Detailed Description

Draws a parametric function as a path.

Curve(f, low, high, loop, attribute=value)

f                      required         a Python callable or string in
                                        the form "f(t), g(t)"
low, high              required         left and right endpoints
loop                   default=False    if True, connect the endpoints
attribute=value pairs  keyword list     SVG attributes

def svgfig.Curve.__repr__

(

self

)

Definition at line 1515 of file svgfig.py.

def svgfig.Curve.Path	(		self,
			trans = None,
			local = False
	)

Apply the transformation "trans" and return a Path object in
global coordinates.  If local=True, return a Path in local coordinates
(which must be transformed again).

def svgfig.Curve.sample	(		self,
			trans = None
	)

end nested class

Adaptive-sampling algorithm that chooses the best sample points
for a parametric curve between two endpoints and detects
discontinuities.  Called by SVG().

def svgfig.Curve.subsample	(		self,
			left,
			right,
			depth,
			trans = None
	)

Part of the adaptive-sampling algorithm that chooses the best
sample points.  Called by sample().

def svgfig.Curve.SVG	(		self,
			trans = None
	)

Apply the transformation "trans" and return an SVG object.
