Every format Photoshop 2026 (27.11.0) reads or writes, with PhotoCraft's support, fidelity and
tests. Photoshop's list comes from its Info.plist CFBundleDocumentTypes, the PiPL read/write
flags of Contents/PlugIns/Required/File Formats, and format names in the main binary (Open/Save
As behaviour from Adobe's documentation where the bundle doesn't say). Ours comes from
crates/codecs/src/format.rs (capability table), crates/io/src/lib.rs (import/export
dispatch), crates/psd, crates/raw, crates/heif, crates/affinity. More detail on our side:
raster formats, PSD/PSB,
OpenRaster, Paint.NET.
Summary. By count, 13 of Photoshop's 31 formats are fully supported in the directions Photoshop supports them, 4 partially (48%, measured). Weighted by use (PSD/PSB 40%, JPEG 15%, PNG 15%, TIFF 10%, camera raw 8%, WebP/AVIF/ HEIF/JXL 6%, PDF 3%, everything else 3%), presence is ~80% and ready-for-real-work ~60%: PSD is broad but not yet reliable against Photoshop (gap G1), and Photoshop PDF, AVIF read and JPEG XL are missing (gap G10). Remaining: 300–500 h including PSD fidelity.
Photoshop's formats
| Format | Photoshop | PhotoCraft read | PhotoCraft write | Fidelity and tests |
|---|---|---|---|---|
| PSD | R/W | yes | yes | 1/8/16/32-bit; Bitmap, Gray, Indexed, RGB, CMYK, Multichannel, Lab, Duotone; layers, groups, masks, vector masks, adjustment and fill layers, effects, text, shapes, smart objects (SoLd/lnk2 with their warp: the bend presets, a custom mesh and, since #4112, Cylinder; CS2 PlLd/lnkD read with their warp, kept as is or re-saved as SoLd once edited), smart filters (53 mapped, among them Invert, the Distort filters but Shear, Clouds, Difference Clouds, Fibers and Lens Flare, plus Hue/Saturation, Perspective Warp, Filter Gallery with Chrome and a Camera Raw subset, rest verbatim), slices, comps, Advanced Blending, each layer's XMP packet (layer.xmpMetadata). Oracle floors: Photoshop-authored 190/258, io 148/170, psd-tools 249/309; round trip ≥ 169/170, 308/309, 258/256. Known failures: #1281, #2469 (#2374, text layers, closed 2026-10-10; #2465, CS2 PlLd-only smart objects, fixed 2026-10-12) |
| PSB | R/W | yes | yes | Auto-switches above 2 GB (REL-212-2); generated 20 MP, 150-layer, 2 GB PSD and 4.4 GB PSB fixtures opened, saved and re-opened by io tests/it/large_files.rs (FILE-216-2, 2026-10-13; the 4.4 GB PSB opens on Windows); > 4 GB from the app's File › Open on Windows: #375 |
| Cloud PSD (.psdc) | R/W | no | no | Out of scope (Adobe cloud) |
| TIFF | R/W | yes | yes | 8/16/32f, Gray/RGB/CMYK, BigTIFF, every IFD, banded parallel decode; layered TIFF both byte orders, including Photoshop mixed-order type blocks (#4758); LZW/ZIP for scripted saves by tiffCompression; undecodable type keeps saved pixels (FILE-215-7: extra alpha channels not written) |
| JPEG | R/W | yes | yes | 8-bit Gray/RGB/CMYK, ICC/EXIF/XMP; Save keeps the opened file's quality (estimated from its quantisation tables, #2399); File › Save, Save As and Save a Copy ask JPEG Options: Quality 0–12, starting at the opened file's quality or else the Export preference, and Baseline ("Standard") / Baseline Optimized / Progressive; scripts pass quality/jpegFormat, the CLI --jpeg-format (FILE-215-19). Baseline Optimized fits the Huffman tables only at 4:4:4 (Gray, CMYK) or progressive: RGB is written 4:2:0, which zune-jpeg 0.5.15 decodes wrongly with fitted tables, as in Save for Web. No Matte, progressive Scans (3–5) or size preview |
| PNG | R/W | yes | yes | 8/16-bit, ICC/text; APNG first frame only; alpha channels on open (#2225); palette PNGs open in Indexed Color mode with their transparent entry (#4804); Save keeps a stereo PNG's sTER pairing (#6063) |
| GIF | R/W | yes | yes | File › Open keeps the first frame; New Video Layer from File and Video Frames to Layers take every frame, with the timeline rate from the delays (#572). Per-frame delays and keeping the frames in .pcraft are not done |
