feat: JPEG XL encoder/decoder - #88
Conversation
📝 WalkthroughWalkthroughThe PR adds ChangesJPEG XL codec and CSP validation
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to This PR adds JPEG XL support and expands CI/release automation, but the release path can promote a manually selected ref to main and npm, while repository-controlled commands can access persisted checkout credentials. Public fixture files also lack confirmed redistribution/privacy clearance, and signed-sample handling plus native output memory limits have concrete correctness and availability gaps. The PR is not merge-ready until the release and credential boundaries are fixed and the fixture and codec issues are resolved or explicitly accepted. Sequence Diagram(s)sequenceDiagram

@daker - do you have a sample DICOM you could attach that we can add to viewer-testdata? It would need a statement that the data is anonymized and we have permission to share it publically. |

@wayfarer3130 I used an anonymized test file that I found online. Since I didn’t produce or own the data, i don’t have any authority over the permissions associated with its use. |

The libjxl submodule was declared in .gitmodules but no gitlink was ever
committed, so `git submodule update --init` cloned nothing: the package
could not be built, and with it neither the dist-size guard nor any test
that needs the dist. Pin it at v0.11.1 (794a5dcf), the same revision the
earlier feat/jpeg-xl-emsdk-3174 work used.
libjxl declares ten submodules and this build links three of them
(brotli, highway, skcms — the rest belong to tools and tests that the
CMake options here turn off, and testdata alone is ~110 MB). build.sh
now initialises those three itself, so a plain non-recursive
`git submodule update --init` is enough.
The rest is catching the package up with the pnpm migration on main,
which landed after this branch was cut:
- build:ci ran `yarn run build`; clean used shx, which is not a
dependency anywhere in the repo
- libjxl was missing from release.yml's build matrix, so a release
would have published dicom-codec against a package whose dist was
never built, and from tools/docker/build.sh's WASM_PACKAGES
- .gitignore un-ignored dist/ and build.sh claimed dist was committed,
unlike every sibling codec — dist is build output that CI hands to
the publish job as an artifact
The dist-size baseline is updated to the artifacts this revision
actually produces, verified against a CI-equivalent emsdk 3.1.74 docker
build: every sibling package's entry matched byte-for-byte, so only the
four libjxl entries move.

