Description
The operator select_shape select_shape SelectShape SelectShape select_shape
chooses regions according to
shape. For each input region from Regions Regions Regions regions regions
the indicated
features (Features Features Features features features
) are calculated. If each
(Operation Operation Operation operation operation
= 'and' "and" "and" "and" "and" ) or at least one (Operation Operation Operation operation operation
=
'or' "or" "or" "or" "or" ) of the calculated features is within the default limits
(Min Min Min min min
,Max Max Max max max
) the region is adapted into the output
(duplicated).
The parameters Min Min Min min min
and Max Max Max max max
can be set to
'min' "min" "min" "min" "min" or 'max' "max" "max" "max" "max" in order to leave bottom and top limits,
respectively, open.
Condition:
For an illustration of these features, please refer to the
documentation of this chapter (Regions / Features ).

Result
The operator select_shape select_shape SelectShape SelectShape select_shape
returns the value 2 (
H_MSG_TRUE )
if the
input is not empty. The behavior in case of empty input (no input
objects available) is set via the operator
set_system('no_object_result',<Result>) set_system("no_object_result",<Result>) SetSystem("no_object_result",<Result>) SetSystem("no_object_result",<Result>) set_system("no_object_result",<Result>)
. The behavior in
case of empty region (the region is the empty set) is set via
set_system('empty_region_result',<Result>) set_system("empty_region_result",<Result>) SetSystem("empty_region_result",<Result>) SetSystem("empty_region_result",<Result>) set_system("empty_region_result",<Result>)
. If necessary an
exception is raised.
