Classes
class	EllipseMatplotlibInterface
class	Axes
	An ellipse core for the semimajor/semiminor axis and position angle parametrization (a,b,theta). More...
class	BaseCore
	A base class for parametrizations of the "core" of an ellipse - the ellipticity and size. More...
class	ConformalShear
	A logarithmic complex ellipticity with magnitude \(|e| = \ln (a/b) \). More...
class	Distortion
	A complex ellipticity with magnitude \(|e| = \frac{a^2 - b^2}{a^2 + b^2}\). More...
class	Ellipse
	An ellipse defined by an arbitrary BaseCore and a center point. More...
class	Parametric
	A functor that returns points on the boundary of the ellipse as a function of a parameter that runs between 0 and 2 pi (but is not angle). More...
class	PixelRegion
class	Quadrupole
	An ellipse core with quadrupole moments as parameters. More...
class	Separable
	An ellipse core with a complex ellipticity and radius parameterization. More...
class	DeterminantRadius
	The radius defined as the 4th root of the determinant of the quadrupole matrix. More...
class	TraceRadius
	The radius defined as \(\sqrt{0.5(I_{xx} + I_{yy})}\). More...
class	LogDeterminantRadius
	The natural logarithm of the DeterminantRadius. More...
class	LogTraceRadius
	The natural logarithm of the TraceRadius. More...
class	ReducedShear
	A complex ellipticity with magnitude \(|e| = \frac{a-b}{a+b} \). More...

def lsst.afw.geom.ellipses.Ellipse_plot	(		self,
			axes = None,
			scale = 1.0,
			show = True,
			rescale = True,
			kwds
	)

Plot the ellipse in matplotlib, adding a MatplotlibInterface
object as the 'matplotlib' attribute of the ellipse.

Aside from those below, keyword arguments for the
matplotlib.patches.Patch constructor are also accepted
('facecolor', 'linestyle', etc.)

Arguments:
axes -------- A matplotlib.axes.Axes object, or None to use
matplotlib.pyplot.gca().
scale ------- Scale the displayed ellipse by this factor.
show -------- If True, update the figure automatically.  Set
to False for batch processing.
rescale ----- If True, rescale the axes.
