 ## Revision history
 
 | date | change |
 |:--|:--|
+| 2026-10-13 | Photos: continuous-tone images are smoothed within their tones before quantising, and stacked layers go by lightness |
 | 2026-10-13 | The palette: made of the picture's own colours, noise-made colours merged, blend pixels settled, cuts where colours differ most, colours compared in Oklab |
 | 2026-10-13 | Sub-pixel edges and the outline fitter in Black and White, Grayscale and Color; the harness gains an aliased variant and an "outside px" column, so the baseline was measured again with it (same tracer, main at `baf9693f`) |
 | 2026-10-12 | The harness and the baseline: every preset measured before any change to the tracer |

 - **Interface languages, vertical type:** Preferences ▸ User Interface (or VectorCraft ▸ Language on macOS) picks Automatic (the system locale) or a registered language, persisted as `interfaceLanguage`. Translations come from per-language catalogs (`i18n/*.tsv`): Traditional and Simplified Chinese, Japanese, German (every `de-*` locale), Spanish (neutral international Spanish, for every `es-*` locale), French (every `fr-*` locale), Italian (every `it-*` locale) Russian (every `ru-*` locale) and Ukrainian (every `uk-*` locale) cover the whole interface, Czech and Brazilian Portuguese every menu label, Brazilian Portuguese the shell's `tl!` literals too (tested); German, Spanish, French, Italian, Japanese, Russian and Ukrainian also translate status-bar and error messages as they are shown (`@msg` templates, every message literal tested; the messages themselves stay English for agents); untranslated text stays English. Japanese and Chinese glyphs come from the craft-fonts build input (release builds) or the installed fonts, Czech, German, Spanish, French, Italian, Russian and Ukrainian ones from the bundled UI fonts. The web app follows the browser's languages (or `?lang=`). The Basic toolbar's Type button holds Vertical Type in its flyout. Vertical Type, Vertical Area Type and Vertical Type on a Path create vertical text (columns right to left, upright CJK glyphs and marks with `vert` alternates, Latin and longer numbers on their side, two- and three-digit numbers set as tate-chu-yoko in one em of the column (kept whole when justified), upright glyphs centred on the column (tracked or justified too), point type's anchor on the first column's centre line); kinsoku applies to horizontal and vertical Japanese (Paragraph panel › Kinsoku Set, `text.setFormat {kinsoku}`: Hard, the default, keeps closing marks, iteration marks, the prolonged sound mark and small kana off the line start and opening brackets off its end; Soft lets 々, ー and small kana start a line as JLREQ's level 3 rules do; None turns it off), and justified Japanese lines spread their room between characters (not inside Latin words); Paragraph panel › Mojikumi Set (shown with Preferences › Type › Show East Asian Options, `text.setFormat {mojikumi}`): None or Line-end Punctuation Half Width (new type's default, as in Illustrator; older documents and imported text keep None) shares one half-em space between consecutive punctuation, sets a closing mark ending a line half width and an opening bracket starting a line flush with its start (a paragraph's first line at its first-line indent, JIS X 4051's principle in JLREQ 3.1.5), and puts a quarter em between Japanese and Latin letters or digits; Paragraph panel menu › Top-to-Top / Bottom-to-Bottom Leading measures leading from em box top to top (area type's first line touches the frame) or from baseline to baseline (new type in a Japanese interface starts top to top, with em box centre character alignment, #432); Paragraph panel menu › Burasagari None / Regular / Force (`text.setFormat {burasagari: "none"|"standard"|"forced"}`) hangs an East Asian comma or full stop (、。，．､｡) ending an area type line outside it, Regular (new type's default) when it doesn't fit and Force always (the rest of the line then fills the measure; closing brackets and Latin punctuation don't hang); Character panel menu › Character Alignment (with the East Asian options; `text.setFormat` or `text.setRangeStyle {charAlign}`) lines characters smaller than the largest on their line up on the Roman baseline, the em box top/right, centre or bottom/left, or the ICF (ideographic character face) top/right or bottom/left, from the font's BASE table or, without one, the average ink box of some ideographs and kana; Proportional Metrics (the same menu; `{proportionalMetrics}`) sets full-width glyphs on the font's proportional widths (OpenType `palt`) in horizontal type and upright glyphs on its proportional heights (`vpal`, shaped top to bottom; fonts without vertical metrics keep their cells) in vertical type, and Line-end Punctuation Half Width takes nothing more off the punctuation they re-spaced; Type ▸ Type Orientation switches existing text; caret, selection, hit testing and arrow keys follow the writing direction. Vertical text exports to PDF as real text and to SVG as outlines.
 - **Transparency:** opacity masks (clip/invert/disable/link), exported as SVG `<mask>` and PDF soft masks. The constant alpha soft mask that PDF and `.ai` export draw a CMYK page with transparency through is white, so applications that read every soft mask by its luminosity show the page too (#1359, part of #1286).
   Disable, Enable, Unlink and Link Opacity Mask and Opacity Mask Options (`transparency.setOpacityMask`) record no undo step when every mask they act on already has the flags they set.
-- **Image Trace, measured:** `crates/trace/tests/quality` traces drawings made from known vector art with every preset and [`image-trace-quality.md`](image-trace-quality.md) records the numbers against the baseline. Black and White, Grayscale and Color place each edge by the blend of the pixels across it (to a fraction of a pixel on anti-aliased and blurred images; hard-edged images are read as staircases) and fit outlines as Flat Logo does. *Measured* on each preset's own inputs, all sizes and variants: Default's outlines went from 0.31 px off on average to 0.09 (largest 1.51 to 1.02), Black and White Logo's from 0.27 to 0.06 with 0.3 kinks per trace where it had 15, and the gaps between abutting paths from 64 px to 22. On clean curved shapes Black and White Logo is 0.02 px off (the open tracer measured beside it: 0.20). Still weak, by the same numbers: 6 and 16 Colors shatter noisy flat art, High Fidelity Photo makes 51,000 paths of a 1 megapixel photo-like image, thin lines in blurred images take 7 times the art's anchors.

