gen_polygons_xld — Approximate XLD contours by polygons.
gen_polygons_xld approximates XLD contours (Contours) by polygons. The type of the approximation can be set by Type. The threshold for the approximation is set via Alpha. The procedure is able to process open as well as closed contours. The resulting approximating XLD polygons are returned in Polygons.
Contours can be approximated by the algorithm of Ramer, which approximates contours such that the Euclidian distance of the approximating polygon to the contour is at most Alpha pixel units.
