About:
Zimg is a high-performance image processing library that handles scaling, colorspace conversion, and dithering operations. It provides a robust API for precise, high-bit-depth processing while maintaining visual quality and correctness. The library is designed for integration into video processing pipelines and image manipulation applications.
Key Features:
  • High-quality scaling algorithms including bicubic and lanczos
  • Accurate colorspace conversion with full range/limited range support
  • High bit-depth processing (up to 32-bit float)
  • Dithering and quantization utilities
  • Thread-safe and optimized for performance
Use Cases:
  • Video encoding pipelines requiring high-quality scaling and colorspace conversion
  • Image processing applications needing accurate color management
  • Research and development in image processing algorithms
Alternatives:
  • libvips – More comprehensive image processing suite with broader format support
  • ImageMagick – Larger library with more features but heavier dependencies