| BMP | R/W | yes | yes | 8-bit; palette BMPs open in Indexed Color mode and Indexed Color documents save as palette BMPs (no transparency) |
| WebP | R/W | yes | yes | Lossless and our own lossy VP8 encoder; ICC/EXIF/XMP; Save keeps an opened file lossy (at its quality) or lossless (#2399). File › Open keeps an animation's first frame; New Video Layer from File and Video Frames to Layers take every frame, with the timeline rate from the durations (#1198) |
| AVIF | R/W | no (#463) | optional feature, off by default | |
| JPEG XL | R/W | inside DNG only | no | |
| HEIF/HEIC | R/W(HEIF) | yes (pure-Rust heic-rs, heif feature, on in releases) |
no | 8/16-bit |

| Targa | R/W | yes | yes | 8-bit |
| Photoshop PDF | R/W | no (#2541) | yes, one flattened page (Save As / Save a Copy / CLI, #3401; also print and artboards-to-PDF) | No vector/text PDF, no multi-page save, no PDF presentation, layers are not preserved (FILE-215-10); read still missing (#2541) |
| Photoshop EPS, DCS 1.0/2.0, EPS TIFF/PICT preview | R/W | no | no | |
| Generic EPS / AI | R (rasterize) | no | no | |
| SVG | R (rasterize) | yes, as editable shape layers or a vector smart object | no | Better than Photoshop for editing; gradients approximated (FILE-215-9) |
| JPEG 2000 | R/W | no (#1047) | no | |
| Cineon / DPX | R (DPX), R/W (CIN) | DPX: luma, RGB, RGBA at 8/10/12/16 bits, both byte orders (#1049); Cineon: 10-bit gray/RGB | DPX: 8/10/12/16 bits (dpxBits, --dpx-bits); Cineon: 10-bit log gray/RGB (Save As .cin) |
Writes DPX, which Photoshop only reads; header fields (creator, project, copyright, transfer, frame rate, time code…) round-trip; a Cineon frame saved as Cineon keeps its 10-bit code values; no RLE |
| DICOM | R/W | yes (#1048) | no | Read-only, uncompressed syntaxes: MONOCHROME1/2, RGB, YBR_FULL |
| PCX | R/W | no | no | |
| Pixar | R/W | no | no | |

| Scitex CT | R/W | no | no | Legacy |
| Photoshop Raw (.raw) | R/W | no | no | |
| Camera raw (via Camera Raw 18.7) | R | partial | – | See below |
Camera raw
Photoshop opens raws through Camera Raw 18.7 (the bundle registers cr2, crw, dcr, dng, erf, mos, fff, 3fr, mef, mfw, iiq, nrw, rwl, srw, mrw, nef, orf, pef, raf, srf, x3f; Camera Raw itself supports many more, including CR3).
| Camera format | PhotoCraft | Evidence |
|---|---|---|
| DNG (incl. LJPEG, lossy JPEG and JPEG XL tiles) | yes | 2026-10-13: lossy DNG (DNG 1.4 compression 34892: 8-bit baseline JPEG tiles or strips, CFA and LinearRaw, partial edge tiles) decodes to the stored samples, which go through LinearizationTable / BlackLevel / WhiteLevel (default 255) like every other depth; crates/raw/tests/it/dng.rs lossy_jpeg_* (FILE-215-11, lossy DNG part; no lossy file in the raw corpus yet) |
| Canon CR2 | yes | |
| Canon CR3 | detected, unsupported | crates/raw/src/lib.rs:219 |
| Nikon NEF/NRW (lossless, lossy) | yes; "lossy after split" no | #50; D5100 and D90 image areas measured (14-bit NEFs); D4 profile levels follow the sample depth (12 and 14 bit); validation |
| Sony ARW/SR2/SRF (incl. compressed) | yes | |
| Panasonic RW2, Pentax PEF | yes | |
| Olympus ORF | uncompressed only | |
| Fujifilm RAF (Bayer and X-Trans) | uncompressed only; no Fuji colour calibration | |
| Others (CRW, 3FR, IIQ, X3F, SRW, MRW, ERF…) | embedded preview only | |
| .xmp sidecars, highlight modes, raw preferences | missing | FILE-215-11 |
| Camera Raw as a PSD smart filter | partial | 2026-10-07: WB, Light/Presence, curves, HSL, grading, detail, grain, vignette mapped (FILE-215-12) |
2026-10-11: on #2135's embedded-JPEG rendering work, open-time Camera Raw tuning preserves the fitted rendering while changing Exposure, Temperature and Tint. Default tuned import matches normal import exactly; output remains full-resolution 16-bit ProPhoto. This improves appearance when a usable preview is present, without adding a measured D5100 colour profile. Counts and the G14 estimate are unchanged.
