    Usage

    Basic Usage

    # Use default language (English)
tesseract /path/to/image.png stdout
    Specify language (Chinese + English)
    
tesseract /path/to/image.png stdout -l chi_sim+eng
    Save to file
    
tesseract /path/to/image.png output.txt -l chi_sim+eng
    Multiple languages
    
tesseract /path/to/image.png stdout -l chi_sim+eng+jpn

    Common Language Codes

    | Language | Code | |----------|------| | Simplified Chinese | chi_sim | | Traditional Chinese | chi_tra | | English | eng | | Japanese | jpn | | Korean | kor | | Chinese + English | chi_sim+eng |

    Quick Examples

    # OCR with Chinese support
tesseract image.jpg stdout -l chi_sim
    OCR with mixed Chinese and English
    
tesseract image.png stdout -l chi_sim+eng
    Save to file instead of stdout
    
tesseract document.png result -l chi_sim+eng

    Creates result.txt