Adds lossless JPEG XL fixtures built from the cornerstone viewer-testdata
corpus, and a suite that decodes them:
- 16 consecutive 16-bit signed CT slices (512x512, InstanceNumber
64-79 of a 143-slice stack, real values in [-2048, 1704])
- colour whole-slide microscopy tiles: one from the single-frame
instance, two from the smallest multi-frame instance (the corpus has
no two-frame instance, and JPEG XL carries one frame per bitstream
regardless)
The sources are a separate checkout and cannot be vendored, so the
generator writes a manifest of per-fixture SHA-256 pixel hashes and the
tests assert against that — the suite needs no viewer-testdata. The
generator also refuses to write a fixture whose own decode does not
reproduce the source pixels, so a corrupt encode cannot mint its own
reference. Two decoded frames are committed as .raw so a regression
reads as a byte diff rather than only a changed hash.
Coverage: decode geometry and pixels for all 19 fixtures, the signed
16-bit path through getPixelData (Int16Array, range preserved), the
3-component colour path, and lossless re-encode of every CT slice.
Two lossy-path defects found while writing this are pinned rather than
fixed, following the it.fails idiom already used for the
jpeg-lossless-decoder-js bug:
- jpegxl.js sets isSigned:false without offsetting signed samples into
unsigned range, so a CT slice reaches libjxl as two clusters either
side of a 62000-count cliff. At distance 1.0 that is 2211 HU of max
error against a 3752 range. Lossless is unaffected (modular stores
the integers verbatim), as is colour.
- { lossless: false } with no distance never calls setDistance, so the
C++ default of 0.0f makes libjxl run VarDCT at distance 0 — bigger
than the lossless encode and still not lossless.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
JPEG XL cannot carry Pixel Representation. JxlDataType is UINT8, UINT16,
FLOAT or FLOAT16, and JxlBasicInfo describes integer samples only as
bits_per_sample with exponent_bits_per_sample == 0, i.e. unsigned. PS3.5
8.2.15 allows Pixel Representation to be 1 for monochrome JPEG XL images
and says the bit stream's own characteristics are what a decoder shall
use, but defines no mechanism for the difference — so the mapping is a
convention the encoder and decoder have to agree on out of band.
Passing isSigned through was the preferred fix and is not available: the
format has no signed sample type to pass it to. So this picks a
convention per transfer syntax, chosen so the decoder can invert it
knowing only the transfer syntax and not the options the encode ran with:
.110 Lossless — unchanged. The two's complement bits go to libjxl as
unsigned and come back identical, so the frame round-trips byte for
byte, "preserves the bits of the original image" holds literally,
and any reader that applies Pixel Representation itself agrees. The
committed fixtures re-encode to identical bytes, now pinned by a
test.
.112 — level-shifts signed samples up by half the sample range before
encoding and back after decoding. Without it a CT frame reaches
libjxl as [0, 1704] plus [63488, 65535] and lossy coding smears
across the ~62000-count cliff: measured 2211 HU of maximum error at
distance 1.0, against a total range of 3752. Applied to every signed
.112 frame, lossless option or not, so decode can invert it.
Doing this automatically is now bit-identical to a caller shifting by
hand — same bytes, same error, at every distance — which is what
JpegXLEncoder::validate() has always asked callers to do.
Also: { lossless: false } with no distance left the C++ default of 0.0f
in place, so libjxl ran VarDCT at distance 0 — 245685 bytes against
193274 for the lossless encode, and still not lossless. It now defaults
to 1.0, cjxl's default.
The same gap exists in JPEG-LS, which also has no sign flag; pydicom
documents the identical wraparound, and this repo's jpegls.js pins
setNearLossless(0) rather than face it.
Two caveats are documented in the dicom-codec README: a .112 stream of
signed data read by a decoder assuming two's complement is off by
2^(BitsStored-1), and Butteraugli distance is relative to the full
BitsAllocated range, so CT — which uses about 6% of a 16-bit range —
still sees hundreds of HU of error at distance 1.0.

libjxl had no benches at all, and the PR worked around that by adding a
BENCHABLE list to pr-checks.yml that excluded it from every bench
selection, plus a `bench != '[]'` guard so the CodSpeed job would not run
with an empty scope. So the one new codec in the tree was the one codec
with no performance gate.
Adds benches instead, and deletes the workaround:
packages/libjxl/bench/decode.bench.js — cold vs warm decode and encode,
matching the charls and openjphjs suites, over the CT and colour
fixtures dicom-codec already pins, plus instantiate+destroy and the
lossy encode path, which is a different code path in libjxl from
modular lossless.
dispatch.bench.js — .110 decode for greyscale and colour, .110 and
.112 encode, and a JPEG-LS to JPEG XL transcode.
With those in place BENCHABLE has nothing left to exclude, so
pr-checks.yml goes back to main's simpler form and its diff against main
is now the single line adding libjxl to ALL. bench.yml's ALL gains libjxl
too, so the self-hosted simulation gate sweeps it.
The package also gains a vitest config and a module-level smoke test: the
dist loads under Node (the modules are built -sENVIRONMENT=web,worker, so
that depends on wasmBinary being supplied — an assumption both the
benches and dicom-codec's suite rest on), the embind surface is the one
the wrappers call, the decode module carries no encoder, and the C++
guards on signed frame info and on a non-JPEG-XL bitstream both fire.
Adding benches re-seeds the CodSpeed baseline for libjxl: the new
benchmarks have no history until one main run completes.

