Graphic2d_EllipsMarker Class Reference

The primitive EllipsMarker
Every marker takes a reference point as an argument in
its constructor. CircleMarker and EllipsMarker take
another point as the center and PolylineMarker takes the
first point of its list as its origin.
The coordinates of the centre or origin point are offsets
with respect to the reference point.

 Graphic2d_EllipsMarker (const Handle< Graphic2d_GraphicObject > &aGraphicObject, const Quantity_Length aXPosition, const Quantity_Length aYPosition, const Quantity_Length X, const Quantity_Length Y, const Quantity_Length MajorRadius, const Quantity_Length MinorRadius, const Quantity_PlaneAngle anAngle)
 Creates an ellipse marker with a reference point.
The reference point is <aXPosition>, <aYPosition>.
The center is <X>, <Y>.
Angles are measured counterclockwise with 0 radian
at 3 o'clock.
Warning: Raises EllipsDefinitionError if the
major radius or the minor radius is null.

void Center (Quantity_Length &X, Quantity_Length &Y) const
 returns the coordinates of center

Quantity_Length MajorRadius () const
 returns the radius of the ellipse marker

Quantity_Length MinorRadius () const
 returns the radius of the ellipse marker

Quantity_PlaneAngle Angle () const
 returns the angle of the ellipse

Standard_Boolean Pick (const Standard_ShortReal X, const Standard_ShortReal Y, const Standard_ShortReal aPrecision, const Handle< Graphic2d_Drawer > &aDrawer)
