A plug-in could filter objects or reshape them as a live effect, but
nothing it made could leave the app: pen plotters, cutting machines and
laser cutters read formats VectorCraft doesn't write. An exporter is a
third kind of plug-in ("kind": "exporter", with the file "extensions"
it writes), in the same sandbox and with the same ABI v1 exports.
- It adds a write-only format, plugin.<id>. document.formats lists it
with its plug-in id, and document.export writes it by that id, or by
a path ending in one of its extensions that no built-in format has;
"params" carries its parameters, checked against its manifest as a
filter's are.
- File › Export › Export As lists it after the built-in formats, with
Use Artboards greyed out, since the plug-in writes the whole
document. One with parameters asks for them in a dialog generated
from its schema (pluginExport) once the file is picked.
- The plug-in is given the native file's JSON (format::json_part:
images of 8 KiB or more without their data) and _context {mode:
"export", extension, name}. It returns {"dataBase64", "warnings"?}
or {"error"}. The host writes the file, and nothing when the plug-in
declines or returns bad data.
- An export gets 10 G instructions plus 4,000 per byte and 300 s.
Background Export's Cancel stops it between two slices of that
budget (Error::Cancelled), and a cancelled live-effect run is not
cached as a failure.
- plugin.run and Object › Plug-ins say where an exporter is instead of
calling it a live effect.
engine/tests/plugin_export.rs reads back what an exporter is handed
with wat::echo_exporter, an exporter whose file is its input or its
parameters (its base64 encoder is written in WAT). The document it is
given is document.save's JSON, without the large image's data, and its
parameters arrive defaulted, clamped and with the file's name and
extension. It also covers listing and removal, built-in extensions
winning, selectedOnly, declines, bad base64, missing data, warnings,
and Cancel stopping a plug-in that never returns. It is a test binary
of its own: installed plug-ins are process-wide, and the format-list
unit tests check exact lists. dialogs/tests_plugin_export.rs drives
Export As headlessly; plugins/tests/abi.rs covers the budget, the
parameters and the echo exporter; format/tests/native_v4.rs covers
json_part.