jpegxl.js reached fs and require.resolve by evaluating the string
"require". That is CommonJS, so a plain require("fs") would be
statically visible to bundlers, which then try to resolve a node builtin
for a browser target — and require.resolve() gets rewritten to a bundler
module id rather than a path. Evaluating the string dodged both, at the
cost of putting a dynamic-code call into every consumer's bundle:
dicom-codec's main is src/index.js, so consumers bundle the source. The
isNode guard stops it running in a browser, but not from being there,
and a strict CSP forbids the call site regardless.
It was also the only such call left in packages/ — the CSP gate only
scans generated dist/, so nothing caught it giving back the property the
CSP-safe codegen work established.
process.getBuiltinModule("module")/("fs") reaches both without a
specifier any bundler can see, and createRequire(__filename) gives a
resolver that resolves paths rather than module ids. packages/ now has
no eval() or Function constructor in hand-written source at all; the
comment here avoids spelling the token so a source scan cannot trip over
the explanation.
getBuiltinModule needs node >= 22.3, so this raises dicom-codec's engines
floor. Both it and libjxl were still claiming ">=0.14", which has been
untrue since long before this: pin them at >=24, matching the root floor
the CI toolchain move sets. The other codec packages still say ">=0.14";
they have no node-specific runtime code, and a consumer installing
dicom-codec gets the strictest floor anyway.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
check-generated-js.js runs from each wasm package's build.sh against its own dist/, so emscripten's output has been gated since the CSP-safe codegen work. Nothing gated the source we write, and the gap was not theoretical: dicom-codec's JPEG XL wrapper reached fs by evaluating the string "require", and dicom-codec's `main` is src/index.js, so consumers bundle that source straight into a browser build where a strict CSP forbids the call site. Adds check-source-js.js over packages/<pkg>/src — the code that is published or bundled. Tests and benches stay out of scope: they never reach a browser, and tools/csp's own fixtures have to contain the very tokens this forbids. It runs in the `test` job (needs nothing from the build matrix, but a job's worth of runner setup would dwarf a check this cheap) and as `pnpm run csp:source`. The pattern list moves to forbidden-dynamic-code.js so both checkers share one definition of CSP-unsafe and cannot drift apart. Behaviour of the existing checker is unchanged — its tests still pass untouched. Verified the gate actually fires: restoring the old construct in jpegxl.js fails it with the offending file named, and the 11 new tests cover each forbidden form, nested directories, the process.getBuiltinModule replacement, and that test/bench/dist are skipped. Also adds the same dist check to libjxl's build.sh, which shipped without the line every one of its five sibling wasm packages has. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Use the input signed-sample field for the level-shift decision.
The fixture helper supplies signed: true but not isSigned. shiftsSigned() therefore returns false for signed .112 frames. The encoder skips toOffsetBinary(), and the decoder skips the inverse conversion.
Derive one signed flag from imageInfo.isSigned ?? imageInfo.signed, then use that flag for conversion and restored metadata.

Confirm redistribution and privacy approval before committing these fixtures.
The fixture corpus has no specified redistribution license, and its metadata includes patient name and ID fields. The committed .jxl and .raw derivatives therefore require written redistribution permission and privacy clearance before being added publicly. Remove or replace the fixtures, or record the applicable authorization, before merging.

Warm the RGB decoder with the RGB fixture.
warmDec retains its CT-sized buffer, but the 8-bit RGB fixture needs more decoded storage. Its first RGB iteration can therefore allocate and distort the warm benchmark. Create warmDecColor, warm it with colorEncoded, and use it for the RGB warm benchmark.

