Gert Pellin 7b0164e4e7 ICC profiles written here have their tags 4-byte aligned
moxcms's encode packs tagged elements back to back, so the built-in
sRGB profile embedded in JPEG, TIFF and PSD exports was 634 bytes with
`cprt` at offset 558, where ICC.1 §7.1.2 requires every tagged element
on a 4-byte boundary (stricter readers reject the files). encode now
lays the tag data out again with each element padded, updating the tag
offsets, the size and the profile ID (zeroed, "not computed"); tags
that share data keep sharing it. Reported to moxcms as
awxkee/moxcms#198.

bflatastic c7b46dbb3e Review: palette writing keeps the swatches PaletteFormat::holds names; ROADMAP (#1110)

dotCooCoo 2b93e8a930 Swatches: swatch.library.save counts only the swatches the file holds
swatch.library.save replied with the number of solid colors and
gradients it was asked to save, including the gradients the format
leaves out. For a new document saved as .ase, count was 50 and the file
held 46 colors. The .gpl and .ase writers keep solid colors only, and
the CSS writer leaves freeform gradients out.

count is now the number of swatches written. The new
PaletteFormat::holds returns whether a file of a format keeps a swatch
with a given paint, and swatch.library.save counts the swatches for
which it returns true. The reply has the same fields as before.

Tests: after a freeform gradient is added to a new document's swatches,
the test checks that count has these values: 51 for .vcswatches, 46 for
.gpl and .ase, and 50 for CSS. Each file holds that many swatches.

Docs: docs/mcp.md.

bflatastic 0497c9e46d #1007: Reverse Gradient mirrors off-centre midpoints
Reversal read the midpoints after Gradient::reverse had reordered the stops, so each stop
took the wrong segment's midpoint: red-to-blue with its midpoint at 20% reversed to a 50%
midpoint instead of 80%, moving the transition.

Gradient::reverse now mirrors each segment's midpoint with it, so a reversed gradient is the
same ramp the other way round; paint.editGradient's own (wrong) pass is gone, and the SVG
importer's reflect spread, which had a correct copy of the same mirroring, uses it too.

Tests: two- and three-stop gradients with off-centre midpoints sample the same reversed (t vs
1 - t) and come back after two reversals; paint.editGradient reverse turns a 0.2 midpoint into
0.8.

bflatastic 9a0183a02d Fix #831: color books (.acb) open as swatch libraries
Color books such as the Pantone books a user owns (.acb) couldn't be
opened. They are now read (never written), from public descriptions of
the format: their RGB, CMYK or Lab colors, named with the book's prefix
and suffix ("PANTONE 185 C"), as spot colors unless the book marks
them as process colors, leaving out the pages' unnamed padding. They
open from Window › Swatch Libraries › Other Library…, File › Open and
the user library folder like .ase files.

dotCooCoo a61d058f1b Swatches: Save Swatch Library writes swatch exchange (.ase) files
The Save Swatch Library dialog lists Swatch Exchange (.ase) as a
format, and swatch.library.save takes format: "ase" or a path ending
in .ase. Each solid color keeps its model (RGB, CMYK, Lab or Gray) and
its type (spot, global or process), and color groups stay groups.
Gradients and patterns are left out, and a tint swatch is written as
the color it shows. Without a path or user: true, the command returns
the file as dataBase64.

A swatch exchange library opens under the name of its file. When Save
Swatch Library or Save Graphic Style Library saves to a file, the save
panel suggests the Name from the dialog as the file name, as a save to
User Defined does, and the web app downloads the file under that name.
A name made only of dots and spaces, such as "...", gives the file name
Library (Library.vcswatches) in place of a hidden file.

palette_io::write returns the file's bytes. A property test writes
generated libraries and reads them back, and an import fuzz test loads
mutated copies of a file the writer wrote.

fastmikey99 2cdf4e3de0 Colour: ICC CMYK converts straight into the RGB profile, with black-point compensation
CMYK went to RGB through display sRGB: CMYK -> sRGB (clamped) -> working RGB.
Into a wider space (Wide Gamut RGB, the 1998 primaries) that clipped every
colour sRGB can't hold - CMYK cyan's red channel landed at 99 instead of 0 -
and the black-point compensation setting had no effect (moxcms leaves it
unimplemented). An ICC CMYK profile now converts directly into the RGB
profile: into its primaries with linear curves, where compensation is a
linear remap from the profile's black (found by sending black through the
profile and reading it back), then onto its own curves. The canvas uses the
same conversion into sRGB, so what shows is what an RGB export writes.

