Patch and triangle mesh shadings of more than 4,096 patches, and strokes
painted with a mesh shading, came in as a flat grey. Illustrator writes
meshes of up to 14,355 patches, and writes a freeform gradient on a
stroke as a stroke painted with a type 7 shading.
- MAX_PATCHES is 16,384, as in the .ai editing-data reader.
- A stroke painted with a mesh shading is the meshes clipped to the area
the stroke paints (stroke_outline: width, caps, joins, miter limit and
dashes, built in the path's space and then transformed); draw_meshes
always clips a stroke's meshes.
Two follow-ups to the empty-page fallback:
- A page counts as empty only when nothing on it was skipped: its only
notes are the page's own (art off the artboards, art past the page). A
page whose only content couldn't be read, such as an image that can't
be decoded, keeps its notes and goes through the usual check against
the editing data, instead of being replaced by it unchecked.
- With textAs: outlines, the document read from the editing data alone
has its type outlined. The usual path takes outlines from the page,
but an empty page (or a text-only placeholder, #1387) has none to give.
A mesh in the editing data that the reader couldn't read made the whole
file come in as its page or PDF part, without its layers. Three cases
were rejected that files write routinely:
- A mesh starts grey, and `/CS` is written only where the colour space
changes, before the corner it applies to, even within a patch. Meshes
with no `/CS`, or one that changed between corners, were unread.
- Named colours (`[c m y k /DeviceCMYK (name) /Process]` or `/Spot`) and
`/NChannel` inks: each corner gives the tint, 1 being the full colour.
- Grids over 64 patches a side or 4,096 patches (files have 97 x 72).
Each corner now takes the colour space last set before it; named
colours paint at their tint and inks overprint at theirs; the limits
are 128 a side and 16,384 patches.
In effect dialogs (like Color Halftone), length fields with defined bounds
(e.g. Max Radius 4..127 pt) were previously checked only after num_field
returned, leaving the field's temporary buffer holding the un-clamped string
(e.g. '0.5 px'). Subsequently entering invalid text caused the field to
fall back to that sub-minimum buffer.
- Added num_field_within to pass effect parameter bounds directly to unit_field.
- When committed, clamp the parsed value within bounds and update the field
buffer to the formatted clamped value so the UI reflects what is applied.
- When invalid text is committed, clear the invalid buffer and trigger a
one-frame border highlight so invalid input is rejected visibly.
normalize_bez ran the sweep without the catch_unwind guard that Sweep::new has,
so an outline_stroke width of 1e200 or more with a round join panicked inside
linesweeper (Left == Ish). The panic is now a Degenerate error and the art is
left unchanged. Adds hostile-number tests for the pathops edit, stroke and
offset functions.
A built-in add-on under Object › Plug-ins › Smart Pen:
- The Smart Pen Tool draws and edits Bézier paths without switching
tools: a click adds the next segment straight or curved (a panel
toggle; Tab flips the segment being placed or the last one), a drag
makes a smooth point (Alt breaks the handle, Shift snaps to 45°, Space
moves the point), a curve after a straight segment joins it tangent.
- On existing paths it selects and moves points, removes a point keeping
the shape (Alt-click), toggles smooth/corner (double-click), drags
handles, reshapes a segment by dragging it and inserts a point on it
(Alt-click); it closes, continues and joins open paths.
- The Smart Pen panel: next segment straight or curved, remove points
keeping shape, make smooth, make corner, retract handles, close or
join.
The tool stays out of both toolbars as shipped; the All Tools drawer
lists it under the add-on's heading. Commands are addon.pen.*; the
existing Pen tool, commands and menus are unchanged.
A built-in add-on under Object › Plug-ins › Path Precision Tools:
- Anchor Eraser Brush: painting over selected paths removes the anchors
under the brush that the outline can do without within a tolerance,
refitting the handles beside them (Alt ignores the tolerance, Cmd/Ctrl
deletes without refitting, pen pressure can scale the brush); one undo
step per stroke.
- Extend Path tool: dragging an end of an open path carries it on
straight, by stretching its last curve or along the circle it curves
on, or shortens it back along itself.
- Measure & Inspect tool: drag to measure distance and angle; hover a
path to read segment and path length, area, curvature, tangent and
anchor angles and handles, in the document's units.
- Anchor Inspector panel: the selected anchor's position and handles as
numbers, with Make Smooth (auto-smooth rule), Make Corner, Equalize
Handles, Remove Points Keep Shape, Add Points and three ways to close.
- Add Points at Crossings and Split at Crossings.
The tools stay out of both toolbars as shipped; the All Tools drawer
lists them under the add-on's heading. Commands are addon.pathtools.*;
the existing commands, tools and menus are unchanged.
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.
A built-in add-on under Object › Plug-ins › Artwork Cleanup:
- Simplify Anchors (Keep Shape) removes anchors while the outline stays
within a tolerance, optionally keeping sharp corners.
- Document Health Check finds and fixes 16 kinds of problems in the
selection or the document (stray points, duplicate and collinear
anchors, tiny handles, nearly closed paths, needless groups, compound
paths and clipping groups, unpainted and invisible objects, duplicate
objects, art off every artboard, empty artboards…), with Show, Fix
Selected and Fix All, each fix one undo step.
