CMYK went to RGB through display sRGB: CMYK -> sRGB (clamped) -> working RGB.
Into a wider space (Wide Gamut RGB, the 1998 primaries) that clipped every
colour sRGB can't hold - CMYK cyan's red channel landed at 99 instead of 0 -
and the black-point compensation setting had no effect (moxcms leaves it
unimplemented). An ICC CMYK profile now converts directly into the RGB
profile: into its primaries with linear curves, where compensation is a
linear remap from the profile's black (found by sending black through the
profile and reading it back), then onto its own curves. The canvas uses the
same conversion into sRGB, so what shows is what an RGB export writes.
Checked against Ghostscript with the same profiles (relative colorimetric,
compensation on and off): exports into Wide Gamut RGB and the sRGB display
agree within 1 level in 255. The built-in CMYK spaces are unchanged (Generic
CMYK compensates in its own model).

A CMYK image with an /SMask, /Mask or colour key was handed to the
interpreter and stored as an RGB PNG, converted with hayro's own bundled
profile (Perceptual) rather than the working CMYK, so it showed 10-30 levels
lighter than other CMYK images and lost its ink amounts. It now keeps its
inks as other CMYK images do (#320), and its alpha becomes a greyscale
opacity mask. PDF export already writes that as a DeviceCMYK image under a
soft mask, so a round trip keeps the inks.

Document symbols placed inline in a run of type (beyond Illustrator; like
InDesign inline anchored objects): TextRun.inline holds the symbol, scale and
shift; the run is one U+FFFC laid out as a glyph sized to the art, centred on
the cap height. text.insertInline and Type > Insert Inline Symbol; editing
keeps the graphic whole; canvas, SVG (<use>) and PDF draw the art; Create
Outlines turns it into a symbol instance.
A `.ai` file's PDF part is what apps that don't read VectorCraft's native
document open. It had no PDF layers: hidden layers and sublayers were left
out of it and everything else was flat page content.
- `.ai` files (Save As, exports, the CLI) write PDF layers unless
`createLayers` is false (a PDF standard still decides for itself).
- createLayers writes sublayers too, as optional content groups listed
under their layer's in `/Order`, hidden ones off with their art.
- A layer's form gets a box round the whole page instead of its art's
bounds, which readers made a clipping group of, gathering a layer's art
and its sublayers' in one group.
- PDF import: art inside a group, clip or form that dissolves into its
parent keeps the layer it was drawn in, so sublayers nested in their
layer's content import as sublayers.
- Save PDF: "Create PDF layers from layers and sublayers" (ja, es, it,
pt-br, ru, zh-hans, zh-hant).
Hidden objects (not layers) still aren't in the PDF part.

- