# Web View

AugeLab Web View is a lightweight monitoring dashboard intended for **headless** runs.

Headless Web View

It shows:

* A live image preview (from your scenario output)
* A rolling log panel (from block/scenario logs)

***

## Start the Web View

All you need to do when you are using web-view, is to use a `Subsystem Out` block to connect to your final image:

Web View Scenario

Then, write a small python script:

{% code title="headless\_webview\.py" %}

```python
from studio import StudioScenario

scenario = StudioScenario()
scenario.load_scenario(r"PATH_TO_SCENARIO.pmod")
scenario.run_server(
    host="127.0.0.1",
    port=8080,
    header="Scenario Server",
)
```

{% endcode %}

Then open:

* `http://127.0.0.1:8080`

Web View Running

## What the dashboard expects from your scenario

### Output image selection

The Web View displays the **first image-like output** produced by the scenario. If your scenario doesn’t output an image, the preview will stay blank.

### Image format

* The preview expects an image output.
* If the array looks like a BGR image (`H x W x 3`), it is channel-swapped to RGB before display.

{% hint style="info" %}
If your scenario’s “first output” is not an image, the dashboard will likely stay blank. In that case, adjust the scenario so the first output group emits an image.
{% endhint %}

***

## Logs

The dashboard shows recent runtime logs.

***

## Operational notes / limitations

* The scenario is executed in an infinite loop in a background thread.
* Stop the server with Ctrl+C.
