Defines an ellipse which is strictly smaller than π.

Instance Methods [hide private]
 
__init__(self, center, point_on_main_axis, start, end)
Creates an ellipse defined by the start point, end point, the center and a point on the main axis.
 
__neg__(self)
Returns a view onto the curve with reversed ordering.
 
getCenterPoint(self)
Returns the center.
 
getEndPoint(self)
Returns the end point.
 
getPointOnMainAxis(self)
Returns a point on the main axis.
 
getStartPoint(self)
Returns the start point.
 
isColocated(self, primitive)
Returns True if curves are at the same position.
 
substitute(self, sub_dict)
Returns a copy of self with substitutes for the primitives used to construct it given by the dictionary sub_dict.

Method Details [hide private]

__init__(self, center, point_on_main_axis, start, end)
(Constructor)

 

Creates an ellipse defined by the start point, end point, the center and a point on the main axis.

Overrides: object.__init__

__neg__(self)

 

Returns a view onto the curve with reversed ordering.

Overrides: Primitive.__neg__

getEndPoint(self)

 

Returns the end point.

Overrides: Manifold1D.getEndPoint

getStartPoint(self)

 

Returns the start point.

Overrides: Manifold1D.getStartPoint

isColocated(self, primitive)

 

Returns True if curves are at the same position.

Overrides: Primitive.isColocated

substitute(self, sub_dict)

 

Returns a copy of self with substitutes for the primitives used to construct it given by the dictionary sub_dict. If a substitute for the object is given by sub_dict the value is returned, otherwise a new instance with substituted arguments is returned.

Overrides: Primitive.substitute