Checked against Ghostscript with the same profiles (relative colorimetric,
compensation on and off): exports into Wide Gamut RGB and the sRGB display
agree within 1 level in 255. The built-in CMYK spaces are unchanged (Generic
CMYK compensates in its own model).

dotCooCoo e0b1f55250 Swatches: swatch exchange (.ase) files open as swatch libraries
File › Open, Other Library… and the User Defined library folder read
.ase files. Colors keep their model, global and spot colors stay global
and spot, and color groups stay groups. The library readers take a
file's bytes. On the web, File › Open passes a swatch library file to
swatch.library.load as dataBase64 instead of as lossy UTF-8 text.

Swatch and group names in a library are now unique, in .gpl files too.
Add to Swatches puts each color group of a library into one document
group when the document already has a swatch with the group's name.
The library fuzz helpers fail when a command panics.

bflatastic ab62b5f8e8 Fix #320: CMYK images stay CMYK from PDF import to PDF export
A PDF's DeviceCMYK image opened as RGB (the interpreter's pixels as a PNG),
so every export wrote it as DeviceRGB or ICC RGB, silently. Images now keep
their CMYK samples, as CMYK colours already did:

- Model: CMYK images are blobs holding CMYK samples, a four-component JPEG
  (Adobe's inverted samples) or a Deflate CMYK TIFF. vectorcraft-doc's cmyk
  module reads their ink amounts (ImageBlob::is_cmyk, ::cmyk, capped at 64
  megapixels) and writes the TIFF (ImageBlob::cmyk_tiff).
- PDF import: DeviceCMYK, CalCMYK and four-component ICC images keep their
  samples. A JPEG with Decode [1 0 1 0 1 0 1 0] is kept byte for byte; any
  other is decoded (8 or 16 bits, its Decode array applied) and stored as a
  CMYK TIFF. Masked CMYK images and 1/2/4-bit ones open in RGB with a warning.
  Placing a CMYK TIFF keeps it CMYK too.
- PDF export: CMYK images are written in CMYK (DeviceCMYK, or ICC-based with
  the CMYK profile when colours are tagged: PDF/X-3, PDF/X-4, PDF/A). A CMYK
  JPEG neither resampled nor recompressed passes through unchanged; others are
  resampled in CMYK and compressed as ZIP or as a CMYK JPEG (jpeg-encoder,
  which also replaces the ZIP fallback and its warning for images converted to
  CMYK). Output conversion treats them like CMYK colours: Preserve Numbers and
  PDF/X-1a keep their numbers, Convert to Destination converts them to another
  CMYK profile or to RGB through a 17^4 lookup table (cms::CmykLut, now also
  behind the renderer's ink table). A CMYK image that can't be decoded is
  reported in the warnings.
- Canvas: CMYK images show through the working CMYK profile, as CMYK fills
  do, and paint their own inks in ink planes (CMYK raster exports, CMYK
  blending). SVG export writes TIFF images as PNG.

Illustrator's Output › No Conversion keeps colour data as it is
(https://helpx.adobe.com/illustrator/using/pdf-options.html).

bflatastic 33023c5a2b M4.98: freeform gradients export to SVG as images clipped to their shapes
SVG has no freeform shading: an object's freeform fill or stroke is now
written as an <image> of the colour field over its painted box, sampled
on the grid the canvas uses (twice the box's size in points), clipped to
the shape or to the stroke's outline, with the fill or stroke opacity and
blend mode on the group. Linked image mode writes the PNG next to the
SVG. Character paints keep the linear approximation (with a warning);
gradients along or across strokes stay vector slices. The grid sizing
moved to the colour crate so the canvas and the export share it.

bflatastic ffc60d5ff8 M4.59: pattern strokes and freeform gradients keep their look in PDF
Pattern strokes are written as the pattern's tiles clipped to the stroke's
outline (dashes, caps, profile, arrowheads and alignment included) instead
of mid-grey; freeform gradients on fills, strokes and type as an image of
their colour field at the document raster effects resolution, clipped to
what they paint, instead of their average colour. Both read back within
2% of the canvas at 150 ppi with no warning. Text strokes are covered for
cap, miter limit, dash array and alignment; knockout groups keep their
soft-masked form with a warning. The freeform box and grid sampling are
shared with the renderer.

