Specs
| Spec | What it is | Version | Status | How it does |
|---|---|---|---|---|
| jxl/jxl | Raw JPEG XL codestreams with a real bit-packed header and metadata; the entropy-coded frame body is a structurally-framed stub, so files do not decode | 1.0 | accepts 0%, covers 15.7%, 19/s | |
| jxl/jxl-frames | Spells out frame internals that jxl stubs out (TOC, LFGlobal, VarDCT/Modular groups, entropy streams); uses placeholder ASCII tag bytes instead of real bit-packed encoding, so files do not decode yet | 1.0 | accepts 0%, covers 10.0%, 53/s | |
| jxl/jxl-frames-boundary | Same as jxl-frames, with values taken from the edges of what the format allows (multiple frame types, colour spaces and extension bundles); fields use fixed byte-aligned approximations rather than true bit-level packing, so files do not decode | 1.0 | accepts 0%, covers 7.2%, 66/s |
