Subject: [PATCH 1/4] Gradients: a Perceptual gradient mixes its colours in
 OKLab, and SVG and PDF write it as an image

Illustrator 30.0's gradient Method, from the public documentation
(https://helpx.adobe.com/illustrator/desktop/paint-and-fill/create-and-edit-gradients/control-perceptual-interpolation-in-gradients.html):
Classic or Perceptual; perceptual interpolation matches colour transitions to
how the eye perceives differences between colours, and perceptual gradients
are rasterised when saved as PDF or SVG.

- Gradient gains `method` (Classic | Perceptual; serde default Classic,
  written only when Perceptual, so older files open as Classic and Classic
  files are written as before). The colour crate's OKLab helpers open up for it.
- Perceptual mixes neighbouring stop colours in OKLab (sample, and
  sample_keep_model for the stroke meshes, Expand and blends); opacity stays
  linear. Renderers that mix linearly get stops on the perceptual curve,
  placed by halving each half segment where a straight line strays more than
  0.4 of a colour level (a nearly straight segment needs none). Classic
  gradients expand exactly as before.
- draws_as_pixels includes Perceptual gradients, so SVG and PDF write a
  Perceptual fill or stroke as an image at the document's raster effects
  resolution, clipped to what it paints. A gradient along or across a stroke
  stays slices (PDF no longer draws it as a within-stroke image).
- With Dither: a dithered Perceptual fill is the perceptual mix with dither's
  noise (the canvas's dithered grids are keyed by method too); SVG and PDF
  write it as an image with the noise, and a dithered Perceptual stroke as an
  image without it, as the canvas draws it (GradientPaint::pixels, SVG's
  raster_paint and PDF's area are told whether they paint a fill).

Subject: [PATCH 2/4] Gradients: the Gradient panel's Method menu and
 paint.editGradient's `method` choose Classic or Perceptual
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Illustrator 30.0's Method choice in the Gradient panel
(https://helpx.adobe.com/illustrator/desktop/paint-and-fill/create-and-edit-gradients/control-perceptual-interpolation-in-gradients.html).

- paint.editGradient takes `method: classic|perceptual` (one undo step);
  paint.setFill/setStroke take it in `gradient`, and gradient params (swatches,
  copied paints) carry it when Perceptual. Anything else is refused without
  editing. One edit can set `method` and `dither` together.
- The Gradient panel shows a Method menu (Classic, Perceptual) for linear and
  radial gradients, dimmed without a gradient; the Dither box stays under the
  stops.
- i18n: "Perceptual" where a complete catalog lacked it, and the `method`
  error in all 24 catalogs.
- Docs: G13 (estimate 14–24 h → 13–23 h, after Dither's 15–25 h → 14–24 h),
  target-app-parity (row and evidence), ui-parity, mcp.md, plugins.md.

