crates/metafile import: EMF and WMF (placeable or not) records play on a
small device-context model (objects numbered as GDI does, saved DCs, world
transforms and mapping modes, path brackets, the current position) into one
artboard (the picture's frame) and one layer: paths with fills and strokes
(pens with caps, joins, dashes), clipping groups for clips, images from DIBs
(StretchDIBits, BitBlt, StretchBlt, AlphaBlend, StretchDIB, DIBBitBlt) and
point type in the font the file names. Lines drawn one after another join
into one path; a clip around the whole picture is dropped; objects far
outside it are left out; unknown records are skipped with one warning.
document.open and file.place read .emf and .wmf through the shared loader
(Open and Place filters list them). clipboard.importEmf loads a picture into
the clipboard, and Paste takes image/emf from a system clipboard service
ahead of text and bitmaps. The import fuzzer covers mutated and random-record
metafiles opened, placed and pasted.

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.

ASCII DXF of any version opens (document.open) and places (file.place) through
a new reader in vectorcraft-cad: lines, LW/2D/3D polylines with bulge arcs,
circles, arcs, ellipses, NURBS splines (exact Beziers up to cubic, fitted
otherwise), solids, solid and pattern hatches, TEXT/MTEXT/ATTRIB as point
type, named blocks as symbols (one per look for by-block art), anonymous
blocks and dimensions as groups, MINSERT arrays, OCS extrusion; layers keep
off/frozen/locked/plot state; ACI and true colour, lineweights, linetypes and
transparency resolve through layers and blocks. The `dxf` option object picks
the layout, ratio or fit, lineweight scaling, centring and merged layers;
document.dxfInfo lists layouts, layers and units. Binary DXF and DWG answer a
clear error. The DXF Import Options dialog (dxfImport) asks on open and place
with a layout preview. Fuzzed in import_fuzz.

- document.save / Save As / Save a Copy to a native or .ai file take
separateArtboards + range (also write <name>-<artboard>.<ext> per artboard
beside the master file, holding that artboard and the art touching it; the
result lists every file), includeLinked (linked images keep their files' own
pixels), embedProfiles (ICC profiles loaded from files that the document is
tagged with; opening installs them where missing) and pdfCompatible (native:
also carry a PDF of every artboard; .ai: false writes blank pages around the
native document). .ai files also take compress (compression.compressText).
- File > Save As to a native or .ai file shows the options dialog (VectorCraft
Options) after the save panel: Save each artboard to a separate file (All or a
range), Include Linked Files, Embed ICC Profiles, Create PDF-Compatible File,
Use Compression, Preview; the web's Save As dialog shows them too. Save, Save a
Copy and Save as Template reuse the options as last saved.
- Format: optional "profiles" and "pdf" members (load_file, pdf_content),
SaveOptions.include_linked/profiles/pdf; files without them are unchanged.
- Changed test: tests_aisave::save_as_ai_writes_a_pdf_that_reopens_editable now
confirms the options dialog Save As .ai shows before writing.

- pdf/src/encrypt.rs encrypts a written PDF with the standard security handler: 128-bit RC4
(PDF 1.4, revision 3; PDF 1.5, revision 4), 128-bit AES (1.6) or 256-bit AES (1.7/2.0,
revision 6), every string and stream, plaintext XMP metadata when asked, the permission bits
(printing none/low/high, five change levels, copy, screen readers). Crypto from RustCrypto
(aes, md-5, sha2: MIT OR Apache-2.0, pure Rust, wasm).
- PDF/A and PDF/X refuse passwords; equal passwords and passwords the algorithm can't take are
refused.
- Opening: the permissions password opens RC4/AES-128 files too; editing data comes back from
an encrypted PDF opened with its password.
- Save PDF › Security: the passwords, permissions and plaintext metadata, the encryption level.

- Every Preferences > File Handling > Data Recovery interval, modified documents
changed since their last copy are written to the recovery store in the
background (the same snapshot and encoder as Background Save; the status bar
shows it). Complex documents (over 20,000 objects) are skipped while Turn off
Data Recovery for complex documents is on.
- A copy goes when its document is saved, reverted, closed or undone back to its
saved state, and when the app quits with nothing unsaved.
- Each running app keeps its copies in an area of its own: a sub-folder whose
.lock file it keeps locked for its lifetime (File::try_lock), or on the web a
heartbeat refreshed every minute. Only areas nobody holds (lock free, or no
heartbeat for three intervals, at least three minutes) are offered, and an
area is held while it is restored or discarded, so a second running instance
never offers or deletes a live instance's copies. Empty leftover areas are
tidied away.
- The next launch after a crash asks with the Recover Documents dialog (Restore /
Discard / Cancel): restored documents open as "<name> [Recovered]", unsaved, and
Save asks where to save them, suggesting their original file; the copy moves
into the new app's area.
- Store: the recoveryFolder preference, else Data Recovery beside the desktop
app's preferences; browser storage on the web (Services::recovery_store);
tests use an in-memory store (with in-memory locks, or heartbeats).
- Engine: file.recovery.save, file.recovery.list, file.recovery.restore {file?},
file.recovery.discard {file?}; DocState.recovered and DocState.recovery.

