append_arc_to_path(x_start, y_start, x_corner, y_corner, x_end, y_end, dx, dy) click to toggle source

Like adding lines from start to corner to end, but with the corner rounded with a radius equal to the minimum of the actual output distances for dx and dy.

The illustration shows in dark blue the arc that is added for the control points given in red.
