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.

- Edit Contents: while an envelope's contents are edited, clicks hit the
content where it sits undistorted and the Selection tool selects it; the
menu item reads Edit Envelope then. No default shortcut: the reference
app's (Shift+Cmd+V) is Paste in Place here.
- A selected envelope shows its mesh (a warp's surface grid, a mesh's own,
a top object's outline) instead of its content's outlines.
- Mesh envelope points get bezier handles (append-only; none stored is the
smooth Catmull-Rom mesh, which the first handle edit fills in exactly
along the grid lines). setMeshPoint takes `handle`; object.mesh.movePoint,
addLine and deletePoint edit mesh envelopes too. The Mesh tool and Direct
Selection drag points and the clicked point's handles (shared MeshEdit);
the Mesh tool adds rows and columns inside mesh envelopes. Reset with
Mesh keeps the shape along the grid with handles; Release returns the
exact mesh.
- Control bar: Edit Envelope / Edit Contents, warp style, orientation,
bend and distortions or mesh rows and columns, Reset, Envelope Options.

- Images distort as a raster mesh warp: cut by Fidelity into triangles,
each a clipped image under the affine map of its corners (pieces overlap
slightly, no seams; the renderer paints them without clip layers; SVG
writes the pixels once and <use>s them).
- Symbol instances distort as their symbol's art (the renderer's cache
follows edits to the symbol).
- Distort Appearance bakes strokes (filled outlines) and geometry effects
before bending; Distort Linear Gradients bends linear gradients; Distort
Pattern Fills bends the tiles. Opacity masks of the content bend too.
- Bug fix: a rotated, sheared or reflected warp envelope re-warped along
the page axes. Envelopes now keep their own frame (append-only model
field), so the warp turns with the art; move and scale keep it square.
- Live evaluation shares one set of hooks (vectorcraft_doc::live::Hooks,
vectorcraft_effects::{expand_live, expanded_live_group,
expand_live_deep}) between the canvas, Expand and every exporter.

Closed shapes start where they twist least (unless the Blend tool
picked the anchors); dashes, miter limit, arrowhead scale and width
profiles interpolate (caps, joins and brushes switch halfway);
gradients with different stop counts resample to common stops; groups
with different member counts grow the extra members out of a point;
compound steps stay compound paths; type, symbol instances and images
interpolate their transforms, type its colours and sizes run by run.
New blends are knockout groups and the canvas draws them knocked out
as the exports do. Expand and Release keep the blend's name,
transparency, opacity mask and appearance, and Object > Expand expands
blends.

A selected blend shows its spine. Direct Selection drags spine points
and handles, the Pen tool adds and deletes points on a selected
blend's spine (object.blend.spine.moveAnchor/addAnchor/removeAnchor).
The straight spine becomes a path on the first edit, its points pinned
to the key objects (append-only BlendSpec.key_anchors): moving a key
moves its end of the spine and the other way round; spines from older
files and Replace Spine still spread the keys evenly. Direct and Group
Selection pick blend keys on the canvas, edits redraw the blend live,
and Release leaves the spine as a path.

Blend Options is a dedicated dialog (Spacing dropdown with its value,
Align to Page / Align to Path buttons, live preview) opened on the
selected blend's own options, so OK no longer turns Smooth Color into
5 steps; with nothing selected it sets what new blends start with
(object.blend.info reads them). The Blend tool blends from clicked
anchor points (blend spec `starts`), adds keys to an existing blend
instead of nesting it, opens Blend Options on double-click, Alt-click
and its toolbar button, and has its own cursors and hint.

Make with Warp and Make with Mesh open dedicated dialogs (style dropdown,
orientation, bend and distortion sliders; rows and columns) with live
preview; while an envelope is selected the menu shows Reset with Warp /
Reset with Mesh instead, which switch the envelope's kind and keep its
content (Maintain Envelope Shape samples the current surface). Envelope
Options is a full dialog prefilled from the selection (Anti-Alias,
Preserve Shape, Fidelity, Distort Appearance, Distort Linear Gradients,
Distort Pattern Fills); with nothing selected it sets the defaults for new
envelopes. object.envelope.info reads the settings. Release returns the
warp or mesh shape as a gradient mesh and keeps opacity, blend mode and
mask; Expand keeps name, knockout, isolation and mask; Object > Expand
expands envelopes.