Formats Photoshop doesn't have (ours only)

Saves a 2D texture uncompressed (BGRA, BGRX, luminance with or without alpha) or BC1–BC3 with the legacy header, optionally with its full mip chain (box filter); Save As and Save a Copy ask (DDS Options), scripts pass ddsCompression and ddsMipmaps (--dds-compression, --dds-mipmaps on the CLI). Cubemaps, arrays, volumes and BC4–BC7 are refused (#1327). Photoshop needs a plug-in |

Affinity import notes (moved from roadmap.md)
2026-10-08: Affinity .af, .afdesign, .afphoto and .afpub documents (container versions
8–12) open natively (format notes): pages and artboards, layers
and groups, curves and geometric shapes with fills, gradients and strokes, text as type layers,
placed images as smart objects, pixel layers and masks, as an 8-bit RGB document without a source
save path. Measured against the thumbnail Affinity embeds in each file, 21 pinned public documents
(cargo xtask corpus --affinity) differ by 0–4.6 of 255 on average. Layer effects, adjustments,
live filters, brush strokes, special shapes, master pages and CMYK/Lab/16-bit document colour are
approximated or left out, each with a warning; damaged or unknown files fall back to the embedded
preview. Affinity writing is not implemented: no Affinity installation was available to check
written files, so .af export stays unsupported.
2026-10-10: current .af artboard properties (phrp/aprp) are recognized alongside the
legacy flag, including converted curve boards. Synthetic two-board regressions check separate
bounds, overflow clipping, .pcraft/PSD board and pixel round trips, and moving one board with its
children through undo/redo. Nested boards remain masked groups; rotated/curved board outlines
still import at their bounding rectangle.
2026-10-09: corpus/affinity/ now has 39 pinned documents and 21 PNGs (20 rendered references and
one bitmap-fill texture): the prior 21 public documents plus 18 CC0 samples for #1606. The new
samples compare against their exported PNGs;
mean differences range from 0.44/255 (conical gradients) to 86.05/255 (RGB/32 reduced to 8-bit).
Clouds, hearts, cogs, callouts, arrows, double stars, tears, crescents, diamonds and circular segments
now import as parametric shapes; the special-shapes sample measures 5.68/255 against its PNG. The
remaining gaps in #1606 stay tracked with per-sample corpus ceilings.

Revision history
| Date | Change | Summary |
|---|---|---|
| 2026-10-22 | minor | 32-bit Hue/Saturation as Photoshop does it: the raised saturation isn't clipped (saturated colours leave 0..1), the chroma is scaled around the lightness by Photoshop's saturation factor (measured at every whole percent), so colours at or above lightness 1 keep their hue, and Colorize builds its colour with the saturation times 1 − |Lightness| (8 and 16 bits unchanged): photoshop rgb32 hue-saturation and hue-saturation-colorize pass; Photoshop-oracle floor 188 → 190 of 258 (#5781) |
| 2026-10-19 | minor | JPEG Options on File › Save, Save As and Save a Copy (FILE-215-19 partial: no Matte, progressive Scans or size preview) |
| 2026-10-18 | minor | Scripted TIFF saves take tiffCompression (none, LZW, ZIP), and the CLI --tiff-compression (#5301) |
| 2026-10-17 | minor | .atn: a recorded Save As imports with its format and file (file.saveAs, file.saveACopy for As a Copy) instead of as a plain Save that wrote over the played file, #7102; folder destinations stop playback until #5430 |
| 2026-10-17 | minor | .atn: Apply Layer Comp by name maps to layerComp.apply and exports as applyComp (#7101) |
| 2026-10-15 | minor | Legacy PSD point-text placement is refined after font resolution using the rendering engine; centered/right alignment keeps its layout offset, while valid Txt2 frames remain authoritative. Synthetic alignment, font-context and round-trip regressions cover this fallback. |