Vitest 3.2.7 benchmark bench callback repeated iterations setup teardown hooks documentation
💡 Result:
In Vitest, benchmarks are defined using the bench function, which is powered by the Tinybench library [1][2]. Benchmarking Basics and Iterations The bench function registers a benchmark task [1][2]. You can control how many times a benchmark runs using options passed as the third argument to bench() [2]. Key options for iterations and timing include: - iterations: The number of times the task should run (default is 10) [2]. - time: The duration (in milliseconds) allocated for running the benchmark task (default is 500ms) [2]. - warmupIterations: Number of warmup iterations (default is 5) [2]. - warmupTime: Duration for the warmup phase (default is 100ms) [2]. Setup and Teardown Hooks Vitest benchmarks support setup and teardown hooks, which are passed within the options object to the bench function [2]. These hooks are executed by the underlying benchmarking provider: - setup: A function that runs before each benchmark task (cycle) [2]. - teardown: A function that runs after each benchmark task (cycle) [2]. Note that these setup and teardown functions are distinct from standard Vitest test lifecycle hooks (like beforeEach or afterEach) [3]. Because setup and teardown in this context are designed for the benchmarking cycle, they are the appropriate place for preparing data or cleaning up resources specifically for the repeated benchmark iterations [3]. Users should be aware that if benchmarks are defined at the top level of a file, they may appear to output results multiple times; wrapping them in a describe block is the recommended practice to avoid this display issue [4].

Create a fresh codec for each cold benchmark iteration.
Vitest repeats each benchmark callback. The module-level coldDecCT, coldDecColor, and coldEnc instances therefore measure cold initialization only on their first invocation.
Create and delete a codec inside each cold callback, or use setup and teardown hooks. Keep the warm instances shared.

