PDFium JXL-in-PDF bringup artifacts

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.

Contents

The tarball contains:

  • pdf-jxl/zoltan-jxldecode.pdf
  • pdf-jxl/zoltan-jxldecode.pdf.0.png

Design Doc: JPEG XL (JXL) image support in PDFium (Rust-only)

One-page overview: JPEG XL (JXL) image decoding in PDFium (jxl-rs, Rust-only)

Overview

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

Chromium --app Mode Wayland Subsurface Positioning Bug

Summary

When running Chromium with --app flag on Wayland (Hyprland compositor), popup dialogs (like "Save Password" prompts) appear outside the window bounds, positioned to the top-left of the screen instead of inside the application window.

Environment

  • Compositor: Hyprland 0.53.0
  • Chromium Version: 144.0.7559.109 (Arch Linux)
