About:
Jxrlib is an open-source implementation of the JPEG-XR (ISO/IEC 29199-2) image format standard. It provides the `JxrEncApp` and `JxrDecApp` command-line utilities for encoding images to the highly efficient JPEG-XR format and decoding existing .jxr or .wdp files. This library is essential for developers and users working with Microsoft's HD Photo technology, offering superior compression ratios compared to traditional JPEG.

Key Features:

Command-line tools for encoding (JxrEncApp) and decoding (JxrDecApp)
Supports the ISO/IEC 29199-2 (JPEG-XR) standard
High-compression lossy and lossless image processing
C-based implementation for portability and performance

Use Cases:

Converting standard image formats to JPEG-XR for archival or web delivery
Decoding legacy Windows Media Photo (.wdp) files on Unix-like systems
Integrating JPEG-XR support into custom image processing pipelines

Alternatives:

libjpeg – Standard JPEG library; Jxrlib offers better compression efficiency but is less universally supported.
libwebp – Google's format; both offer modern compression, though WebP is generally more common on the modern web.
