### Configure Device Resolution

Source: https://www.theimagingsource.com/en-us/documentation/ic4python/guide-grabbing-an-image.html

Sets the resolution of the video capture device using PropId.WIDTH and PropId.HEIGHT. This ensures the camera is in a defined state before operation.

```python
# Set the resolution to 640x480
grabber.device_property_map.set_value(ic4.PropId.WIDTH, 640)
grabber.device_property_map.set_value(ic4.PropId.HEIGHT, 480)

```

--------------------------------

### Configure Device Resolution and Pixel Format

Source: https://www.theimagingsource.com/en-us/documentation/ic4python/guide-configuring-device.html

Sets the device to output Mono8 data and configures the resolution to 640x480. This snippet assumes a device has already been opened.

```python
# Configure the device to output images in the Mono8 pixel format
grabber.device_property_map.set_value(ic4.PropId.PIXEL_FORMAT, ic4.PixelFormat.Mono8)

# Set the resolution to 640x480
grabber.device_property_map.set_value(ic4.PropId.WIDTH, 640)
grabber.device_property_map.set_value(ic4.PropId.HEIGHT, 480)
```

--------------------------------

### Set Fixed Exposure Time and Enable Auto Gain

Source: https://www.theimagingsource.com/en-us/documentation/ic4python/guide-configuring-device.html

Configures the device to a fixed exposure time of 5ms and enables continuous automatic gain control. This snippet is useful for consistent image capture under varying lighting conditions.

```python
# Configure the exposure time to 5ms (5000µs)
grabber.device_property_map.set_value(ic4.PropId.EXPOSURE_AUTO, "Off")
grabber.device_property_map.set_value(ic4.PropId.EXPOSURE_TIME, 5000.0)

# Enable GainAuto
grabber.device_property_map.set_value(ic4.PropId.GAIN_AUTO, "Continuous")
```

--------------------------------

### QueueSinkListener Abstract Methods

Source: https://www.theimagingsource.com/en-us/documentation/ic4python/api-reference.html

Abstract methods for QueueSink listeners to handle sink connection, disconnection, and frame queuing events.

```APIDOC
## Sinks

### _class _QueueSinkListener

Abstract base class for `QueueSink` listener.

### _abstract _sink_connected

Called when the data stream to the sink is created.

#### Parameters
- **sink** (QueueSink) - The sink that is being connected
- **image_type** (ImageType) - The image type the sink is going to receive
- **min_buffers_required** (int) - Indicates the minimum number of buffers required for the data stream to operate. If the event handler does not allocate any buffers, the sink will automatically allocate the minimum number of buffers required.

#### Returns
True to proceed, False to abort the creation of the data stream.

**Note:** The function is executed on the thread that calls `Grabber.stream_setup()`.

### sink_disconnected

Called when the data stream to the sink is stopped.

#### Parameters
- **sink** (QueueSink) - The sink that is being disconnected

**Note:** The function is executed on the thread that calls `Grabber.stream_stop()`.

### _abstract _frames_queued

Called when new images were added to the sink’s queue of filled buffers.

#### Parameters
- **sink** (QueueSink) - The sink that received a frame

**Note:** The function is executed on dedicated thread managed by the sink. When the data stream to the sink is stopped, the `Grabber.stream_stop()` call will wait until this event handler returns. This can quickly lead to a deadlock, if code in the event handler performs an operation that unconditionally requires activity on the thread that called `Grabber.stream_stop()`.
```
