andeecollardandClaude Opus 5.5 1e06c82800 Image Trace: Auto Color keeps rare but distinct colours

The Automatic palette counts flat art's colours by area (a colour needs
about 1% of the picture, 0.5% at Colors 100) and fits that count with
median cut and area-weighted k-means. A stem, a highlight, or a near
white beside a pale background (within 24 levels, so in one box) was
averaged into a large neighbour; mixed-colour merging and Noise could
then remove what was left.

On the flat route only, after the count is fitted, rare_colours finds
the colours too rare or too close for it and keeps those that are
distinct (at least 2.5 in Oklab x 100 from every palette colour and from
the main colour each stands for), flat (mostly one histogram bin) and
drawn (a 4-connected region of their own unblended pixels of at least 8
pixels, or three of at least 4); a colour lying between two others, as
anti-aliasing mixes them, must also have an inside. At most six, largest
region first. They stay fixed while the other colours are refitted
around them; merge_mixed leaves them alone; denoise_keeping keeps their
regions of 4 pixels or more whatever Noise is (smaller specks still go).
Full Tone, Limited and Automatic's continuous-tone route are unchanged,
and denoise without kept labels is as before.

Methods cited in the code: median cut (Heckbert 1982), k-means (Lloyd
1982), Oklab (Ottosson 2020), salient-colour preservation (Fukuda et al.
2019, doi:10.1117/12.2521607). The rule and its numbers are VectorCraft's
own; Adobe does not document how its palettes are chosen.

Tests (code-drawn): a rare stem or patch over 2-8 flat colours, hard
and anti-aliased at 1x and 2x; near-white highlights on #FFF4E0 kept and
still paths at Noise 16; a 3 px #909090 stem on #808080; scattered
single pixels of the same areas add no colour; denoise_keeping at Noise
0-32.

Measured on 66 synthetic flat logos (22 designs x hard 1x, anti-aliased
1x and 2x; local inputs): every key colour and no spurious one in 66
(was 39); missing key colours 0 (was 43), spurious 0 (was 2), merged
pairs 0 (was 46); rendered dE00 0.348 -> 0.138. Four public-domain scan
crops take the continuous-tone route and are unchanged.

Auto Color keeps rare colours

The Automatic palette (Auto Color) counts flat art's colours by area: a colour needs about 1% of the picture (0.5% at Colors 100) to be counted, and the count is then fitted by median cut (Heckbert 1982) and k-means (Lloyd 1982), weighted by area. A stem, a highlight or a cream close to a pale background was averaged into a large neighbour, and Noise could remove what was left of it. Now, on the flat route only, after the count is fitted, the colours too rare or too close for it are found and kept when they are:

distinct: at least 2.5 (Oklab × 100; Ottosson 2020) from every palette colour and from the main colour each one stands for;
flat: mostly one histogram bin;
drawn: a 4-connected region of their own (not blended) pixels of at least 8 pixels, or three of at least 4 (repeated highlights); a colour lying between two others, as an edge's anti-aliasing mixes them, must also have an inside (pixels whose four neighbours are all of it).

At most six are kept, largest region first. They are fixed while the other colours are refitted around them, mixed-colour merging leaves them alone, and Noise removal keeps their regions of 4 pixels or more (smaller specks of them still go). This follows the idea of salient-colour preservation in palette reduction (Fukuda et al. 2019, doi:10.1117/12.2521607); the rule and its numbers are VectorCraft's own. Full Tone, Limited and the continuous-tone route of Automatic are unchanged.

Tests (code-drawn): automatic_keeps_a_rare_distinct_stem_or_patch (2, 3, 5 and 8 flat colours and a contrasting stem 1–4 px wide or a patch, about 0.05% to 0.5% of the picture, hard and anti-aliased at 1× and 2×: the stem's colour is kept and no other is added), automatic_keeps_near_white_highlights_on_a_pale_background (ten white islands of about 12 px on #FFF4E0: kept, each still a path at Noise 16), automatic_keeps_a_thin_low_contrast_stem (#909090 on #808080, 3 px), scattered_noise_adds_no_colour (the negative control: the same areas as single scattered pixels add no colour) and noise_keeps_a_kept_rare_colours_regions_but_not_its_specks (Noise 0 to 32).

