### Events
| name | description |
|:-----|:------------|
| `clear` | This listener is triggered when the user clears the image_annotator using the clear button for the component. |
| `change` | Triggered when the value of the image_annotator changes either because of user input (e.g. a user types in a textbox) OR because of a function update (e.g. an image receives a value from the output of an event trigger). See `.input()` for a listener that is only triggered by user input. |
| `upload` | This listener is triggered when the user uploads a file into the image_annotator. |
### User function
The impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both).
- When used as an Input, the component only impacts the input signature of the user function.
- When used as an output, the component only impacts the return signature of the user function.
The code snippet below is accurate in cases where the component is used as both an input and an output.
- **As output:** Is passed, a dict with the image and boxes or None.
- **As input:** Should return, a dict with an image and an optional list of boxes or None.
```python
def predict(
value: dict | None
) -> dict | None:
return value
```

See `.input()` for a listener that is only triggered by user input. |\n| `upload` | This listener is triggered when the user uploads a file into the image_annotator. |\n\n\n\n### User function\n\nThe impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both).\n\n- When used as an Input, the component only impacts the input signature of the user function.\n- When used as an output, the component only impacts the return signature of the user function.\n\nThe code snippet below is accurate in cases where the component is used as both an input and an output.\n\n- **As output:** Is passed, a dict with the image and boxes or None.\n- **As input:** Should return, a dict with an image and an optional list of boxes or None.\n\n ```python\n def predict(\n value: dict | None\n ) -> dict | None:\n return value\n ```\n \n",
