bflatastic a6d5c461a1 Fix #1724: 3D effects on a nonzero compound path keep the area its contours fill
Extrude & Bevel, Inflate and Rotate built their solid from the outline by
nesting alone: a contour inside an odd number of others was a hole. Under the
nonzero rule a contour inside another that runs the same way encloses filled
art, so the effect cut a hole the object doesn't have. The fill rule now
reaches the outline builder, which leaves out contours with filled art on
both sides before pairing outlines and holes.

bflatastic 779120cb5b Fix #1705: a Transform effect's copies are bounded by the anchors they make
Each Transform effect clamps its own copies to 1000, but each copies all of
what the effect before it made: three of them on one square ask for a
thousand million squares, from a small file. Copies now stop where the result
would pass two million anchors (1000 copies of a 2000-anchor path).

Ayberk A. 043b446b94 3D and Materials: the light takes the documented settings
The public 3D and Materials panel options give the Light Settings as
Intensity (0–100 %), Rotation (-180° to 180°), Height (0° to 90°),
Softness (0–100 %) and Ambient Light (0–200 %), with the light moved to
the back or the front of the object. The 3D effects (Revolve included)
had Direction and Elevation (an azimuth and elevation), Intensity and
Ambient (0–100 %).

- Rotation turns the light round the object on the page (our reading:
  0° on its right, counterclockwise); Height raises it from beside the
  object (0°) to straight in front (90°); Light behind the object puts
  it at the back. The light gizmo's ring and line are Rotation and
  Height.
- Softness wraps the light round the object: at 0 % it falls off with
  the angle as before, at 100 % it reaches nothing only straight away.
- Ambient Light runs to 200 %; faces stay no brighter than the art.
- lightRotation, lightHeight, lightBehind and lightSoftness replace
  lightAzimuth and lightElevation. An earlier light is read as the same
  direction, so it shades exactly as before (old and new code give the
  same colours for the four effects and five lights); effect.setParams
  turns a stored one into the new form before applying new values, and
  the parameter description names lightAzimuth and lightElevation as the
  earlier form, so effect.apply and effect.setParams still take them. The
  default light is the earlier default's: Rotation 125.26°, Height 30°.
- The dialog's Lighting tab shows the settings in the documented order;
  Softness, Ambient Light and Light behind the object are in every
  catalog, and the unused Direction, Elevation and Ambient are gone.

Light colour, presets, several lights and shadows are not built.

Ayberk A. 39db6abfce 3D and Materials: Perspective runs 0° to 160°, as documented
The public 3D and Materials panel options give Perspective as 0° to 160°
("how close or far the object appears"); it was a 0–100 % strength, for
Revolve, Extrude & Bevel, Inflate and Rotate alike.

- The eye stands where a sphere about the object's centre, √3 times its
  half size (the box around it fits inside), fills that angle of the
  view: 0° is none, wider brings the eye nearer, and at 160° it is just
  outside the sphere, never inside the object. The documentation doesn't
  say how the angle places the eye; docs/three-d.md says this is our
  reading.
- `perspectiveAngle` (degrees) replaces `perspective` (%). A strength from
  an earlier file or script is read as the angle that shows exactly the
  same view: sin(angle / 2) = √3 × strength / 4, 100 % about 51.3°. An
  angle given too wins. effect.setParams turns a stored strength into the
  angle before applying new values. The parameter description names
  `perspective` as the earlier form, so effect.apply and effect.setParams
  still take it under the key check of #1592. Old and new code draw the four effects identically at 0, 25,
  60 and 100 % (bounds equal to 1e-9).
- The dialogs' Perspective fields run 0–160°.

Gert Pellin 85335e9e14 Scribble: one zig-zag per region, no lines across holes and notches (#1648)
The rows' spans were all chained into one polyline, so where a row had
more than one span the line ran across the hole between them, outside
the shape. A span now continues the previous row's chain whose
connecting line stays inside the shape (the nearest one); otherwise it
starts a chain of its own. In a convex shape the connector always stays
inside, so the result there is unchanged (render goldens pass).

