描述
gen_region_polygon_xldgen_region_polygon_xldGenRegionPolygonXldGenRegionPolygonXldGenRegionPolygonXldgen_region_polygon_xld creates a region RegionRegionRegionRegionregionregion from a
subpixel XLD polygon PolygonPolygonPolygonPolygonpolygonpolygon. The polygon is sampled
according to the Bresenham algorithm and influenced by the
parameter 'neighborhood'"neighborhood""neighborhood""neighborhood""neighborhood""neighborhood" of the operator set_systemset_systemSetSystemSetSystemSetSystemset_system。Open
polygons are closed before converting them to regions. Finally, the
parameter ModeModeModeModemodemode defines whether the region is filled up
('filled'"filled""filled""filled""filled""filled") or returned by its contour ('margin'"margin""margin""margin""margin""margin").
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
