gen_polygons_xldgen_polygons_xldGenPolygonsXldGenPolygonsXld (Operator)

Name

gen_polygons_xldgen_polygons_xldGenPolygonsXldGenPolygonsXld — Approximate XLD contours by polygons.

Signature

Description

gen_polygons_xldgen_polygons_xldGenPolygonsXldGenPolygonsXldGenPolygonsXld approximates XLD contours (ContoursContoursContoursContourscontours) by polygons. The type of the approximation can be set by TypeTypeTypeTypetype. The threshold for the approximation is set via AlphaAlphaAlphaAlphaalpha. The procedure is able to process open as well as closed contours. The resulting approximating XLD polygons are returned in PolygonsPolygonsPolygonsPolygonspolygons.

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 AlphaAlphaAlphaAlphaalpha pixel units.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.
