描述
算子 gen_region_polygon_filledgen_region_polygon_filledGenRegionPolygonFilledGenRegionPolygonFilledGenRegionPolygonFilledgen_region_polygon_filled 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_polygonGenRegionPolygonGenRegionPolygonGenRegionPolygongen_region_polygon a “filled” region is
returned here.
Note that for subpixel coordinates RowsRowsRowsRowsrowsrows and ColumnsColumnsColumnsColumnscolumnscolumns the
coordinates are rounded before the polygon containing the corner points is
determined. Therefore there might be pixels in the RegionRegionRegionRegionregionregion which
do not lie on the orignial (subpixel) polygon. An simple alternative in
the case of polygons without holes would be to use the operators
gen_region_polygongen_region_polygonGenRegionPolygonGenRegionPolygonGenRegionPolygongen_region_polygon and fill_upfill_upFillUpFillUpFillUpfill_up。

示例（C）
/* Polygon approximation */
T_get_region_polygon(Region,7,&Row,&Column);
T_gen_region_polygon_filled(&Pol,Row,Column);
/* fill up with original gray value */
reduce_domain(Image,Pol,&New);
结果
If the base points are correct the operator gen_region_polygon_filledgen_region_polygon_filledGenRegionPolygonFilledGenRegionPolygonFilledGenRegionPolygonFilledgen_region_polygon_filled 返回值 2 ( H_MSG_TRUE )。否则将抛出异常。
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">)SetSystem("clip_region",<"true"/"false">)SetSystem("clip_region",<"true"/"false">)set_system("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">)SetSystem("store_empty_region",<"true"/"false">)SetSystem("store_empty_region",<"true"/"false">)set_system("store_empty_region",<"true"/"false">) determines
whether the region is returned or an empty object tuple.
