## Description

Test node that publishes synthetic image data for testing cv_bridge functionality. The node generates a black image with an animated bouncing white circle and publishes both regular and compressed image messages at 30 Hz. This is useful for testing OpenCV-ROS2 image conversion and transmission pipelines.

## Publishers

- `/opencv_tests/images` ([sensor_msgs/msg/Image](https://docs.ros2.org/latest/api/sensor_msgs/msg/Image.html))
  - Raw image messages showing a bouncing white circle on a black background (480x640 grayscale)
  
- `/opencv_tests/images/compressed` ([sensor_msgs/msg/CompressedImage](https://docs.ros2.org/latest/api/sensor_msgs/msg/CompressedImage.html))
  - Compressed version of the same image data

## Example Usage

Launch the source node to generate test images:

```bash
ros2 run opencv_tests source
```

To visualize the published images:

```bash
# View raw images
ros2 run rqt_image_view rqt_image_view /opencv_tests/images

# View compressed images
ros2 run rqt_image_view rqt_image_view /opencv_tests/images/compressed
```

The node will continuously publish images with a bouncing ball animation until stopped with Ctrl+C.