Measured on 22 synthetic flat-colour logos drawn from known palettes, each hard 1×, anti-aliased 1× and 2× (66 inputs, used locally and not committed; a key colour is missing when no traced colour is within ΔE00 5): every key colour and no spurious one in 66 of 66 (was 39); missing key colours 0 (was 43), spurious 0 (was 2), key colours sharing one traced colour 0 pairs (was 46); mean rendered ΔE00 against the input 0.138 (was 0.348); paths 2547 → 2586, anchors 27,204 → 24,896, trace time 2.85 → 3.02 s in all. On four public-domain scan crops (1024 × 1024) Auto Color takes the continuous-tone route and nothing changes: 14, 72, 199 and 98 colours, the same paths, anchors and rendered error (2.11, 5.66, 9.15 and 1.00 ΔE00), time within run-to-run spread.

Large images

Images over 1500 px on a side are traced with a warning that they trace more slowly (see image-trace-adjustments.md), and the anchor limit that guards memory is 8,000,000 (2,000,000 on the web) instead of 2,000,000. Measured through imageTrace.make (release build, 4 cores, one trace at a time; memory is the peak allocated above the placed image, and what the document keeps after the trace) on code-drawn photo-like pictures (40 soft-edged shaded discs on a gradient, texture, sensor noise):

(The last two rows were measured without a limit; they are refused now.) The 4000 × 3000 High Fidelity
Photo trace was 86,000 anchors under the old limit; a noisier scan of the same size would have been
refused. At 8,000,000 anchors a trace keeps about 0.7 GB, with a peak of about 0.9 GB while tracing.

Collapsed loops keep few segments

A small closed loop (or a piece that returns to its own junction) whose fit collapsed to a single cubic cannot stay as one, so it kept every positioned point as a straight segment. A looser Paths collapses more loops, so it could give more segments than a tighter one. Such a loop now tries the fewest segments that still hold it, each only if the result keeps an area (more than 0.25 px²) and stays within 1.5 × max(tolerance, 0.5 px) of the points both ways: the fit at up to three somewhat tighter tolerances (what a slightly higher Paths gives); for a closed loop then two cubics split at its start and its farthest point, then the outline simplified at the tolerance and finer; the positioned points last, as before. Test on code-drawn images: a_higher_paths_never_gives_fewer_segments (32 seeded 48 px images of soft blobs in four colours plus pixel noise, Color and Black and White, Noise 1 and 3, segments at Paths 0, 25, 50, 75 and 100 must not fall). Before, six runs fell, e.g. 125 → 79 segments from Paths 0 to 25 (seed 21, Color, Noise 1) and 71 → 63 → 52 from Paths 0 to 50 (seed 3, Black and White, Noise 3); now they are 75 → 79 and 41 → 48 → 52. One image (seed 16 in Black and White) still falls from 140 to 136 segments between Paths 0 and 25, before and after this change; that fall has another cause, still open, and the image is left out of the test. The crate's other tests pass unchanged.

Notches read only their own piece

Where the pixel at a sharp corner falls to the other colour, the outline cuts the corner in two one-pixel steps, and between two straight edges of three cracks or more those two steps become one point, where the two edges meet (a notch). Whether the edges were long enough was measured on the whole loop. An edge can run on past a junction in one region's loop while the region across it, whose loop turns at that junction, sees a shorter edge: one side made the notch and the other did not, the shared piece got different points on each side, and the abutting curves left a gap. The rule in subpixel::outline now also requires the three cracks of each edge next to the notch to lie in the piece (no junction among them), as the corner-pixel correction above it already did. Test on code-drawn images: noisy_colour_images_leave_no_sample_uncovered (20 seeded 36 px images of soft overlapping blobs in four colours plus pixel noise; Color, 5 colours, Noise 1 and 2, Paths 0, 50 and 100; five sample points per pixel must each lie in some path). Without the condition 93 sample points were uncovered (seeds 9, 11 and 13); with it none are. The crate's other tests pass

