签名

copy_obj(Objects : ObjectsSelected : Index, NumObj : )

描述

copy_objcopy_objCopyObjCopyObjCopyObjcopy_obj copies NumObjNumObjNumObjNumObjnumObjnum_obj iconic objects beginning with index IndexIndexIndexIndexindexindex (starting with 1) from the iconic input object tuple ObjectsObjectsObjectsObjectsobjectsobjects to the output object ObjectsSelectedObjectsSelectedObjectsSelectedObjectsSelectedobjectsSelectedobjects_selected. If -1 is passed for NumObjNumObjNumObjNumObjnumObjnum_obj all objects beginning with IndexIndexIndexIndexindexindex 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_objCountObjCountObjCountObjcount_obj.

For a short description of the iconic objects that are available in HALCON see the introduction of chapter 对象.

执行信息

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.

参数

Complexity

Runtime complexity: O(|ObjectsObjectsObjectsObjectsobjectsobjects| + NumObjNumObjNumObjNumObjnumObjnum_obj);

Memory complexity of the result object: O(NumObjNumObjNumObjNumObjnumObjnum_obj)

结果

copy_objcopy_objCopyObjCopyObjCopyObjcopy_obj 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>)set_system("no_object_result",<Result>). If necessary, an exception is raised.
