Each rib of a dashed stroke with a width profile looked up to 256 points
either way along the path, asking the profile at every step, and reached
as wide as the stroke gets anywhere past that. A sliding maximum over the
points' precomputed cover now gives every rib's reach in time in
proportion to the points, with no bound and no fallback to the widest
width (review on #6093).
With a width profile, every slice of a stroke gradient (along or across)
reached as far as the stroke is wide anywhere. Where the stroke crosses
or runs close by itself, the later, narrower part painted a square of
its colour over the wider part beside it, clipped only to the whole
outline. Each rib now reaches as far as the stroke is wide there and on
its way to the next points (each side of a profile stays between its
widths at a span's points); for a dashed stroke, as wide as it gets
within a cap's reach, since caps and dots reach along the path.
The baked Transform and Free Distort tests now compare each placed
gradient's start, end, aspect and focal point with the expected values
within a tolerance, and the Transform test adds a turn with a scale.
A gradient placed with the Gradient tool stayed where it was when the
object's Transform or Free Distort effect moved, turned or scaled the
outline, so the shape slid across its own gradient.
The Transform effect now maps placed gradients by its own transform,
and each of its copies takes them as many times as it takes the
transform. Under Free Distort, each path's placed gradients move and
scale from the path's bounds before the effect to its bounds after it.
This change does not alter gradients fitted to the object.
The canvas, Expand Appearance and export, Pathfinder and compound
shapes, groups, a fill's or stroke's own effects, and Object › Expand
of a gradient fill apply the same rule. In a group, the own fills and
strokes of the group, of the groups inside it and of a symbol's art
follow it too, and images and symbol instances that a group's
Transform effect moves take the placed gradients of their own fills
and strokes along. A group whose path keeps its shape because the
effect would pass the geometry budget keeps its own gradients in
place.
This changes how existing documents draw: a gradient placed on a path,
or on an image's or symbol instance's own fill, inside a group with a
Transform effect now moves with it. Before, only the gradients of type
moved (#2214).
How gradients follow each effect is VectorCraft's own rule. The
Distort & Transform help page describes what the effects do to the
object:

An envelope mapped type from its laid-out box: ascent to descent for
point type, the frame for area type. The distorted glyphs then filled
less of the envelope than other art does, with room above the capitals
and below the baseline.
The envelope now maps type from the bounds of its glyph outlines,
underlines and strikethroughs when the type is on its own, in groups
and layers, or used as a clipping path. Inline graphics count by their
boxes. Rotated type and type in perspective map from their outlines as
they are drawn. Make with Mesh,
Make with Top Object and Reset with Mesh without Maintain Shape use
those bounds. Type that draws nothing keeps its laid-out box, and so
does type inside any other object, such as a blend, a repeat or a
symbol instance. Shrink Text to Fit type is measured as it is laid out
on the page.
vectorcraft-text's envelope_ink measures the type, and
register_envelope_ink registers it with the document crate. The engine
session, Renderer::new, live evaluation in vectorcraft-effects and the
.ai reader register it. The document crate keeps the measured boxes per
thread, by object and by a hash of the content, and measures again when
the type, the fonts, the hyphenation exceptions or the transform's
scale or rotation change.
This is VectorCraft's own rule. Envelopes of type made in VectorCraft
and in saved files map from the glyph outline bounds instead of the
type's laid-out box, so they redraw differently.
The panel opens from Window › 3D and Materials (window.panel {panel:
"threeD"}). Its object types Plane, Extrude, Revolve and Inflate apply
Rotate, Extrude & Bevel, Revolve or Inflate to each selected object
without a 3D effect, and change the 3D effect of each other selected
object in place, all as one undo step. Below them are the effect
dialog's Object, Rotation and Lighting tabs with the same controls.
A changed setting goes to every selected 3D effect that takes it, as
one undo step; a drag previews and records one step on release, and a
change of selection during a drag commits it first, and so does closing
or hiding the panel. A setting the
selected effects hold with different values shows its default with its
reset dot filled. A light list edit reaches only the objects whose list
matches the first object's.
effect.setParams takes threeDType (plane, extrude, revolve, inflate):
the settings both effects take keep their values, rotation angles wrap
into -180..180 outside Revolve, and the rest start at the new effect's
defaults. Another value, or a non-3D effect at index, is refused; the
type an effect already has, with nothing else to change, records no
undo step.
