gen_region_polygon_xldgen_region_polygon_xldGenRegionPolygonXldGenRegionPolygonXld (Operator)
Name
gen_region_polygon_xldgen_region_polygon_xldGenRegionPolygonXldGenRegionPolygonXld — Create a region from an XLD polygon.
Signature
Herror gen_region_polygon_xld(const Hobject Polygon, Hobject* Region, const char* Mode)
Herror T_gen_region_polygon_xld(const Hobject Polygon, Hobject* Region, const Htuple Mode)
Description
gen_region_polygon_xldgen_region_polygon_xldGenRegionPolygonXldGenRegionPolygonXldGenRegionPolygonXld creates a region RegionRegionRegionRegionregion from a
subpixel XLD polygon PolygonPolygonPolygonPolygonpolygon. The polygon is sampled
according to the Bresenham algorithm and influenced by the
parameter 'neighborhood'"neighborhood""neighborhood""neighborhood""neighborhood" of the operator set_systemset_systemSetSystemSetSystemSetSystem. Open
polygons are closed before converting them to regions. Finally, the
parameter ModeModeModeModemode defines whether the region is filled up
('filled'"filled""filled""filled""filled") or returned by its contour ('margin'"margin""margin""margin""margin").
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