@wayfarer3130 the npm publish failed |
… the release commit cancelling main's bench baseline (#93) * fix(release): preflight the registry before publishing anything A new package cannot be released by CI until a human has published it once: npm's OIDC trusted publishing is configured per package on the registry, so there is nothing to configure until the package exists, and `npm trust` cannot create it (npm/cli#8544). CI holds no other npm credential by design, so its first `npm publish` fails with ENEEDAUTH. codec-libjxl landed in #88 and hit exactly that. Worse, the publish step was a bash loop under `set -e`, so it died where it stood -- and libjxl sits fifth in dependency order, so little-endian, openjpeg, openjph and dicom-codec were never attempted. Four packages that would have published fine sat stranded behind one that could not, for three days, each release leaving main tagged for versions that were not on npm. Resolve every package's registry state before publishing anything, so a release that cannot fully succeed publishes nothing and says what a human has to do. `npm view` reports a missing version and a missing package identically (E404), so the two lookups are separate; a non-zero exit that is NOT a 404 is now an error rather than being read as "brand new", which would turn a network blip into an aborted release. Fail-fast rather than skip-and-continue: publishing dicom-codec while a sibling whose range it carries has just failed is the window publish-order.mjs exists to close. The same check runs on every PR as a warning, which is what was missing when #88 merged -- on the PR that adds a codec, "not on npm yet" is simply true. Also: - Port setup-trusted-publishing.sh to node. It computed the repo root with `cd && pwd` and passed it as argv to node, so under Cygwin a Windows node.exe resolved /cygdrive/z/... against the current drive and the scan died with ENOENT. Nothing crosses a shell boundary now, and npm is spawned by its platform-correct name -- node refuses to spawn a .cmd without a shell since CVE-2024-27980, and passing an args array with shell:true is DEP0190, so npm.mjs handles both in one place. - Drive every release entry point from a root package.json script, so none of them depend on a shell. The publish job still installs no dependencies: `npm run` needs no node_modules, and these scripts import only node builtins. - Give packages/libjxl the repository.directory every sibling carries. - Document the bootstrap procedure in tools/release/README.md. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(ci): stop the release commit cancelling main's bench baseline bench.yml groups by `bench-${{ github.head_ref || github.ref }}`, and on a push head_ref is empty -- so every push to main shared the group `bench-refs/heads/main`. With cancel-in-progress: true, the release workflow's version commit (pushed ~5 minutes after the merge that triggered it, into a bench that takes ~11) entered that group, cancelled the merge commit's bench, and was then skipped itself by the gate: 21:45 16f50e3 Expand `hrtime` utility... (#70) cancelled 21:50 91d91bc chore(release): publish skipped 16:56 21d4749 fix: consolidated codec fixes (#73) cancelled 17:01 7abaaa9 chore(release): publish skipped Those merges produced no baseline at all. The gate's guard exists to stop the version commit seeding a DUPLICATE baseline; paired with unconditional cancellation it destroyed the real one and put nothing in its place, so later PRs compared against whatever CodSpeed still held per benchmark. That is how this very PR -- which changes no runtime code -- drew a two-fold "regression" on two dicom-codec dispatch benches while charls reported a two-fold improvement against a pre-serialisation value. Cancel only for pull_request, which was the actual intent: PR churn should supersede itself, one main push must never cancel another. workflow_dispatch stops cancelling too, which is right -- that event is CodSpeed's backtest trigger. This was masked while releases were broken. A release that dies before the push cancels nothing, which is the only reason bac71dd kept its baseline. Fixing the publish path makes the version commit land reliably, so this would have started firing on most merges. Also document in BENCHMARKING.md the two things that CANNOT be fixed from the repo, since both are dashboard-only: archiving the 66 orphaned benchmark entries (harmless -- a skipped bench reuses its baseline on both sides, so its delta is always zero), and acknowledging a regression. Note that neither blocks a merge, because main's ruleset lists no required status checks at all. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(ci,release): address review findings on bench concurrency and trust setup bench.yml: key non-PR runs by commit, not branch. cancel-in-progress: false stops a new run killing a RUNNING one, but a concurrency group still holds only one PENDING run and queueing a third cancels it. With an eleven minute bench, two merges inside that window put the second in the pending slot where a third could evict it - losing a main baseline exactly as before, by another route. github.sha gives every main commit its own group; the bench box's mutex still serialises them, queueing rather than discarding. PRs keep the branch group, where superseding an in-flight bench is the point. setup-trusted-publishing.mjs: stop claiming trusted publishing neutralises a leaked token. `npm trust github` adds an authorized path and revokes nothing - every token that could publish before still can, until each package's Publishing access is set to "Require two-factor authentication and disallow tokens" by hand. The script prints that as a next step and cannot verify it, so the header now says so rather than implying the opposite. setup-trusted-publishing.mjs: skip packages already trusting REPO/WORKFLOW. npm permits one publisher config per package and `npm trust github` fails rather than updating, including when the existing config is identical, so a fully configured workspace recorded nine failures and exited 1 on every re-run - contradicting the "re-running is safe" note directly above. Configs are now read first; ours is skipped as done, one pointing elsewhere is still a failure. The reader tolerates unknown field shapes and biases to attempting the create, because wrongly skipping leaves a package unconfigured until a live release trips over it. BENCHMARKING.md: subject-verb agreement. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(release): keep the bootstrap annotation to one line GitHub renders only the first line of a ::error:: or ::warning:: message in the Checks tab, so emitting the multi-line bootstrap instructions as the annotation showed them cut off mid-sentence -- "1 package(s) have never been published, and npm's OIDC trusted" and no more. The rest was still in the raw log, so nothing was lost, but the part a maintainer sees without opening the job was a fragment. Split the two: bootstrapSummary() is one self-contained line naming the packages, and the existing instructions follow as ordinary log lines. Each annotation and its instructions go to the same stream so they stay adjacent. Chose this over encoding the newlines as %0A because the annotation box is better as a summary than as a twelve-line block, and because naming the packages is the part worth having in the Checks tab. Both paths exercised locally against a throwaway package name npm has never seen: --preflight emits the one-line ::warning:: followed by the full instructions, and the release path emits the one-line ::error::, the instructions, and exits 1 without reaching the publish loop.
