Guillem Hermida 872748fb5b Codecs: save DDS textures, uncompressed or BC1–BC3, with optional mipmaps (#1327) (#5993)
DDS textures can now be saved, not just opened: uncompressed (BGRA, BGRX, L8, A8L8; lossless) or BC1/BC2/BC3 (DXT1/3/5) from a clean-room block encoder, with an optional box-filtered mip chain, in the legacy header. Save As and Save a Copy ask with DDS Options; scripts pass `ddsCompression`/`ddsMipmaps` (file commands, control `app.save`, RPC `doc.save`, MCP `doc_save`/`doc_export`), and the CLI takes `--dds-compression`/`--dds-mipmaps`. Targa and DDS answers travel together as `FormatChoices` through the Save As flow.

Review follow-ups:
- File › Save behind DDS or Targa Options records a plain Save with its answer, and replaying `file.save` applies it (#3531).
- The block encoder finds the principal axis from every channel, so a channel that varies on its own can't hide the others' variation.
- DDS joins the shared round-trip suite; the header is built before the output buffer is allocated.
- Enter on a focused Cancel in DDS, Targa or TIFF Options cancels instead of saving.

F4LCON 75978a72f0 Targa: RLE packets end with their scanline (#6382) (#6386)
The image crate's Targa encoder let run-length packets run on from the end of
one row into the next. TGA 2.0 says a packet must not cross a scanline, and
readers that decode a row at a time misread such files: Pillow fails on them
with "buffer overrun", and texture tools and game engines reject them.

Targa is now written by our own encoder (codecs::tga), as Photoshop writes
it: RLE true colour or grayscale, every packet within its row, rows stored
bottom-up (the origin readers that ignore the descriptor assume), the alpha
bits in the descriptor and the TGA 2.0 footer. Reading stays with the image
crate.

Marco Arnulfo b11223b272 Codecs: save Cineon (.cin) film frames
Write Kodak Cineon 4.5: the 1024-byte generic header (V4.5, one or three
channels designated gray or R/G/B, 10 bits, code values 0-1023 over
densities 0-2.048) and a 1024-byte film header left undefined, then the
samples three to a big-endian 32-bit word, left justified (packing 5),
lines on a word boundary. Samples are written as round(v * 1023 / 65535),
so a frame opened from Cineon saves back with its code values; other
images take the encode plan (alpha dropped, CMYK and Lab to RGB) and are
quantized to 10 bits.

Cineon leaves ASYMMETRIC_EXCEPTIONS, Save As offers .cin, and the codecs
README, file-format parity and G10 are updated.

5dafbeeafc Codecs: open Cineon (.cin) film frames read-only (#4691)
* Raw: measure the Nikon D90 image area (4288x2848 at (10, 10))

Aligning the decoded D90 sensor plane with the camera's own JPEG puts the
image at (10, 10) in the 4352x2868 sensor plane, giving the camera's
4288x2848 frame (10-pixel margins; the right border reads the camera's flat
255 from column 4310). Add the measured ImageArea so a D90 NEF opens on the
camera's frame instead of the uncropped plane, and make a measured profile
leave a file that carries its own colour calibration (a DNG) untouched.

* Codecs: open Cineon (.cin) film frames read-only

Cineon is the 10-bit logarithmic film-scan format DPX grew from. Read it from
the same Kodak header family: the generic header (big-endian, orientation at
192, channel count at 193, the channel-1 bits/dimensions), one or three
channels, three 10-bit samples packed into each 32-bit word on a word
boundary. The 10-bit code values open as U16 (round(c x 65535 / 1023)); the
file's log black/white points are a display choice and are not applied. A
depth other than 10 bits or a channel count other than 1/3 is Unsupported;
truncation errors rather than panicking. Read-only (no Cineon writer), so
.cin joins the open filters and Cineon read closes part of #1049's G10 gap.

