IMX Developer Preview v0.19.0

IMX Release Notes

IMX v0.19.0 Daily-Use Corpus Hardening

• Adds scripts/daily-use-corpus.sh, a no-oracle installed-binary gate over
  the existing BMP/FARBFELD/JPEG/QOI/PBM/PGM/PNG/PPM surface.
• Proves identify --json and report --json for generated fixtures and
  representative intake variants, then runs prefixed transcode smoke across all
  supported format families.
• Hardens stable diagnostic proof for unsupported prefixes, missing prefixed
  paths, missing inputs, prefix mismatches, unsupported formats, malformed QOI,
  malformed PNM max values, unsupported BMP compression, and identify --json
  failure JSON on stderr.
• Wires the gate into CI, fresh install verification, package smoke,
  release-archive smoke, and generated conformance evidence lookup.
• Keeps the slice bounded: no new formats, stdin/stdout, recursive report or
  batch mode, magick alias, full ImageMagick CLI parsing, metadata/profile
  reporting, delegates, MagickCore, MagickWand, Homebrew/core, crates.io,
  Windows, or hosted macOS/iOS Actions.

IMX v0.18.0 JSON Identify and Report Slice

• Adds imx identify --json [FORMAT:]<input>, a deterministic JSON projection
  of the existing identify metadata: schema_version, format, width,
  height, channels, and depth.
• Adds imx report --json [FORMAT:]<input>, a single-input status report that
  returns supported metadata or status="unsupported" with a stable
  diagnostic_code and message for unsupported, missing, mismatched, or
  malformed inputs.
• Keeps text imx identify [FORMAT:]<input> output unchanged. JPEG JSON width
  and height use the same Orientation-normalized dimensions as text identify.
• Extends CLI tests, self-test, install verification, package smoke,
  release-archive smoke, generated conformance wording, and Homebrew formula
  smoke with JSON identify/report evidence.
• Keeps the slice bounded: no new formats, recursive reporting, stdin/stdout,
  ImageMagick JSON schema compatibility, metadata/profile/color-management
  reporting, histograms, hashes, magick alias, full ImageMagick CLI parsing,
  delegates, MagickCore, MagickWand, Homebrew/core, crates.io, Windows, or
  hosted macOS/iOS Actions.

IMX v0.17.0 Self-Test and Diagnostics Slice

• Adds imx self-test, an offline installed-binary confidence check that
  creates temporary fixtures and invokes the installed imx binary for
  identify, prefixed identify, transcode, exact resize, resize-fit, and
  batch-convert across BMP, FARBFELD, JPEG, QOI, PBM, PGM, PNG, and PPM.
• Extends install verification, package smoke, release-archive smoke,
  differential corpus evidence, benchmark smoke, generated conformance reports,
  and Homebrew formula smoke so release and tap artifacts exercise the same
  user-visible self-test path.
• Tightens CLI diagnostics and exit-code tests for unknown prefixes, mismatched
  prefixes, missing inputs, unsupported BMP variants, invalid geometry,
  same-path output, missing batch output directories, and unsupported command
  shapes.
• Keeps the release bounded: no new formats, stdin/stdout, recursive batch
  mode, magick alias, full ImageMagick CLI parsing, delegates, profiles,
  color management, metadata preservation, MagickCore, MagickWand,
  Homebrew/core, crates.io, Windows, or hosted macOS/iOS Actions.

  preservation, color management, magick alias, full ImageMagick CLI parsing,
  Homebrew/core, crates.io, Windows, or hosted macOS/iOS Actions.