| 2026-10-15 | minor | Cineon write: Save As .cin stores 10-bit log gray/RGB frames (Cineon 4.5 header, three samples to a 32-bit word); a Cineon frame saved back keeps its code values |
| 2026-10-14 | minor | 32-bit Hue/Saturation as Photoshop does it: the raised saturation isn't clipped (saturated colours leave 0..1) and the slider is cut to whole 8-bit levels, and Colorize builds its colour with the saturation times 1 − |Lightness| (8 and 16 bits unchanged): photoshop rgb32 hue-saturation and hue-saturation-colorize pass |
| 2026-10-14 | minor | Lab documents round each adjustment layer's result on the stored L, a, b to whole samples, as Photoshop stores them (the native Lab path): photoshop lab8 curves.psd passes |
| 2026-10-15 | minor | PSD smart filters: Clouds, Difference Clouds, Fibers and Lens Flare open as editable filters with their seeds, colours and lens, and save like Photoshop (checked against a Photoshop 27 file); render filters on a smart object work within the object, so a flare sits where Photoshop puts it |
| 2026-10-15 | minor | DDS textures save (#1327): uncompressed or BC1/BC2/BC3 (DXT1/3/5) from a clean-room block encoder, optional box-filtered mip chain, legacy header; DDS Options in Save As and Save a Copy, ddsCompression/ddsMipmaps for scripts, the CLI and MCP |
| 2026-10-16 | minor | PSD smart filters: Perspective Warp (perspectiveWarpTransform: vertices, warpedVertices, quads of vertex indices, document pixels) opens as layer.smartObjects.perspectiveWarp, one plane per quad, and re-renders warped; save writes the original item with only the geometry rewritten, or a new one in Photoshop's layout; inconsistent descriptors stay verbatim (FILE-215-2, #6268) |
| 2026-10-16 | minor | PSD smart filters: Hue/Saturation (HStr: Clrz, Adjs = master Hst2 plus one per edited range with LclR and its four range sliders, all longs, measured on a Photoshop-saved file) opens as image.adjustments.hueSaturation, re-renders with the smart object and saves in Photoshop's layout; layouts outside it stay verbatim (FILE-215-2, #6267) |
| 2026-10-15 | minor | PSD smart filters without options (Blur, Blur More, Average, Despeckle, Find Edges, Facet, Fragment, Sharpen, Sharpen More, Sharpen Edges, Solarize) map both ways as Photoshop stores them: hasoptions false, no Fltr, the four-char filterID (FILE-215-2) |
| 2026-10-15 | minor | PSD smart filters: Surface Blur (filterID 1135, surfaceBlur), Smart Blur (SmrB) and Radial Blur (RdlB) open as editable filters and save with the keys, types and enums measured in Photoshop; out-of-range, unknown-enum or extra-key entries (an off-centre Radial Blur) stay verbatim (#6298, FILE-215-2) |
| 2026-10-15 | minor | PSD smart filters: Smart Sharpen (filterID 1131, Gaussian removal; Lens/Motion Blur and legacy entries stay verbatim) and Dust & Scratches (DstS) open as editable filters and save in Photoshop's measured shape (#6300) |
| 2026-10-15 | minor | PSD smart filters: Diffuse (Dfs , DfsM mode), Trace Contour (TrcC, level and CntE edge), Crystallize (Crst) and Pointillize (Pntl, background from BckC) open as editable smart filters and save in the shape measured in Photoshop (#6302, FILE-215-2) |
| 2026-10-15 | minor | PSD smart filters: Wind (Wnd , WndM method, Drct direction), Extrude (Extr, ExtT type, size, depth, ExtR depth mode, solid front faces, mask incomplete blocks) and Tiles (Tls , count, offset, FlCl fill with the entry's FrgC/BckC) open as editable smart filters and save in the shape measured in Photoshop (#6314, FILE-215-2) |
| 2026-10-15 | minor | PSD smart filters: Offset (Ofst: Hrzn/Vrtc long, Fl FlMd Wrap/Background/Repeat) and Custom (Cstm: Scl , Ofst long, 25-long Mtrx) map both ways in filterFX, matching descriptors measured in Photoshop (FILE-215-2, #6304) |
