API

Core

path.Knot(path[, base_path, description, ...])	Represents a Knot and some metadata about it
display.generate_stage3(knot[, width, ...])	Draw the "Stage 3" version of the knot ready to be interleaved.

Path Generation

path.Pt(x, y)	namedtuple for (x, y) coordinates.
path.path_from_pts(points[, scale, closed])	Convert a sequence of points and entrance angles to a Path
path.path_data_to_path(path_data[, closed])	Generate a matpotlib.path.Path object from a list of vertices and codes.
path.gen_curve3(p1, p2[, scale])	A helper to generate a sequence of quadratic Bezier segments.
path.gen_curve4(start_point, exit_angle[, scale])	A helper to generate a sequence of quadratic Bezier segments.

Display

display.show_with_guide(knot[, lw])	Show the knot with Bezier control points.
display.make_guide(knot[, lw])	Make artists to show the knot with Bezier control points.
display.make_stage3(knot[, width, center_alpha])	Draw the "Stage 3" version of the knot ready to be interleaved.

Editor

editor.KnotArtistManager(knot, *[, width])
editor.KnotInteractor(fig, points[, scale, ...])	A path editor.

Knot transforms

path.as_mask(knot, width, *[, dpi, fig_width])	Generate a mask of points "in the ribbon".
path.as_outline(knot[, width, thresh])	Generate the (compound) path of the outline of the knot ribbon.

Path manipulation

path.join(*paths[, close])	Join N paths together with LINETO.
path.reverse(path)	Reverse the given Path.
path.four_fold(path)	Generate a 4-fold symmetric pattern from a Path.
