aspect_IFStream &anIFStream, const Handle< Graphic2d_GraphicObject > &aGraphicObject)
Protected Member Functions
void	Draw (const Handle< Graphic2d_Drawer > &aDrawer)
	Draws the circle <me>.
virtual void	DrawElement (const Handle< Graphic2d_Drawer > &aDrawer, const Standard_Integer anIndex)
	Draws element <anIndex> of the circle <me>.
virtual void	DrawVertex (const Handle< Graphic2d_Drawer > &aDrawer, const Standard_Integer anIndex)
	Draws vertex <anIndex> of the circle <me>.
Standard_Boolean	Pick (const Standard_ShortReal X, const Standard_ShortReal Y, const Standard_ShortReal aPrecision, const Handle< Graphic2d_Drawer > &aDrawer)
	Returns Standard_True if the circle <me> is picked, Standard_False if not.
