gen_empty_obj — Create an empty object tuple.
gen_empty_obj( : EmptyObject : : )
The operator gen_empty_obj creates an empty tuple. This means that the output parameter does not contain any objects. Thus, the operator count_obj returns 0. However, clear_obj can be called for the output. It should be noted that no objects must not be confused with an empty region. In case of an empty region, i.e. a region with 0 pixels count_obj returns the value 1.
