Member Function Documentation
| ScTrackedObjectType sc_tracked_object_get_type | ( | ScTrackedObject const * | object | ) |
Get type of the tracked object.
- Parameters
-
object Object for which to retrieve the type. Must not be null.
- Returns
- The type of the object.
- Since
- 5.8.0
| uint32_t sc_tracked_object_get_id | ( | ScTrackedObject const * | object | ) |
Retrieve unique id for the tracked object.
The id is unique for each type of object, e.g. for barcodes. The same id may be reused once the object is lost for another object.
- Parameters
-
object The object for which to retrieve the id. Must not be null.
- Returns
- The unique id.
- Since
- 5.8.0
- Examples:
- CommandLineMatrixScanCameraSample.c.
| ScQuadrilateral sc_tracked_object_get_location | ( | ScTrackedObject const * | object | ) |
Get the location quadrilateral of the tracked object.
- Parameters
-
object The tracked object. Must not be null.
- Returns
- the quadrilateral of the object location.
- Since
- 5.8.0
| ScBarcode * sc_tracked_object_get_barcode | ( | ScTrackedObject const * | object | ) |
Get the tracked barcode object.
The returned barcode instance has to be manually released using sc_barcode_release.
- Parameters
-
object The tracked object. Must not be null.
- Returns
- the tracked barcode object or null if the object is not a barcode.
- Since
- 5.16.0
- Examples:
- CommandLineMatrixScanCameraSample.c.
| void sc_tracked_object_release | ( | ScTrackedObject * | object | ) |
Decrease reference count of tracked object by one.
When the reference count drops to zero, the tracked object is deallocated.
- Parameters
-
object The tracked object. May be null.
- Since
- 5.9.0
| void sc_tracked_object_retain | ( | ScTrackedObject * | object | ) |
Increase reference count of the tracked object by one.
- Parameters
-
object The tracked object. Must not be null.
- Since
- 5.9.0