A .vectorcraft file's type opened with the character and paragraph
values it held. With a size of 0, the characters were not drawn. With
a size, leading, horizontal scale, left indent or space before of
1.797e308, point type's bounds were infinite or over 1e308 wide or
high, and moving or scaling it failed with "result would exceed the
canvas".
These values are now read into range when a file opens, in the type of
the layers, symbols, graph designs, patterns and the pattern definition
that Cancel puts back in pattern editing mode, and in character and
paragraph styles. A size, horizontal scale or vertical scale of 0 or
less becomes 12 pt or 100%, and a negative leading becomes Auto. A
size, leading or scale past 4,000,000 (MAX_COORD) becomes 4,000,000,
and a baseline shift, indent or space before or after past 4,000,000
either way becomes 4,000,000 or -4,000,000. A tab stop is kept to the
0 to 100,000 pt that text.tabs.set takes. A leading of 0, which legacy
.ai import stores, and the sizes, scales and indents within these
limits that SVG, PDF and .ai import keep outside the panels' ranges
open as saved.
Docs: docs/mcp.md (Paragraph attributes per paragraph).
document.setup accepts a superscript and subscript size of 1 to 500%
and a position of -500 to 500%, and a small caps size of 1 to 200%.
text.setFormat copies these proportions into the characters it
formats. A .vectorcraft file's characters, character styles and graph
label styles opened with the proportions they held. With a superscript
size of 0, the superscript characters were not drawn, and with a
superscript or small caps size of 1.797e308, moving the type failed
with "result would exceed the canvas".
These proportions are now read as the nearer end of each range when a
file opens: in the type of the layers, symbols, graph designs, patterns
and the pattern definition that Cancel puts back in pattern editing
mode, in graph label styles and in character styles. Proportions in
range and the other character attributes open as saved.
Docs: docs/mcp.md (Small Caps, Superscript and Subscript).
file.new takes a width and height up to 163,830 pt, 1 to 1,000
artboards, a spacing of 0 to 100,000 pt and a bleed of 0 to 72 pt a
side, but a saved or Recent New Document preset in the preferences
was read as it was stored. With a width of -5, file.new failed with
"width/height must be positive and within the canvas"; a spacing of
-50 overlapped the artboards, a preset with 5,000 artboards made 5,000
artboards, and a bleed of 100 reached the document. A .vectorcraft
file's Document Setup bleed, superscript and subscript proportions and
small caps size also opened as stored, and document.setup then failed
when its own report was passed back to it.
These values are now read as the nearer end of the range their
setter takes, and an artboard width or height of 0 or less is read as
1 pt. Presets and files with values in range read as before.
Docs: docs/mcp.md (Document Setup, New Document).
document.rasterEffectsSettings accepts a resolution from 1 to 2,400
ppi, but a file's raster_effects_ppi opened as it was saved. With 0,
-5 or 5000 in the file, object.rasterize without a ppi param failed
with "ppi must be between 1 and 2400", and document.rasterEffectsSettings
and document.info reported the stored value. With 0 or -5, EPS and
PDF export wrote a freeform gradient as a 1 x 1 px image, and EMF
export wrote every gradient as one. A saved New Document preset in the
preferences kept such a value too.
A file's or a saved preset's resolution outside 1 to 2,400 ppi is now
read as the nearer end of that range. Documents with a resolution in
range open as before.
Docs: docs/mcp.md (resolution, rasterEffectsPpi).
document.rasterEffectsSettings accepts addAround from 0 to 1,000 pt,
but a file's raster_effects.addAround opened as it was saved. With
addAround 1e300, the area of a raster effect image overflowed f64,
the image scale became 0 and the image got the transform
[inf, NaN, NaN, inf, x, y]. PDF export left that image out, so the
drop shadow was missing.
A file's addAround now opens clamped to 0 to 1,000 pt. An effect
image whose area or scale is not finite is not made. Export then
keeps the object with its effects, and Expand Appearance expands it
without an image, as when its PNG can't be encoded.
Docs: docs/mcp.md (addAround).
SaveOptions::for_doc chose pretty-printed JSON by the object count in
the layers alone. A document with few layer objects but many anchors,
or with its art in symbols, patterns or graph designs, was therefore
written pretty, about ten times the compact size: every anchor's "p",
"in" and "out" spread over several indented lines.
A document is now pretty only when it has at most PRETTY_MAX_OBJECTS
objects and its compact JSON is at most PRETTY_MAX_BYTES (1 MiB). The
size is measured by serializing into a writer that stops at the limit,
so a large document costs at most 1 MiB of extra serializing. Small
documents stay readable and diffable.
Fixes#1484
Save serializes JSON straight into the compressor and writes images from their Arc into the
file; open reads each image into its own buffer, and NodeKind reads its tag first instead of
buffering every node. Already-compressed images are stored rather than deflated again in the
same gzip stream. Limits apply per section, so any file VectorCraft writes opens again. Data
Recovery writes each image once, content-addressed, instead of every interval. Native files open
on a background thread. Files stay readable by main both ways; JSON-only saves are identical.

Rarely set fields move into one optional boxed NodeExtras, and large NodeKind payloads (images,
live shapes, blends, envelopes) are boxed. Every object, and every undo step that copies it,
shrinks: a 50k-path move keeps ~24.5 MB per step instead of ~40 MB. Files stay byte-identical
(Node keeps its flat JSON through a borrowed Serialize and a from-wire Deserialize, no flatten),
and loading is slightly faster. Undo and redo reuse their step's size estimate instead of
walking the document again (8.3 -> 5.6 ms for a 50k-path move).