Same sub-pixel shift from either side of an edge

Each crack between two regions is moved by a sub-pixel shift read from the image. The reading looked for a thin run (one to three pixels) on the crack's inside before one on its outside, so where both sides were thin (a one- or two-pixel sliver beside another, as in soft gradients and noisy scans) the two regions of the crack got different shifts, their shared piece different points, and the abutting curves left slivers that no path covers. Layers::shift now averages the reading from either side, (s(c) - s(c flipped)) / 2, which is exactly antisymmetric in floating point, so both regions get the same points. Tests on code-drawn images: a_crack_between_thin_slivers_has_the_same_shift_from_either_side (a noisy ripple of 1–2 px columns at three thresholds: every crack's shift is the exact negative of its flipped crack's, and the image does have cracks the one-sided reading gets wrong) and, in tests/shared_boundaries.rs, thin_slivers_on_both_sides_of_an_edge_leave_nothing_uncovered (a 48 px noisy ripple in Black and White at thresholds 140, 157, 170 and Paths 0, 50, 100, sampled on the 4 × 4 grid per pixel the shared-boundary check uses). With the one-sided reading 482–1,228 sample points per trace were uncovered; now none are. The crate's other tests pass unchanged.

A simpler contour walk

contour::trace_mask follows each region's outline along the pixel cracks with the inside on the right. It used to build a table of outgoing directions for every pixel corner in a raster pass and then follow it. It now works out each turn during the walk from the two pixels ahead of the current corner (right if the one ahead on the right is outside, straight if the one ahead on the left is, else left; so at a saddle it turns right and diagonal pixels stay apart, as before). Loop starts are found by scanning the pixels for a top edge on the outline, with one flag per pixel for a top edge already walked. A mask of the wrong length now gives no loops instead of failing an assertion. The output is identical: the_walk_equals_the_stored_direction_walk compares it with a test-only copy of the previous walk on all 65,536 masks of 4 × 4 pixels and on 400 seeded 23 × 17 masks. Time (best of 7, release build, 4 cores): the walk alone on 2000 × 2000 masks 19.1 ms vs 26.6 ms (a smooth pattern), 81.3 vs 93.2 ms (12% random pixels), 223.1 vs 238.1 ms (50% random pixels); whole traces of 1000 × 1000 images 73.1 vs 77.1 ms (Black and White), 249.6 vs 251.7 ms (Color, 6 colours) and 214.1 vs 218.6 ms (Color, 6 colours, Noise 1), with the same segment counts.

Noise threshold stability (local development, 2026-10-14)

Noise must merge whole 4-connected regions, including pixels absorbed by an earlier merge. A count of regions alone cannot establish this: one old region may split while others disappear. The repeated-pass implementation at a0671777 fails a partition regression at case 0, Noise 3.

The replacement discovers the initial regions, processes them in deterministic increasing-area order, and keeps their membership current. All adjacent regions of the chosen colour join the merge, with ties resolved by label and region id. Increasing Noise continues the same merge sequence: every lower-threshold region remains wholly inside one higher-threshold region. Regions exactly at the threshold stay; an opaque island surrounded by transparency stays; transparent pixels are never recoloured. A merged region is tested at its current area, so a 1-pixel speck joining a 2-pixel region meets Noise 3 and is retained as one 3-pixel region.

Tests generate 64 multicolour 7 × 7 grids with transparent barriers and check every threshold from 0 through 24 with an independent component traversal. They assert nested partitions, non-increasing region counts and unchanged transparency. Separate cases check the strict threshold, isolated opaque islands and invalid or overflowing grid dimensions. The existing no-small-region and traced-path regressions remain active.

