closing_rectangle1 — Close a region with a rectangular structuring element.
closing_rectangle1(Region : RegionClosing : Width, Height : )
closing_rectangle1 performs a
dilation_rectangle1 followed by an
erosion_rectangle1 on the input region
Region. The size of the rectangular structuring element
is determined by the parameters Width and
Height. As is the case for all closing
variants, regions' boundaries are smoothed and holes within a region
which are smaller than the rectangular structuring element are
closed.
closing_rectangle1 is applied to each input region
separately. If gaps between different regions are to be closed,
union1 or union2 has to be called first.
Region (input_object) region(-array) → object
Regions to be closed.
RegionClosing (output_object) region(-array) → object
Closed regions.
Width (input_control) extent.x → (integer)
Width of the structuring rectangle.
Default value: 10
Suggested values: 1, 2, 3, 4, 5, 7, 9, 12, 15, 19, 25, 33, 45, 60, 110, 150, 200

Let F1 be the area of an input region and H be the height of the rectangle. Then the runtime complexity for one region is:
closing_rectangle1 returns 2 (H_MSG_TRUE) if all parameters are
correct. The behavior in case of empty or no input region can be
set via:
no region: set_system('no_object_result',<RegionResult>)
empty region: set_system('empty_region_result',<RegionResult>)
Otherwise, an exception is raised.
