**An Asynchronous Python API Wrapper for AI Enlarger**

[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT) [![Python Versions](https://img.shields.io/pypi/pyversions/aienlarge-py.svg?logo=python&logoColor=white)](https://pypi.org/project/aienlarge-py/)

`aienlarge-py` is an **unofficial** Python library that provides an asynchronous interface to the AI Enlarger image enhancement service. It allows you to programmatically upload images, enhance or enlarge them using AI-powered processes, monitor processing status, and download enhanced results. It leverages `httpx` for efficient non-blocking I/O via `asyncio`.

---

## 🚀 Features

- **Asynchronous API:** Built with `httpx` and `asyncio` for efficient concurrency.
- **Image Upload:** Send images for processing with specified enhancement types and scaling.
- **Status Monitoring:** Check the status of your image processing tasks.
- **Image Downloading:** Retrieve processed images when ready.
- **Robust Error Handling:** Custom exceptions for granular error management.
- **Automatic Configuration:** Generates and persists a username locally for API usage.
- **Retry Logic:** Auto-retries failed requests with exponential backoff.
- **Integrated Logging:** Uses Python’s `logging` module for traceability.

## 📦 Installation

Install via GitHub:

```bash
pip install git+https://github.com/SSL-ACTX/aienlarger-py.git#egg=aienlarge-py
```

Or install from PyPI:

```bash
pip install aienlarge-py
```

## 🧪 Usage Example

```python
import asyncio
import aienlarge
import os

async def main():
    api = aienlarge.ImgLargerAPI()

    image_path = "path/to/your/image.jpg"
    output_dir = "output_images"

    os.makedirs(output_dir, exist_ok=True)

    try:
        # Upload image for 2x enhancement using Default Image Upscaler
        process_code = await api.upload_image(image_path, process_type=0, scale_radio=2)

        if process_code:
            print(f"Upload successful. Process code: {process_code}")

            while True:
                status, download_urls = await api.check_status(process_code)
                print(f"Status: {status}")

                if status == "done" and download_urls:
                    print("Processing complete. Downloading images...")
                    for i, url in enumerate(download_urls):
                        await api.download_image(url, output_dir)
                        print(f"Downloaded image {i+1}/{len(download_urls)}")
                    break
                elif status == "error":
                    print("An error occurred during processing.")
                    break
                else:
                    await asyncio.sleep(5)  # Retry after 5 seconds

    except aienlarge.ImgLargerError as e:
        print(f"API Error: {e}")
    except FileNotFoundError:
        print(f"File not found: {image_path}")
    except ValueError as e:
        print(f"Validation Error: {e}")

if __name__ == "__main__":
    asyncio.run(main())
```

> ✅ **Note:** Replace `"path/to/your/image.jpg"` with your actual file path.

## 🧰 API Reference

### `ImgLargerAPI` Class

#### `__init__(base_url="https://photoai.imglarger.com/api/PhoAi", username=None)`

- `base_url`: Base URL for the API (default: official endpoint).
- `username`: Optional. Will be loaded from config or generated if not provided.

#### `async upload_image(image_path: str, process_type: int, scale_radio: Optional[int] = None) -> Optional[str]`

Uploads an image to be processed.

- `process_type`:
  - `0`: Default Image Upscaler (supports `scale_radio`)
  - `1`: Sharpen
  - `2`: Enhancer Mode (Photo color and contrast)
  - `3`: Retouch Mode (Deblur)
  - `13`: Anime Images Upscaler (supports `scale_radio`)
- `scale_radio`: Optional scale (only for types `0` and `13`). Valid values: `2`, `4`, `8`.

> ⚠️ **Note:** `scale_radio` with a value of 8 is usually for PRO users only, but using it directly in the API may bypass that.

#### `async check_status(process_code: str) -> Tuple[Optional[str], Optional[List[str]]]`

Returns the current processing status and download URLs (if available).

- `status`: `"pending"`, `"processing"`, `"done"`, `"error"`, or `None`
- `download_urls`: List of URLs when status is `"done"`

#### `async download_image(download_url: str, output_path_dir: str)`

Downloads a processed image to the specified directory.

## ❗ Error Handling

Exception classes include:

- `ImgLargerError` (Base)
- `ImgLargerUploadError`
- `ImgLargerStatusError`
- `ImgLargerDownloadError`
- `ImgLargerInvalidProcessTypeError`
- `ImgLargerInvalidScaleRadioError`
- `ImgLargerAPIResponseError`
- `ImgLargerConfigFileError`

These help you implement granular and predictable error handling.

---

## ⚙️ Configuration

- The library stores a username in `.aienlarge_config.json` (created in your working directory).
- If no username is provided, one is generated and saved automatically.

---

## 📚 Dependencies

- [`httpx`](https://www.python-httpx.org/): For async HTTP operations.