Gert Pellin 977b8fb642 Roughen (Smooth): a turn-back stays smooth instead of becoming a cusp (#1643)
Roughen's jitter can put a point behind its predecessor, so the path
turns back. The Catmull-Rom tangent next - prev then shrinks to almost
nothing and the anchor becomes a cusp, which PDF viewers (MuPDF,
poppler, Ghostscript) draw with a miter spike; the preview doesn't.

catmull_rom now keeps the tangent at least half as long as the longer
chord, and where it is shorter (turns of more than about 150 degrees)
points it along the bisector of the two chords: the turn becomes a round
hairpin. Gentler turns keep the plain Catmull-Rom tangent, so Zig Zag,
Scribble and the render goldens are unchanged.

Gert Pellin a169693817 Warp › Arc: bend in the object's real proportions
warp_point worked on box coordinates normalised to -1..1 on both axes:
Arc's radius was in x units but its edges were offset in y units, so a
box that isn't square bent into no circular arc (skewed sides from
Bend 10 %), and at 100 % the radius (2/π) was smaller than the
half-height, folding the inner edge over. warp_point now takes the
box's aspect along the warp; Arc keeps the centre line's length on a
circular arc in real proportions, with concentric edges, and an inner
edge that would pass the centre stops there. Other styles are as they
were; a square is bent as before.

Ayberk A. 15cef94ba6 3D and Materials: Inflate takes Twist, Taper and Cap
The public 3D and Materials panel options list Depth, Twist, Taper and Cap
for every 3D type; Inflate had only Depth.

- Twist (0° to 360°) and Taper (1–100 %) turn and scale the back about the
  shape's centre, as Extrude & Bevel's do: a puffed back is turned and
  lowered in proportion, and the sides follow in slices.
- Cap: Solid closes the back; Hollow leaves it off, so the inflated front is
  a shell open behind. The documentation doesn't say what Cap means for
  Inflate; this reading is stated in docs/three-d.md.
- The dialog's Object tab shows them in the documented order (Depth, Twist,
  Taper, Cap), then Volume and Both sides.

At 0 % volume a twisted, tapered Inflate has the extrusion's outline from
every side (tested).

A twisted, tapered, hollow Inflate draws on the canvas exactly as it
exports, and expands to faces with their own ids (tested). ROADMAP and the
parity pages list the new options; the 3D score stays at ~25 %.

The public 3D and Materials panel options give Twist as up to 360°; it took
-360° to 360°. Values beyond either end now hold at that end (the effect is

Ayberk A. 8a3458a974 Effect › 3D and Materials: Extrude & Bevel, Inflate and Rotate
The three 3D types besides Revolve, as live effects in the three-d crate,
drawn as shaded vector faces by the canvas, SVG/PDF export and Expand
Appearance alike, from the public 3D and Materials documentation:

- Extrude & Bevel: depth (0-2000 pt), twist, taper, solid or hollow caps,
  and bevels in six original cross-sections (classic, rounded, cove, step,
  ogee) with width, height, repeat, spacing, inside and both sides.
- Inflate: the shape as a membrane under pressure (a Poisson solve held at
  zero along the outline and holes), so it rises vertically from the edge
  and rounds without creases; volume, depth and both sides. Steep cells
  near the outline are refined without cracks.
- Rotate: every fill and stroke turned in 3D and shaded as one plane.

All three share Revolve's view and lighting parameters, the rotation and
light gizmos (turning about the art's centre) and a dialog with Object,
Rotation and Lighting tabs, with Position presets (Front ... Isometric
Bottom, our own values). An object takes one 3D effect. Inflate cuts the
grid cells that straddle a hole's edge with pathops, hence the new
pathops -> three-d layer order.

Docs: docs/three-d.md, mcp.md, and the 3D rows of the parity docs.

bflatastic 1168c319b0 Close the hole whenever the inner offset of a closed stroke has crossed over
The check added for #1396 dropped the inner contour only when the path itself fell in the hole, which takes a stroke more than twice as wide as the shape. Between one and two times the size (a 30 pt ellipse with a 50 pt stroke), and on rectangles with round or bevel joins, the hole stayed.