| 2026-10-15 | minor | PSD smart filters: Mezzotint (Mztn, MztT enum, all 10 types) and Color Halftone (ClrH, Rds /Ang1–Ang4 longs) open as editable filters and save in Photoshop's shape, measured in Photoshop (FILE-215-2); Mezzotint's PhotoCraft-only seed is not saved |
| 2026-10-15 | minor | PNG: a stereo PNG's sTER pairing (PNG Extensions 1.4.0 §3.6) is read on open and written back on save, so the file still says it is a stereo pair (#6063) |
| 2026-10-15 | minor | Indexed Color documents save as 8-bit palette BMPs with their colour table instead of 24-bit RGB; a palette BMP opens with its declared number of colours, not 256 |
| 2026-10-15 | minor | PSD guides: image resource 1092 (guides v2) gives guides their own colours on import; 1092 and 1097 (guide GUIDs) are written back only while they still describe the document's guides, so an edit no longer leaves Photoshop a stale second guide list (#5966) |
| 2026-10-14 | minor | PSD smart objects warped with Transform Warp's Cylinder (warpCylinder, seven warpValues) are read and written: Replace Contents, Relink and Edit Contents re-render them wrapped instead of flat, and a regenerated SoLd no longer drops the warp (#4112). Vertical cylinders and ones with perspective are still unread |
| 2026-10-15 | minor | Bevel & Emboss Gloss Contour › Anti-aliased (antialiasGloss) is read and written, set by glossAntiAlias and shown in the Layer Style dialog; a PSD whose bevel is edited no longer loses it. Rendering still ignores contour anti-aliasing, as for the other effects' contours |
| 2026-10-15 | minor | Stroke › Overprint (overprint) is read and written, set by the stroke command's overprint and shown in the Layer Style dialog; an edited stroke no longer drops it. Rendering ignores it for now |
| 2026-10-14 | minor | Nikon NEF: the D4 profile's saturation level follows the sample depth (15520 at 14 bits, 3880 at 12), so 12-bit D4 files open as bright as their 14-bit twins instead of 2.6 stops darker (#5978) |
| 2026-10-14 | minor | Animated WebP: New Video Layer from File, Replace Footage, Reload Frame and Video Frames to Layers take every frame, composited, with the timeline rate from the durations (#1198) |
| 2026-10-14 | minor | PSD smart filter masks: Photoshop stores a smart object's filtered pixels without its filter mask and mixes the unfiltered ones (FEid) back in; import now mixes them and export writes them that way, so sf-filter-mask-hard, -gradient and sf-stack-blend-and-mask pass; Photoshop-oracle floor 185 → 188 of 258 |
| 2026-10-13 | minor | Lossy DNG (compression 34892) decodes: 8-bit baseline JPEG tiles and strips, CFA and LinearRaw, partial edge tiles; the stored values take the normal levels and LinearizationTable (FILE-215-11, lossy DNG part) |
| 2026-10-14 | minor | Corpus floors raised to the measured results of the CMYK, Lab, 32-bit, Levels, Threshold, Posterize, feather and pass-through fixes landed together: Photoshop-authored 165 → 185 of 258, io 146 → 148 of 170, psd-tools 242 → 249 of 309 |
| 2026-10-13 | minor | Large-file fixtures generated at test time (20 MP layered, 150-layer layout, 2.02 GB PSD, 4.38 GB PSB), opened, saved and re-opened by io tests/it/large_files.rs; FILE-216-2 done; P20/P63 open times measurable (#5107) |
| 2026-10-13 | minor | PSD smart filters: Pinch, Polar Coordinates, Ripple, Spherize, Twirl, Wave, ZigZag and Invert open as editable filters and are saved instead of dropped (checked against a Photoshop 27 file); a scaled Wave, a Wave with more than 64 generators and Shear stay verbatim |
| 2026-10-13 | minor | CMYK Hue/Saturation (not Colorize) and Color Balance work on C, M and Y as inverted RGB with black kept, on the inks for display, export and destructive edits; cmyk8/16 hue-saturation 100% → 0.4–0.7% bad pixels, color-balance 74% → 25% |
| 2026-10-13 | minor | CMYK Posterize works on the stored values (1 − ink), as Photoshop does: psd-tools posterize_cmyk passes (13.8 % → 0 of pixels off on the ink path); psd-tools floor → 242 of 309 |