* cargo fmt the extension lists

Sir Starch 6dffa480ac BMP export: Indexed Color documents save as palette BMPs
Saving an Indexed Color document as BMP went through the ordinary RGB
path and wrote a 24-bit file, so the colour table was lost on reopen
(the PNG exporter already had a palette branch).

export_mode_specific now sends Indexed Color to BMP as well as PNG,
through a new encode_bmp_indexed that writes an 8-bit palette BMP with
the document's table. BMP has no transparency, so a transparent index
is written as its palette colour and the export says so.

bmp_palette returned the decoder's 256-entry padding, so a 3-colour BMP
reopened with 253 extra black entries. It now trims the table to the
colours the header declares.

lloydandClaude Opus 5.5 54e7287ba6 Animated WebP: every frame loads into video layers (#1198)
An animated WebP used to bring only its first frame into a video layer. Now
New Video Layer from File, Replace Footage, Reload Frame and Video Frames to
Layers take every frame, as they do for an animated GIF (#572):

- photocraft-codecs: `decode_webp_frames` returns each frame composited onto
  the canvas by image-webp (offsets, blending, disposal), with its duration in
  milliseconds and the file's ICC profile. A still WebP is one frame, read as
  `decode` reads it. A damaged later frame keeps the frames before it and marks
  the first `Truncated`; the frame count and total bytes are checked against
  `Limits`. `webp_is_animated` tells the two apart. New `decode_webp` fuzz
  target.
- photocraft-io: `import_webp_frames`, sharing `import_gif_frames`' loop.
- photocraft-engine: `load_frames` takes an animated WebP's frames; the
  timeline rate comes from the most common duration. A still WebP keeps the
  existing path and the 30 fps default.

Vikram Bhaskaran ab596db6ae Codecs: open Amiga IFF/ILBM bitmaps read-only
Amiga IFF/ILBM (EA 85) artwork opens read-only: the FORM chunks BMHD,
CMAP and BODY, both the interleaved ILBM and planar PBM variants, 1-8
bitplanes through the palette (a grey ramp when there is none), masking
0/1/2, and both stored (0) and ByteRun1/PackBits (1) compression. Chunk
lengths and Run lengths are checked, so a malformed file errors rather
than panicking; other bit-plane counts return Unsupported. No writer, so
.iff/.lbm/.ilbm join the open filters and the format opens in Photoshop
parity's Amiga IFF row.

Vikram Bhaskaran 7b8e21662e Merge origin/main into the DICOM reader; fix the review findings
Address @echelon's review:
- Interleaved/planar sample indexing no longer double-counts the channel and
  uses checked arithmetic and get(), so RGB/YBR cannot index past the pixel
  data; RGB and YBR_FULL require exactly three samples per pixel.
- The transfer syntax is read from (0002,0010) exactly, and the meta walk
  stops at group 0002 (the previous code matched on a literal element number
  and validated the whole file as explicit VR LE, breaking implicit VR and
  big-endian files).
- Undefined-length sequences outside the pixel data are skipped (nested items
  and sequences tracked); encapsulated pixel data is refused.
- Tests added for RGB interleaved and planar, a multi-element meta group, and
  implicit VR.

10ba166a82 feat(codecs): open DDS textures, uncompressed and BC1-BC3 (#1327) (#4255)
A read-only DirectDraw Surface codec on the model of PCX: the top mip
level of a 2D texture, uncompressed (channel masks, RGB or luminance,
8 to 32 bits) or BC1/BC2/BC3 (DXT1/3/5), with the legacy or the DX10
header. Cubemaps, arrays, volumes and other formats are refused with
an Unsupported error naming what was found; every header field is
treated as hostile (checked sizes, limits before allocating, no
indexing on file offsets).

f48a72cbe3 Codecs: open and save DPX frames (#1049) (#4104)
Read SMPTE 268M DPX in both byte orders (SDPX, XPDS): the first image
element, descriptor 6 (luma), 50 (RGB) or 51 (RGBA), at 8, 10, 12 or 16
bits, with 10-bit packing 0, 1 (method A) or 2 (method B) and 12-bit
packing 0 or 1. 10- and 12-bit code values open as U16
round(c * 65535 / (2^b - 1)) and come back exactly when written at their
depth. No colour transform: the transfer characteristic and colorimetric
specification are reported as import notes; extra image elements are
reported; the orientation is applied on import.

