Calculates a shape from Bezier coefficients
bezier_i(B, nb.pts = 120)
B |
a matrix of Bezier vertices, such as those produced by bezier |
nb.pts |
the number of points to sample along the curve. |
a matrix of (x; y) coordinates
Directly borrowed for Claude (2008), and called beziercurve
there.
Not implemented for open outlines but may be useful for other purposes.