• Supports batch conversion for the existing FARBFELD, JPEG, QOI, PBM, PGM,
  PNG, and PPM surface only, using exact uppercase target formats and existing
  exact input prefixes.
• Reuses existing decode/encode, exact resize, resize-fit, prefix validation,
  and per-output atomic write behavior. Batch outputs are deterministic
  <input-stem>.<target-extension> files in an existing output directory.
• Fails before writing on missing inputs, duplicate planned output names,
  existing outputs, same-path outputs, invalid prefixes, invalid dimensions,
  and unsupported formats. It does not add overwrite mode or collision
  suffixing.
• Extends CLI tests, ImageMagick differential proof, differential corpus,
  install verification, package/archive smoke, benchmark smoke, conformance
  wording, and Homebrew formula/archive smoke with batch-convert evidence.

  PPM input/output surface only, including exact uppercase prefixes.
• Computes the largest integer output dimensions that fit within the requested
  box while preserving source aspect ratio, then uses the same center-sampled
  nearest-neighbor scaling and existing destination encoders as imx resize.
• Extends CLI tests, core image tests, ImageMagick differential proof,
  differential corpus, install verification, package/archive smoke, conformance
  wording, and Homebrew formula/archive smoke with resize-fit evidence.
• Keeps the slice bounded: no change to exact imx resize, no crop, rotate,
  fill, percentages, WIDTHx, xHEIGHT, geometry flags, metadata
  preservation, color management, stdin/stdout, magick alias, full
  ImageMagick CLI parsing, new formats, Homebrew/core, crates.io, Windows, or

• Supports resize for the existing FARBFELD, JPEG, QOI, PBM, PGM, PNG, and PPM
  input/output surface only, including exact uppercase prefixes.
• Uses center-sampled nearest-neighbor scaling to exact dimensions and leaves
  channel/depth conversion to the existing destination encoders.
• Extends CLI tests, core image tests, ImageMagick differential proof,
  install verification, package/archive smoke, conformance wording, and
  Homebrew formula smoke generation with resize evidence.
• Keeps resize bounded: no crop, rotate, percentages, aspect-ratio shorthand,

  rewrites with exact uppercase prefixes.
• Adds a curated intake corpus covering representative generated/in-test cases:
  FARBFELD RGBA16, BMP bottom-up/top-down RGB24/RGBA32, progressive grayscale
  JPEG plus camera-style EXIF Orientation, QOI RGB linear, PBM comments, PGM
  scaled/binary-comment/16-bit samples, PNG grayscale/grayscale-alpha/RGB16/RGBA16,
  and PPM high maxval plus binary-comment input. No externally sourced
  real-world file corpus is claimed.
• Tightens malformed diagnostics by adding operation/path context at the CLI,
  clearer PNM over-max and PBM sample errors, uppercase FARBFELD header
  wording, and precise EOF accounting for truncated QOI multi-byte opcodes.
• Adds resource-boundary proof for the 512 MiB decoded-pixel policy and
  hardens oversized CLI input rejection with a metadata size precheck before
  the bounded read fallback.
• Extends generated fixtures, fuzz seeds, CLI tests, malformed tests, curated
  corpus tests, install verification, package/archive smoke, conformance
  output, and Homebrew formula smoke with v0.12 intake evidence.
• Keeps distribution boundaries unchanged: Linux x86_64 and Linux arm64 release
  archives through Ubuntu-only hosted automation, tap-only Homebrew
  distribution, no Homebrew/core, no crates.io, no Windows, and no hosted macOS
  or iOS GitHub Actions.

IMX v0.11.0 Progressive JPEG Input Slice

  streams. Progressive input works with .jpg, .jpeg, and exact uppercase
  JPEG: operands for identify and transcode.
• Carries forward v0.10.0 read-only EXIF Orientation normalization for
  progressive JPEG input; oriented progressive inputs report oriented
  dimensions and transcode normalized pixels.
• Keeps JPEG output bounded and deterministic: IMX still writes fixed quality
  90 baseline JPEG and does not preserve progressive scan layout, metadata,
  profiles, color management, or source bytes.
• Extends generated fixtures, CLI tests, codec tests, malformed/truncation
  coverage, fuzz se...