| 2026-10-13 | minor | CMYK documents whose layers are plain raster layers plus Invert, Posterize, Threshold, Brightness/Contrast, Levels or Curves layers composite on their own inks for display, export and flattening: the cmyk8/16 oracles for those seven adjustments pass; Photoshop-oracle floor 151 → 165 of 258 |
| 2026-10-13 | minor | CMYK Threshold compares the Rec. 601 luma of the inks' plain complement, as Photoshop does (every pixel of cmyk8/16 threshold-128.psd); oracle bad pixels 1.6% → 0.2% |
| 2026-10-13 | minor | CMYK Brightness/Contrast (modern and legacy) curves each ink's stored value (1 − ink), exact on destructive edits; cmyk8/16 oracle bad pixels 71% → 48–57% (the RGB composite's separation still differs) |
| 2026-10-13 | minor | Modern Brightness/Contrast: the brightness curve refit to Photoshop, so the rgb and gray 8/16/32 brightness-contrast oracles pass; Photoshop-oracle floor 145 → 151 of 258 |
| 2026-10-13 | minor | Lab documents of plain layers with Invert, Posterize, Threshold, Brightness/Contrast or Lab Levels/Curves adjustment layers composite on the stored L, a, b instead of clipped display RGB, and flattening keeps them: lab16 invert, posterize-4, levels, curves and legacy Brightness/Contrast and lab8 invert and posterize-4 pass; Photoshop-oracle floor 145 → 152 of 258 |
| 2026-10-13 | minor | Levels round the gamma and output steps to whole levels too (8-bit), and the gamma above 1 starts along a toe of slope 2^gamma that joins the power curve: psd-tools levels_rgb and rgb8 stack-levels-curves-hue-posterize pass, rgb8/gray8 levels.psd exact; Photoshop-oracle floor 145 → 146 of 258, psd-tools 236 → 238 of 309 |
| 2026-10-13 | minor | 32-bit documents: legacy Brightness/Contrast, Channel Mixer, Photo Filter and the Black & White tint keep values above 1 and below 0 as Photoshop does (rgb32/gray32 brightness-contrast-legacy, rgb32 channel-mixer and black-white-tint pass); Photoshop-oracle floor 145 → 149 of 258 |
| 2026-10-13 | minor | Mask feathers blur with exactly the feather's variance (three extended boxes; whole-pixel boxes rounded 6 px to 6.48): psd-tools mask-parameters-no-real-channel passes, layer_mask_data 27 % → 4 % off; psd-tools floor → 240 of 309 (main 239) |
| 2026-10-13 | minor | Threshold splits on the luminosity 0.30 R + 0.59 G + 0.11 B of whole samples, as Photoshop does (8-bit: rounded to a level, halves down; 16-bit: against the level in 16 bits), not the Rec. 601 grey: psd-tools threshold_rgb and threshold_16bits_rgb pass; psd-tools floor → 241 of 309 (main 239) |
| 2026-10-13 | minor | A pass-through group that is the base of a clipping group and holds an adjustment layer renders isolated, as Photoshop does (its blend modes still reach the backdrop): psd-tools passthrough_clipping_mask_adjustment passes (was 50 % of pixels off); psd-tools floor → 240 of 309 (main 239) |
| 2026-10-13 | minor | 16-bit Posterize bins the 16-bit sample and lands on 8-bit levels through a 16-bit step, as Photoshop does (RGB, Grayscale and the CMYK/Lab channel path): psd-tools posterize_16bits_rgb and posterize_16bits_grayscale pass; psd-tools floor → 241 of 309 (main 239) |
| 2026-10-13 | minor | Gradient Map adjustment layers are driven by the W3C luminosity (0.3, 0.59, 0.11), not the Rec. 601 grey: rgb8 and rgb16 gradient-map.psd pass; Photoshop-oracle floor 145 → 147 of 258 |
| 2026-10-13 | minor | PSD: a "Saving Merged Transparency" global block (Mtrn, Mt16, Mt32; Photoshop's 32-bit documents keep a positive layer count) marks the merged image's first extra channel as its transparency: opening such a file no longer adds a "Transparency" alpha channel, and the oracle compares psd-tools transparentbg.psd's alpha (83.7 % → 0.9 % of pixels off; its shape edges remain) |