An offset contour is now left out when no point of it lies half the weight from its subpath: it is then nowhere the edge of the stroke. Subpaths are judged one by one, and only when the stroke is at least as wide as the subpath's bounds, so ordinary strokes take the same single call as before.

Vikram Bhaskaran aed5d380e9 Cover a small rectangle in the fat-stroke test. 2026-10-12 20:09:53 +07:00
Vikram Bhaskaran b4c1cdbcea Fill the hole a stroke leaves when it is wider than the closed shape.
A closed path stroked wider than it is came back as a ring, because the inner offset crossed the middle. When that outline no longer covers the path, the outer contour is kept so the stroke paints solid.

arhammusheer 5beac4f122 #1244: smaller objects: Node 352 -> 152 bytes, NodeKind 200 -> 80, and a cheaper undo estimate
Rarely set fields move into one optional boxed NodeExtras, and large NodeKind payloads (images,
live shapes, blends, envelopes) are boxed. Every object, and every undo step that copies it,
shrinks: a 50k-path move keeps ~24.5 MB per step instead of ~40 MB. Files stay byte-identical
(Node keeps its flat JSON through a borrowed Serialize and a from-wire Deserialize, no flatten),
and loading is slightly faster. Undo and redo reuse their step's size estimate instead of
walking the document again (8.3 -> 5.6 ms for a 50k-path move).

arhammusheerandClaude Opus 5.5 0724aafbb6 #1172: share an object's appearance with its undo history until it changes
Every edit of an object copied its whole appearance (its fills, strokes and effects, about
540 bytes for a basic object) into the new node, though a move leaves it as it is. Over 45
whole-selection moves of 10,000 paths, undo history grew by 589 MB; now 349 MB (41 % less), and
a nudge or a drag of the selection takes 12 ms instead of 15.

- Node::appearance is a vectorcraft_doc::Shared<Appearance>: copy-on-write. A clone shares it,
  and the first change through DerefMut copies it (Arc::make_mut). Reads, writes, equality (also
  against a plain Appearance) and the saved form are those of the Appearance itself, so call
  sites read and change it as before. Sites that build or assign a whole appearance add .into(),
  and the few that need a plain copy take (*n.appearance).clone().
- Node::transform changes the appearance only when it has gradients to transform, and pattern
  paints are transformed only when there are some: a move no longer copies an appearance it
  doesn't change.

The workspace suite (5,301 tests) and clippy pass with the change; the doc and engine suites
pass again after the transform guard.

bflatasticandClaude Opus 5.5 59c890df9e Part of gap 2: Effect › Brush Strokes (Accented Edges, Angled Strokes, Crosshatch, Dark Strokes, Ink Outlines, Spatter, Sprayed Strokes, Sumi-e)
Eight raster effects on the pixel-filter pipeline
(vectorcraft_effects::pixel::brushstrokes), under a new Effect › Brush
Strokes submenu between Blur and Distort in the Raster Effects section:

- Accented Edges (edgeWidth pt 1..14, default 2; edgeBrightness 0..50,
  38; smoothness 1..15, 5): the edges of the softened object painted
  towards white chalk at high brightness or black ink at low brightness;
  Smoothness also leaves the faint edges out. The shape stays as it was.
- Angled Strokes (directionBalance 0..100, 50; strokeLength pt 3..50, 15;
  sharpness 0..10, 3): light areas in right diagonal strokes, dark areas
  in left diagonal ones; 0 makes every stroke a left diagonal, 100 every
  stroke a right diagonal. Sharpness brings detail and bristles back.
- Crosshatch (strokeLength pt 3..50, 9; sharpness 0..20, 6; strength
  1..3, 1): the detail kept under pencil hatching along both diagonals,
  Strength passes of it, the edges roughened.
- Dark Strokes (balance 0..10, 5; blackIntensity 0..10, 6;
  whiteIntensity 0..10, 2): short strokes towards black in the dark
  areas, long strokes towards white in the light areas.
- Ink Outlines (strokeLength pt 1..50, 4; darkIntensity 0..50, 20;
  lightIntensity 0..50, 10): black outlines over the edges, ink hatching
  in the shadows, shadows darkened and highlights lightened.
- Spatter (sprayRadius pt 0..25, 10; smoothness 1..15, 5): each pixel
  shifted by noise up to 0.4 x the radius; Smoothness makes the grains
  larger and smoother.
- Sprayed Strokes (strokeLength pt 0..20, 12; sprayRadius pt 0..25, 7;
  strokeDirection Right Diagonal, Horizontal, Left Diagonal or Vertical):
  strokes along the direction, scattered by up to 0.3 x the radius.
- Sumi-e (strokeWidth pt 3..15, 10; strokePressure 0..15, 2; contrast
  0..40, 16): wet strokes, ink bleeding from the darks along paper
  fibres, more ink with pressure and an S-curve contrast for rich blacks.
  It works in value only: hues and saturation stay, and so does the
  object's shape (no fringe in the transparency).

A stroke averages the colour along a segment through the pixel (16
samples at most, the art softened first when they lie more than a pixel
apart); strokes lie in rows around the object's centre, each row
starting at random and each stroke shifted along itself, with streaked
noise for the bristles. Everything is in document space, so the effects
look the same at any zoom or resolution, move with the object and draw
the same every time; outsets and reaches are exact. On a 2000 x 2000
raster in release the slowest settings take 0.3-2.0 s (Crosshatch at
50 pt with 3 passes the most).

Shared helpers instead of copies: edges::sobel (Glowing Edges now uses
it, unchanged), distort::displace and texture::Tones are pub(super).

Catalogue rows with parameter docs, menu entries, Sprayed Strokes'
direction dropdown, translations (de, es, fr, it, ja, ru, uk, zh-hans,
zh-hant; menu labels in cs and pt-br), tests (parameters and clamping,
outsets and reaches, each filter and option showing, chalk and ink on
the edges only, shadows and rich blacks, Sumi-e keeping the shape and
hues, hatching keeping the tone, strokes smearing along their direction,
Spatter's radius, resolution and move invariance, canvas, multithreaded,
PDF and SVG, the command sweep with junk parameters, the menu) and
ROADMAP.

bflatasticandClaude Opus 5.5 8a0cd9dbf6 Part of gap 2: Effect › Distort (Diffuse Glow, Glass, Ocean Ripple)
Three raster effects on the pixel-filter pipeline
(vectorcraft_effects::pixel::distort), under a new Effect › Distort
submenu between Blur and Pixelate in the Raster Effects section (the
vector Distort & Transform stays its own submenu):

- Diffuse Glow (graininess 0..10, default 6; glowAmount 0..20, 10;
  clearAmount 0..20, 15): the highlights, softened over 2 points, glow
  white from the brightness Clear Amount leaves clear; white grain as
  dense as Graininess says is sprinkled over the object, thicker in the
  glow. Transparency stays as it was.
- Glass (distortion 0..20, 5; smoothness 1..15, 3; texture Blocks,
  Canvas, Frosted or Tiny Lens, default Frosted; scaling % 50..200, 100;
  invert): the object seen through a glass surface; each pixel takes the
  colour the surface's slope bends it to, sampled between pixels. Slopes
  are taken over a span Smoothness widens. The surfaces are made in code
  (Canvas is Texturizer's weave); Load Texture is left out.
- Ocean Ripple (rippleSize 1..15, 9; rippleMagnitude 0..20, 9): smooth
  noise ripples about Ripple Size + 2 points across shift the object by
  up to 0.03 x magnitude x their size.

The shifts are capped, so the effects' outsets and reaches are exact,
and every surface lies in document space around the object's centre:
the same at any zoom or resolution, moving with the object, identical
on every redraw.

