## 📖 Examples

Start with these progressive examples in the `examples/` folder:

| Example | Description |
|---------|-------------|
| `01_basic_usage.py` | Core workflow and main loop pattern |
| `02_window_control.py` | Window management and UI controls |
| `03_trackbar_definitions.py` | Custom trackbars and parameter control |
| `04_app_debug_mode.py` | GUI vs headless operation modes |
| `05_viewer_factory_usage.py` | Pre-built viewers for common CV tasks |

### Quick Integration

```python
from ParamTunerCV import ImageViewer, ViewerConfig
import numpy as np
import cv2

config = ViewerConfig()

trackbar_definitions = [
    {"name": "Show Image", "param_name": "show", "max_value": "num_images-1", "initial_value": 0},
    {"name": "Count", "param_name": "count", "max_value": 50, "initial_value": 10}, 
    {"name": "Gauss Size", "param_name": "GaussianSize", "max_value": 31, "callback": "odd", "initial_value": 5}, 
    {"name": "Thresh Val", "param_name": "thresh_val", "max_value": 255, "initial_value": 128}, 
]

IMG_HEIGHT, IMG_WIDTH = 600, 800
viewer = ImageViewer(config, trackbar_definitions)

while viewer.should_loop_continue():
    params = viewer.trackbar.parameters
    
    current_thresh = params.get("thresh_val") 
    current_gaussian_size = params.get("GaussianSize", 5)
    block_count = params.get("count", 10)

    base_color_image = np.full((IMG_HEIGHT, IMG_WIDTH, 3), (block_count * 5, 0, 0), dtype=np.uint8)
    cv2.rectangle(base_color_image, (50, 50), (IMG_WIDTH - 50, IMG_HEIGHT - 50), (0, 255, 0), 3)

    gray_image = cv2.cvtColor(base_color_image, cv2.COLOR_BGR2GRAY)

    gauss_image = cv2.GaussianBlur(gray_image, (current_gaussian_size, current_gaussian_size), 0)

    _, thresh_image = cv2.threshold(gauss_image, current_thresh, 255, cv2.THRESH_BINARY)
    
    viewer.display_images = [
        (base_color_image, "Color"),
        (gray_image, "Grayscale Image"),
        (gauss_image, "Gaussian Blur)"),
        (thresh_image, "Threshold image")
    ]

viewer.cleanup_viewer()
```
