def copy_obj(objects: HObject, index: int, num_obj: int) -> HObject

Description

copy_objcopy_objCopyObjCopyObjcopy_obj copies NumObjNumObjNumObjnumObjnum_obj iconic objects beginning with index IndexIndexIndexindexindex (starting with 1) from the iconic input object tuple ObjectsObjectsObjectsobjectsobjects to the output object ObjectsSelectedObjectsSelectedObjectsSelectedobjectsSelectedobjects_selected. If -1 is passed for NumObjNumObjNumObjnumObjnum_obj 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_objCountObjCountObjcount_obj.

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

IndexIndexIndexindexindex (input_control)  integer HTupleintHTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Starting index of the objects to be copied.

Default: 1

Suggested values: 1, 2, 3, 4, 5, 10, 20, 50, 100, 200, 500, 1000, 2000, 5000

Value range: 1 ≤ Index Index Index index index

Restriction: Index <= number(Objects)

NumObjNumObjNumObjnumObjnum_obj (input_control)  integer HTupleintHTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Example (HDevelop)

gen_circle (Circles, [100,200,400], [200,100,400], [100,100,50])
copy_obj (Circles, CircleCopy, 2, 3)
erosion_circle (CircleCopy, CircleErosion, 15.5)
dev_set_color ('red')
dev_set_draw ('fill')
dev_display(Circles)
dev_set_color ('white')
dev_set_draw ('margin')
dev_display (CircleCopy)
dev_set_color ('green')
dev_display (CircleErosion)

Example (C)

/* Access all regions */

count_obj(Regions,&Num);
for (i=1; i<=Num; i++);
{
  copy_obj(Regions,&Single,i,1);
  T_get_region_polygon(Single,5.0,&Row,&Column);
  T_disp_polygon(WindowHandleTuple,Row,Column);
  destroy_tuple(Row);
  destroy_tuple(Column);
}

Complexity

Runtime complexity: O(|ObjectsObjectsObjectsobjectsobjects| + NumObjNumObjNumObjnumObjnum_obj);

Memory complexity of the result object: O(NumObjNumObjNumObjnumObjnum_obj)

Result

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