Write big-endian, one unencoded element, at 8, 10, 12 or 16 bits
(EncodeOptions::dpx_bits; `dpxBits` on the save commands, MCP and RPC;
`--dpx-bits` in the CLI), following the document depth by default. Gray
with alpha is written as luma. Creator, project, copyright, creation
time, transfer, colorimetric, frame position, frame rate and time code
travel as DPX:* text metadata and are written back.

Unsupported descriptors, signed or run-length-encoded data and other bit
depths return CodecError::Unsupported; malformed and truncated files
return errors.

BitsStored/HighBit scaling and signed pixel representation. Compressed
syntaxes, sequences, multi-frame data and other photometric interpretations

f14817a5d2 Animated GIF: every frame loads into video layers (#572) (#2999)
* feat(codecs): decode every frame of an animated GIF (#572)

decode_gif_frames returns each frame composited onto the logical screen
(disposal methods applied) with its delay in milliseconds. decode still
keeps the first frame only. A damaged later frame keeps the frames before
it and marks the first with DecodeWarning::Truncated; dimensions, the
total decoded bytes and a frame cap are checked against the limits.

* feat(io): import_gif_frames hands each GIF frame over as a document (#572)

A frame at a time becomes a single-layer document, so a caller can
flatten and drop it instead of holding every frame twice.

* feat(engine): animated GIFs load every frame into video layers (#572)

New Video Layer from File, Replace Footage, Reload Frame and Video Frames
to Layers take all frames of a GIF instead of the first. The timeline rate
comes from the GIF's delays (the most common one, delays under 20 ms shown
at 100 ms as browsers do); an explicit fps still wins.

291f30da55 EXR: Cryptomatte layers list, decode and hash to the specification (#2180)
* EXR: Cryptomatte layers list, decode and hash to the specification

Cryptomatte (specification 1.2) carries per-pixel object and material
IDs with coverage in <layer>NN.red/.green channel pairs, announced by
cryptomatte/<key>/name|hash|conversion|manifest header attributes - the
ID channels Arnold, V-Ray, Redshift, Mantra/Karma and Cycles write next
to the beauty pass.

cryptomatte_layers lists every layer from the headers alone (name, key,
channels, the embedded manifest parsed and capped at 16 MiB, a sidecar
pointer); decode_cryptomatte returns the per-pixel (ID, coverage) pairs
above zero, sorted by descending coverage; cryptomatte_id hashes names
the reference way (MurmurHash3 x86-32, the exponent fixed away from
denormals/inf/NaN, read as f32 bits) - verified against the official
test vectors - and cryptomatte_key/cryptomatte_preview_color expose the
metadata key and preview colour. Files with deep parts are refused, like
the other flat part decoders.

* chore(ui): format prefs_ui (the workspace fmt gate is red on main until #2417 lands)

f9ea13a857 EXR: multi-part files open the colour part; exr_info lists them all (#2116)
* EXR: multi-part files open the colour part; exr_info lists them all

A Maya/Arnold render writes one part per AOV. The decoder took part 0
silently, so a depth-only part failed the whole file with "no R/G/B or
Y channels". Now the part that looks most like a colour image opens
(RGBA > RGB > YA > a single channel, earliest wins), with a
DecodeWarning::MoreParts naming how many parts exist.

exr_info lists every part (name, view, size, channels, deep/tiled) from
the headers alone, and decode_exr_part decodes a chosen part — F16 parts
stay F16. Deep parts stay with the deep decoder: a file that has any is
refused here with a pointer to decode_deep_exr, by design.

* EXR: cap the parts' sizes together, move the chosen part out instead of cloning it

Gert Pellin - GPE 58289b2822 fix(codecs): read the resolution from EXIF, XMP and Photoshop APP13; write it consistently (#1691) (#1744)
A camera JPEG (e.g. Nikon D3200) records its resolution only in EXIF IFD0, so it
opened at 72 ppi instead of 300, and saving wrote JFIF 72 next to the source's
EXIF 300.

