Herror T_gen_region_polygon(Hobject* Region, const Htuple Rows, const Htuple Columns)
def gen_region_polygon(rows: Sequence[int], columns: Sequence[int]) -> HObject
描述
算子 gen_region_polygongen_region_polygonGenRegionPolygonGenRegionPolygonGenRegionPolygongen_region_polygon creates a region from a polygon
row described by
a series of line and column coordinates. The created
region
consists of the pixels of the routes defined thereby, wherein it is linearly
interpolated between the base points.
注意
The region is not automatically closed and not filled.
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）。
- 在内部数据级别上自动并行化。

示例（HDevelop）
* Polygon-approximation
get_region_polygon(Region,7,Row,Column)
* store it as a region
gen_region_polygon(Pol,Row,Column)
* fill up the hole
fill_up(Pol,Filled)
示例（C）
/* Polygon-approximation */
T_get_region_polygon(Region,7,&Row,&Column);
/* store it as a region */
T_gen_region_polygon(&Pol,Row,Column);
destroy_tuple(Row);
destroy_tuple(Column);
/* fill up the hole */
fill_up(Pol,&Filled);

结果
If the base points are correct the operator gen_region_polygongen_region_polygonGenRegionPolygonGenRegionPolygonGenRegionPolygongen_region_polygon 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.