bflatastic ba4ed2ff93 M4.48: JPEG Options — RGB/CMYK/gray, baseline/optimized/progressive, embedded ICC profiles and image maps
document.export {format: "jpg"} takes colorModel (rgb|cmyk|gray), quality 0–100, method
(baseline|optimized|progressive), scans (3–5), embedIcc and imageMap (none|client|server).
JPEGs are written with jpeg-encoder. CMYK files hold ink amounts drawn as the renderer's ink
planes, so CMYK colours keep their inks (black type stays black ink alone). Profiles are made
in code from the CMS (cms::icc_bytes): the RGB spaces from their primaries, the CMYK spaces as
Lab lookup tables sampled from their model, a grey with sRGB's tone curve, and loaded
profiles as loaded. Image maps write <stem>.html or <stem>.map beside the image for objects
with a URL and an Image Map shape. The JPEG Options dialog gains Color Model, Quality 0–10,
Method and Scans, Image Map and Embed ICC Profile; CMYK documents default to CMYK.

bflatastic 32252c68ea M4.28: SVG gradient export fidelity
Character gradients on live type export as url(#…) spanning the
laid-out text (point, area, on-path and outlined type, as on the
canvas); character stroke gradients span the text grown by half the
weight. Identical gradients share one def, and a swatch gradient takes
the swatch's name as its id. Midpoints are written as extra stops marked
data-vc-midpoint, which import turns back into midpoints.

Brandon Thomas 3e323bfa2a Robustness: VectorCraft never crashes — no panics in shipped code
Shipped code no longer unwraps, expects or panics: every one of the 124
unwrap()/expect()/panic!/unreachable! sites outside tests now handles the
failure (Result/Option, ?, let-else, defaults) and reports errors to the user.

- Lints: workspace clippy denies unwrap_used, expect_used, panic, todo,
  unimplemented and unreachable; clippy.toml allows them in tests, and
  integration tests, examples and testkit opt out explicitly.
- Safety net (vectorcraft_engine::guard): a panic in a top-level command rolls
  the document back and returns EngineError::Internal; a panicking tool is
  reset; the MCP server answers with an internal error and keeps serving; the
  UI frame and each control request are guarded.
- APIs that hid failures now return them: Rendered::to_png/to_jpeg/to_webp
  return Result (JPEG/WebP errors used to write empty files),
  FontDb::face returns Option, Region::top returns Option.
- Fuzzing: engine/tests/import_fuzz.rs feeds garbage, hostile and mutated SVG
  and PDF through import → render → export (30k cases locally, no panics).
- Docs: AGENTS.md/CLAUDE.md rule, docs/development.md "Robustness" section,
  README pointer and a PR template checklist.

bflatastic 025d758abe M3.83: gradients within, along or across a stroke
The Gradient panel's Stroke buttons now work: with the Stroke proxy on a
linear or radial gradient they lay it within the stroke (placed on the
page, as before), along the path (start to end of each subpath) or across
it (left edge to right edge; inside/outside strokes span their visible
side). `paint.editGradient {stroke: true, strokeMode}` sets it (new art
too with nothing selected); `document.inspect` reports
strokeOptions.gradientMode. Model: StrokeLayer.gradient_mode (default
Within, not written).

Shared geometry in effects::stroke::gradient: ribs on the bisectors of
the flattened path (fans round sharp corners, widened under arrowheads,
following width profiles) cut slices each painted with a linear piece of
the gradient (Gradient::span). The canvas and raster export clip them to
the stroke's outline and arrowheads, grown a pixel and composited with
copy so there are no seams and translucent stops paint once. SVG and PDF
write the same slices clipped to the outline, with a warning (new
vectorcraft_svg::export_with_report). Outline Stroke and Expand make
gradient meshes clipped to the outline. Mesh quads now grow along their
edges so thin quads show no seams. Dashes, profiles and arrowheads keep
working in both modes.

bflatastic be648089be M3.96: Color Themes panel with a local theme library
Window → Color Themes: the Create tab makes a five-colour theme on a

kept in the preferences (Prefs::color_themes; no online service).

Commands: colorTheme.list, colorTheme.save {colors | color + rule, name?,
replace?}, colorTheme.delete, colorTheme.addToSwatches. Harmony::theme
and move_on_wheel live in the colour crate; the wheel is now a shared

bflatastic 81582c8d4f M3.95: Color Guide Limit to Library and Edit or Apply Colors without art
The Color Guide's library button opens a Limit to Library popup (None,
Document Swatches, the colour libraries): every harmony colour and
variation snaps to the nearest colour there (CIEDE2000), cached per
inputs so the grid isn't re-snapped every frame. `color.harmony` takes
`limitTo`, `ui.colorGuideLimit` sets the panel's limit, and Recolor
Artwork's Limit to Library also offers the document's swatches (one
shared engine helper, swatchlib::limit_palette).