Catalogue rows with parameter docs, menu entries, the Texture dropdown,
translations (and German's missing Canvas), tests (parameters and
clamping, outsets, each texture and Invert, the ripples' reach, the glow
and its grain, resolution and move invariance, canvas, multithreaded,
PDF and SVG, the command sweep with junk parameters, the menu) and
ROADMAP.

bflatasticandClaude Opus 5.5 30ba774e6f Part of gap 2: Effect › Texture (Craquelure, Grain, Mosaic Tiles, Patchwork, Stained Glass, Texturizer)
Six raster effects on the pixel-filter pipeline
(vectorcraft_effects::pixel::texture), under a new Effect › Texture
submenu between Sharpen and Video in the Raster Effects section:

- Craquelure (crackSpacing pt 2..100, default 15; crackDepth 0..10, 6;
  crackBrightness 0..10, 9): the object on relief plaster that cracks into
  plates about Crack Spacing apart (a Voronoi network over jittered points)
  and along the quarter, half and three-quarter contours of its softened
  tones. Depth sets how dark and wide the cracks are and how high the
  plates' bevels and the tones stand (lit from the top left); Brightness
  how brightly the surface is lit.
- Grain (intensity 0..100, 40; contrast 0..100, 50 = unchanged; grainType
  Regular, Soft, Sprinkles, Clumped, Contrasty, Enlarged, Stippled,
  Horizontal, Vertical, Speckle; default Regular): coloured 1-point grains,
  smooth ones, clumps, 2-point grains, streaks along rows or columns, dark
  specks; Sprinkles and Stippled use the background colour, white.
- Mosaic Tiles (tileSize pt 2..100, 12; groutWidth 1..15, 3; lightenGrout
  0..10, 9): irregular tiles bevelled at their edges, with sunken grout half
  a point wide per step, lightened as Lighten Grout says.
- Patchwork (squareSize pt 0..10, 4; relief 0..25, 8): squares filled with
  the colour around their centres, raised to heights that follow the
  highlights and shadows, a little more or less at random.
- Stained Glass (cellSize pt 2..50, 10; borderThickness 1..20, 4;
  lightIntensity 0..10, 3): single-coloured panes leaded in the foreground
  colour (black, half a point per step), lit from behind at the object's
  centre and fading out towards its corners (PixelSpace gains `extent`).
- Texturizer (texture Brick, Burlap, Canvas, Sandstone, default Canvas;
  scaling % 50..200, 100; relief 0..50, 4; lightDirection Bottom, Bottom
  Left, Left, Top Left, Top, Top Right, Right, Bottom Right, default Top;
  invert): the object on a surface in relief. The four surfaces are height
  fields generated in code (bricks in stretcher bond, plain weaves coarse
  and fine, octaves of smooth noise); no image files. Load Texture is left
  out.

Every pattern lies in document space around the object's centre, so the
result is the same at any zoom or raster resolution, moves with the object
and is identical on every redraw (hash noise of cell indices); slopes are
taken in document units. Work per pixel is bounded (a 5 x 5 cell search,
four or five height samples, box blurs); parameters are clamped to their
ranges and finite-checked. The Pixelate helpers (Place, the cell search,
the softened colours) are shared, Mezzotint uses the shared smooth noise,
and the effect dialogs' dropdowns translate their labels in an "effect"
context where the plain word means something else (Soft, Horizontal and
Vertical are type settings in Japanese and Chinese).

Catalogue rows with parameter docs, outsets and reaches, menu entries,
dropdowns (Grain Type, Texture, Light Direction), translations, tests
(parameters and clamping, cracks and contours, ten distinct grains, tiles
and grout, squares in relief, leaded panes and the centre light, the
textures lit and inverted, the same at twice the resolution and when
moved, canvas, multithreaded, PDF and SVG, the command sweep with junk
parameters, the dialogs and the menu) and ROADMAP.