- Deep Ungroup and Rejoin Path Pieces.
The add-on lives in its own modules (pathops, engine and ui-egui
addons folders) and leaves the existing commands, tools and menus as
they were.
UPDATE_APP (native builds; craft-update is a native-only dependency) carries our 128 px icon and accent (#e8573f, its colour in ArtCraft Launcher). The updater, the self-update
helper and craft-update's startup prompt all get them through crate::UPDATE_APP; the
prompt draws the icon, the accent and "by ArtCraft" (craft-update's default developer).
craft-update is pinned to storytold/craft-libs main at 1065653e7 (#434).
Clippy fixes for Rust 1.99 in untouched code (same logic):
- crates/svg/src/import/fx.rs
- crates/tools/src/text/tool.rs
A placed (linked) file is put where its matrix takes the canvas point of
art space's origin (the centre of %AI3_TemplateBox). In many files the
matrix takes the corner of the box the file is written with instead, so
the image landed far off its artboard, the layers differed from the
page, and the file came in as its PDF part.
The reader keeps that second placement for each placed file where the
two differ. When the layers don't draw as the page, they are compared
again with those files at their box's corner, and used if that draws
as the page. Files whose layers already match keep their placement.
A placed (linked) file written as an object's editable copy, on %_
lines after its drawn look, has its %AI5_BeginPlace and %AI5_EndPlace
markers on those lines too. The lexer dropped comments after %_ that
don't start a section, so the placed file never began, the ~ that ends
it was an operator the reader didn't know, and the whole file came in
as its PDF part. The lexer now returns those two markers from %_ lines,
and the preview reader skips the %_ its header line starts with.
The Help > Check for Updates… item, the update window and the Image Trace
progress labels had no ja row and drew English. Wording follows the
PhotoCraft ja catalog for the update strings.

PDF export (and the PDF-compatible .ai it writes) cut each gradient mesh
patch into 8 x 8 flat-coloured quads. Viewers showed colour bands and
hairline seams between them, and files with many meshes became very
large and slow to write.
An opaque mesh is now written as one Type 6 (Coons patch) shading
(ISO 32000-1, 8.7.4.5.7) filling its outline, through the PDF writer's
MeshGradient: each patch blends its corner colours bilinearly, as the
canvas draws it. Colours go through page_color as other fills do, and a
mesh mixing RGB with other models goes through RGB. A mesh with
see-through points, an invalid one, or one past the coordinate range
keeps the quads.
A PDF-compatible .ai whose PDF part's pages are cropped to its art (each
page the box of all the art, the editing data's bounding box) rather
than to its artboards came in as that PDF part: the editing data's
artboard wasn't the page's size, so its layers were refused. With
several artboards every page held all the art, so the document had a
copy of everything per page.
When the artboard isn't the page's size but the editing data's bounding
box is, the layers are compared with the page on that box and keep
their artboards. The comparison of their art with the page still
decides whether they are used.
With Preferences > Performance > Real-time Drawing and Editing off, tool
previews are deferred to the release, so a guide dragged out of a ruler
(guide.add) or moved with a selection tool (guide.move) showed only its
position label until the button was released. Guide previews now always
apply as the guide is dragged: the guide is all such a drag shows.
#4646's units and guides lost on reopen don't reproduce for a native
file: a new millimetre document's ruler guides and units survive Save,
Close and Open in .vectorcraft, PDF, .ai and EPS (new regression test,
and live in the app with Background Save). An SVG saved without Preserve
Editing reopens in pixels with no guides, as the reporter saw.
A pattern fill was written to EMF as every tile's art, each tile in a clip
of its own, with the brush made again for each part: a rotated two-colour
stripe fill of a 360 x 260 pt rectangle took 473 fills, 246 clips and
122 KB.
When the tiles can't overlap (a grid or brick tiling whose art stays in its
tile), each tile's clip is left out where what it clips lies inside it
already (a convex clip holding every control point of the fills), and the
n-th fill of every tile becomes one path. The picture is the same: the
tiles don't overlap, and the fill's own clip still trims them. That fill
is now 2 fills and 1 clip, 61 KB; unrotated, 99 KB becomes 33 KB.
Tiles that overlap, hex tilings, and tiles holding strokes, images or
clips that cut are written as before, their parts off the page left out.

A layered .ai or Illustrator EPS whose editing data (embedded rasters,
mostly) unpacks past 512 MiB opened as its PDF part or printed page, in
one layer, with "it decompresses to more than 512 MB" (#4628 on 0.17.0
hit the older 256 MiB limit the same way).
The limit is now an eighth of installed memory, from 512 MiB (what every
64-bit build read before) to 2 GiB: 1 GiB on an 8 GiB machine, 2 GiB on
16 GiB or more. Reading takes about as much memory again as the data
(1.1 GB of data with 24 embedded 4096 x 4096 images peaked 1.1 GB above
the start), so the ceiling keeps a small file that unpacks without end
from taking a large machine's memory. 32-bit and web builds keep 256 MiB.
vectorcraft_render::installed_memory exposes the reading the image cache
already sizes itself from.