Edit or Apply Colors opens Recolor with the harmony colours limited to
the same library; with no art selected the colours are the rows and OK
saves them as a new colour group.

bflatastic d8eff17b9f M3.98: radial annotator extent ellipse, aspect handle and off-centre focal point
Radial gradients show a dashed extent ellipse: its handle across the bar
sets the aspect ratio, the ellipse elsewhere rotates it, and the dot inside
the centre ring drags the focal point (GradientGeom.focal) for an off-centre
radial. paint.setGradientGeom takes aspect (%) and focal ([x,y] | null), and
start/end may be left out; the focal point keeps its place in the ellipse as
the vector, aspect and object transform. It renders as a two-point radial,
exports and imports as SVG fx/fy and PDF two-point radial shadings, expands
to off-centre rings, and travels in gradient params and the native format.

bflatastic 9537eca5f7 M3.90: blend modes and opacity composite inks in CMYK documents
A CMYK document that shows transparency is drawn once per ink plane
(complemented C, M, Y; complemented K as a grey) so every blend mode,
opacity, group, knockout and effect composites inks, PDF-style; the
planes' inks are shown through the working CMYK profile (cached 4-D XYZ
table). Cyan multiplied over magenta now shows C100 M100. Opacity masks
keep screen luminance; RGB colours and placed images are separated
first. RGB documents and opaque CMYK documents keep the screen-colour
path.

PDF export of CMYK documents writes its transparency groups with
/CS /DeviceCMYK (luminosity mask groups stay RGB) and puts top-level
transparency in a non-isolated page-wide group so it blends in CMYK too.
Flatten Transparency composites CMYK documents ink by ink and makes CMYK
regions. Non-separable modes no longer give NaN for greys.

Colours gain a CIE Lab model (`Color::Lab {l,a,b}`, serde tag `lab`), handled through the
CMS (display, separation, conversions, gamut), tints (toward paper white), keep_model, harmonies,
recolouring, blends, Info and the Color panel. Swatch Options gets a Lab mode

Swatches panel → Spot Colors… (`ui.spotColors`, dialog `spotColors`) runs `swatch.spotOptions
{useLab}` (Document.spot_use_lab, default on): Lab spot colours show and separate from their Lab
values, or art linked to them takes their working-CMYK equivalents, as one undo step. PDF export

or a DeviceCMYK one with CMYK equivalents.

bflatastic b2ececc7b4 M3.59: tints of global and spot colours, tint swatches and Global colour balance
A colour linked to a global or spot swatch keeps a tint (Paint::Solid.tint, 1 by default and
left out of files at 100 %): paint.setFill/setStroke {swatch, tint} apply the swatch at that
percentage, swatch edits recolour every linked colour at its own tint, and Color::tinted
resolves it (CMYK and Gray inks scale, RGB mixes toward white). swatch.new saves a tint as a
tint swatch ("Ink 40%") linked to its base. Spot tints separate as that percentage of their
plate (Separations Preview, PDF Separation value) instead of an ink-ratio guess. Adjust Color
Balance's Global mode (tint) shifts the tints of linked colours. The Color panel shows Tint
mode (the swatch chip, its name and a T slider) for linked colours; the Swatches panel
highlights the tint swatch in use. Gradient stops get the same link and tint fields (the
swatch walks cover them), so GradientStop is no longer Copy.

luminance from sRGB values (color-interpolation="sRGB"), as the canvas does.

Tests: a per-mode table on the canvas (object, fill and group blend modes,
within 1/255; Exclusion 2/255 in the rasteriser's 8-bit pipeline), the same
table through SVG export rendered by resvg, clip and invert masks against the
canvas, and every mode's PDF name read back.

bflatastic bfebf66404 M3.53: Color Guide has 21 harmony rules, Steps and Variation options, a fixed base colour and Save Colors as Swatches
The harmony rules (Complementary 1/2, Split Complementary, Left/Right Complement, Analogous 1/2,
Monochromatic, Shades, Triad 1-3, Tetrad 1-3, Compound 1/2, High Contrast 1-3, Pentagram) live in
the color crate with our own math, base colour first. The variation grid moves there too
(`harmony::Guide`): a row per harmony colour with the colour in the centre column, shades/cool/muted
to the left and tints/warm/vivid to the right, 1-20 steps and a variation amount.