This uses region and heap bookkeeping instead of repeated full-image passes, so memory and photo quality must also be checked. Local photo/scan validation uses fixed hashed inputs and identical settings on unchanged current source and the candidate, including separate portrait crops and white-composited PNG comparisons. These local fixtures are not repository assets. The parity score is unchanged.

Pieces returning to a junction

An outline piece can return to its starting junction while being fitted as an open chain. At loose Corners/Paths settings, a nonzero positioned boundary could collapse to one cubic and lose a small corner-touching mark. Fixed-end pieces with identical endpoints and fewer than two fitted segments now retain their positioned boundary when its area is finite and nonzero. Fitting the shared piece this way also gives an abutting fill exactly the reversed boundary, including within a compound path. Six source-generated regressions check 1- and 2-pixel regions through four rotations, both windings and large translations; fixed junctions; zero positioned area; free ends; Noise controls; and shared edges through four rotations and black/white inversion. Noise 2 still removes the 1-pixel mark. The white-hole Noise check is a control, not a reproduced returning-hole case. Defaults are unchanged; these tests establish survival and edge consistency, not a new artistic-quality or parity score. This is separate from the closed-contour recovery in #2012 and straightening guard in #2025.

Thin closed outlines with Snap Curves To Lines

A four-pixel stair-step mark can fit as two straight cubics along the same diagonal, leaving a closed path with zero area. The outline-distance checks accept this because both sides are close to the chord. Closed fitting now checks analytic curve area after straightening and upright levelling; if a nondegenerate source loop has lost its interior, it retains the positioned boundary as an unsimplified polygon. The area integral is translated to a local origin to reduce cancellation. This numerical degeneracy check is not a new Noise or minimum-feature-area setting.

fit::snap_area_tests covers the mark at two positions and five Corners settings, a white stair-step hole, reversed/rotated closed boundaries with exactly matching opposite curves, and a narrow filled rectangle. Noise still removes the four-pixel mark or hole when set to 5. It does not change open-piece fitting, global Snap tolerances or defaults, and it does not address every possible zero-area compound outline. The preset quality table below is the previous measurement, not a rerun of that full report.

Tiny closed contours

A coarse fit can reduce a small closed outline to one cubic, which the editable-path builder cannot represent as a closed subpath with two anchors. Previously that dropped the component or hole after it survived Noise. The fitter now retains the positioned contour without further simplification when that minimum is not met. Corners and Noise defaults are unchanged. Three source-generated regressions cover a one-pixel island, a one-pixel hole with opposite winding, and a stepped seven-pixel region across Corners values. They also check that Noise still removes the island and fills the hole when its threshold requests that. These are survival and winding checks, not a new quality-harness baseline or a general claim about small-feature fidelity.

How it is measured

crates/trace/tests/quality draws its own inputs from vector art (no image files), traces each with every built-in preset, and measures the result:

TRACE_QUALITY_REPORT=report.md cargo test --release -p vectorcraft-trace --test quality -- --ignored

Inputs (drawn anti-aliased at 128, 256 and 512 px, and at 256 px also blurred, with compression-like noise, as a scan of ink on cream paper with uneven light and grain, and aliased: one hard sample per pixel, no anti-aliasing):

kind	inputs
2026-10-15	Fixed-end pieces returning to their junction retain their positioned nonzero boundary when fitted to fewer than two cubics; source-generated tests cover survival, winding, shared-edge equality, translations and Noise controls. Defaults and parity scores unchanged.
curved shapes	a circle; two ellipses; a rounded badge with a round hole; a letter D with its counter
polygons	a triangle, a turned square and a hexagon; a five-pointed star; a letter A with its counter
thin lines	five lines 0.5, 1, 2, 3 and 5 units wide (of a 256-unit square), a few degrees off the pixel grid

The letters are drawn by hand from lines and curves: the repository has no font to set them in.

