## Installation
### From Crates.io (Rust users)
```bash
cargo install rustocr
```
### From PyPI (Python library)
```bash
pip install easyocr2
```
### From Source
```bash
git clone https://github.com/cyberiums/RustOCR
cd RustOCR
cargo build --release
```
### Docker
```bash
docker-compose up rustocr-server
```

## Usage Examples
### Basic OCR
```bash
rustocr -i image.jpg -l en
```
### Server Mode (Fastest)
```bash
# Terminal 1: Start server
rustocr --server
# Terminal 2: Use server
rustocr -i image.jpg --use-server
```
### Batch Processing
```bash
rustocr --dir './images/*.jpg' --use-server
```
### With Configuration
```bash
rustocr --init-config
rustocr -i doc.jpg --profile chinese
```
### REST API
```bash
python3 easyocr_server_enhanced.py --port 8000
curl http://localhost:8000/docs
```
