名称
gen_region_polygonT_gen_region_polygonGenRegionPolygonGenRegionPolygongen_region_polygon
— Store a polygon as a region.
参数签名
Herror T_gen_region_polygon(Hobject* 区域, const Htuple Rows, const Htuple Columns)
def gen_region_polygon(rows: Sequence[int], columns: Sequence[int]) -> HObject
描述
The operator 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.
运行信息
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on internal data level.

结果
If the base points are correct the operator gen_region_polygongen_region_polygonGenRegionPolygonGenRegionPolygonGenRegionPolygongen_region_polygon
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">)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.
