Execution Information
Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Automatically parallelized on tuple level.

Complexity
Let F1 be the area of the input region, and F2 be the area of
the structuring element. Then the runtime complexity for one region
is:
Result
minkowski_sub2 minkowski_sub2 MinkowskiSub2 MinkowskiSub2 minkowski_sub2 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>) set_system("no_object_result",<RegionResult>) SetSystem("no_object_result",<RegionResult>) SetSystem("no_object_result",<RegionResult>) set_system("no_object_result",<RegionResult>)
empty region:
set_system('empty_region_result',<RegionResult>) set_system("empty_region_result",<RegionResult>) SetSystem("empty_region_result",<RegionResult>) SetSystem("empty_region_result",<RegionResult>) set_system("empty_region_result",<RegionResult>)
Otherwise, an exception is raised.
