VectorCraft does not run scripts written for the reference app, and
File › Scripts held only the disabled Other Script…. File › Scripts ›
Check Script… picks a .jsx, .jsxinc or .jsxbin file, reads it without
running any of it, and shows a report: what the script needs (the
script language's own objects, the document model, files, menu
commands, dialogs, or features only the reference app has), what it
would do outside the document, the menu-command strings it passes, the
document-model member chains and type names it uses, its directives,
the files it includes, and the problems that would stop it loading.
Copy Report copies the report as JSON. File › Open and drag-and-drop
show the report for those files too.
- vectorcraft-scriptcheck, a new Standalone crate with no
dependencies, holds the checker: a lexer for ECMAScript 3 with E4X
literals and the #name and //@name directive lines, and an analysis
of the tokens that follows variables, function scopes and the files
a script includes. It never recurses: open brackets, the levels of
an XML literal and the function bodies being read are kept on stacks
capped at 4,096. It reads at most 8 MiB of a file and 32 MiB with the
included files, follows 64 included files 16 deep, looks up at most
1,024 paths for them, keeps 1,000 entries in a list, tracks 1,000
variables holding member chains and 1,000 holding File objects, and
cuts echoed text to 120 characters. A compiled script is reported as
compiled and isn't read.
- script.check (engine, a query) takes path, data or dataBase64. With a
path and includes: true, it reads the files the #include lines name
from inside the script's folder, through the automation read root,
and when the script or one of those files assigns a member chain or a
File object to a variable, the check treats the variable as holding
it in every file. It doesn't follow absolute names, names, folders or
links that lead out of the folder, names or folders longer than 4,096
bytes, or JSINCLUDE, and it reads only regular files.
- ui.checkScript shows the report (dialog scriptCheck). File › Open
lists Scripts (.jsx, .jsxinc, .jsxbin) and sends a script's path to
script.check, which reads at most 8 MiB of it.
The language rules come from ECMA-262 3rd edition and ECMA-357 2nd
edition. The directive, platform and document-model root names come
from the public JavaScript Tools Guide and scripting guide pages that
catalog.rs cites by URL, and executeMenuCommand, doScript, loadAction,
unloadAction and selectTool come from the public forum posts cited
there; only names are used. Every script in the tests is written from
scratch with invented names.

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.
A /ForeignObject (non-native art: the content of a placed PDF, which
Illustrator shows but doesn't edit) was left out with a note. The
letterhead of #861 keeps its fan of swooshes that way: a radial gradient
in a 3-point PDF, scaled 271 times and clipped by the swoosh paths, so
the page lost its main graphic.
The reader now decodes the object's ASCII85 /Data, has the PDF importer
read the PDF, and fits its art to the object's box as a group named
"Non-native art": /Bounds measured from /Origin with y down, then
/RTransform, which lands exactly on the clipping paths around both
objects of that file; the PDF's content is kept in its own y-up
coordinates, so it is flipped into the box. Ids are the document's and
the PDF's swatches stay unlinked; its images join the document by
content key. A PDF that can't be read is left out with a note, as
before.
The EPS crate now uses the PDF crate (same layer; allowed in the layer
check like render and metafile).

Read only the indexed PNG thumbnail observed in version-12 Affinity containers. Bound and validate the PNG before decoding, warn about omitted native content, clear the source save target, and reject auxiliary imports that cannot display that warning. Add malformed-input, lifecycle, property and optional native-oracle tests plus a fuzz target. Editable native layers and Affinity export remain unsupported.
Discord feedback: "EPS files are always rasterized: they open as bitmaps, in
other programs as vectors". Every EPS saved by Illustrator 2026 fell back to
its TIFF preview (`gcheck` was unknown), and cairo/Inkscape files stopped at
their first image (`status`), dropped masked images (ImageType 3) and failed
on mesh gradients; the warning didn't say where the program failed.
Fallback never silent:
- The warning names the PostScript error, the operator that raised it and
the named procedures it ran in, innermost first ("a PostScript error
(typecheck in `add`), in `inner` in `outer`"); errors caught by `stopped`
aren't reported. It reaches the status bar, document.open, app.open and
file.open (which now return document.open's result, so MCP's open_file over
the control channel gets it), and `vectorcraft-cli info` ("warnings").
- A file whose PostScript can't be read opens as its TIFF preview, else its
Windows metafile preview (as vectors, scaled to the bounding box), else its
EPSI bitmap. es @msg rows for the new messages.
Interpreter:
- Operators programs probe or use: gcheck/scheck, rootfont,
currentcolorrendering, currenthsbcolor, status, token, read,
bytesavailable, fileposition/setfileposition, resetfile, write*, pdfmark
(marks dropped, as Ghostscript does), execform, nulldevice, strokepath,
pathforall, user paths (ufill/ueofill/ustroke/uappend/upath/setbbox, the
encoded form too), setcachedevice2, findcolorrendering, cache, device and
VM queries, revision; (%stdout) (w) file gives a sink.
- `//name` is replaced by its value when read, inside procedures too.
- Tiling patterns become pattern swatches (their PaintProc drawn in pattern
space, one cell; uncoloured ones in the colour under them; makepattern
copies share one swatch); nested patterns stop at 8 levels.
- Type 3 fonts draw their glyphs (BuildGlyph/BuildChar, widths from
setcachedevice/setcharwidth) as outlines grouped per string, spaced by
ashow/widthshow/awidthshow/xshow/yshow/xyshow/kshow; glyphshow and
stringwidth/cshow use them.
- Shadings of types 1 and 4-7 become gradient meshes (data from arrays,
strings or files, packed or not, flags sharing edges), as fills through a
shading pattern too; sampled functions (type 0) are evaluated;
GradientMesh::coons/triangle are shared with PDF import.
- ImageType 3 masked images, interleaved by sample, by row or in separate
sources; ReusableStreamDecode reads its data when made; Flate/LZW PNG and
TIFF predictors.
- Bounded: DeviceN at 32 inks, sampled functions at 2^24 samples and 32
outputs, 4096 patches a shading, strokepath ignores dashes finer than 1e5
pieces, Type 3 glyphs nest 8 deep (a glyph that shows itself overflowed the
stack before the limit), 64-bit index maths for 32-bit targets.
Tests: a synthetic program per generator (cairo/Inkscape, its Type 3 fonts,
matplotlib, CorelDRAW, Affinity, LibreOffice, Ghostscript eps2write,
Illustrator procsets), meshes and function shadings, masked images, fault
messages, probing operators, metafile/EPSI previews, `//name`, user paths,
hostile patterns/glyphs/shadings (run against main, 12 of the 14 generator
and feature tests fail; CorelDRAW- and LibreOffice-style programs already
read there). The import fuzz vocabulary covers the new operators. Checked
against real files made here with Inkscape 1.4 (cairo) and Illustrator 2026
(its own format and the CS-to-CC compatibility formats; all fell back or
stopped early on main and open as vectors now; its Illustrator 8 format
needs the next commit); those files aren't committed.