On clean curved shapes Black and White Logo is 0.02 px off (the open tracer measured beside it: 0.20). The palette is made of the picture's own colours (blends along edges take none of it, colours that noise made of one colour merge, a blend pixel goes to one of the two colours it lies between; #1504): 16 Colors on flat art, all variants, went from 70 paths to 4.2 and from 5.1 px off to 0.13, with no path left in a colour the art doesn't have (5.9 before). Photos are smoothed within their tones before they are quantised and stacked layers go by lightness (#1516): High Fidelity Photo went from 3,653 paths to 121 with its colour error down from 2.30 to 1.75, and a 16 megapixel photo-like image is traced in 3.5 s where 4 megapixels were refused. Still weak, by the same numbers: abutting paths leave 22 to 50 px of gaps (each region's edge is still fitted on its own), thin lines in blurred and scanned images take several times the art's anchors, hairlines under half a pixel are lost to the threshold, a scan's uneven paper splits into tones when more colours are asked for than the art has, and a 16 megapixel photo takes about 4 GB while it is traced.
 - **Image Trace Flat Logo mode:** a fourth mode beside Black and White, Grayscale and Color, for flat-colour logos. Each pixel is read as a blend of the logo's colours (found automatically or named), the blend is interpolated smoothly and every outline is placed where two colours are equally present, so edges are accurate to a fraction of a pixel. Outlines are then cleaned: corners the blur rounded are put back, near-straight runs and near-circular arcs become exact lines and arcs, the rest is fitted with as few Béziers as the tolerance allows, touching colours overlap by a hair so no gap opens, and an outline that strays from the raw contour is fitted plainly instead. Gradients and photos are refused with advice to use Color. *Measured* (a local experiment, not run in CI): a flat-colour logo's vector original was rendered down to a soft 199 × 100 px transparent PNG, traced, and the result compared with the original at 1600 px wide. The built-in colour presets (6 Colors, 16 Colors, High Fidelity Photo, Low Fidelity Photo) had a mean edge error of 2.5 to 3.4 px and region overlap of 0.88 to 0.91; Flat Logo had 0.78 px and 0.966 (0.48 px and 0.975 from a crisp source), in about 0.1 s. Limits: flat-colour art only; needle-thin sharp tips are shortened by about 1.7 source pixels because the blur erases them; it works at no more than 1024 px on the long side (larger images are averaged down first); only one logo family has been scored against a vector original.
 - **Advanced art:** live Blends (steps/distance/smooth colour, editable spine, anchor-targeted Blend tool, faithful interpolation, knockout), Envelope Distort (warp/mesh/top object, Reset, full Envelope Options, mesh handles, Edit Contents; type, images, symbols, gradients, patterns and appearance distorted everywhere), Liquify tools with options and pen pressure, Puppet Warp with rotating pins, Perspective Grid with presets, movable planes and projected type (choosing a perspective tool shows the grid; Hide Grid hides it with the tool still chosen), Gradient Mesh, Shape Builder (stroke-only open paths and lines cut the regions they cross and enclose regions of their own, and regions they bound merge without seams where the lines cross at rounded coordinates (#893); filled open paths count as closed; erase mode while Alt/Option is held: a minus pointer, red highlights of what will go, a click or drag deletes the regions touched, the pieces of open lines and the edges (outline pieces between the points where paths meet, opening their paths there) it passes over, one undo step, `shapeBuilder.merge {erase}` and `shapeBuilder.regions` edges over MCP), Live Paint (every path an edge, open lines included), Image Trace (12 presets, colour layers traced in parallel; a trace past two million anchor points is refused with advice rather than running out of memory, an image over 64 megapixels is traced scaled down to that size (aspect kept, paths at the image's own size) and one over 192 megapixels is refused, and a selection too large to outline shows its bounds (#525); Object › Image Trace › Make and Make and Expand trace at once with the Default preset, #543; with an image selected the Control bar and the Properties panel show Image Trace, whose arrow traces with any preset, Mask (`object.maskImage`: a clipping path on the image's outline, selected so its handles crop), Crop Image (a crop box on the image, starting on its part over the artboard, dragged by its handles or inside it, the outside dimmed, with X/Y/W/H, Apply and Cancel in the Control bar, Enter and Escape, #734; `object.cropImage {rect}` for agents, `{trim: true}` cuts an image to its pixels that aren't fully transparent, pixel for pixel) and Embed or Unembed in place of Fill and Stroke; with an Image Trace object selected, its Preset (choosing another traces again), View, the Image Trace panel and Expand, plus Release in Properties; the five View modes (Tracing Result, with Outlines, Outlines, Outlines with Source Image, Source Image) redraw a trace on screen without tracing again, are saved with it and `imageTrace.setView` sets them, while exports and Expand keep the result; the panel's Advanced section is a header that stays open or closed as it was left (part of #641); Color mode's Palette: Limited, Full Tone (as many colours as the tones need, Less … More), Automatic (flat art with its own colours, else Full Tone; a heuristic) and Document Library (the most used colours of the document's swatches or a swatch library, filled with the swatch colours as they are), part of #641; Advanced › Create: Fills and/or Strokes, where lines up to the Stroke width trace as stroked centre lines (distance transform, thinning, a skeleton graph with spurs pruned, curve fitting; one width per line; without Fills, wider areas become stroked outlines), part of #641), pattern swatches with pattern editing mode, live Repeat (radial/grid/mirror).