  PNG, and PPM surface only, using exact uppercase target formats and existing
  exact input prefixes.
• Reuses existing decode/encode, exact resize, resize-fit, prefix validation,
  and per-output atomic write behavior. Batch outputs are deterministic
  <input-stem>.<target-extension> files in an existing output directory.

  existing outputs, same-path outputs, invalid prefixes, invalid dimensions,
  and unsupported formats. It does not add overwrite mode or collision
  suffixing.
• Extends CLI tests, ImageMagick differential proof, differential corpus,
  install verification, package/archive smoke, benchmark smoke, conformance
  wording, and Homebrew formula/archive smoke with batch-convert evidence.
• Keeps the slice bounded: no recursion, no glob parsing beyond shell-expanded
  input arguments, no stdin/stdout, no watch mode, no parallel execution, no
  metadata preservation, no new formats, no magick alias, no full ImageMagick
  CLI parsing, no Homebrew/core, no crates.io, no Windows, and no hosted
  macOS/iOS Actions.

  PPM input/output surface only, including exact uppercase prefixes.
• Computes the largest integer output dimensions that fit within the requested
  box while preserving source aspect ratio, then uses the same center-sampled
  nearest-neighbor scaling and existing destination encoders as imx resize.
• Extends CLI tests, core image tests, ImageMagick differential proof,
  differential corpus, install verification, package/archive smoke, conformance
  wording, and Homebrew formula/archive smoke with resize-fit evidence.
• Keeps the slice bounded: no change to exact imx resize, no crop, rotate,
  fill, percentages, WIDTHx, xHEIGHT, geometry flags, metadata
  preservation, color management, stdin/stdout, magick alias, full
  ImageMagick CLI parsing, new formats, Homebrew/core, crates.io, Windows, or
  hosted macOS/iOS Actions.

  FARBFELD RGBA16, progressive grayscale JPEG, QOI RGB linear, PBM comments,
  PGM scaled and 16-bit samples, PNG grayscale-alpha/RGBA16, and PPM high
  maxval with comments.
• Tightens malformed diagnostics by adding operation/path context at the CLI,
  clearer PNM over-max and PBM sample errors, uppercase FARBFELD header
  wording, and precise EOF accounting for truncated QOI multi-byte opcodes.
• Adds resource-boundary proof for the 512 MiB decoded-pixel policy and
  hardens oversized CLI input rejection with a metadata size precheck before
  the bounded read fallback.
• Extends generated fixtures, fuzz seeds, CLI tests, malformed tests, curated
  corpus tests, install verification, package/archive smoke, conformance
  output, and Homebrew formula smoke with v0.12 intake evidence.

  90 baseline JPEG and does not preserve progressive scan layout, metadata,
  profiles, color management, or source bytes.
• Extends generated fixtures, CLI tests, codec tests, malformed/truncation
  coverage, fuzz seeds, differential corpus, install verification, package
  smoke, release-archive smoke, conformance output, and Homebrew formula smoke

IMX v0.10.0 Real-Photo Reliability Slice

• Adds bounded read-only JPEG EXIF Orientation handling. Orientation values 1
  through 8 normalize decoded pixels, and identify reports the oriented
  dimensions.
• Keeps metadata behavior narrow: EXIF is not preserved, written, or otherwise
  interpreted beyond Orientation; ICC, XMP, density, thumbnails, timestamps,
  GPS, and camera metadata remain unsupported.
• Extends generated fixtures with deterministic JPEG Orientation 1-8 cases and
  extends the differential corpus with ImageMagick -auto-orient oracle
  evidence plus JPEG lossy metric rows.
• Adds focused codec, CLI, malformed, install, package, release-archive, and

  differential-corpus, benchmark, install, package, archive-smoke, conformance,
  and tap evidence to include JPEG.
• Adds JPEG lossy oracle evidence with recorded RGB8 tolerance metrics rather
  than byte-equality claims.
• Applies a conservative 128 MiB JPEG decoded-pixel cap before decode
  allocation to keep fuzz/resource-safety proof inside the existing 512 MiB
  general image-buffer policy.
• Keeps JPEG bounded: no progressive JPEG, CMYK/YCCK JPEG, 12-bit JPEG,
  arithmetic-coded JPEG, lossless JPEG/JPEG-LS, JPEG 2000, JPEG XL, metadata
  preservation, profiles, color management, orientation handling, or full
  ImageMagick JPEG behavior.