Adds the Video group to the raster effects, after Sharpen:

- De-Interlace…: Eliminate Odd or Even Fields, Create New Fields by
  Duplication or Interpolation. The fields are the rows of the document's
  raster grid (Document Raster Effects Settings › Resolution, carried to
  the filters as PixelSpace::line) counted from the top of the page, so
  the result is the same at any zoom and moves with the page. A line
  taken out copies the line above (the one below at the top), or takes
  the average of the two.
- NTSC Colors (no options, applied at once): colours a composite
  television signal can't carry, with luma plus chroma past 110 % of white
  or luma minus chroma below -20 % in YIQ, have their chroma cut to fit,
  keeping their luma. Saturated yellow, cyan and pure red lose some
  saturation; legal colours stay as they are.

bflatasticandClaude Opus 5.5 9bad0a24ca Part of gap 2: Effect › Pixelate (Color Halftone, Crystallize, Mezzotint, Pointillize)
Four Photoshop-style raster effects on the pixel-filter pipeline
(vectorcraft_effects::pixel::pixelate), under a new Effect › Pixelate
submenu between Blur and Sharpen in the Raster Effects section:

- Color Halftone (maxRadius 4..127, default 8; channel1..channel4 screen
  angles -360..360, defaults 108/162/90/45): each colour channel is
  screened at its angle in square cells sized so a dot of Max. Radius
  fills one; each cell's dot covers the share of the cell that is the
  channel's coverage-weighted mean there (white stays white, black
  black). RGB documents screen R, G, B (channels 1 to 3); CMYK documents
  screen C, M, Y, K inks (channels 1 to 4), also when they are drawn ink
  plane by ink plane (the K plane uses channel 4).
- Crystallize (cellSize 3..300, default 10): every pixel takes the
  colour at the nearest of one jittered point per cell (exact Voronoi
  over a 5 x 5 neighbourhood, pruned by distance).
- Mezzotint (type: Fine/Medium/Grainy/Coarse Dots, Short/Medium/Long
  Lines, Short/Medium/Long Strokes; default Fine Dots; a dropdown in the
  dialog): each channel is turned fully on or off against its own random
  threshold pattern, so the object becomes pure colours.
- Pointillize (cellSize 3..300, default 5): one dot of random size per
  cell at a jittered point, coloured by the softened object there and as
  opaque as the object at its centre, stacked in random order over a
  white canvas where the object is.

Lengths are in points (Scale Strokes & Effects scales them) and every
pattern lies in document space around the object's centre, so the
result is the same at any zoom or raster resolution, moves with the
object, and is identical on every redraw (hash noise of the pattern's
cell indices, no state). Work per pixel is bounded whatever the
parameters, which are clamped to their ranges and finite-checked; the
halftone's cell grid is capped by the raster's size and a screen finer
than 3 pixels leaves the image as it is (its average). PixelSpace gains
`channels` so the renderer tells the filters what the channels hold.

Catalogue rows with parameter docs, outsets and reaches for cropping,
menu entries, dialog labels (Max. Radius, Channel 1-4, Cell Size), the
Mezzotint Type dropdown, translations, and tests: parameters and
clamping, tone and coverage, CMYK inks, polygon crystals, pure-colour
mezzotints with ten distinct patterns, dots on a white canvas, the same
result at twice the resolution and when moved, the canvas, PDF and SVG
through the engine, the command sweep with junk parameters, the dialogs
and the menu.

bflatasticandClaude Opus 5.5 20e5a746bd Part of #885: the Transform effect's dialog takes Transform Each's controls
Effect › Distort & Transform › Transform… was a plain list of fields.
It now has Transform Each's layout: Scale and Move with sliders, Rotate
with an angle dial, then Copies, Reflect X and Y, the reference point and
Random, kept with the effect so editing it from the Appearance panel
shows them again.

- The effect scales, rotates and reflects about the chosen point of the
  9-point grid (`reference`, the centre by default).
- Random takes a share of each value, drawn from the object's id: each
  object varies its own way and keeps its result on every redraw; a
  group's members move together.
- Copies stop before one reaches past 1e9 pt, and the scale and move are
  capped, so large values can't overflow.
- Transform Each and the effect share the sections and options code; the
  angle dial is a new widget.
- A plain number field now takes the focus when it is a dialog's first
  field, so both dialogs open with Scale › Horizontal ready for typing.