Reading: a JPEG takes the first usable of APP13 Photoshop ResolutionInfo
(0x03ED), XMP tiff:X/YResolution, EXIF IFD0 X/YResolution + ResolutionUnit
(2 inch, also when absent; 3 cm), and only then the JFIF density. That is the
order Photoshop resolves them in; JFIF comes last because cameras write EXIF
only while many tools write a default JFIF 72. Other formats (WebP, HEIF, PNG
without pHYs, ...) fall back to XMP then EXIF when they have no resolution of
their own. All parsing is bounds-checked; malformed data reads as no
resolution.

Writing: JPEG, PNG, WebP, TIFF (XMP), PSD and Save for Web JPEG rewrite the
EXIF/XMP resolution to the image's: RATIONAL values in place, ResolutionUnit 2,
and an entry that can't be rewritten safely is removed from IFD0 without moving
any other data.

  its layered-document properties), not an error; supported deep EXR opens flattened with a
  DeepFlattened warning, and only deep ZIP and mip/rip-map tiles are unsupported.

* TIFF: BigTIFF, every IFD and SubIFD, banded parallel decode (FILE-215-8)

Large and multi-page TIFFs now open the way Photoshop opens them, quickly and without a second
full-size buffer, and any directory of the file can be opened on request.

* photocraft-codecs `tiff_ifd`: a bounds-checked directory walker for classic TIFF and BigTIFF
  (LONG8 / IFD8, both byte orders). It follows the whole IFD chain and the SubIFD trees (tag
  330) with a seen-set, a depth limit and a 10 000-directory cap, and checks every value range
  against the file. `tiff_info` lists the pages (size, kind: page / reduced-resolution / mask,
  parent, storage); `default_page` is the first full-resolution page of the main chain, so a
  leading thumbnail is skipped. `decode_tiff_page`, `tiff_orientation`, `tiff_page_orientation`.
* Banded decode: the `tiff` crate reads the chosen directory through a patched byte view (header
  -> that IFD, its next pointer -> 0, WhiteIsZero / palette -> BlackIsZero), so SubIFDs and
  cyclic chains decode. The image is allocated once (fallibly, zeroed in parallel) and each
  strip or row of tiles, across every plane, is decoded straight into it, in parallel on native
  targets, with one capped chunk-sized scratch buffer per worker. New: planar configuration 2
  (was an error), palette images (as RGB), 64-bit integers, associated alpha made straight,
  non-alpha extra samples dropped. Image data cut off by the end of the file decodes with a
  `Truncated` warning. Before the crate sees a file: structural tag values must lie inside it,
  the chunk tables must match the geometry (checked in 64 bits; the crate overflowed and
  panicked on `(h / rows + 1) * planes`), and a decompression-bomb guard refuses files far too
  small for their declared size.
* WhiteIsZero and BigTIFF Orientation keep upstream #746's behaviour (#691, #693) through the
  new decode path; regression tests cover both.
* Encode: `EncodeOptions::tiff_bigtiff` writes BigTIFF; without it, BigTIFF is chosen when the
  file could pass 4 GiB (and a classic write that overflows 32-bit offsets is redone as BigTIFF).
* photocraft-io: `import_tiff_page(name, bytes, page)`; the TIFF branch of import goes through it.
* Tests: codecs `tiff_pages.rs` on hand-built files (`tests/common/tiffgen.rs`): BigTIFF LE/BE at
  8/16/32f, padded tiles and planar strips/tiles, pages and SubIFDs, cycles, the IFD cap,
  truncated and past-EOF strips, huge dimensions / counts / tiles, WhiteIsZero, palette, wide
  formats, BigTIFF write, and a cut / bit-flip / random-mutation zoo (an ignored long run did
  200 000 mutations without a panic); io `tiff_pages.rs`. The `decode_tiff` fuzz target walks
  every page. `tiff_bench.rs` (ignored) times a 30 MP decode against the previous path.
* 30 MP RGB (release, 16 threads, same run): Deflate 344 -> 32 ms, LZW 428 -> 43 ms, 16-bit
  Deflate 497 -> 46 ms, uncompressed 15 -> 10 ms, 256 px tiles 36 -> 10 ms, planar error -> 12 ms.
* Scorecard FILE-215-8 done; README and roadmap updated.