Columns

column	meaning
ΔE	the trace drawn again against the source: mean colour difference in Oklab × 100 (black to white is 100)
edge ΔE	the same, weighted by how strong an edge the source has at each pixel
off mean, off max	distance (px) from the traced outlines to the art's true outlines: wobble and staircase
missed max	largest distance (px) from a true outline to the nearest traced one: what was lost
paths, anchors	counts, the background's frame aside
× art	anchors per anchor point of the art itself (1.00 is as economical as the original)
lines %	share of the outline length made of straight segments (100 is right for polygons, 0 for a circle)
upright %	share of the outline length that is exactly level or upright
corners %	share of the art's sharp corners with a traced corner within 1.5 px
kinks	anchors where the outline turns by 10° or more away from any true corner
odd colours, odd px	paths (and their area) in a colour the art doesn't have: slivers along anti-aliased edges
gap px, overlap px	area no path covers, and area covered twice (abutting traces with a white background only)
specks	paths under 6 px of area
centre off, width off, anchors a stroke	stroked centre lines (Create: Strokes) against the thin lines they trace: mean distance (px) from the true line's centre line, mean error (px) of the stroke width, anchors per stroked path
shapes %	with Shapes on, the share of the plain shapes that came out as that shape (a shape, not a path, whose outline lies within 0.6 px of the true one)
false shapes	with Shapes on, paths made a shape whose outline strays more than 0.6 px from the art (a shape the art does not have, or one put where it is not)
grouped %	with Auto Grouping on, the share of the paths that were put inside another (the picture is painted as the app groups it for every other measure of that row: each path together with those inside it, in the order they were traced in; a ΔE equal to the row without the option says grouping changed nothing that shows)
gradient paths	paths filled with a linear gradient (on inputs that are flat colour, every one would be a gradient that is not there)
found %, angle off, ramp off	on the linear-gradient inputs: the share of them in which a gradient was found; and for those found, the largest angle (degrees) between the true gradient line and the traced one, and the largest difference (levels of a channel, 0 to 255) between the true colours and the traced gradient's at 17 points along the true line
outside px	how far the trace reaches outside the image: a curve that strays

Rows named "…, enhanced" are that preset's enhanced version (Auto Grouping on; Shapes on in all but High Fidelity Photo) on the same inputs as the row of the preset itself. Flat Logo has no enhanced version.

Black-and-white presets trace black: on the scanned variant their ΔE includes the paper's and ink's own colours. Silhouettes has its threshold at 200, not 128: its outline lies where the image crosses that tone, about 0.3 px outside the true edge on anti-aliased art and 0.8 px on blurred art; with the threshold at 128 the same preset is 0.110 px off on its inputs (1.00 px at most), as the other black-and-white presets are. – means the measure does not apply; all that nothing was traced.

4. Yardstick

Inkscape 1.4.2's Trace Bitmap, run as a black box through its object-trace action (two scans, background removed, its other settings as they come) on the same one-colour drawings, and its SVG output measured by the same code. Compare with the black-and-white presets on the same kinds of input in section 2 and 3.

Centre lines

Measured 2026-10-17 with maximal-disc pruning and junction merging, against base 3e44478f. Earlier preset and cost tables retain their previous measurements. Regenerate only this class:

TRACE_QUALITY_CLASS=centre-lines TRACE_QUALITY_REPORT=centre-lines.md cargo test --release -p vectorcraft-trace --test quality quality_report -- --ignored --nocapture

Junction clusters use their deepest pixel and a disc radius of distance − 0.5 px. Terminal branches shorter than r + max(2, 0.5 × min(2r, Stroke)) are pruned, shortest first. Tiny self-loops inside the junction disc are removed; overlapping junctions and geometrically split crossings merge, and runs join through degree-two nodes. Simplification is bounded to 32 rounds; nodes and branches are each capped at 200,000. An over-budget blob stays with the fill path. Whole-blob selection, ink refinement, cap detection and curve fitting retain their current rules.