 # Gaps
 
-> **Last reviewed:** 2026-10-10 · **Last updated:** 2026-10-22 · **Change:** minor (G8: SVG images in SVG images share one depth cap, whatever their data URL type, and SVGZ images one unpacking cap, so a crafted SVG no longer overflows the stack or unpacks gigabytes (#3562, #3563); scores and estimates unchanged; G4: colour emoji fonts with bitmap glyphs (`sbix`: Apple Color Emoji; `CBDT`: Noto Color Emoji) draw on the canvas and export: PDF Type 3 glyphs or images, SVG images with outlined text, EPS and legacy `.ai` images, Create Outlines images; COLR and OpenType SVG fonts remain; estimate unchanged; G13: gradient Dither (Illustrator 30.0): a Dither box in the Gradient panel (`paint.editGradient`/`paint.setFill` `dither`, saved in the native file) draws a linear or radial gradient fill with seeded fine noise that hides banding, on the canvas and in raster exports; SVG and PDF exports write the fill as an image at the Document Raster Effects resolution, as the public documentation describes dither; fills only, as documented; score and hours unchanged; G2: Effect › Sketch › Conté Crayon (Foreground Level, Background Level, Texture, Scaling, Relief, Light Direction, Invert; a black crayon in the dark areas and a white one in the light areas on textured mid-grey paper; ranges and defaults unverified VectorCraft choices); measured Photoshop-style filters 57/57, the Effect Gallery remains (4–6 h); Affinity import AF.5: master pages, tables, paragraph formats, shadows, glows, outlines, overlays and embedded documents; Recolor Artwork Edit chips scroll within the available screen height (#3416); small palettes retain their tab height; scores and estimates unchanged; Blend panel Type and Ramp control step easing with a separate color Shift (#2539); Blend Options retains spacing and orientation; polynomial curves are original approximations; Shape Builder Gap Detection shares Live Paint’s spatial gap finder and temporary merge bridges (#2526); Custom is capped at 72 pt in the existing options dialog; filter plug-ins read and set effect records and stroke joins, caps and miter limits, G17; 3D: original Standard, Diffuse, Top Left and Right lighting presets; command access, effective-setting recognition and preview/history; scores and estimates unchanged; G1: one selected clip group's Properties panel has Edit Clipping Path and Edit Contents at its top; the selection tools take a clipping path on its outline, over the art it clips; Polygon and Star exact-size placement remembers the chosen count for later drags and dialog openings; Cancel preserves the previous count; Live trace result bounds and selection highlights exclude the retained bitmap except in source-image views; live-effect plug-ins given their object's fills and strokes and the item they sit on, G17; plug-in parameters: labels, units, groups, help and conditions in their dialogs, text and number-list parameters, up to 256 of them, G17; exporter plug-ins: plug-in file formats in Export As and document.export, G17; G2: Effect › Artistic › Smudge Stick, Sponge and Watercolor; Sketch › Bas Relief, Charcoal, Photocopy and Stamp, #2533; Photoshop filters 45/57, 12 remaining (8–14 h); on-canvas Mirror Repeat axis, #2877; G12: Background Export progress dialog with Cancel, #2564; status-readout sample widths cached by language, document unit and pixels per point; status messages and readouts use stable responsive allocations sized for localized labels and ordinary coordinates; cached canvas dimensions match the renderer limit before cache-key creation, view construction and worker submission; cached canvas reprojection preserves scale during resize, rotation and DPI changes; on-canvas Mirror Repeat axis, #2877; G12: Background Export progress dialog with Cancel, #2564; 3D lighting: one to ten colored lights, smooth colored Inflate, legacy white-light appearance preserved; surface batching and restored seam minimum; scores and estimates unchanged; Blend spine Anchor Point conversions, selection/stacking priority and Shift regression coverage (#2544); scores and hours unchanged; transparency grid visibility saved in native documents, #1968; G6: MCP cancellation, progress notifications and busy answers during long exports, #2165, #2171, #2172; EPS editing data: legacy mesh corners, vector opacity masks and compound member paint retained; raster page comparison filters minification without relaxing limits; scores and hours unchanged; correction: quick Image Trace presets leave the panel as it was, the Image Trace button opens it; batch exporting, #1935;

