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.

Finder, Open With, a drop on the Dock icon and `open -a` failed with "VectorCraft cannot open
files in the PDF document format":
- The release Info.plist declared no document types, so Launch Services refused the files before
the app saw them. Info.plist.in now declares every format File › Open reads (the engine's
OPEN_EXTS; a test keeps them in step): VectorCraft owns its own documents and templates and is an
alternate for the others, so it takes over no other app's files. `cargo xtask bundle` now fills
in the same template instead of its own, shorter plist.
- macOS delivers such files as open-document events, not arguments. winit 0.30's application
delegate has no `application:openURLs:`, so AppKit fell back to NSDocumentController, which
refuses every file of a non-NSDocument app (the error in both issues). The new
`open_documents` module adds that method to the delegate's class when the app is about to finish
launching (before AppKit delivers launch files), queues the paths and wakes the UI, which opens
them with `io::open_path` like command-line files; errors go to the status bar too.
New direct macOS dependencies `objc2-foundation` 0.3 and `block2` 0.6 were already in Cargo.lock
(through winit, muda and rfd). The module allows `unsafe_code` for the Objective-C runtime call.

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.

The ROADMAP and the MCP docs say Illustrator/Adobe again where they compare
VectorCraft with it (the rewording in #15 and the create_graph row). The
vendor-name gate keeps checking what users and agents read in the app (Rust
string literals, Cargo descriptions, packaging) and the non-Markdown files
under docs/, and no longer scans Markdown pages.

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.

Edit -> "PDF Presets…"; the clipboard preferences read "Legacy vector
clipboard (no transparency)" / "Legacy vector clipboard" (keys copyAicb and
aicbMode unchanged); the second keyboard shortcut set is "Classic Defaults",
and the old set name is still accepted from saved UI preferences, imported
sets and shortcuts.preset. The MCP server instructions, the apply_effect and
create_graph tool descriptions, the text.createInPath params doc,
docs/mcp.md, the ui-egui crate description and the PDF compatibility docs
no longer name another vendor.
New `cargo xtask brands` (run by `cargo xtask ci`) fails on vendor product
or company names in Rust string literals (labels, params docs, menus,
panels, MCP definitions; comments and test code skipped), Cargo.toml
descriptions and text under docs/ and packaging/; a required legacy alias
is marked `brand-ok`. xtask shares one git file listing between the asset
and brand checks. docs/development.md describes the gate.

Drop the file types and wording carried over from the sibling raster
editor: the macOS exported type now declares .vectorcraft/.drawcraft
(was .pcraft) and the raster imported types (large raster documents, QOI)
are gone; the dev bundle's PDF type is "PDF Document"; Linux categories and
keywords say vector graphics (no trademark keyword), the AppStream
description and screenshot show VectorCraft, and the deb/rpm, MSI and web
embedding descriptions say vector illustration app. File associations stay
as they are. An xtask test rejects raster-editor wording in packaging/.
