Description
copy_objcopy_objCopyObjCopyObjCopyObj copies NumObjNumObjNumObjNumObjnumObj iconic objects
beginning with index IndexIndexIndexIndexindex (starting with 1) from the
iconic input object tuple ObjectsObjectsObjectsObjectsobjects to the output object
ObjectsSelectedObjectsSelectedObjectsSelectedObjectsSelectedobjectsSelected. If -1 is passed for NumObjNumObjNumObjNumObjnumObj
all objects beginning with IndexIndexIndexIndexindex are copied. No new
storage is allocated for the regions and images. Instead, new
objects containing references to the existing objects are created.
The number of objects in an object tuple can be queried with the
operator count_objcount_objCountObjCountObjCountObj.
For a short description of the iconic objects that are available in HALCON
see the introduction of chapter Object.
Execution Information
- Supports objects on compute devices.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.

Complexity
Runtime complexity: O(|ObjectsObjectsObjectsObjectsobjects| + NumObjNumObjNumObjNumObjnumObj);
Memory complexity of the result object: O(NumObjNumObjNumObjNumObjnumObj)
Result
copy_objcopy_objCopyObjCopyObjCopyObj returns 2 (H_MSG_TRUE) if all objects are contained in
the HALCON database and all parameters are correct. If the input
is empty the behavior can be set via
set_system(::'no_object_result',<Result>:)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>).
If necessary, an exception is raised.
