Radius of circular arc roundovers.

Distance away from the corner the roundover should start.

Distance in from the corner that should be cut off by the roundover.

Width of the segment replacing chamfered corners.

Roundover specification for a corner of a path.

Full roundover specification for a path, either given as a mixed list of pairs of coordinates and corner specifications that apply to them, or a single spec to be applied to all corners of the included path.

chamf spec

Create a chamfered corner specification.

circ spec

Create a circular corner specification.

bez ?curv spec

Create a continuous curvature corner specification. curv sets the smoothness of bezier curvature (default = 0.5).

mix l

Wrap a list of points paired with (optional) corner specifications as a t. Note that it is the users responsibility to leave the specs for the first and last points as None if they intend to treat the path as open.

flat ?closed ~corner path

Create a roundover specification that will apply corner to each of the points in path (other than the first and last points if closed is false, default = true).

chamfers ~kind spec_pts

Create an all chamfer t specification, with variable amplitude of the given kind paired with each point of the path.

circles ~kind spec_pts

Create an all circular t specification, with variable amplitude of the given kind paired with each point of the path.

bezier ?curv ~kind spec_pts

Create an all continuour curvature t specification, with variable amplitude of the given kind paired with each point of the path. Curvature smoothness of all roundovers is set by curv (default = 0.5). If variable smoothness is desired, bez and mix may be used in conjunction to achieve it.
