gen_region_polygon_filledT_gen_region_polygon_filledGenRegionPolygonFilledGenRegionPolygonFilledgen_region_polygon_filled — Store a polygon as a “filled” region.

def gen_region_polygon_filled(rows: Sequence[Union[int, float]], columns: Sequence[Union[int, float]]) -> HObject

Description

The operator gen_region_polygon_filledgen_region_polygon_filledGenRegionPolygonFilledGenRegionPolygonFilledgen_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_polygonGenRegionPolygonGenRegionPolygongen_region_polygon a “filled” region is returned here. Note that for subpixel coordinates RowsRowsRowsrowsrows and ColumnsColumnsColumnscolumnscolumns the coordinates are rounded before the polygon containing the corner points is determined. Therefore there might be pixels in the RegionRegionRegionregionregion 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_polygonGenRegionPolygonGenRegionPolygongen_region_polygon and fill_upfill_upFillUpFillUpfill_up.

Execution Information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).
  • Multithreading scope: global (may be called from any thread).
  • Processed without parallelization.

Example (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);

Result

If the base points are correct the operator gen_region_polygon_filledgen_region_polygon_filledGenRegionPolygonFilledGenRegionPolygonFilledgen_region_polygon_filled 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">)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">)set_system("store_empty_region",<"true"/"false">) determines whether the region is returned or an empty object tuple.