Transform Objects, Transform Patterns and Scale Strokes & Effects are not
in the effect yet: the geometry effects reshape paths only.

bflatasticandClaude Opus 5.5 99671cabd8 Fix #827: shadows and glows keep their blend modes in PDF
A raster effect painted below its object (Drop Shadow, Outer Glow) is
written as an image under the object's vector art. The image was
rendered over nothing and placed with Normal blending, so a Screen glow
or a Multiply shadow came out as Normal in the PDF. Each image is now
composited with its effects' blend mode, one image per mode when an
object's shadows and glows use several.

bflatasticandClaude Opus 5.5 b9b880a5de Review fixes for #765: the glow outside a shape keeps the edge's colour
The output multiplied the glow's colour by its opacity a second time, so outside the shape (where
the glow sets the opacity) it darkened as it faded and showed as a grey rim over a light
background. The test now checks that the fading glow keeps the edge's colour.

Clippy 1.99.0 added `chunks_exact_to_as_chunks`, which fails `cargo xtask ci`
at its clippy step. Eight uses of `chunks_exact(_mut)` with a constant size now
use `as_chunks(_mut)` (stable since 1.88, within the 1.95 minimum): four in
crates/affinity, three in crates/effects and crates/engine tests, and two in
xtask's sha256. docs/development.md says the gate targets the current stable.

bflatasticandClaude Opus 5.5 8255d606ae M8.14: Type and symbols in perspective are really projected and stay editable; attachments survive copies
Type and symbol instances attached to a plane keep their art and carry a projection
(Node.perspective.projection, append-only); the canvas and every export draw their outlines
through it (reshape/bake), so they are foreshortened and stay type and symbol instances. Bounds,
hit testing and transforms follow the projection. Object › Perspective › Edit Text
(perspective.editText, or double-clicking with the Perspective Selection tool) shows the type flat
where it is drawn in isolation mode; exiting isolation projects it again. Release with
Perspective keeps their look. Copies, pastes, duplicates and Selection-tool moves keep the
attachment (the art moves as dragged). Flare, spiral and polar grid draw on the active plane, and
so do the click-to-size shape dialogs (perspective.draw `at`: sizes in plane units).

bflatasticandClaude Opus 5.5 04fa49413c M8.16: Envelopes bend images, symbols, gradients, patterns and appearance; warps keep their frame
- Images distort as a raster mesh warp: cut by Fidelity into triangles,
  each a clipped image under the affine map of its corners (pieces overlap
  slightly, no seams; the renderer paints them without clip layers; SVG
  writes the pixels once and <use>s them).
- Symbol instances distort as their symbol's art (the renderer's cache
  follows edits to the symbol).
- Distort Appearance bakes strokes (filled outlines) and geometry effects
  before bending; Distort Linear Gradients bends linear gradients; Distort
  Pattern Fills bends the tiles. Opacity masks of the content bend too.
- Bug fix: a rotated, sheared or reflected warp envelope re-warped along
  the page axes. Envelopes now keep their own frame (append-only model
  field), so the warp turns with the art; move and scale keep it square.
- Live evaluation shares one set of hooks (vectorcraft_doc::live::Hooks,
  vectorcraft_effects::{expand_live, expanded_live_group,
  expand_live_deep}) between the canvas, Expand and every exporter.

Every exporter (SVG, PDF, EPS, EMF/WMF, DXF) evaluated live objects with no
text outliner, so type inside an envelope was written undistorted. They now
share vectorcraft_effects::expand_live_deep, which outlines type per run in
each run's paint, as the canvas now does too (it used the first run's paint
for the whole line).

bflatasticandClaude Opus 5.5 9920156bb6 Fix #122: colour adjustment live effects (Effect > Color Adjustments)
The issue asked for non-destructive colour adjustments in the Effect menu
and the Appearance panel that work on vector paints, live type and
embedded images. Only the destructive Edit Colors commands existed, and
the live-effect pipeline only knew geometry and raster effects.

