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.

An Illustrator EPS is a flattened page plus, after %%EOF, an editing copy of
the document; a PDF-compatible .ai carries the same in its private data.
Importing only the page lost layer names, order, visibility, hidden layers
and hidden objects and hidden text.
- eps: read the editing copy (Zstandard %AI24_DataStream, older zlib
%AI9_DataStream) into layers, sublayers, groups, compound paths, clip
groups and hidden objects, run by the existing PostScript interpreter.
Falls back to the page, with a warning, when a shown layer uses an
operator that isn't read or the art differs from the page by over 5%.
- eps: read the text document (ate.rs) to place type on hidden layers and
objects; the page's type is matched to the file's text objects by
position (pieces of a line included) and kept with the nearest one when
none claims it. Area type and type on a path are left out with a note.
- pdf/engine: .ai files go through the same reader.
- engine/cli: a file whose import left things out isn't overwritten unless
asked (acknowledgeLoss, --replace-lossy).
- eps: font names re-encoded with a *<n> suffix resolve to their family.
- i18n: es/it/ru for the new import messages; ROADMAP updated.
Container and text-document formats were inferred from user-owned files; the
Adobe file format specification was not read.

Open and Place read Affinity documents natively (.af from Affinity 3,
.afdesign/.afphoto/.afpub from Affinity 1 and 2): layers and sublayers,
groups, artboards with their names and backgrounds, Publisher pages side
by side, curves with live corners, parametric shapes, compound shapes,
clipping by nesting, vector and pixel masks, solid and gradient fills,
strokes, fill layers, artistic and frame text, placed images (their
original JPEG/PNG), pixel layers, embedded documents as their cached
picture, opacity, visibility, locking and blend modes, at the document's
resolution in points. Unsupported content (effects, adjustments, brushes,
master pages, special shapes, Affinity-only blend modes...) is listed in
the import warning, one line per kind. A file whose native data can't be
read opens as its embedded preview with the reason, and that preview
cannot be placed or used as a template or library. Save never writes back
over the Affinity file and there is no Affinity export.
The document semantics were fitted to the thumbnails Affinity embeds in
176 public documents. `cargo xtask corpus --affinity` fetches 22 public
CC0/MIT/Apache-2.0 documents at pinned commits, sha256-verified; the new
engine test renders each and compares it with Affinity's own thumbnail
(0-4.4 of 255 mean difference, per-file ceilings). import_fuzz mutates a
synthetic native document's stream and container through open, render
and export; the fuzz crate gains a stream target.

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.
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).

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.

file.place {path | name+dataBase64, link, template, replace, at, rect, page, crop} places a
file as one undo step without touching the clipboard. Raster images come in at 100% of the
resolution their file declares (PNG pHYs, JFIF/EXIF, TIFF, BMP; 72 ppi otherwise), linked to
their path by default; SVG becomes one group with its embedded images; a PDF/.ai page or a
native document's artboard becomes one clipped group. The images, symbols, patterns and
swatches the art uses join the document (renamed on conflict). Replace keeps the replaced
object's stacking place and transform; Template puts the art on a new locked template layer
below the current one. file.place.info and image.info report size, ppi and colour mode.
File > Place picks a file and opens the Place dialog (Link, Template, Replace); the web picks
through the inbox. The Control bar shows Linked File/Embedded, the file name, colour mode and
ppi of the selected image.

svgz is a writable format with the SVG options (document.export,
serialize, save, Export for Screens): exactly the SVG export, gzipped.
SVGZ is recognised by its extension or the gzip magic bytes and opens,
places and pastes like SVG (clipboard.importSvg takes dataBase64 of SVG
or SVGZ); Export As SVG or Save As to a .svgz name writes it
compressed. Gzip lives in the svg crate (pure-Rust flate2, builds for
wasm) and unpacking stops at 512 MB.
