curve as ter

[jsampson45]

I notice in a document exported as a Simple InkScape Scripting File the term "curve" with six arguments e.g. "curve(1.06066, 1.014545, 2.12132, 2.029089, 3.18198, 3.043634)". I assume these describe bspline curves but I have not been able to find this term "curve" in the wiki. What do the six arguments stand for?

I assume you mean in generated code like this, right?

path([Move(96.0, 49.0), Curve(57.0, 17.0, 35.0, 18.0, 35.0, 45.5), Curve(35.0, 73.0, 135.5, 98.0, 97.5, 112.0), Curve(59.5, 126.0, 35.0, 112.0, 28.5, 93.0)], stroke='#008000', stroke_width=2, stroke_linecap='round', stroke_linejoin='round')

Here, Curve is short for inkex.paths.Curve. (The wiki calls out inkex.paths as a preloaded Python package.) Your assumption is almost correct, but the six arguments in fact represent the $(x_2, y_2)$, $(x_3, y_3)$, and $(x_4, y_4)$ coordinates of a cubic Bézier curve—not a B-spline—drawn from a starting position of $(x_1, y_1)$.
