plcurve: Piecewise-Linear Curves (a.k.a. Polygons)¶
The PlCurve class¶
-
class
libpl.plcurve.
PlCurve
¶ It’s a PlCurve.
Create a new PlCurve, optionally with empty components described by
component_spec
.If it is not
None
,component_spec
is a sequence of the form (int num_vertices, bool open, int num_colors).-
add_component
(component)¶ Add a component to this PlCurve.
-
center_of_mass
