iccTiffDump is a command-line tool for extracting ICC profile metadata and technical characteristics from TIFF images. It helps color scientists and developers audit TIFF structure, verify embedded color profiles, and analyze imaging parameters.

🔧 Features

✅ TIFF Metadata Reporting
- Image dimensions, DPI, compression type, photometric model
✅ ICC Profile Analysis
- Extracts embedded ICC profile with PCS, signature, description
✅ Sample Precision Reporting
- Bits per component, sample format, samples per pixel
✅ Tag Visibility
- Shows image layout, color space tags, resolution units
✅ Multilingual Support