47f9306fd0 Open HEIC/HEIF photos (#355) (#372)
* Open HEIC/HEIF photos (#355)

iPhones save HEIC by default and Photoshop opens it; PhotoCraft had no
HEIF code, so .heic was missing from File > Open and failed to decode.

Add Format::Heif to photocraft-codecs, decoded by heic-rs (pure Rust,
forbid(unsafe), MIT OR Apache-2.0, wasm-ready): single pictures and
grid-tiled photos, 8-bit to U8 and 10/12-bit to U16, auxiliary alpha,
ICC, EXIF and XMP. The container's irot/imir/clap are applied and EXIF
Orientation is rewritten to 1, so photos are never turned twice. Limits
are checked against the declared size before decoding. Read-only (no
pure-Rust HEVC encoder), listed in ASYMMETRIC_EXCEPTIONS.

File > Open (desktop, web) and the batch list accept heic/heif/hif.
Tests compare against Apple's own decode and a 16-bit source, cover
orientation, metadata, limits and every truncation; fixtures from
heic-rs and pillow-heif are attributed in ATTRIBUTION.md.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* HEIF: pin heic-rs exactly and add a decode_heif fuzz target

Review follow-up: heic-rs is young and parses untrusted files, so pin it
(=0.1.1) and fuzz the HEIF path. The target covers both orientation
paths and is meant to run with -timeout so a hang is reported, not
only a panic. It is added to the CI fuzz matrix.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* HEIF: a heic-rs panic is a malformed-file error, not a crash

Fuzzing decode_heif found two out-of-range slices in heic-rs 0.1.1 on
malformed files:
- in its box parser (boxes.rs:130), reachable from a 72-byte file, even
  through the metadata-only probe;
- during HEVC reconstruction (hevc/decode/recon.rs:70).

The background job path catches panics, but the synchronous ones (jobs
off, the CLI) did not. The HEIF codec now runs the decoder under
catch_unwind and reports a panic as CodecError::Malformed, as
gpu/health.rs already does around wgpu.

The fuzz target also calls heic-rs directly, so its panics still reach
the fuzzer. The 72-byte input is a regression test, which fails
without the guard.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* HEIF: move the decoder into an optional photocraft-heif crate

The heic-rs decoding from #372 now lives in `crates/heif` (photocraft-heif, standalone, depends
only on heic-rs =0.1.1): probe, decode with a pixel limit, container transforms, alpha, 8/10-bit,
ICC/EXIF/XMP and the catch_unwind guard, behind a small API of its own (Info, Options, Decoded,
Error). photocraft-codecs uses it behind a new non-default `heif` feature; the apps and
photocraft-io forward it. HEIF detection, extensions and mime stay compiled in, so without the
feature a HEIC file is still recognised and opening it is a clear "HEIC/HEIF support isn't
included in this build of PhotoCraft" error. `cargo xtask layers` allows exactly codecs -> heif
between standalone crates.

The fixtures are no longer committed: `cargo xtask corpus --heif` fetches them from heic-rs
(tests/fixtures, v0.1.1) and pillow-heif (tests/images) at pinned commits, verified against
xtask/heif-corpus.sha256 (same bytes as the PR's copies). The fixture tests run with
`--features corpus,heif` (`cargo xtask test-corpus` enables both).

* Build CI and official binaries with HEIC support (--features heif)

CI test and clippy, the FreeBSD job, and the macOS, Linux (and Flatpak), FreeBSD, Windows and
web packaging all build with the `heif` feature; CI also tests codecs/io without it on Linux so
the "not in this build" path stays covered. `cargo xtask wasm` also checks photocraft-codecs with
`--features heif`.

BFlatandClaude Opus 5.5 8a8371395b Import warns when it keeps only the first frame or page, or a JPEG ends early (#518, #523) (#563)
Decoders now report what the decoded image doesn't show in a new
`Image::warnings` (`photocraft_codecs::DecodeWarning`), and `image_to_document`
turns them into import warnings, so they reach `photocraft-cli info` /
`convert` stderr, `doc.open` over MCP and serve, and the app's open notice
through the existing import-warnings path.