file.print {settings?, path?} lays the document out on paper and writes one PDF page per sheet:
copies (collated, reversed), artboards (all, a range, ignored), blank artboards skipped, paper
size and orientation (or turned per artboard), transverse, Print Layers (template layers never
print), placement on the imageable area, no scale / fit / custom / tiles of the paper or of the
imageable area with overlap and a tile range; printer's marks and bleed as PDF export draws
them; composite or separations (one grey plate per ink that prints, overprints honoured, spots
as process), emulsion down, negative; rendering intent and preserve numbers. print.preview lists
the pages, tiles, inks and warnings; print.setup saves the settings with the document
(Document.print_setup, one undo step).
PDF export and print share one page writer; the ink separation helpers move from the renderer to
vectorcraft_doc::inks and the range parser to vectorcraft_doc::range so print can use them.

command.batch kept its steps in one interaction of the document active
when it began and journaled itself by committing that interaction. A
step that opened, closed or reverted a document broke both: the switch
cancelled the interaction (throwing away the steps so far), and the
commit then ran in the new document, which had none, so the batch was
never journaled and a replay was missing the new document. An error
after the switch rolled back only the active document.
- Each step runs inside an interaction of the document active when it
starts; a switch leaves it open while a batch runs, so every document
the batch edits gets one undo step when it succeeds.
- The batch journals itself, whichever document it ends in.
- On error everything rolls back: documents the batch opened close, the
ones it closed or reverted come back (Session::batch_stash), each
one's interaction is undone, and the active document and the
Untitled-N count go back too.
- DocState::keep_interaction / undo_interaction share the undo-step and
rollback code with commit_interaction / cancel_interaction.
- Tests: a batch that opens a new document is journaled, replays to the
same documents and keeps one undo step in each; a failed batch closes
the document it opened and restores the one it closed; a failed batch
brings back a document it reverted.

Session::note_journal only kept values noted by the top-level command, so
a command run as a step of command.batch lost them: a save in a batch
stamped File Info's modified date from the clock without recording it,
and object.scale's strokes/corners came from the preferences again on
replay. Replaying such a journal a second later (or with other
preferences) gave a different document.
- Session::execute_step runs a batch step with its own journal notes
(note_depth) and returns its params with what it noted; command.batch
writes those params into its step of the batch's journal entry (steps
that note nothing stay as given).
- journal_for_action strips the replay-only dates from a batch's steps
too, so an action recorded with one still dates the document when it
plays.
- Tests: a save in a batch records its date and a replay with the
recorded date moved lands on it, while an action leaves it out; a scale
in a batch records Scale Strokes & Effects and replays alike with the
preference off.

pasted_pdf_never_panics failed at random (about one run in four at 256
cases): a mutated digit turns a curve coordinate like 245.18535 into
245018535, so the pasted art spans ~1e8 pt, beyond MAX_COORD, and
edit.paste rightly refuses it with "result would exceed the canvas",
leaving the document unchanged. The helper unwrapped that result. The
test is about never panicking, so paste_from_elsewhere now ignores an
Err from edit.paste, with a comment saying why.

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).

SVG has no freeform shading: an object's freeform fill or stroke is now
written as an <image> of the colour field over its painted box, sampled
on the grid the canvas uses (twice the box's size in points), clipped to
the shape or to the stroke's outline, with the fill or stroke opacity and
blend mode on the group. Linked image mode writes the PNG next to the
SVG. Character paints keep the linear approximation (with a warning);
gradients along or across strokes stay vector slices. The grid sizing
moved to the colour crate so the canvas and the export share it.

SVG export writes UTF-8, UTF-16 (big-endian with a byte order mark) or
ISO 8859-1 (other characters as character references) and SVG/SVGZ
open in any of them. The Tiny 1.2 profile (simplified) writes
presentation attributes only and leaves out filters, masks, blend
modes and symbols with warnings. embedFonts embeds the fonts type uses
as @font-face subsets of the characters used, honouring the fonts'
fsType (whole when subsetting is forbidden, left out when embedding
is). New options: encoding, profile, embedFonts (SVG Options dialog,
document.formats); document.serialize also returns dataBase64 for
non-UTF-8 files.