- `color.harmony {color, rule, steps?, variation?, amount?}` query returns {rule, colors, grid}.
- The panel keeps its base colour until "Set base color" takes the current one; Shift/Cmd-click
  selects several cells and Save Colors as Swatches saves them (`swatch.new {colors}`, one step).
- Color Guide Options dialog (`ui.colorGuideOptions`, kind `colorGuideOptions`) with a preview row;
  the options persist in `UiState::color_guide`.

bflatastic f48ba26380 M3.32: the document colour mode governs new colours
A CMYK document (file.new {colorMode: "cmyk"}, Document::new_with_mode)
starts with CMYK default swatches (default_swatches(model)), and RGB
colours and gradient stops applied to it are stored as CMYK (Gray stays
Gray) unless paint.setFill/setStroke get keepModel; the Color panel keeps
the model picked on its sliders. RGB documents keep colours as given.
Harmonies and Color Guide variations keep the base colour's model, Recolor
Artwork the replaced colour's, and Edit Colors blends between models take
the document's, through a shared Color::in_model / keep_model.

bflatastic 93640efb36 M3.34: copied appearances place their gradients on the target's own bounds
The eyedropper (`appearance.copyFrom`), `graphicStyle.new` and `graphicStyle.apply` move placed gradients so they
sit at the same place relative to each target's bounds (type: its layout box in text space) instead of where the
source had them; the paint defaults take the gradient unplaced, so new art fits it. Model: `GradientGeom::rebase`
/ `GradientPaint::rebase` (color), `Appearance::rebase_gradients` (strokes relative to their inflated boxes) and
`GraphicStyle::unit_box`: new styles store placed gradients in unit-box space; styles from older files keep
document coordinates and apply as before.

bflatastic 059f623410 M3.33: Gradient panel: proxy, swatch menu, diamond location, stop popover, Alt-drag copies and swaps, swatch drops, stop eyedropper
The Gradient panel gains the Fill/Stroke proxy, a thumbnail menu of the document's gradient swatches with Save to
Swatches, Angle and Aspect Ratio fields with preset menus (the shared spin field), Show/Hide Options, and a stop
colour row whose eyedropper samples the next colour clicked on art into the selected stop (Eyedropper tool option
`stop`, `paint.sampleColor {stop}`). On the slider a selected midpoint diamond shows and sets its midpoint in
Location, double-clicking a stop opens the shared stop popover, Alt-drag copies a stop and Alt-dropping it on
another swaps their colours (`swap_stop_colors`), and a dropped colour swatch adds or recolours a stop. Clicking a
stop no longer falls through to the add-stop strip. Swatch tiles and the gradient thumbnail drag onto art, which
paints the object under the pointer through `paint.setFill`/`paint.setStroke {ids}`. The panel, the popover and
the Color panel share one stop-writing helper.

bflatastic 3786cfaf36 M3.17: interactive gradient annotator — drag the start handle or the bar to move the gradient, the end handle to change length and angle, just past the end to rotate (Shift snaps to 45°); a bar click adds a stop, stops drag along the bar, off it to delete (never below two), Alt-drag copies, diamonds move midpoints; a click inside selected art applies the gradient from that point; double-clicking a stop opens a popover (Color/Swatches, Opacity, Location); the selected stop lives in the session (gradient.selectStop), shared by the tool, the Gradient and Color panels and agents, and takes Delete/Backspace and ←/→ ahead of their shortcuts (Tool::claims_key, also headless); stop chips draw as Overlay::Swatch with generated add/remove-stop cursors; the stop math moves into the color crate

bflatastic 016fcbf34e M3.7: neutral paint, effect and stroke labels
The wide-gamut RGB working space is now "Wide Gamut RGB (1998 primaries)";
its old name still resolves everywhere (cms::profile / canonical_name,
Color Settings, Assign Profile, documents and settings saved earlier).
The Effect menu section is "Vector Effects", stroke width profiles are
Lens / Taper Start / Taper End, dash, arrowhead-tip and gradient-on-stroke
tooltips are reworded, the Window library submenus hold neutral disabled
placeholders until the generated libraries land, and the Swatches menu
offers "Save Swatch Library…" (disabled).

Brandon Thomas 4878f1c5dd Rename DrawCraft → VectorCraft: crates (vectorcraft-*), apps, binaries, types, env vars, docs, examples (.vectorcraft); old .drawcraft files and preferences still load. Fix: text bounds exact after opening a file; selection no longer marks a document modified (dirty = content differs from the saved document). Screenshots and renders regenerated.
