crates/engine/src/file_cmds.rs: batch keeps the save-point closure (takes the output path) and also copies the session's authorize hook into each scratch session, as main now does.
crates/raw/src/sensor.rs: both sides cap the memory of retained tiles; kept the existing retained_segment_bytes check (checked multiplication, same limit) and dropped main's duplicate inline loop.
xmp_values advanced its cursor only past the matched key, so the
value-closing search (find(close)) rescanned the remaining packet for
every property-like substring. Repeating text such as
' tiff:ResolutionUnit>' inside the packet produced quadratic CPU work
even when no real resolution property existed.
Advance the cursor past each located value; a missing close delimiter
means the value is unterminated, so no later value can parse and the
scan stops. Valid multi-value extraction is unchanged.

Main added DDS saving (#5993): DDS Options, and FormatChoices carrying the
Targa and DDS answers through every save path (this branch's SaveChoices
carried Targa and JPEG). Resolved by keeping main's name and making it
the one struct for all three answers.
- lib.rs: FormatChoices { tga_bits, dds, jpeg } with from_params (strict),
from_step (lenient JPEG read of a recorded step), apply and record;
main's separate block is folded in. Both prompts (dds_options and
jpeg_options) are kept everywhere: save_to asks Targa, then DDS, then
JPEG Options; save_options_open covers all four. save_in_place takes
main's (path, choices) signature and records the plain-Save step with
plain_save_step for JPEG plus the Targa/DDS answers (save_in_place_with
folded into it). journal_as_plain_save relabels a parked Targa, DDS or
JPEG prompt and keeps tgaBits/dds*/quality/jpegFormat when dropping the
path. replay_save reads choices with from_step.
- SAVE_OPTIONS_OPEN names all four prompts; DDS Options uses it too.
- targa_options_ui: main's plain-Save step (no path) through this
branch's write_answered_save. JPEG Options gets main's Enter-on-a-
focused-Cancel fix.
- view_cmds Save a Copy asks Targa, DDS, then JPEG Options; write_copy
takes FormatChoices.
- control.rs: both app.save tests (JPEG and DDS) kept.
- engine file_cmds: SaveOpts keeps jpeg_format and dds; param docs list
both jpegFormat and ddsCompression/ddsMipmaps. CLI: both --jpeg-format
and --dds-compression/--dds-mipmaps. codecs re-exports JpegFormat and
DdsCompression/DdsOptions.
- docs/book: both entries kept (control-protocol app.save lists both).

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.
Save As and Save a Copy to a JPEG now ask for JPEG Options before writing,
as Photoshop does. Re-creates #4330 on current main and folds in the
unique parts of #5580 (#5563).
- codecs: `JpegFormat` (Baseline, Optimized, Progressive) on
`EncodeOptions`. Progressive writes SOF2. Baseline Optimized fits the
Huffman tables only at 4:4:4 (Gray, CMYK) or with Progressive: fitted
tables make the baseline scans non-interleaved, which zune-jpeg 0.5.15
decodes wrongly with 4:2:0 chroma (zune-image#419), as Save for Web
already works around.
- engine: a `jpegFormat` save param (file.saveACopy, Batch, Image
Processor, Layers to Files and every SaveOpts user; anything but the
three names is BadParams before writing) and a shared 0–12 -> 1–100
`jpeg_quality()` that maps NaN/inf to 100.
- ui-egui: `jpeg_options_ui` (Quality 0–12 with Low/Medium/High/Maximum
presets, Format Options), parked like Targa Options. It starts at the
opened JPEG's own quality (`file_encoding`, #4032), else the Export
preference; left there, OK writes that quality exactly and the step
records no `quality`. `SaveChoices` (Targa bits + JPEG) replaces the
bare `tga_bits` through file.save / file.saveAs / app.save, replay and
Save a Copy; automation never prompts. `write_answered_save` is shared
with Targa Options. `park_at` + `Start` let any save seed the prompt.
A File › Save that confirms the document's own flat JPEG is still
journalled as a plain `file.save` (#3531).
- CLI: `--jpeg-format`.
- i18n: five new strings in all 20 catalogs (#4330's duplicate de/es/zh
`Low`/`High` rows dropped: main has them since #4008).
- Docs: book raster-formats JPEG bullet, control protocol, file-format
parity, gaps G10, target-app parity; scorecard FILE-215-19 done.

