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 * PSD: a smart object's filter mask shows when the file opens Photoshop stores a smart object's layer pixels with its filters applied but not its filter mask. When it composites, it mixes the unfiltered pixels (cached in FEid) back in through the mask. We showed the stored pixels as they were, so a PSD whose smart filter has a mask opened with the filter everywhere. Only after something re-rendered the smart object did the mask appear, because our re-render mixes it. - compose::filter_mask holds the mix, moved from the engine, and its inverse. - Import decodes the unfiltered pixels from FEid (smart_map::unfiltered_from_item) and keeps the mixed result as the smart object's pixels, as the engine's re-render does. - Export writes the layer record the way Photoshop does: unmixed with the unfiltered pixels it writes (or keeps) in FEid, so Photoshop mixes back to what the document showed. Transparent pixels stay empty. Photoshop oracles: sf-filter-mask-hard, sf-filter-mask-gradient and sf-stack-blend-and-mask pass (145 -> 148 of 258); floor 145 -> 148. psd-tools and io corpora unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * DNG: decode lossy (JPEG-compressed) DNG tiles (FILE-215-11) DNG 1.4 lossy JPEG (compression 34892) stores each tile or strip as a baseline-DCT JPEG of 8-bit samples: a gray stream for CFA data, a YCbCr stream for three-sample LinearRaw. The decoder arm from #2021 read the streams but widened every sample by 257, so the values no longer matched the file's levels: an 8-bit WhiteLevel (or its default, 255) clipped everything to white and a 256-entry LinearizationTable was indexed past its end. It also required the JPEG frame to match the clipped row count, which rejected the padded edge tiles real tiled files carry. The arm is now `lossy_jpeg()` in sensor.rs. The decoded 8-bit values are the stored samples, and BlackLevel, WhiteLevel (default 255 for 8-bit data) and the LinearizationTable apply to them exactly as for every other compression. A tile may be coded at the full tile size (edge tiles padded, as the spec says) or at the image's row count; a strip at its row count; the width must be the segment's. BitsPerSample must be 8 and the JPEG's component count must equal SamplesPerPixel (1 or 3); anything else is an error, never a silent conversion. The frame header is checked before any pixel is decoded and the JPEG decoder's own size cap is the segment the IFD declares (already charged against the limits), so a hostile SOF cannot size a buffer past the tile. testgen writes true 8-bit lossy fixtures (`LossyJpegTiles`, and strips via the new `LossyJpegStrips`), accepts pre-encoded `lossy_segments` for hostile-input tests, exposes `baseline_jpeg()`, and leaves WhiteLevel out when `white` is 0. The DNG tests cover CFA and LinearRaw RGB from tiles and strips at 37x23 (partial edge tiles, a short last strip), the default white level, black/white scaling and a LinearizationTable against the uncompressed path, and hostile inputs: a truncated tile, frame-size and component-count mismatches, a 65535x65535 SOF under default and tight limits, a tile over the allocation budget, and 12/16-bit or 4-sample files. The hostile mutation set gains a lossy CFA and a lossy LinearRaw file. The parity doc's DNG row is updated; the scorecard row is left for the coordinating branch. * 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. * Vector: bound flattening memory, keep over-budget dashes, cheaper edge build (#5195) - flatten: a path's flattened points are capped at 1 << 20; past it every curve keeps a proportional share of its pieces (at least one), so hostile handles from files (vmsk, SVG, effect outlines) cannot exhaust memory. fill_rasterizer flattens the whole path under one budget. - stroke: past the dash step budget (or below coordinate precision), dash_polyline keeps the dashes made so far and draws the rest solid instead of dropping the stroke. Open polylines are no longer copied. - raster: coordinates are clamped to +-1e15 and edges with a non-finite slope (vanishingly short) are skipped, so huge finite coordinates no longer produce NaN coverage. fill_rasterizer sorts edges once instead of after every component (stable sort, identical order). - Cleanups: dead miter `half`, dead loop-length check in trace_mask, shared mask render body, map_knots helper, shared straight-segment test. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * PSD: cap pattern memory across a parse, reject mixed-depth pattern channels (#5198) - Patterns: one PatternBudget (decoded bytes + zero padding) is shared by every pattern of a block, a .pat file and the pattern blocks of one document; .abr patt sections are charged to the samples' budget. - Patterns: a channel whose depth differs from the first is rejected (the parsed pattern could not be written back). - Slices: descriptor numbers no longer wrap; out-of-range ids are no id, coordinates clamp to i32, and a v6 trailing entry without a usable id attaches its outsets to no slice. - LayerInfo::unpadded_len is computed from field sizes instead of serializing every record into a scratch buffer. - abr desc presets are moved out instead of cloned; UnFl and shmd counts use the bounded preallocation; ImageData::decode_channel (decoded every plane to return one, unused outside its test) is removed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Vector: bound stroke outline points (#5211) - stroke_polygons dashes all lines first, then counts round caps and joins. When their full-resolution tessellation would exceed 1 << 20 outline points, every round cap and join gets the same smaller segment count (down to 4 per circle, 1 per join; area-exact radius kept). Strokes under the budget are unchanged; no piece is dropped. - The dash step budget (100000) is now shared by all lines of a stroke instead of per polyline, so many subpaths cannot multiply the dash (and cap) count. Past it the rest is drawn solid, as before. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 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`. * cargo fmt the extension lists Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> --------- Co-authored-by: Gert Pellin <gert@pellin.be> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: Fabio Lissi <fabio.lissi@gmail.com> Co-authored-by: Vikram Bhaskaran <vikram.bhaskaran@outlook.com> Co-authored-by: vangel76 <vangel1976@googlemail.com> Co-authored-by: Finn Newick <finnnk@gmail.com> Co-authored-by: Brandon Thomas <echelon@gmail.com> Co-authored-by: Diego Chagas <drochachagas@gmail.com> Co-authored-by: Tanish Manku <tmanku.dev@gmail.com>	2026-10-15 00:58:45 -04:00