  streams. Progressive input works with .jpg, .jpeg, and exact uppercase
  JPEG: operands for identify and transcode.
• Carries forward v0.10.0 read-only EXIF Orientation normalization for
  progressive JPEG input; oriented progressive inputs report oriented
  dimensions and transcode normalized pixels.

  90 baseline JPEG and does not preserve progressive scan layout, metadata,
  profiles, color management, or source bytes.
• Extends generated fixtures, CLI tests, codec tests, malformed/truncation
  coverage, fuzz seeds, differential corpus, install verification, package
  smoke, release-archive smoke, conformance output, and Homebrew formula smoke
  with progressive JPEG RGB/gray/orientation proof.

  interpreted beyond Orientation; ICC, XMP, density, thumbnails, timestamps,
  GPS, and camera metadata remain unsupported.
• Extends generated fixtures with deterministic JPEG Orientation 1-8 cases and
  extends the differential corpus with ImageMagick -auto-orient oracle
  evidence plus JPEG lossy metric rows.

  differential-corpus, benchmark, install, package, archive-smoke, conformance,
  and tap evidence to include JPEG.
• Adds JPEG lossy oracle evidence with recorded RGB8 tolerance metrics rather
  than byte-equality claims.
• Applies a conservative 128 MiB JPEG decoded-pixel cap before decode
  allocation to keep fuzz/resource-safety proof inside the existing 512 MiB
  general image-buffer policy.
• Keeps JPEG bounded: no progressive JPEG, CMYK/YCCK JPEG, 12-bit JPEG,
  arithmetic-coded JPEG, lossless JPEG/JPEG-LS, JPEG 2000, JPEG XL, metadata
  preservation, profiles, color management, orientation handling, or full
  ImageMagick JPEG behavior.

  to distinguish pre-publish package smoke from post-publish archive smoke.
• Documents and enforces the current Linux archive baseline: published Linux
  binary archives require glibc 2.34 or newer.

  non-interlaced grayscale, RGB, RGBA, and grayscale-alpha PNG inputs with 8-bit
  or 16-bit samples.
• Adds .png detection by PNG signature before extension fallback, exact
  uppercase PNG: prefix handling, PNG identify, PNG transcodes to/from the
  existing FARBFELD/QOI/PBM/PGM/PPM formats, and deterministic PNG same-format
  rewrites.

• Adds exact uppercase FARBFELD:, QOI:, PBM:, PGM:, and PPM:
  prefixes for the existing identify and two-path transcode operands.
• Prefixes are stripped before file IO and must match detected input format or
  output path extension. Unknown prefixes, missing prefi...

  allocation to keep fuzz/resource-safety proof inside the existing 512 MiB
  general image-buffer policy.
• Keeps JPEG bounded: no progressive JPEG, CMYK/YCCK JPEG, 12-bit JPEG,
  arithmetic-coded JPEG, lossless JPEG/JPEG-LS, JPEG 2000, JPEG XL, metadata
  preservation, profiles, color management, orientation handling, or full
  ImageMagick JPEG behavior.
• Keeps distribution boundaries unchanged: Linux x86_64 and Linux arm64 release
  archives through Ubuntu-only hosted automation, generated SHA256SUMS,
  imx.rb, and conformance report assets, tap-only Homebrew distribution, no
  crates.io, no Homebrew/core, no Windows, and no hosted macOS or iOS GitHub
  Actions.

