PDFium JXL-in-PDF bringup artifacts (tar.gz base64)
This gist contains the PDFs + rendered PNG outputs from ~/pdf-jxl/.
Because GitHub gists (via gh gist) don’t support uploading binary files directly, the artifacts are bundled as a tarball and base64-encoded.
The tarball contains:

Design Doc: JPEG XL (JXL) image support in PDFium (Rust-only)
Add JPEG XL (JXL) image decoding support to PDFium using jxl-rs, a pure Rust decoder. This enables PDFs that embed JXL-compressed image XObjects (per the upcoming PDF Association / ISO standardization work) to render correctly in PDFium.
JXL benefits:
- 30–50% better compression than JPEG (typical for photographic content)
- Lossless JPEG transcoding (recompress JPEG sources without generation loss)
- Progressive decoding