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.
* Check deep EXR tile count tables against max_alloc
A deep tile's sample-count table was decompressed at the header's full tile size with no
budget check, so a 20 KB file could build a 4 MiB table and a scratch copy under a 1 MiB
max_alloc. Try that size only when max_alloc has room for both; otherwise read the clipped size.
Fixes#4958.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* Keep deep EXR decompression within the size it was admitted at
The count-table check admits the table and its scratch copy, 2x the table, but Vec doubling
gave a 4 MiB ZIPS table 8 MiB of capacity (a 3 MiB RLE table 4 MiB), so an admitted table
and its copy could take 3x. Grow the decompressed buffer by doubling capped at the expected
size, inflating straight into it, and allocate it and the scratch copy fallibly.
Tests: decompressed buffers never reserve past the expected size; a near-maximal tile with a
clipped table decodes under every budget; per-tile admission; half and uint channels after
full-size tables; the 8 MiB boundary for uncompressed tables too.
Refs #4958.

* Tests: show deep tile tables are admitted one tile at a time
The 17x17 image in 16x16 tiles had an interior tile, which never reaches the max_alloc check,
so only three edge tables (6 KiB) were checked against the 8000-byte budget and a check that
summed admissions across tiles still passed. Use a 48x1 image instead: its three tiles are all
edge tiles, and under 4096 bytes a summed check fails at the third tile.
Refs #4958.

* Complete deep EXR count-table allocation admission
Account for scratch space on clipped and interior compressed tables while preserving raw-table budgets. Borrow packed input before admission and make initial RLE reservations and raw copies fallible.
Add single-channel admission boundaries, raw fallback controls, and hostile-size borrowed-read regressions.
* ci: run deep EXR regressions independently
* Drop the separate deep EXR CI job
It was added so these tests could run while main's workspace suite was
failing. Main is green again, and the regular test jobs run them.
This reverts commit 5aa4869b45.

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.
An entry's value only has to lie inside the file, so many Exif entries can
point at the same bytes: a 62 KB TIFF with 1,000 such entries made the reader
copy 50 MB (and the block writer copy it again), on every TIFF import and on
export of a document carrying an EXIF block.
read() now has a copy budget shared by IFD0's descriptive tags and the GPS and
Exif directories: at most 4 MiB, and never more than the stream's own length,
since the values of a well-formed stream are distinct bytes of it. An entry
that does not fit is left out and later, smaller ones are still kept; the
small directories are read first so a huge maker note cannot crowd out the
GPS position. Maker notes of 200 KB and 1 MB round-trip as before.

* TIFF: read and write CIE L*a*b* (CIELab, ICCLab); Lab documents stay Lab
Photoshop saves Lab documents as CIELab TIFFs (PhotometricInterpretation
8, a* and b* signed), which PhotoCraft could not open, and PhotoCraft
saved Lab documents as sRGB TIFFs.
- codecs: a Lab channel layout (Lab, LabA) holding a* and b* as
PhotoCraft's Lab documents do ((a + 128) / 255; 16 bits like the PSD
importer), with its own Lab <-> sRGB conversion (same formulas as
photocraft-color; codecs stays standalone) for formats without Lab,
which now warn LabConverted.
- TIFF read: CIELab and ICCLab (8 and 16 bits, alpha) are handed to the
tiff crate as RGB and labelled Lab; a* and b* are converted from the
file's encoding (signed a / 256a, or offset).
- TIFF write: Lab and LabA as CIELab, as Photoshop writes it; float Lab
is written with 16 bits (DepthReduced).
- io: a Lab TIFF opens as a Lab document; a Lab document with one plain
layer is written to TIFF in Lab (other formats still use sRGB).
Photoshop 2025's Lab TIFFs open with the colours Photoshop shows (its
own RGB conversion matches within one level at 8 bits and exactly at 16
bits), and Photoshop reads PhotoCraft's Lab TIFFs back with the same
L*a*b* values.
Fixes#4936
* 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.
* PSD: write tiff blocks without copies, inflate merged ZIP once
- ImageSourceData::to_bytes writes the global mask and global blocks
straight from the model with 4-byte alignment instead of cloning each
block (data included) to set its padding. Same bytes.
- The tiff transcoder's nested regions and blocks write into the parent's
buffer (taken and handed back, error or not) instead of building their
own output and copying it up per nesting level. Bodies that fail or are
not transcoded are truncated before being copied as stored or dropped.
Same bytes.
- PsdFile::from_bytes_and_merged decodes the merged image with the parse
when asked: a ZIP stream is inflated once (the decode's stream check is
the parse's); the parse-only check runs only when the decode fails, to
keep from_bytes' errors. PSD import uses it with merged_needed.
- PsdBuilder::composite documents that Gray/CMYK composites stay straight.