Graph designs are named art a graph draws in place of its default
marks. Marker designs follow
https://helpx.adobe.com/illustrator/desktop/automate-visualize-data/visualize-data/apply-marker-designs-to-graphs.html
and the Graph Design dialog
https://helpx.adobe.com/illustrator/desktop/automate-visualize-data/visualize-data/reuse-graph-designs.html
- graph.design saves the selected art as a named design (Save Design),
pastes a copy of a design into the document, selected, to edit and
save again (Paste Design), and deletes one; graphs drawing a deleted
design go back to their default marks.
- graph.marker draws the data points and legend swatches of the series
picked with Group Selection (or listed, or every series) with a
design: its backmost object is scaled to fill the default marker's
square, strokes, effects and pattern tiles scaling with it. Line,
scatter and radar series; null goes back to the default square.
- Object › Graph › Design… and Marker… open dialogs listing the
document's designs.
Own choices, as the pages don't say: the backmost object's bounds, not
only a rectangle's, set the size (a single object uses its own bounds);
Delete Design manages the list; a design keeps its own paint, so
painting a series doesn't recolour it.
Designs are stored in a new `graphDesigns` list and series designs in
`seriesMarkers`, written only when present. A graph saved as a design is
kept as the plain art it draws. A design holds at most 2,000 objects, a
document 1,000 designs, and a graph whose designs would draw more than
200,000 objects draws default squares; a file's designs are tidied the
same way on open. Global swatch edits, image relinking and placed
documents see design art like symbol art. Graphs without marker designs
draw the same art as before.
At 50,000 paths unless noted, against main:
- Pathfinder Outline (300 paths): 145 → 7.5 ms. Each segment was tested against every junction
of the arrangement, and each chain against every chain kept so far. Now a segment tests only
the junctions inside its control box (junctions are sorted by x; a point within reach of a
curve is within reach of that box), with the same nearest-point test. Coincident chains are
found through a grid on their midpoints, taking the first match in the same order a scan does.
- export SVG: 267 → 176 ms. Path data is written straight into one string (`push_num`, the
same digits and trimming as `fmt_num`) instead of a string per number, point and segment.
- open .vectorcraft: 239 → 195 ms. The JSON was parsed once only to find where it ends:
- A file with no NUL has no data after it.
- Otherwise the marker (which holds the first NUL, as JSON can't) is taken when it directly
follows the JSON's last byte, as the writer puts it.
- Anything else takes the old parse.
`perf --deep` prints output hashes of an SVG export and a save → open → save round trip; main
and this branch print the same ones. pathfinder_pinned (Outline included) passes, and so do the
pathops, format and svg suites (345 tests).

When a document opens with fonts that aren't available, fonts used
only in its symbols included, VectorCraft lists them in a Missing
Fonts dialog after the missing linked file questions, one document at
a time, with Find Fonts and Close. Find Fonts opens Type › Find Font
on the first missing font of the layers' type, to replace it. After
Find Fonts or Close the dialog doesn't open again for that open; when
another dialog replaces it, it opens again once that dialog closes.
Search Fonts Folder (the Fonts folder File › Package writes next to
the document) and Find in Folder… search a folder and its subfolders
for the fonts' files, and Add Fonts copies the files the user chooses
into a Fonts folder next to the preferences. The desktop app and
vectorcraft-cli read that folder with the system's font folders. Type
› Find Font has a Find in Folder… button too when fonts the document
uses are missing. The web app shows no dialog; a status message says
how many fonts aren't available.
- text.missingFonts lists each missing family and style once,
whatever version the document's type names, and leaves out CSS
generic families such as sans-serif. text.findFontFiles searches a
folder on up to 8 threads and returns at once; text.findFontFiles {}
reports the search, and {stop: true} stops it. A search reads only
what the font scan reads of font files (their table directories and
name, fvar and OS/2 tables) and, on macOS, of suitcase fonts, and
lists a file for a font only when the file makes the font resolve
exactly. It does not enter app packages, the Program Files and
ProgramData folders, the system's folders at the root of a volume,
the Shared and Public folders in Users, a home folder's Library,
AppData, Applications, snap and dot folders, a Library folder's app
data folders or the folders the environment names for apps, and it
skips other hidden folders and does not follow links below the
picked folder. It ends after 60 s by default, after 10,000,000
entries listed, with more than 1,000,000 folders waiting, after
10,000 font files read or 1,000 kept, or once every font has a file;
Stop and Close end it too.
- text.addFontFiles copies only files the last search found. Of
those, it copies only regular .ttf, .otf, .ttc, .otc, .woff and
.woff2 files and suitcase fonts with their resource fork, at most
256 MB a file and 1 GB in all. It never replaces a file: a file with
the same contents is kept, and when another file has that name, the
copy gets a number (Name 2.otf). The fonts are then scanned again,
and type set in them redraws.
- ui.missingFontsDialog and ui.findFontsInFolder open the dialog for
agents; docs/control-protocol.md lists its fields.
- File › Package gives a font file whose name has no font extension
the extension that matches its data (.ttf, .otf or .ttc).
- vectorcraft-text adds set_app_font_dir, which system_font_dirs
reads, WantedFonts, which reads a font file's names as the font scan
does, is_font_file and is_suitcase. #762 split its face reader, which
now takes read budgets: file_face_names_within tries the suitcase
reader first, and reader_face_names_within applies the budgets to
each font. vectorcraft-format adds write_new_with.
Docs: docs/mcp.md, docs/control-protocol.md, ROADMAP.
A file's saved selections are untrusted: on load at most 25 are kept, names
are trimmed, capped at 255 characters and unique, and ids the document
doesn't have are dropped (after fix_next_id such an id would select whatever
object is drawn next). Save and Edit Selection cap names the same way. The
limit, the name cleanup and the default "Selection N" live on
SavedSelection, shared by the engine, the Save Selection dialog and the
Select menu's slot table. docs/mcp.md documents the select.save /
savedList / recall / editSaved commands; ROADMAP counts 13 stubbed menu items
and names what's still missing (Update Selection, the Layers panel menu).