Effect > Color Adjustments adds six effects (adjust.*). They recolour,
in stack order, everything an object paints with: fills and strokes
(gradient stops too), type, gradient meshes, embedded images and a
group's members, each colour keeping its model. The Edit Colors walk over
an object's colours moved to vectorcraft_doc::recolor so the commands
and the live effects share it. The renderer draws adjusted art through
its object-effect path (recoloured images cached within a memory
budget), exports bake the adjusted colours (images as recoloured
copies), and Expand Appearance makes them permanent. The effect dialog
shows sliders, a channel menu and a draggable Curves graph, all previewed
live as one undo step.

bflatasticandClaude Opus 5.5 811ad1efd8 Fix #121: sandboxed WebAssembly plug-ins: object filters and live effects
VectorCraft had an Additional Plug-ins Folder preference but nothing loaded from it. Port
PhotoCraft's wasmi plug-in host (same sandbox, manifest and parameter schema) as the new
vectorcraft-plugins crate (L2), extended for vector documents:

- Object filters read the selected paths and compound paths as JSON (native PathData and
  Paint forms: geometry, fills, strokes, gradients, opacity) and return the objects to keep,
  change, add or delete; the output is validated in full and applied as one undo step
  (plugin.run). A failing plug-in leaves the document untouched.
- Live-effect plug-ins are geometry effects in the appearance stack (effect id
  plugin.<id>), re-evaluated (and cached) when the object or parameters change, editable,
  exported and baked by Expand Appearance; a missing plug-in leaves the geometry as is.
- plugin.list / info / run / install / remove / reload; the preference folder installs
  every *.wasm at startup and when it changes; File > Open of a .wasm installs it (web).
- Object > Plug-ins and Effect > Plug-ins menus with dialogs generated from the parameter
  schema (live preview), the Appearance panel's fx menu, docs/plugins.md, an original
  example plug-in (Desaturate, a Rust crate outside the workspace) and fuzzing of the
  plug-in boundary (engine/tests/plugin_fuzz.rs).

Tool plug-ins and paint-changing live effects are left for later (docs/plugins.md).

bflatasticandClaude Opus 5.5 e967c31be6 M4.58: raster effects in PDF on every kind of object
PDF export now renders the shadows, glows, blurs and feathers of groups,
layers, type, images, symbol instances, live objects and single fills and
strokes (and those inside opacity masks, symbol definitions and pattern
tiles) as images at the document raster effects resolution, instead of
leaving them out with a warning. Shadows and outer glows go under the
untouched vector art; a path whose fills or strokes carry effects is
written as one piece per fill and stroke. Expand Appearance shares the
image helpers (moved to rasterfx.rs); effect images now cover what the
renderer paints (members' shadows included).

General sets them (one undo step) and is the units new documents start

indents, Pattern Options, dialog distances (Move, shape sizes, path

dialogs), New Document and the canvas measurement labels (smart-guide
sizes, moves, the Measure tool, the Live Corners radius) all follow it,
live. Units > Type drives font size, leading and baseline shift; Units >
Stroke also reaches the Appearance panel and the Magic Wand weight
tolerance. Typed units ("5 mm", "12 pt") work in any field; all ten
units are choices; length preferences show in their unit and accept a
unit; offset/simplify/grid/type-size params read typed units. Typed text
starting with a multi-byte character no longer panics the parser.

Brandon ThomasandClaude Opus 5.5 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.

bflatasticandClaude Opus 5.5 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.

Double-clicking a width point opens Width Point Edit (Side 1, Side 2, Total Width, a link

as one undo step; Alt-dragging a point's centre copies it (`stroke.widthPoint.copy`); dropping a
point onto another makes a discontinuous point (two points at the same t), and the stroke's
width steps there. `stroke.widthPoint.set` takes `adjustAdjoining`, keeps a discontinuous point
when only its widths change, and `stroke.widthPoint.remove` takes `indices`. Flipping a profile
along the path swaps the sides of its steps; `document.inspect` reports `widthPoints`.