* #523: APNG (acTL frames, plus a default image outside the animation),
  animated GIF (image descriptors counted by walking the blocks), animated
  WebP and multi-page TIFF (IFDs walked without decoding; reduced-resolution
  copies and transparency masks are not pages) say "only the first of N
  frames/pages was imported". Single images stay quiet; the kept frame's
  pixels are unchanged.
* #518: a JPEG whose data runs out before its end-of-image marker (marker
  segments skipped by length, scan data by byte stuffing) still decodes
  leniently but warns "JPEG data ends early (the file is truncated or
  damaged); part of the image is missing". A JPEG that ends before any scan
  data is an error.

Brandon ThomasandClaude Opus 5.5 d3b540234c Large images: adapter texture limits, banded compositing/export, proxy thumbnails, history byte budget (#71)
* Compose: render in place and in bands; area-reduced and proxy thumbnails

render_tiled wrote every tile into a Vec and then copied them into the output:
two full-size float copies (6.3 GB for a 14000² document). Tiles are now
written straight into the output band by band.

New streaming APIs so large documents never need a full-size float
composite: render_bands (sink per band of ~8 MP), render_reduced (banded
area average, bit-identical to the old flatten-then-average thumbnail) and
flatten_to_surface (Flatten Image, Merge Visible, Copy Merged and the other
flattened-surface users).

thumbnail() reduces a downsampled proxy (moved from ui-egui to
compose::proxy, now also scaling spot channels) for documents over 16 MP
when that is faithful (no layer effects or vector masks), so navigator,
channel and histogram thumbnails of a 196 MP document cost milliseconds.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* GPU canvas: request the adapter's real limits; banded CPU fallback; navigator thumbnail

egui-wgpu asks for an 8192 px texture limit, so the wgpu compositor rejected
every document wider or taller than 8192 px and each refresh fell back to a
full CPU flatten. The desktop and web apps now request the adapter's own
max_texture_dimension_2d and max_buffer_size (gpu_canvas::use_adapter_limits);
the benches use the same limits.

The CPU fallback (documents beyond the GPU limit, or features it lacks) is
GpuCanvas::refresh: it renders and uploads the composite band by band
instead of a full float composite plus a full RGBA8 copy. The CPU canvas
texture is reduced in bands too, and the Navigator on the GPU canvas uses a
cached thumbnail instead of a full-resolution CPU composite per revision.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* IO: banded export and import; no full-size copies in encoders; larger decode limits

- Flat export renders the composite in bands and quantises each band; alpha
  is dropped in place when every pixel is opaque. The single-layer native
  path copies surface rows a band at a time (no f32 read_region and no
  per-pixel Vec). Buffers come from try_reserve: Err, not an abort.
- PSD export encodes the merged image band by band into its planes (no
  flatten, no second plane copy); near-opaque documents are re-encoded
  without the white matte so the output is unchanged. Layer interleaved
  bytes are freed before their planes are compressed.
- Flat import converts in ~32 MB bands (and not at all when already RGBA);
  the PSD merged-image un-matte works per tile row.
- Encoders borrow the image when no conversion is needed (Image::converted)
  instead of cloning it; PNG only copies 16-bit data for the byte swap.
- Decode limits: 2^30 pixels and 8 GiB on 64-bit targets (a 20000² JPEG
  was refused at 2^28).

* Filters: write tile results in memory-bounded groups

apply_tiled collected every tile's float result before writing any (3.1 GB
for a 14000² layer). Results are now produced and written in groups of about
256 MB (at least one tile per core).

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* History: bound pixel memory by Preferences > Performance > Memory Usage

History::max_bytes caps the current document's tiles plus the tiles only
history holds (layers, masks, alpha channels); History::trim drops the
oldest states beyond it after every recorded step and when preferences
change, always keeping the last step undoable. The engine sets it from
memory_usage_mb, which was unused.

* Large-image benchmark (14k / 20k): open, refresh, thumbnails, filter, stroke, saves

One operation per run on a cached synthetic photo, with the GPU device created
the way the app creates it, so /usr/bin/time -l reports that operation's peak
memory. Documented in docs/development.md.
