gen_region_polygon_filledT_gen_region_polygon_filledGenRegionPolygonFilledgen_region_polygon_filledGenRegionPolygonFilledGenRegionPolygonFilled — Store a polygon as a “filled” region.
Herror T_gen_region_polygon_filled(Hobject* Region, const Htuple Rows, const Htuple Columns)
The operator gen_region_polygon_filledgen_region_polygon_filledGenRegionPolygonFilledgen_region_polygon_filledGenRegionPolygonFilledGenRegionPolygonFilled creates a region from
a polygon containing the corner points of the region (line and
column coordinates) either clockwise or anti-clockwise.
Contrary to gen_region_polygongen_region_polygonGenRegionPolygongen_region_polygonGenRegionPolygonGenRegionPolygon a “filled” region is
returned here.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.

If the base points are correct the operator gen_region_polygon_filledgen_region_polygon_filledGenRegionPolygonFilledgen_region_polygon_filledGenRegionPolygonFilledGenRegionPolygonFilled
returns the value 2 (H_MSG_TRUE).
Otherwise an exception is raised.
The clipping according to the current image format is set via the
operator set_system('clip_region',<'true'/'false'>)set_system("clip_region",<"true"/"false">)SetSystem("clip_region",<"true"/"false">)set_system("clip_region",<"true"/"false">)SetSystem("clip_region",<"true"/"false">)SetSystem("clip_region",<"true"/"false">).
If an empty region is created (by the clipping or by an empty input)
the operator
set_system('store_empty_region',<'true'/'false'>)set_system("store_empty_region",<"true"/"false">)SetSystem("store_empty_region",<"true"/"false">)set_system("store_empty_region",<"true"/"false">)SetSystem("store_empty_region",<"true"/"false">)SetSystem("store_empty_region",<"true"/"false">) determines
whether the region is returned or an empty object tuple.