* Content-Aware Fill: measure a thin hole by its thickness, not its bounds (#1366)
Removing long, thin objects (coiled guitar strings, wires) left their
outline as darker and lighter blotches and copied pieces of other strings
into the fill. The pyramid shrank until the hole's bounding box was four
patches across: for a string across the image that is a level where the
hole has swallowed its surroundings, so the matches found there copy
whatever looks like the blur, and the finer levels (refine-only for wide
bounds) keep them.
A hole at most a quarter as thick as its bounds are long now counts as
thin: the pyramid stops while it is still about two patches thick, and
that level starts from a membrane across it (over a few pixels, the
surroundings themselves) instead of the onion peel, whose exhaustive
search is what made a shallow pyramid unaffordable. Compact holes are
unchanged bit for bit.
Refs #1366
* perf(compose,gpu): effect caches reserve tile addresses instead of pinning layers
Effect map cache entries kept a clone of their layer (a deep clone for groups) so the tile addresses the cache key hashes couldn't be reused. That kept an edited or deleted layer's pixels alive, uncounted, until the entry was evicted. Keep a Weak to each hashed tile instead: it reserves the address without keeping the pixels. The GPU compositor's styled-group pins and shape-source tile snapshots do the same. Part of #4530.

* fix(history): count snapshot-only tiles against the history budget
History panel snapshots outlived every budget: a Merged Layers snapshot is a full flattened copy that neither the history budget, the GPU budget's document bytes nor Purge accounted for. Trim now counts the tiles only snapshots hold as fixed cost, the GPU budget includes them, and Purge > Histories no longer reports tiles a kept snapshot still holds as freed. Part of #4530.

* Content-Aware Fill: every part of a thin selection keeps its surroundings (#1366)
Two more causes of ghosts when removing strings and the small knobs
selected with them:
* Auto sampling summarises the selection's surroundings by a few
clusters. Around a long selection those come from the strings'
surroundings, so a small part elsewhere (a tuning knob in a differently
coloured corner) lost its own surroundings and was filled from far away
in another colour. Around a thin selection the Auto area now always
reaches as far as the selection is thick.
* The membrane that starts a thin hole now starts a patch radius out, past
the anti-aliased fringe or halo that a selection drawn close to the
object leaves outside it.
Refs #1366
* Content-Aware Fill: peel a thin hole where that stays affordable (#1366)
Starting every thin hole from a membrane smoothed Spot Healing on film
grain (spot_healing_keeps_film_grain_through_overlapping_strokes: grain
9.0 against 12.1 around). The onion peel copies the grain; it was only
given up because its exhaustive search is too slow on the big level a
long thin hole stops at. It now starts the thin hole whenever hole cells
times sources stay within 2^28 comparisons, and the membrane only beyond.
Refs #1366
* Select Subject: keep subject parts coloured like the backdrop, leave enclosed gaps open
Users on #2788 reported Select Subject dropping clothes that are close in
colour to a plain wall and bridging the gap between an arm and the torso.
Both come from the same place: the saliency pass labels low-contrast parts
of the subject as background, the background colour model then learns
them and explains them away, and the final blind hole fill closes every
enclosed gap up to 5 % of the mask.
Two changes in crates/algo:
- A second GrabCut pass whose background model only knows the backdrop. A
colour model fitted to the image frame (minus a margin around the
salient blob, in case the subject runs out of the picture) marks every
pixel it explains as probable background; the blob and whatever the
backdrop cannot account for start as probable foreground. Only
components that touch the first pass's result survive.
- Hole filling that consults the colour models: specks (<= 0.2 % of the
mask) always fill, larger holes up to 5 % fill only when their pixels
fit the foreground model better than the background's.
Tests: two regressions (a cream-shouldered figure on a near-white wall
keeps its shoulders; a ring keeps its backdrop-coloured hole open), plus
ignored timing and picture-dump helpers. The 6 MP first run goes from
about 100 ms to about 200 ms on one core; the P29 repeat path is untouched.
* Keyboard shortcut sets: Set menu, New Set, Save, Delete, .kys Export and Summarize (K2)
Edit › Keyboard Shortcuts gets Photoshop's set management. A set is a saved copy of the
bindings (Preferences.shortcutSets, the one in use in shortcutSet; "" is PhotoCraft Defaults),
and the Set menu shows "(modified)" when the bindings differ from it. New Set…, Save and
Delete wait for OK like the rest of the dialog. Export… writes the dialog's bindings as a .kys
file (commands then tools, Photoshop's macOS key spelling), each row carrying our id as pc-id
so PhotoCraft imports its own sets back exactly, whatever the label; Summarize… writes
Photoshop's HTML list of every bound command by menu.
edit.keyboardShortcuts takes useSet (before the call's edits), saveSet, deleteSet, sets and
activeSet (after them), exportKys and summarize; every reply reports the sets, the set in use
and whether it is modified. Bad names, keys or counts are errors that change nothing.
* .kys import: tool keys and sets saved on Windows (K3)
Photoshop's <tool> rows now import: each matches our tool by name (our tool names are
Photoshop's) or by pc-id in sets PhotoCraft exported, and a letter other than the tool's own
becomes its override, while its own letter keeps the tool cycling with the others (#5036).
A set saved on Windows spells the primary modifier Ctrl where a Mac set writes Cmd and keeps
Control for the Control key. A set with no Cmd or Opt anywhere but some Ctrl is read as a
Windows set, its Ctrl as our Cmd: Ctrl+L is the Cmd+L default, not a Control-key override that
would also mean Control on a Mac. The import reports `windows`.