+> **Last reviewed:** 2026-10-10 · **Last updated:** 2026-10-22 · **Change:** minor (G13: gradient Method (Illustrator 30.0): a Method menu in the Gradient panel, Classic or Perceptual (`paint.editGradient`/`paint.setFill` `method`, saved in the native file only when Perceptual, so older files open as Classic); Perceptual mixes a linear or radial gradient's colours in OKLab, on the canvas and in raster exports, and SVG and PDF exports write it as an image at the Document Raster Effects resolution, as the public documentation describes; Classic draws as before; a dithered Perceptual fill takes dither's noise; G13 estimate 14–24 h → 13–23 h; G8: SVG images in SVG images share one depth cap, whatever their data URL type, and SVGZ images one unpacking cap, so a crafted SVG no longer overflows the stack or unpacks gigabytes (#3562, #3563); scores and estimates unchanged; G4: colour emoji fonts with bitmap glyphs (`sbix`: Apple Color Emoji; `CBDT`: Noto Color Emoji) draw on the canvas and export: PDF Type 3 glyphs or images, SVG images with outlined text, EPS and legacy `.ai` images, Create Outlines images; COLR and OpenType SVG fonts remain; estimate unchanged; G13: gradient Dither (Illustrator 30.0): a Dither box in the Gradient panel (`paint.editGradient`/`paint.setFill` `dither`, saved in the native file) draws a linear or radial gradient fill with seeded fine noise that hides banding, on the canvas and in raster exports; SVG and PDF exports write the fill as an image at the Document Raster Effects resolution, as the public documentation describes dither; fills only, as documented; score and hours unchanged; G2: Effect › Sketch › Conté Crayon (Foreground Level, Background Level, Texture, Scaling, Relief, Light Direction, Invert; a black crayon in the dark areas and a white one in the light areas on textured mid-grey paper; ranges and defaults unverified VectorCraft choices); measured Photoshop-style filters 57/57, the Effect Gallery remains (4–6 h); Affinity import AF.5: master pages, tables, paragraph formats, shadows, glows, outlines, overlays and embedded documents; Recolor Artwork Edit chips scroll within the available screen height (#3416); small palettes retain their tab height; scores and estimates unchanged; Blend panel Type and Ramp control step easing with a separate color Shift (#2539); Blend Options retains spacing and orientation; polynomial curves are original approximations; Shape Builder Gap Detection shares Live Paint’s spatial gap finder and temporary merge bridges (#2526); Custom is capped at 72 pt in the existing options dialog; filter plug-ins read and set effect records and stroke joins, caps and miter limits, G17; 3D: original Standard, Diffuse, Top Left and Right lighting presets; command access, effective-setting recognition and preview/history; scores and estimates unchanged; G1: one selected clip group's Properties panel has Edit Clipping Path and Edit Contents at its top; the selection tools take a clipping path on its outline, over the art it clips; Polygon and Star exact-size placement remembers the chosen count for later drags and dialog openings; Cancel preserves the previous count; Live trace result bounds and selection highlights exclude the retained bitmap except in source-image views; live-effect plug-ins given their object's fills and strokes and the item they sit on, G17; plug-in parameters: labels, units, groups, help and conditions in their dialogs, text and number-list parameters, up to 256 of them, G17; exporter plug-ins: plug-in file formats in Export As and document.export, G17; G2: Effect › Artistic › Smudge Stick, Sponge and Watercolor; Sketch › Bas Relief, Charcoal, Photocopy and Stamp, #2533; Photoshop filters 45/57, 12 remaining (8–14 h); on-canvas Mirror Repeat axis, #2877; G12: Background Export progress dialog with Cancel, #2564; status-readout sample widths cached by language, document unit and pixels per point; status messages and readouts use stable responsive allocations sized for localized labels and ordinary coordinates; cached canvas dimensions match the renderer limit before cache-key creation, view construction and worker submission; cached canvas reprojection preserves scale during resize, rotation and DPI changes; on-canvas Mirror Repeat axis, #2877; G12: Background Export progress dialog with Cancel, #2564; 3D lighting: one to ten colored lights, smooth colored Inflate, legacy white-light appearance preserved;

+Illustrator 30.0's gradient Method ([public documentation](https://helpx.adobe.com/illustrator/desktop/paint-and-fill/create-and-edit-gradients/control-perceptual-interpolation-in-gradients.html)): the Gradient panel's Method menu sets
+`method` on the gradient, Classic or Perceptual (`paint.editGradient`, `paint.setFill`'s `gradient`, swatches, the native
+file; written only when Perceptual, so older files open as Classic). The documentation describes perceptual interpolation
+as colour transitions matched to how the eye perceives differences between colours; VectorCraft mixes a Perceptual
+gradient's colours in OKLab (lightness steps even, blue to yellow through a light blue-grey rather than mid grey), and
+renderers that mix linearly draw it through stops placed on that curve, more where it bends, within half a colour level.
+As documented, SVG and PDF exports rasterise it: fills and strokes are written as images at the Document Raster Effects
+resolution, clipped to what they paint (a gradient along or across a stroke as slices through the curve's stops). Classic
+gradients draw exactly as before. Freeform gradients mix their own way. With Dither, a Perceptual fill is the perceptual
+mix with dither's noise, on the canvas and in the SVG and PDF images; a Perceptual stroke's image has no noise (dither
+applies to fills). Tests: `color::gradient::tests` (perceptual midpoint, expansion, Classic unchanged, save format),
+`engine::tests_gradient::method_is_a_gradient_option_that_saves_and_loads`, `render::tests_dither`,

Review follow-up (CodeRabbit): the test's doc comment quoted a phrase from
the public help page. AGENTS.md allows feature names and a cited URL, not
copied wording; the comment now describes the behaviour itself and keeps
the URL.

Subject: [PATCH 4/4] Gradients: Expand to a gradient mesh keeps a Perceptual
 gradient's colour curve

Review follow-up (CodeRabbit): a linear gradient expands to a mesh with a
column at each stop, and the mesh mixes linearly between columns, so a
Perceptual blue -> yellow came out as the grey RGB mix in the middle.
`breaks` now also takes a column at each stop the Perceptual expansion adds
(Gradient::expanded), so the mesh follows the OKLab curve; Classic is
unchanged. the_mesh_option_makes_a_mesh_that_paints_the_gradient gains a
Perceptual case; without the change 1812 pixels differ from the gradient.