Shipped code no longer unwraps, expects or panics: every one of the 124
unwrap()/expect()/panic!/unreachable! sites outside tests now handles the
failure (Result/Option, ?, let-else, defaults) and reports errors to the user.
- Lints: workspace clippy denies unwrap_used, expect_used, panic, todo,
unimplemented and unreachable; clippy.toml allows them in tests, and
integration tests, examples and testkit opt out explicitly.
- Safety net (vectorcraft_engine::guard): a panic in a top-level command rolls
the document back and returns EngineError::Internal; a panicking tool is
reset; the MCP server answers with an internal error and keeps serving; the
UI frame and each control request are guarded.
- APIs that hid failures now return them: Rendered::to_png/to_jpeg/to_webp
return Result (JPEG/WebP errors used to write empty files),
FontDb::face returns Option, Region::top returns Option.
- Fuzzing: engine/tests/import_fuzz.rs feeds garbage, hostile and mutated SVG
and PDF through import → render → export (30k cases locally, no panics).
- Docs: AGENTS.md/CLAUDE.md rule, docs/development.md "Robustness" section,
README pointer and a PR template checklist.

Radial gradients show a dashed extent ellipse: its handle across the bar
sets the aspect ratio, the ellipse elsewhere rotates it, and the dot inside
the centre ring drags the focal point (GradientGeom.focal) for an off-centre
radial. paint.setGradientGeom takes aspect (%) and focal ([x,y] | null), and
start/end may be left out; the focal point keeps its place in the ellipse as
the vector, aspect and object transform. It renders as a two-point radial,
exports and imports as SVG fx/fy and PDF two-point radial shadings, expands
to off-centre rings, and travels in gradient params and the native format.

Colours gain a CIE Lab model (`Color::Lab {l,a,b}`, serde tag `lab`), handled through the
CMS (display, separation, conversions, gamut), tints (toward paper white), keep_model, harmonies,
recolouring, blends, Info and the Color panel. Swatch Options gets a Lab mode
(`swatch.edit {mode: "lab"}` / `{color: {l,a,b}}`), and colour params accept `{l,a,b}`.
Swatches panel → Spot Colors… (`ui.spotColors`, dialog `spotColors`) runs `swatch.spotOptions
{useLab}` (Document.spot_use_lab, default on): Lab spot colours show and separate from their Lab
values, or art linked to them takes their working-CMYK equivalents, as one undo step. PDF export
writes Lab spot inks as Separation spaces with a Lab alternate (tint function from paper white),
or a DeviceCMYK one with CMYK equivalents.

Object > Expand… opens a purpose-built dialog (Object, Fill and Stroke
checkboxes, disabled when the selection has nothing for them; Expand
Gradient To: Gradient Mesh or Specify N Objects, default 255). Every
option now does something:
- Object: type to outlines, live shapes to paths, effects baked.
- Stroke: strokes outlined into filled paths.
- Fill: linear/radial gradient fills become N solid rectangles or
concentric ellipses, or a gradient mesh with lines where the colour
changes, inside a clip group shaped like the object; freeform
gradients become a mesh shaped like the object. Colours keep their
stops' colour model. With Fill off gradient fills stay live.
object.expand {} defaults match the dialog (stroke now defaults on);
new query object.expand.info and UI command ui.expandDialog.
Create Gradient Mesh on a gradient-filled object takes the colours the
gradient paints at each point (GradientMesh::for_path_with, from_grid,
highlight).

New Node.knockout_shape (transparency.set / object.setProps knockoutShape,
reported by transparency.info). In a knockout group such an object knocks
out only as much as its opacity and mask let through (a 50% object knocks
out 50%); otherwise its full coverage knocks out. The renderer, PDF and
SVG masks honour it, and the panel's checkbox is now live.