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).

egui 0.36 needs rustc 1.95 (hayro and krilla 1.92), so the declared 1.90 let
cargo fail on dependency versions instead of naming the toolchain. Clippy 1.95
also flagged four collapsible matches that newer clippy no longer does; each is
rewritten without changing behaviour.

document.export {format: "tiff"} writes baseline TIFF through the raster
export path (resolution, background, anti-aliasing, artboard ranges):
colorModel rgb (transparency as unassociated alpha), cmyk (ink amounts,
CMYK colours keep their inks) or gray, lzw (weezl), byteOrder little (II)
or big (MM), embedIcc, and the resolution tags. Export As offers it with
the tiffOptions dialog; TIFF moves from read-only to read and write.
The TIFF writer is shared: EPS previews now use it (and its PackBits)
instead of their own copy, so eps depends on render (layers allow it).

New crates/metafile (L3, pure Rust): hand-written EMF and WMF writers over
one shared document walk. EMF keeps Bezier paths, solid brushes, geometric
pens (width, caps, joins, miter limit, user-style dashes), clipping masks as
path clips, images (StretchDIBits, or AlphaBlend with transparency) placed by
a world transform, type as outlines; gradients become images clipped to their
shape and pattern fills their tiles clipped to it. The header's frame is the
artboard in 0.01 mm on a 100 px/mm reference device. WMF flattens curves into
polygons in 16-bit units behind a placeable header (with its checksum),
numbers objects as players do, and reports what it leaves out (clipping,
transparency, gradients, rotated images).
document.export {format: emf|wmf} (and serialize, export) writes one artboard,
or one file per artboard with useArtboards (false: the art's bounds); raster
effects are rendered to images first, as for PDF. Export As lists EMF and WMF.

New crates/eps (L3): a hand-written EPS writer. A DSC header with
%%BoundingBox and %%HiResBoundingBox (y up from the origin), %%LanguageLevel
and spot colours; paths filled and stroked with caps, joins, miter limits
and dashes (strokes a plain line can't draw as filled outlines, brushes as
their art), clipping groups, linear and radial gradients as smooth
shadings at Level 3 and stepped fills at Level 2 or with compatible
gradient printing, patterns as tiles, freeform gradients and placed images
as images (Flate with masked transparent pixels at Level 3, run-length at
Level 2), type as glyph outlines, spot colours as Separation spaces and
overprints when preserved; RGB written as CMYK on request. A TIFF preview
(1-bit or colour, transparent or opaque) behind the binary header, a PNG
thumbnail and the native document in comments (eps::native and
eps::thumbnail read them back for a later import).
document.export {format: eps} and document.exportEps: transparency is
flattened first with a flattener preset (built-in or saved) and options;
the visible art's bounds, or with useArtboards one file per artboard named
{stem}_{artboard}.eps. Export As lists EPS, then EPS Options
(ui.epsOptionsDialog for agents, remembered between exports).

New crates/cad (L3): a hand-written ASCII DXF writer. Layers become DXF
layers (hidden: off, locked, non-printing: not plotted), straight paths
LWPOLYLINE (POLYLINE before R14), curves cubic SPLINEs through every
anchor, fills solid HATCHes (outlines in R12), strokes lines with a
lineweight and a linetype per dash pattern, type TEXT or glyph outlines,
placed images IMAGE entities linked to PNG or JPEG files. Units and
scale ($INSUNITS), scaled lineweights, 8/16/256 indexed or true colour
(420), transparency (440), Preserve Appearance / Maximize Editability,
Alter Paths for Appearance, Outline Text.
document.export {format: dxf} and document.exportDxf; useArtboards
writes one drawing per artboard; selectedOnly (any export) writes the
selection in its layers. Export As lists DXF (then DXF Options,
ui.dxfOptionsDialog for agents, remembered between exports) and DWG
greyed out; document.formats lists DWG and PICT as unsupported with a
hint, and exporting or opening them answers with it.

Clip groups clip by compound paths (with their holes), even-odd paths, text
outlines and groups (the union of their members) on screen, in raster
export, in SVG and in PDF alike, through one shared region:
Node::clip_outline (the model walk) and effects::clip_outline (text
outlined, several shapes united), cached per clipping path in the
renderer. Nothing to clip by hides the clipped art everywhere, and clicks
hit a clip group only inside its clipping region. Make Clipping Mask takes
a compound path or text object on top (it loses its paint) and Release
gives it back unchanged in kind.
