bflatastic 62036eac6c Image Trace: Flat Logo takes the tones of an unevenly lit colour for one colour

A scan's paper is a tenth darker in one corner than in another. Flat Logo found
each tone of it as a colour of its own and traced the bands and the specks
between them: on the scanned inputs 470 paths, 21 px from the art on average.

Two palette colours are now one when the pixels between them are no fewer than
a third of those at the lesser of the two: flat colours leave only their shared
edge between them, tones of one colour fill the gap. Whether the image is flat
art at all is still asked of the tones as found.

Flat Logo on its inputs, all sizes and variants: 3.106 -> 0.090 px off on
average, 88.5 -> 0.82 px at most, 69.9 -> 3.9 paths; clean, aliased, blurred
and noisy art as before.

Image Trace quality

Last reviewed: 2026-10-13 · Last updated: 2026-10-13 · Change: minor (Flat Logo on scans: 470 paths and 21 px off to 8.5 paths and 0.09 px)

What Image Trace (crates/trace) makes of images whose right answer is known, measured by a harness and compared with the numbers before each change. Nothing here is a judgement by eye, and nothing is compared with any other product except the open tracer named under Yardstick.

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
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
askew shapes	a rectangle, a plus sign and two lines, each 1 to 2 degrees off level and upright
plain shapes	a circle, a rectangle, a square, a rounded rectangle, an ellipse and a hexagon, each alone on white (measured from the Shapes change on, not at the baseline)
linear gradients	a two-stop gradient over the whole image at 25 degrees, and a three-stop gradient at 110 degrees in a disc on white: their lines and stops are known (measured from the Gradients change on, not at the baseline)
flat colour art	a disc of two halves in different colours that touch; a badge of four colours on white
gradient, photo	a smooth two-way gradient with a glow; a photo-like image (soft-edged shaded objects, texture, sensor noise)

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)
grouped %	with Auto Grouping on, the share of the paths that were put inside another (the picture is painted in the grouped order for every other measure of that row, so 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

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.

Revision history

date	change
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