Materials, shadows and ray-traced rendering are not part of this.

Fixes#3672
With ribs only at the path's corners (an Along gradient), the ribs that reach
across an arrowhead stopped at the last corner inside its reach, so the slice
narrowed from the head's tip towards the next corner and left the corners of
a Triangle head's base outside every slice. Where each arrowhead's reach ends
now gets a rib of its own.
The width between two width points was a straight line, so a variable-width
stroke turned a corner at every width point.
- Each side of a width profile now follows a monotone cubic (Fritsch-Carlson)
through its points: no kink at a point, flat at a point wider or narrower
than both neighbours, never past either point of a span. Points on one line
stay on it and two-point tapers are unchanged; stacked points still step.
- widest() counts each span's wider left and wider right, since the two sides
needn't peak together.
- The outliner samples straight runs between width points closely enough to
follow the curve to the drawing tolerance (at most 64 samples per span and
4,096 per piece); straight spans get none.
- Tests that expected straight-line widths now expect the curve. The stroke
gradient coverage test uses Teardrop instead of Wave until #5964 is fixed.
A 3D effect on a group or layer builds a solid from every path,
compound path and type in it, all turned about one shared axis, as the
public docs describe for groups. Fixes#4506.
A path whose fills and strokes stack (a fill and a stroke, several of
either, an even-odd fill, or a partly transparent or blended one) drew
its Transform effect's copies as one path, so every copy's stroke lay on
top of every copy's fill. It now draws each copy as an object of its own
above the one before, as Expand Appearance makes them.
Fixes#5920
A path or compound path whose Transform effect made copies expanded to
one compound path of every copy. It now expands to a group of one object
per copy, each painted as the path, as gradient copies already did; a
second Transform effect's copies nest in a group per copy of the first.
Drawing is unchanged.

A dashed stroke of a path with more than 1,024 path elements was outlined
whole in every frame after an edit. It is now outlined in and around the
view like a solid stroke. dash_kept runs the pattern along every segment
and keeps only the dashes and dots on the segments near the view, so they
sit where dashing the whole path puts them and the pixels are the same.
A pattern too fine to draw is still drawn solid, and that solid stroke is
cropped too.
At 1600 x 1200 the frame after one anchor moves takes 14 ms instead of
102 ms on a filled closed path of 50,000 anchors with 6 pt dashes and
4 pt gaps. anchor_bench now includes that document.
Add Anchor Points builds the new anchor list in one pass, Swatch Library add looks names up in sets, full_documents dedups placed keys with a set, width profile lookups and mark insertion use binary search, and the symbolism tools cap and thin the previews of a long drag as Liquify does.
With Envelope Options > Distort Appearance on, a path whose Transform
effect has Scale Strokes & Effects or Transform Patterns on, or copies it
with a gradient, was baked with the effect as geometry only: every copy
kept the original's stroke weight, dashes and pattern placement before
the envelope bent it. bake_appearance now makes such a path into the
per-copy art that drawing, export and Expand Appearance already use, and
bakes each copy's strokes into filled outlines from there.
The geometry effects after a fill's or stroke's own Transform effect with
Scale Strokes & Effects or Transform Patterns now take the bounds of the
transformed path and all its copies as their reference box, as an
object's own effects do. A later Rotate turns the copies about their
combined center instead of turning each copy about its own, and a later
Offset Path or plain Transform applies to the paths themselves. Each copy
keeps its own scaled distances.
Part of #885
transform_item_leaf now holds back the leaf's geometry for each plain or transformed piece that follows a transformed fill or stroke, so the copies of an earlier item no longer use up the budget that a later fill or stroke still needs. The nested pass over a transformed piece keeps to the same reduced limit.
Each fill or stroke without such a Transform effect is drawn on the object's geometry again, so its cost now counts toward the budget that limits the Transform effect's copies. The object's own geometry is no longer counted a second time next to the pieces that replace it. The Transform effect options entry in docs/target-app-parity.md links the current help pages.
