class Ellipse

Ellipse draws ellipses and circles. The shape may be non-elliptical if passed through a non-linear coordinate transformation.

Arguments

• Ellipse(x, y, ax, ay, b, attribute=value)*

	x, y		_*required*_		the center of the ellipse/circle
	ax, ay		_*required*_		a vector indicating the length and direction of the semimajor axis
	b		_*required*_		the length of the semiminor axis. If equal to sqrt(ax^2^ + ay^2^), the ellipse is a circle
	attribute=value pairs		_keyword list_		SVG attributes

(If sqrt(ax^2^ + ay^2^) is less than b, then (ax,ay) is actually the semiminor axis.)

SVG method

Ellipse has an *SVG* method, as described in [GeneralPrimitive General features for all primitives].

Path method

Ellipse has a *Path* method, as described in [GeneralPrimitive General features for all primitives].

Defaults

Ellipse has the same defaults as [ClassCurve Curve]. Defaults are described in [GeneralPrimitive General features for all primitives].

	random_sampling		True		if False, bisect with a point exactly halfway between pairs of points; if True, randomly choose a point between 30% and 70%
	recursion_limit		15		number of subdivisions before giving up; if 15, sampling algorithm can visit _at most_ 2^15^ points
	linearity_limit		0.05		maximum deviation (in SVG units) from a straight line
	discontinuity_limit		5		minimum deviation (in SVG units) between points that is considered continuous