Artboards: All, a range or Full Document (one file per format: a PDF of
every artboard, other formats the bounds of all art), Include Bleed
(artboards grown by the document's bleed). Rows size files as a factor,
100w, 100h or 72ppi (suffixes @2x, @100w, @100h), and choose PNG, PNG 8,
JPG 100/80/50, WebP, GIF, SVG or PDF. Create Sub-folders (by size, by
format, or a row's own folder) and the presets Mobile 1x/2x/3x and
Density buckets (ldpi…xxxhdpi sub-folders). The gear opens Format
Settings: per-format options for every row of that format (the raster
and SVG options dialogs' rows, the PDF preset). Open Location after
Export shows the first file. The dialog has Artboards and Assets tabs.
The params of the last export are saved in the document
(Document.export_settings, not an undo step), read with
document.exportSettings, and the dialog reopens on them.

document.exportForScreens takes zip: true to pack every file into one
store-only .zip (returned as dataBase64 without a folder, written there
with one); without a folder the files come back as base64. The engine's
Export for Screens moves to fileio/screens.rs, with a small ZIP writer
(fileio/zip.rs).
The dialog starts in the user's Desktop (else home, on every OS), has a
folder picker button (the Services.pick_folder the Links panel uses) and
stays open when the export fails. On the web it has no folder: OK reads
"Download" (DialogSpec.ok_label) and the files download, several as one
zip. file.exportForScreens with params goes through io::export_for_screens.

document.exportPdf {marks} now draws trim marks (Roman or Japanese, at the
trim mark weight and offset, outside the bleed), a registration target at the
middle of each side, colour bars (process inks, their overprints, the
document's spot inks and black tints) and the page information (title,
artboard, export date in UTC). Marks print in [Registration] (/Separation
/All), the MediaBox grows to hold them and the art is clipped to the
BleedBox. The geometry is the shared vectorcraft_doc::marks::PrinterMarks
(built on TrimMarks) so print can draw the same marks. The "not drawn yet"
warning is gone.

document.exportPdf applies the bleed (the document's with bleed.useDocument,
else the custom values): each page's TrimBox is its artboard and its BleedBox
and MediaBox the artboard grown by the bleed, so art in the bleed is kept.
Layers whose Print option is off are left out unless includeNonPrinting (new
setting, Save PDF › General) or createLayers is on. The bleed warning is gone;
the Marks and Bleeds section shows the document's bleed when it is used.

Optional content groups become layers (in paint order, shared by every page)
with their name, default visibility, print usage and lock; art outside them
goes to a layer per page. Art that is off isn't lost: an update appended to
the file drops its /OCProperties so the interpreter draws every group, and
the marked-content sequences found walking the content (checked by tag) route
the art to its group's layer, which comes in hidden. A form hidden by its own
/OC keeps the file as it is. document.open layers: false keeps one layer per
page of only what shows (Save then asks for a name).

Luminosity soft masks become opacity masks (alpha masks as a white copy of
their art; backdrop colour gives Clip, an inverting transfer function Invert;
the PDF export's backdrop and Difference covers read back as the options; a
constant alpha mask is opacity). Transparency groups keep their /I and /K
flags (read by walking the content as the interpreter does). Tiling patterns
become pattern swatches (one per colour for uncoloured ones). Text becomes
point type, one object per line with a run per font and paint, fonts named
from the file (document.open textAs: text | outlines). Patch and triangle
mesh shadings become gradient meshes; gradients drawn through their grey
opacity mask get stop opacity back; shadings that don't extend clip the art.
A rectangular clip around all its art (a form's box) is dropped.

The Slice tool (Shift+K) drags out a user slice (Shift square, Alt from the
centre, snapping to ruler guides) as one undo step through
object.slice.create. The Slice Selection tool selects slices (Shift
toggles, object.slice.select), moves them (object.slice.move; object
slices move their objects), resizes a user slice by its handles
(object.slice.setRect), opens Slice Options on a double click and deletes
with Delete (object.slice.delete). Hidden or locked slices can't be
picked. Both tools have cursors drawn in code.

Document.slices holds user slices, Node.slice makes an object an object
slice that follows its bounds, and Document.slices_clip_to_artboard picks

Object → Slice: Make, Release, Create from Guides, Create from Selection,
Duplicate, Combine, Divide… (dialog), Delete All, Slice Options… (dialog)

slice.list reads the numbered layout. The canvas draws the slices in the
Slices preferences' line colour with their numbers.

