Detailed Description

template<typename NumericType>
class ELLIPSE< NumericType >

Plain ellipse / elliptical-arc data.

Used by SHAPE_ELLIPSE, by EDA_SHAPE's native ellipse storage, and by importers that need to round-trip ellipses.

ELLIPSE() [2/3]

template<typename NumericType>

ELLIPSE< NumericType >::ELLIPSE	(	const VECTOR2< NumericType > &	aCenter,
		NumericType	aMajorRadius,
		NumericType	aMinorRadius,
		EDA_ANGLE	aRotation,
		EDA_ANGLE	aStartAngle = ANGLE_0,
		EDA_ANGLE	aEndAngle = FULL_CIRCLE )

Constructs an ellipse or elliptical arc.

The ellipse sweeps from aStartAngle to aEndAngle in a counter-clockwise direction.

Parameters

aCenter	is the center point of the ellipse.
aMajorRadius	is the radius of the "x-axis" dimension of the ellipse.
aMinorRadius	is the radius of the "y-axis" dimension of the ellipse.
aRotation	is the angle of the ellipse "x-axis" relative to world x-axis.
aStartAngle	is the starting angle of the elliptical arc.
aEndAngle	is the ending angle of the elliptical arc.

ELLIPSE() [3/3]

template<typename NumericType>

ELLIPSE< NumericType >::ELLIPSE	(	const VECTOR2< NumericType > &	aCenter,
		const VECTOR2< NumericType > &	aMajor,
		double	aRatio,
		EDA_ANGLE	aStartAngle = ANGLE_0,
		EDA_ANGLE	aEndAngle = FULL_CIRCLE )

Constructs a DXF-style ellipse or elliptical arc, where the major axis is given by a point rather than a radius, and therefore defines not only the major radius but also the rotation of the ellipse.

Parameters

aCenter	is the center point of the ellipse.
aMajor	is the endpoint of the major axis, relative to the center.
aRatio	is the ratio of the minor axis length to the major axis length.
aStartAngle	is the starting angle of the elliptical arc.
aEndAngle	is the ending angle of the elliptical arc.
