### Optimal Settings
- **Mixed Documents**: `lang='eng+ind'` (English + Indonesian) - RECOMMENDED
- **Fallback**: `lang='eng'` (English only)
### MCP Tools Usage
```python
# Smart PDF processing with Indonesian support
result = await process_pdf_smart(pdf_path, language='eng+ind')
# OCR with Indonesian language
ocr_result = await perform_ocr(file_path, language='eng+ind')
# Batch processing with Indonesian
batch_result = await batch_process_pdfs(directory, language='eng+ind')
```
### Python Direct Usage
```python
import pytesseract
from PIL import Image
# Load image
image = Image.open('indonesian_document.png')
# OCR with Indonesian + English
text = pytesseract.image_to_string(image, lang='eng+ind')
```
### Command Line Usage
```bash
# OCR PDF with Indonesian support
tesseract input.pdf output.txt -l eng+ind
# OCR image with Indonesian
tesseract document.png result.txt -l eng+ind
```
## Language Codes
- `ind`: Indonesian (Bahasa Indonesia)
- `eng`: English
- `msa`: Malay (Bahasa Malaysia)
- `eng+ind`: English + Indonesian (RECOMMENDED)
## Installation Verification
```bash
tesseract --list-langs
# Should show: eng, ind, msa, osd
```