File > Package (saved documents; unsaved changes are saved first) writes
<folder>/<name>/<document>.vectorcraft, the linked files in Links/ (relinked in the
packaged copy), the fonts its type uses in Fonts/ (leaving out fonts whose licence
doesn't allow embedding) and <document> Report.txt, then offers Show Package. Without a
folder (the web, agents) the same files come back as a zip.
Document Info's flyout picks one category (document, objects, styles, spot colours,
patterns, gradients, symbols, fonts, font details, linked and embedded images) and Save…
writes the text report Package shares.
Engine: file.package {folder?, name?, copyLinks?, linksFolder?, relink?, copyFonts?,

The Links panel lists every image (thumbnail, name, page, missing/modified/embedded
badge) with Show filters, sorting and thumbnail sizes; its buttons and flyout relink
(to a file or a folder), go to, update, edit the original, embed and unembed, show in
folder and open Placement Options. Link Info shows format, colour space, location, ppi
and effective ppi, dimensions, scale, rotation, size and dates. Edit > Edit Original
and the Properties panel's image section reach the same commands.
Engine: links.list, links.goTo, links.embed, links.unembed, links.info and
links.placementOptions; links.relink and links.update now place the new file as the
image's Placement Options say (transforms, bounds, file dimensions, fit, fill, the
alignment point, clip to the old bounds). Model: ImageObject.placement.

- The status bar shows a spinner and what is being written; ui.inspect lists
the running jobs under `background`.
- The document takes the path and counts as saved as of the snapshot once the
file is written: edits made meanwhile keep it modified.
- Quit and Close wait for running saves; the Save Changes dialog saves at once.

- Every file write goes to a temporary file renamed over the target (engine
writes and the desktop app's writer), so a failed save keeps the old file.
- Only the images the document uses are written.
- Document keys from newer versions are kept (Document.extra, flattened).
- Assigned colour profiles are a real field (Document.color_profiles),
migrated from unknown.colorProfiles on load.
- document.save {version: 1|2} writes files older versions open; {preview}
embeds a PNG of the first artboard of at most 256 px.

document.open {path} (and File > Place) find an SVG's relative <image>
links in its folder: raster files stay linked images (LinkInfo with size,
time and hash), SVG files and data: SVGs import as vector art, and a file
that can't be read becomes a placeholder in its box that keeps the link,
with a warning and a missingLinks row (Update Links / Relink read it
later). The SVG library itself reads no file unless given a reader.
Nested clip paths become clip groups in clip groups; undisplayed objects
(display:none) come back hidden; spreadMethod reflect and repeat are
expanded into stops over the painted area (matching resvg). Midpoint stops

<symbol> with <use> imports as a symbol (named after data-name or its id)

feDropShadow and the usual shadow chains (offset, blur, flood or colour
matrix, composite, merge) become Gaussian Blur, Drop Shadow, Outer/Inner
Glow and Feather effects; other filters are still reported. Export records
the symbol name and the shadow/glow blend mode so export -> import keeps
them. <pattern> keeps importing as a pattern swatch (now tested).

Alter Paths for Appearance, Outline Text.
document.export {format: dxf} and document.exportDxf; useArtboards

Colour, greyscale and monochrome (black-and-white) images placed above the
threshold resolution are resampled to the target (average, subsample or
bicubic) and compressed with ZIP, JPEG at the chosen quality, or
automatically (JPEGs stay JPEG, the others lossless); images already as
asked are embedded unchanged. JPEG 2000, CCITT, Run Length and no
compression are written as ZIP with a warning when an image needs them;
images with transparency stay lossless. Images no longer ask viewers to
smooth them in PDF/A files.

Pattern strokes are written as the pattern's tiles clipped to the stroke's
outline (dashes, caps, profile, arrowheads and alignment included) instead
of mid-grey; freeform gradients on fills, strokes and type as an image of
their colour field at the document raster effects resolution, clipped to
what they paint, instead of their average colour. Both read back within
2% of the canvas at 150 ppi with no warning. Text strokes are covered for
cap, miter limit, dash array and alignment; knockout groups keep their
soft-masked form with a warning. The freeform box and grid sampling are
shared with the renderer.

PDF export now renders the shadows, glows, blurs and feathers of groups,
layers, type, images, symbol instances, live objects and single fills and
strokes (and those inside opacity masks, symbol definitions and pattern
tiles) as images at the document raster effects resolution, instead of
leaving them out with a warning. Shadows and outer glows go under the
untouched vector art; a path whose fills or strokes carry effects is
written as one piece per fill and stroke. Expand Appearance shares the
image helpers (moved to rasterfx.rs); effect images now cover what the
renderer paints (members' shadows included).