3 people	0002d861ee	fix(io): read CS2 placed layers that carry only a PlLd block (#2465) (#4268) ... Photoshop CS2 predates SoLd: its smart objects have a PlLd (plcL) block alone, with the embedded file in a global lnkD block. Import only read SoLd/SoLE, so such layers got an empty source id and Edit Contents said "the smart object's contents are unavailable". Parse PlLd from the Adobe PSD spec (unique id and the 8 corner doubles). PlLd stores no source size, so the transform takes it from the embedded file's header (linked::source_size_probe: PSD, TIFF, PNG and JPEG headers, any other image decoded flat by photocraft-codecs). It never imports the file as a document: a layered TIFF can carry PSD layer data whose lnkD holds another file, so that would nest without bound. Without the file, 100 % scale is assumed. source_geometry moves to linked.rs. Non-parallelogram corners give the projective placement as for SoLd. An unreadable PlLd is reported as a warning. The PlLd corners are the same placed quad as SoLd's Trnf, so they frame the same source-space box (#3677, blocks::placed_frame): the bounding box of a single-patch custom warp's 16 control points, which may spill past the source, else the source rect. corners_affine now maps such a frame onto the corners and is shared by parse_smart and plld_transform, which is the inverse of smart_map::quad_points (what plld_bytes writes): affine corners frame placed_frame(warp), projective ones the source rect. A custom warp's box needs no source size, so a spilled mesh is placed right even without the embedded file. corners_affine refuses non-finite corners or an empty frame (identity, as before). CS2 can warp a smart object, and PlLd keeps that warp after the corners (u32 warp version, then a versioned warp descriptor). It is read with the same code as the SoLd warp (warp_of), so a re-render from the now available source (Free Transform, Image Size, mode changes) stays warped. A stored warp that can't be read leaves the contents unavailable, keeping the warped pixels, with a warning. An edited PlLd-only layer (moved, transformed, warped, filtered or given other contents) is saved like any other smart object, SoLd plus a regenerated PlLd, with its current placement; an unedited one keeps its record verbatim, as does one whose file isn't embedded (its id is never read as a disk path). plld_edited compares against plld_transform with the record's own warp, so it uses the same frame as import and as the writer. A layer with both SoLE and PlLd is read from SoLE. Tests: PlLd round trip and malformed input (truncation, bad magic, oversized Pascal length, NaN) in blocks.rs; PlLd warps round trip through plld_bytes (preset, custom mesh, identity, none) and unreadable warps are reported as such; a PlLd whose custom mesh spills past the source places like the equivalent SoLd, with and without the source size; PlLd-only layers with a missing file, a broken record, a warp or an unreadable warp; a spilled-mesh PlLd-only layer imports with the SoLd layer's placement and an unedited one saves its PlLd verbatim (no SoLd) and reopens in place; and engine tests that rewrite an export into the CS2 layout (no SoLd, lnkD with version-2 liFD items) and check transform, contents, re-render, Edit Contents, and that a warped smart object re-renders warped. source_size_probe has header tests for each format and malformed JPEG marker walks.

Scott MacdonaldandClaude Opus 5.5	590bec7998	feat(io): import Photoshop Displace smart filters with their embedded map (#3680) ... A Displace smart filter (Fltr class `Dspl`, filterID 1148416108) was not in the modelled filter list, so it became psd.unsupportedFilter and rendered as a pass-through. Mockup PSDs that bend a replaceable design over fabric (a design smart object with Displace then Gaussian Blur) rendered flat. Photoshop stores the displacement map inside the filter: `DspD` (raw data) holds u32 LE height, u32 LE width, u16 LE mode 3, then two 8-bit planes (horizontal, vertical) and padding, next to HrzS/VrtS (scale %), DspM (StrF stretch / Tile), UndA (RptE repeat / WrpA wrap), EmbF and DspF (an alias to the author's map file, usually unavailable). The filter now maps to filter.distort.displace. As for Camera Raw, the whole item (with the map) is kept as hex in `__displacePsd`, so it re-renders, survives .pcraft and is written back to PSD with only the editable settings and blending replaced. params_for resolves the embedded map, so the smart filter re-render applies it, stretched over the document canvas (the bounds smart filters already pass). Another mode, a missing or truncated map, or unknown enum values keep the item opaque as before. The map parser uses checked sizes and caps maps at 2^26 pixels. Tests: displace_map unit tests (layout, every truncation, hostile and corrupted headers, round trip, edited settings, opaque fallbacks, bad exports) and smart_psd::displace_psd_filter_renders_with_its_embedded_map (8/16/32-bit: renders displaced, PSD export/import and .pcraft keep it).
