Loading plugins from another package
====================================

It possible to load GazeMovementIdentifier, ScanPathAnalyzer or AOIScanPathAnalyzer plugins from another [python package](https://docs.python.org/3/tutorial/modules.html#packages).

To do so, simply prepend the package where to find the plugin into the JSON configuration file:

```
{
		...
		"gaze_movement_identifier": {
			"my_package.MyGazeMovementIdentifierMethod": {
				"specific_plugin_parameter": 0
			}
		},
		...
		"scan_path_analyzers": {
			"my_package.MyScanPathAnalyzerAlgorithm": {
				"specific_plugin_parameter": 0
			}
		}
		...
		"aoi_scan_path_analyzers": {
			"my_package.MyAOIScanPathAnalyzerAlgorithm": {
				"specific_plugin_parameter": 0
			}
		}
}
```

Then, load your package from the python script where the ArFrame is created.

```python
from argaze import ArFeatures

# Import your own package
import my_package

# Load ArFrame
ar_frame = ArFeatures.ArFrame.from_json('./configuration.json')

# Print ArFrame attributes

for name, scan_path_analyzer in ar_frame.scan_path_analyzers.items():
	print('scan path analyzer type:', type(scan_path_analyzer))
```