- 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.

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.
UI: links.editOriginal, links.reveal, ui.placementOptionsDialog; Services.open_file
and pick_folder on the desktop.

- With Preferences > File Handling > Enable Background Save / Export on, File >
Save, Save As, Save a Copy and exports encode and write a snapshot of the
document on a worker thread; the call returns at once ({path, background}).
- 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.
- The host gives a thread-safe writer (Services::write_shared, atomic on the
desktop); without one (web, tests) everything runs at once as before.

- Format v3: optional gzip (Preferences > File Handling > Use Compression, or
document.save {compress}); compressed files open by their magic bytes, legacy
ones too.
- 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.

Older native files (.drawcraft or an older format version) open as
"<name> [Converted]" and Save asks for a .vectorcraft name instead of
overwriting them (preference appendConverted). Open Recent Files honours the
0-30 preference; empty slots are hidden (the native menu rebuilds when they,
saved views or User Defined libraries change). File > Document Color Mode is
one command, file.documentColorMode, converting through the colour settings;
choosing the current mode is not an edit, and object.convertDocumentColorMode
stays as an alias the command palette leaves out. New File > Show in Folder
(file.reveal; paths with spaces work on Windows). Native files store the view
they were saved with (Document.last_view, written at save time so it never
dirties the document) and reopen there.

A linked image (`ImageObject.link`, now a LinkInfo: absolute path, path relative to the document,
size, modification time, hash, page; old path strings still load) keeps a low-resolution preview
(`ImageBlob.proxy`, at most 256 px a side) that a native save writes in place of the pixels of
images only linked images show. Opening a native document reads the linked files again, looking
for each at its path, then relative to the document and by name in its folder: missing files
show their preview, modified ones are read again only with Update Links: Automatically.
`document.open` reports `missingLinks`, `modifiedLinks` and `updatedLinks`.
links.check reports each link's status, links.update reads modified files again and
links.relink points images at another file or at same-named files in a folder (each keeps its
bounds; one undo step). In the app, a document opened without its linked files asks about each
(Replace…, Ignore, Apply to All), then offers to update modified links when the preference asks.
The renderer caches previews apart from the file's pixels; the Eyedropper samples previews in
the object's pixel space.

Fill and stroke layers (and type characters' fill and stroke) carry an
overprint flag. object.setOverprint {fill?, stroke?, item?, ids?} sets it
(groups: their contents; type: its characters too; one undo step, none when
nothing changes) and attributes.info reads it back (null where mixed).
Overprint Preview and Separations Preview draw overprinting fills and strokes
with Multiply. The old Document.unknown["overprintBlack"] id list migrates to
the new flags on load; Overprint Black now sets the flags.

While a mask is edited, the Transparency panel and its commands act on the
masked object (Release leaves editing first). Mask commands and
transparency.set take ids and work without a selection; Make Opacity Mask
with one object adds an empty mask and enters editing. Opacity is 0..100 in
every command. transparency.info reports the panel's values with null for
mixed ones, shown blank. Saves and exports never include the editing layer
(Document::without_edit_modes; mask_edit is not serialized).