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.

source_size_probe decoded every embedded file other than PSD/TIFF/PNG/JPEG
in full just to learn its size. photocraft_codecs::probe_size reads the
size from the same decoders' headers (WebP chunks, the image crate's
GIF/BMP/TGA/ICO/QOI/HDR headers, flat EXR part headers), with the same
limit checks and the EXIF quarter-turn swap, so it agrees with decode
wherever decode succeeds. Deep EXR, AVIF and anything else still decode.

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.
A renderer's data window is its crop of the frame; the composition lives
on the whole display window (our MY27 renders: data 1782x1267 at
(1109,1100) inside a 4000x3000 stage). decode_deep now validates the
display window against the limits and reports it as stage + origin on
DeepImage; flatten pads the composed region to the stage at its offset
(transparent elsewhere) and tags the image with a DisplayWindowStage
warning. Files without a usable display window open as before.
Includes a cropped-deep generator and a stage/offset oracle test.
A flat TIFF dropped EXIF on export ("EXIF not supported") and ignored it
on import. TIFF is EXIF's own container: IFD0 points to the Exif (34665)
and GPS (34853) directories and holds the descriptive tags.
- Export: the EXIF block's Exif and GPS directories are written as
directories outside the page chain, IFD0 points to them, and IFD0's
descriptive tags (ImageDescription, Make, Model, Software, DateTime,
Artist, Copyright) are added unless the text metadata already wrote
them. Values are copied as bytes, reordered to the file's byte order,
so unknown tags survive.
- Import: a classic TIFF with an Exif or GPS directory gets an EXIF
block built from them and IFD0's descriptive tags.
- TIFF's format caps now include EXIF. Layered TIFFs keep EXIF as
resource 1058 as before (read back unchanged); the layered importer
already preferred the TIFF's own EXIF when there is one.
exiftool and Photoshop 2025 read the Exif and GPS tags of such a TIFF.
Fixes#4875
pHYs holds whole pixels per metre, so 300 ppi is stored as 11811 and
read back as 299.9994 (72 as 72.009). The ppi read is now the whole
number that rounds to the stored value when there is one, as Photoshop
reads it; other values stay as they are.
Fixes#4855
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.
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).

Each Cryptomatte RGBA set stores two (ID, coverage) ranks, (red, green)
and (blue, alpha), but only red/green were read, so every second rank
was lost and mattes got holes at edges and overlaps. Suffixes were also
matched case-sensitively, missing Blender's .R/.G/.B/.A.
Stream channels now carry a rank (0 red/green, 1 blue/alpha), suffixes
match in any case, and decode stores each channel at slot*2+rank
(bounds-checked), still sorted by coverage. The allocation check counts
four channels per set.

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.

Add a pure-Rust DICOM reader: the file meta group's transfer syntax
(implicit VR little-endian, explicit VR little/big-endian), MONOCHROME1/2
and RGB/YBR_FULL, 8/16-bit allocated samples, interleaved or planar,
BitsStored/HighBit scaling and signed pixel representation. Compressed
syntaxes, sequences, multi-frame data and other photometric interpretations
are refused with Unsupported/Malformed, never wrong pixels. DICOM is
read-only; .dcm/.dicom/.dc3 join the open filters (and .pcx is added to the
web filter, where it was missing).
read_layer decoded every part and picked one; use a first-valid-layer reader
that declines all other parts. Cryptomatte now goes through read_meta and
read_layer. Enable exr/rayon on native targets.