Code-drawn scenes only: 23 scenes, each anti-aliased (8×8 coverage samples) and hard (that coverage thresholded at 0.5). Coordinates, widths and scene Stroke values are fixed; junction/letter/crossing coordinates include the 0.27/0.41 px offset. Create Fills and Strokes are on, Stroke is the scene's limit (13 px, mix 6 px, varying 12 px), Black and White threshold 128, Noise 4, Ignore White on, other settings at their defaults. Today's tracer has no minimum-length setting (the dashed scenes specify 0 for future use).

Distances use dense exact centre samples (≤0.25 px), emitted curves sampled at ≤0.5 px control-polygon steps, and nearest-point searches capped at 30 px. Found is the fraction of true samples within 1.5 px; width errors use output samples within 2 px of a true stroke. Samples inside exact fills are excluded. Topology is recovered from emitted subpath endpoints and intersections, merging coincident positions within 0.05 px; an endpoint contributes one arm, an interior two. Junction matching radius is local true width + 3 px; ends use half-width + 4 px. Each match is used once. Free ends exclude true junctions, corners, other strokes and fills; unmatched emitted ends are spurs. Junctions/ends within 2 px of fills are excluded. End error is distance, with signed error along the outward tangent in parentheses. Coverage is a union of painted output at pixel centres (0.02 px flattening tolerance, actual emitted caps), compared with the exact swept shape at pixel centres, for both input variants. Area error is signed relative to exact area. Anchors counts stroke anchors, including all compound subpaths; paths counts stroked + filled paths. Time covers tracing only, one scene at a time. Profile-dependent columns are unavailable (–).

aa totals: junctions 44 correct, 1 wrong degree, 0 missed, 94 extra (of 45); ends 682 of 688; spurs 121.

hard totals: junctions 44 correct, 1 wrong degree, 0 missed, 22 extra (of 45); ends 681 of 688; spurs 171.

Scope of the improvement: correct junction degrees rise from 30/45 to 44/45 in each variant; missed junctions fall from two to zero. Extra junctions fall from 104 to 94 aa and 27 to 22 hard. Spur totals remain 121 aa / 171 hard: the one-pixel-line and circle scenes contribute 120 / 170 of those, with unchanged path counts (one-pixel lines: 93 aa / 92 hard; circles: 25 aa / 23 hard). The graph stage does not reconnect separate blobs. Raw graph tests cover straight lines at 24 angles, junctions and 20–90° crossings; these do not replace the emitted-path measurements above. The remaining spur/extra-junction target is not met by this graph-only change.