IMX v0.8.1 Release Hardening

• Tightens PNG diagnostics so malformed PNG identify paths report identify
  failures and PNG decoder limit failures surface as image-size limit failures.
• Adds regression coverage for grayscale-alpha PNG identify/decode/transcode and
  for rejected PNG non-goals: interlacing, APNG, tRNS, and oversized rasters.
• Updates generated conformance wording to include high-depth PNG evidence and
  to distinguish pre-publish package smoke from post-publish archive smoke.
• Documents and enforces the current Linux archive baseline: published v0.8.x
  binary archives require glibc 2.34 or newer.
• Hardens Ubuntu-only CI and tap proof with broader workflow path coverage,
  explicit timeouts/concurrency, release tag/version validation, checked-out
  tap formula install tests, and no-macOS tap formula guards.

IMX v0.8.0 PNG Raster Slice

• Adds Rust-native PNG support for a bounded raster surface: static
  non-interlaced grayscale, RGB, RGBA, and grayscale-alpha PNG inputs with 8-bit
  or 16-bit samples.
• Adds .png detection by PNG signature before extension fallback, exact
  uppercase PNG: prefix handling, PNG identify, PNG transcodes to/from the
  existing FARBFELD/QOI/PBM/PGM/PPM formats, and deterministic PNG same-format
  rewrites.
• Encodes PNG deterministically from the normalized IMX raster model. Source
  compression/filter choices, ancillary chunks, comments, timestamps, gamma,
  profiles, EXIF, and other metadata are not preserved.
• Extends CLI, codec, golden, malformed, fuzz-smoke, cargo-fuzz, benchmark,
  install, package, archive-smoke, differential-corpus, and conformance evidence
  to include PNG.
• Keeps PNG bounded: no APNG, indexed/palette PNG, low-bit PNG, tRNS
  color-key transparency, PNG color management/profile semantics, or full
  ImageMagick PNG behavior.
• Carries forward the v0.7.0 high-depth PPM behavior and the v0.6.0 exact
  uppercase prefix behavior for FARBFELD, QOI, PBM, PGM, PNG, and PPM.
• Keeps distribution boundaries unchanged: Linux x86_64 and Linux arm64 release
  archives through Ubuntu-only hosted automation, generated SHA256SUMS,
  imx.rb, and conformance report assets, tap-only Homebrew distribution, no
  crates.io, no Homebrew/core, no Windows, and no hosted macOS or iOS GitHub
  Actions.

IMX v0.7.0 High-Depth PPM

• Adds high-depth PPM support for the existing PPM codec only: uppercase P3
  and P6 with maxval 256..65535 identify and decode as RGB16BE.
• Carries forward the v0.6.0 exact uppercase FARBFELD:, QOI:, PBM:,
  PGM:, and PPM: prefix behavior for identify, transcode, and same-format
  rewrite paths.
• Adds a core RGB16BE image representation so PPM16 can preserve precision when
  transcoding to FARBFELD, PGM16, or same-format PPM output.
• Encodes PPM deterministically as binary P6: maxval 255 for 8-bit sources
  and maxval 65535 for 16-bit RGB/RGBA/GRAY sources.
• Extends CLI, codec, golden, malformed, fuzz-smoke, benchmark, install,
  package, archive-smoke, differential-corpus, and conformance evidence to cover
  the PPM16 slice.
• Keeps the boundary unchanged: no PNG/JPEG/TIFF/PAM/PFM/BMP, no stdin/stdout,
  no magick alias, no full ImageMagick CLI, no delegates, no MagickCore, no
  MagickWand, no crates.io, no Homebrew/core, no Windows, and no hosted macOS or
  iOS GitHub Actions.
• Publishes Linux x86_64 and Linux arm64 release archives through Ubuntu-only
  hosted automation, plus generated SHA256SUMS, imx.rb, and conformance
  report assets. The Homebrew tap update is generated from the published v0.7.0
  SHA256SUMS and remains tap-only, not Homebrew/core.

