gen_region_polygon_filled — Store a polygon as a “filled” region.
The operator gen_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_polygon a “filled” region is returned here.
Created region.
Line indices of the base points of the region contour.
Default value: 100
Suggested values: 0, 10, 30, 50, 100, 200, 300, 500
Typical range of values: Rows (lin)
Minimum increment: 1
Recommended increment: 1
Column indices of the base points of the region contour.
Number of elements: Columns == Rows
Default value: 100
Suggested values: 0, 10, 30, 50, 100, 200, 300, 500
Typical range of values: Columns (lin)
Minimum increment: 1
Recommended increment: 1
/* 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);
If the base points are correct the operator gen_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'>). If an empty region is created (by the clipping or by an empty input) the operator set_system('store_empty_region',<'true'/'false'>) determines whether the region is returned or an empty object tuple.
