smooth_contours_xld — Smooth an XLD contour.
smooth_contours_xld smooths the input XLD contours Contours and returns the smoothed contours in SmoothedContours. The smoothing is done by projecting the contours' points onto a local regression line (i.e., a least-squares approximating line), which is computed from NumRegrPoints on each side of the current contour point. This operator should be called, for example, before contours are scaled.
Contour to be smoothed.
Number of points used to calculate the regression line.