Revision history

date	change
2026-10-17	Auto Color keeps rare but distinct colours (stems, highlights, near-white on pale backgrounds): 66 of 66 flat test logos keep every key colour (was 39); scans unchanged
2026-10-17	Images over 1500 px on a side trace with a warning; the anchor limit is 8,000,000 (2,000,000 on the web); time and memory of 2000 × 2000 to 6000 × 4000 code-drawn photos
2026-10-17	`Raster::new` returns an error for RGBA bytes of the wrong length (it failed an assertion) and `Raster::pixel` reads nothing past the raster; traces of valid images unchanged
2026-10-17	M12: maximal-disc graph pruning, split-crossing merges and degree-two joins; correct junction degrees 30→44/45 aa and hard, none missed; remaining spurs unchanged. Centre-lines rerun, scores and earlier tables unchanged.
2026-10-17	M12: exact per-blob Euclidean distances and Guo–Hall thinning; centre-lines rerun on 46 inputs. Ends found: aa 638→682/688, hard 631→681/688. Whole-blob stroke/fill choice retained; preset/cost tables unchanged.
2026-10-17	M12: add the ignored centre-lines class and measure the existing Create Strokes output on 23 code-drawn scenes, aa and hard; centre/width/topology/end/coverage metrics, no new images, dependencies or behaviour
2026-10-16	Image Trace: a loop or junction-returning piece whose fit collapsed to one cubic keeps the fewest segments that hold its area and course instead of every positioned point, so a higher Paths no longer gives fewer segments on code-drawn noisy images (six falling runs to none; one other cause remains).
2026-10-16	Image Trace: a notch corner is cut only when the straight edges beside it lie in the shared piece, so both regions of the piece get the same points (code-drawn noisy colour images: 93 uncovered sample points to 0).
2026-10-16	Image Trace: a crack's sub-pixel shift is the mean of the readings from its two sides, exactly antisymmetric, so abutting regions get the same points on thin slivers (a code-drawn noisy ripple went from 482–1,228 uncovered sample points per trace to 0).
2026-10-16	Image Trace: the contour walk works out each turn from the pixels as it goes instead of following a precomputed table of per-corner directions; identical loops on all 65,536 4 × 4 masks and 400 seeded masks, and no slower (whole 1 MP traces 1–5% faster).
2026-10-14	Closed fitting retains the positioned boundary when straightening collapses a nonzero-area loop; four generated regressions; preset scores unchanged
2026-10-14	Tiny closed fits retain their positioned outlines instead of losing islands/holes; three generated regression tests; quality-harness baseline unchanged
2026-10-14	Gradients: a gradient that noise or a soft rim broke into pieces is found in its largest piece and grown over the rest (blurred and noisy linear gradients: 3 to 11 paths beside the gradient down to 0.5 with 6 Colors, 24 to 56 down to 0.5 to 1.5 with High Fidelity Photo)
2026-10-14	Enhanced versions of the presets (Auto Grouping, and Shapes in all but High Fidelity Photo; Flat Logo has none), each measured beside its preset; a hole that one colour fills is the same shape as what fills it, rectangles are sized by where their sides lie, and a group keeps its paths in the order they were traced in (grouped, a letter with a counter was painted with a light seam: Default with Auto Grouping, edge ΔE 10.24 to 9.88)
2026-10-14	Create: Strokes: a line whose ink is cut square at its ends gets square caps, and a wide line whose skeleton hooks towards a corner of its end ends on the line it was following (Outline: largest distance 2.94 px to 0.88; aliased lines 0.88 to 0.81)
2026-10-13	Shapes: corners that anti-aliasing or blur took a little off are corners, a rounded rectangle gets the radius that fits, a polygon its sides from the outline itself, hard-edged outlines a little more room (plain shapes found: 57 to 62% up to 98 to 100%); a "false shapes" column
2026-10-13	Flat Logo: the tones a scan's uneven paper makes of one colour are one colour (scans: 470 paths and 21 px off to 8.5 paths and 0.09 px)
2026-10-13	Snap Curves To Lines moves no end of a line by more than 1.6 px: long lines a degree or two off stay as the image has them (Technical Drawing: largest distance 4.21 px to 1.46)
2026-10-13	Gradients (off unless asked for): areas that are a linear gradient are found before the palette is made and traced as one path with a gradient fill; linear-gradient inputs with known lines and stops, and four columns for them
2026-10-13	Auto Grouping (off unless asked for): each path that has others inside it is grouped with them; a "grouped %" column, and three presets measured with the option on
2026-10-13	Shapes (off unless asked for): filled outlines that are a circle, an ellipse, a rectangle or a regular polygon come out as that shape; corners whose pixel is mostly outside the shape are corners; plain-shape inputs and a "shapes %" column
2026-10-13	Create: Strokes: centre lines placed in the middle of their ink and as wide as it, fitted as outlines are; centre-line distance, width error and anchors per stroke measured against the thin lines' truth
2026-10-13	Snap Curves To Lines levels lines within 2.5 degrees of level or upright; askew inputs and an "upright %" column, so the baseline was measured again with them (the tracer of main at `baf9693f`)
2026-10-13	Ignore Color; the Auto Color and Outline presets, measured from here on (Outline is the first measure of Create: Strokes)
2026-10-13	Thin lines: black and white read against the image's darkest black and the paper near each edge
2026-10-13	Memory: layers traced within the box of their pixels and a few at a time (16 megapixel photo: 3.9 GB to 0.9 GB)
2026-10-13	Shared edges: outlines are cut at their junctions and each piece is fitted once, the same from either side
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