Part of #885
A Transform effect in a fill's or stroke's own effect list now applies its
Scale Strokes & Effects and Transform Patterns options as the same effect on
the object does: the stroke's weight and dashes, the distances of the fill's
or stroke's later effects and its pattern follow the transformation, each
copy once more than the last, and with Transform Objects off the geometry
stays and the options apply once. The fill or stroke becomes an object of
its own in the art the canvas, export and Expand Appearance draw, and Use
Preview Bounds measures that art too (also for the object-level options).
Part of #885
Effect › Color Effects › Duotone… (addon.color.duotone, also in Object ›
Plug-ins › Color Effects) prints the grey-equivalent tone of each colour
with one to four inks, each with its own tone curve. It is a colour
adjustment like the add-on's others, so it stacks with them and works as
a filter through addon.color.filter.
- One tone of a swatch the document has gives a tint of that swatch,
linked, so a spot tone separates onto its plate; several tones give
the CMYK mix of their tints (the inks overprint, so they multiply).
- Colour adjustments now map paints with their swatch links
(ColorMap::apply_link); the existing adjustments behave as before.
- Skip Objects with Spot Colors leaves spot-linked colours as they are.
- The dialog has a row per tone and the picked tone's curve (the Curves
graph, reused), its points and Reset to Linear / Inverse.
Print Ink Fixes (addon.color.printFixes, Object › Plug-ins › Color
Effects › Print Ink Fixes…) scales CMYK colours over a total ink limit
down to it, removes white overprint and sets black overprint (Overprint
Black's logic) in a CMYK document, as one undo step, and reports what
changed. RGB documents are refused.
The panel opens both under Inks.
Deferred: an opaque undercoat, tones for type only, extra gradient stops
for smoother tints, curve flip and all-100 % buttons.
Effect › Color Effects › Vector Halftone… (addon.color.halftone, also in
Object › Plug-ins › Color Effects) draws its object as the halftone dots
Object › Vector Halftone makes, live: mono (one dot colour, or each dot in
the art's colour under it) or CMYK screens, the five dot shapes,
frequency, angle, invert and clip to the art's outline.
- The screens, dots and caps move to vectorcraft_effects::addons::halftone,
shared by the command (its behaviour and tests unchanged) and the effect.
- The renderer samples the art (vectorcraft_render::addons::halftone) and
keeps the dots by the object's content and what it reads from the
document, so unchanged art isn't sampled again; past 100000 cells per
screen the object draws as it is.
- Expand Appearance turns the object into its dots, and the SVG, PDF, EPS
and AI exporters write them as paths.
- Its dialog reuses the command's fields, without Keep Original.
Deferred: stochastic and radial patterns, a dot-gain curve, per-screen
separation settings, type or symbols as dots.
A built-in add-on in Effect › Color Effects and Object › Plug-ins › Color Effects:
- Exposure (stops of linear light, offset and gamma), Desaturate and
Invert Colors as live colour adjustments, evaluated in stack order with
those of Effect › Color Adjustments.
- addon.color.filter applies any colour adjustment to the colours
themselves, through the Edit Colors pass, as one undo step.
- A panel picks an adjustment and its values, then adds it as a live
effect or applies it as a filter.
The add-on lives in its own modules (effects, engine and ui-egui addons
folders) and leaves the existing effects, commands and menus as they
were.
Follow-up to #4345 / #4145 per maintainer guidance from @bflatastic.
- In `crates/effects/src/geometry.rs` & `crates/effects/src/reshape.rs`:
- Implements `optimize_geometry_effects`: reorders pure-translation Transform effects
with copies after a terminal round-join Offset Path effect when the effective style is safe
(NonZero fill and no stroke).
- Offsetting a union equals the union of offsets for round (Minkowski) offsets; moving
pure-translation copies after the terminal offset evaluates Offset Path once on the base
geometry rather than over dozens of multiplied copies, turning O(copies * segments) planar
sweep explosion into a single fast offset plus lightweight affine copies.
- Safely commutes across multiple consecutive pure-translation Transform effects.
- Preserves exact visual geometry by leaving miter, bevel, EvenOdd, stroked, or non-terminal
effect stacks in their original order.
- Added comprehensive unit and regression tests in `crates/effects/src/tests.rs`.
- Added contributor entry in `contributors/people.toml`.