IMX v0.6.0 Prefix Compatibility

• Adds exact uppercase FARBFELD:, QOI:, PBM:, PGM:, and PPM:
  prefixes for the existing identify and two-path transcode operands.
• Prefixes are stripped before file IO and must match detected input format or
  output path extension. Unknown prefixes, missing prefixed paths, mismatched
  prefixes, and prefixed same-path writes fail with error: ....
• Extends the ImageMagick oracle corpus with prefixed identify cases and a
  prefixed transcode ring across the existing FARBFELD/QOI/PBM/PGM/PPM surface.
• Carries forward the v0.5.0 deterministic identify, cross-format transcode,
  and same-format rewrite surface for FARBFELD, QOI, PBM, PGM, and PPM.
• Publishes Linux x86_64 and Linux arm64 release archives through Ubuntu-only
  hosted automation, plus generated SHA256SUMS, imx.rb, and conformance
  report assets.
• The Homebrew tap update is generated from the published v0.6.0 SHA256SUMS
  and remains tap-only, not Homebrew/core.
• Keeps the boundary unchanged: no new image formats, no stdin/stdout
  streaming, no full ImageMagick CLI, no delegates, no MagickCore, and no
  MagickWand.

IMX v0.5.0 Developer Preview

This preview ships a standalone Rust image-tool binary named imx.

Supported Commands

imx --help
imx --version
imx identify <input.ff|input.farbfeld|input.qoi|input.pbm|input.pgm|input.ppm>
imx <input.ff|input.farbfeld|input.qoi|input.pbm|input.pgm|input.ppm> \
  <output.ff|output.farbfeld|output.qoi|output.pbm|output.pgm|output.ppm>

Supported Formats

• FARBFELD RGBA16BE decode/encode.
• QOI RGB8/RGBA8 decode/encode.
• PBM ASCII P1 and binary P4 bilevel decode; deterministic binary P4
  encode.
• PGM ASCII P2 and binary P5 GRAY8/GRAY16BE decode; deterministic binary
  P5 encode.
• PPM ASCII P3 and binary P6 RGB8 decode; deterministic binary P6 encode.

New In v0.5.0

• Added deterministic same-format rewrites for the existing FARBFELD, QOI,
  PBM, PGM, and PPM slice. imx input.ppm output.ppm and the equivalent
  same-format forms now decode and re-encode to deterministic output when the
  input and output paths are different.
• Expanded the ImageMagick oracle corpus from 20 cross-format transcodes to 25
  directed transcodes, including same-format rewrites for all supported
  formats.
• Kept the release boundary unchanged: no new image formats, no format
  prefixes, no stdin/stdout streaming, no full ImageMagick CLI, no delegates,
  no MagickCore, and no MagickWand.

Carried From v0.4.0

• Hardened the one-command installer so it verifies release checksums, asserts
  the installed binary version, and runs a small identify/transcode smoke test.
• Carried forward release-archive smoke verification. For v0.5.0, hosted
  archive smoke is Linux-only: x86_64-unknown-linux-gnu and
  aarch64-unknown-linux-gnu.
• Homebrew remains tap-only, not Homebrew/core. The v0.5.0 tap update is a
  follow-up from the published release SHA256SUMS.
• Added a generated conformance report (CONFORMANCE_REPORT.md) sourced from
  CI evidence.
• Added a corpus differential report that identifies all supported fixture
  formats and checks directed transcodes against ImageMagick decoded pixels.
• Added scheduled cargo-fuzz with retained crash artifacts and stronger fuzz
  summary metadata.
• Added benchmark threshold summaries and a v0.4.0 baseline regression report
  that records throughput ratios and enforces RSS budgets.
• No new image formats are introduced in v0.5.0; this release is a bounded
  compatibility milestone for the existing FARBFELD/QOI/PBM/PGM/PPM slice.

Known Limits

• PBM input source form is not preserved; P1 input re-encodes as binary P4.
• PBM comments, whitespace, and padding-bit value...
