node {baseDir}/scripts/ocr.js /path/to/image.jpg --lang chi_tra+eng

  • --lang <langs>: Language codes (default: chi_sim+eng)
  • chi_sim - Simplified Chinese
  • chi_tra - Traditional Chinese
  • eng - English
  • Combine with +: chi_sim+eng
  • --json: Output as JSON instead of plain text

Examples

  • Subsequent runs are cached locally
  • Works best with clear, high-contrast images
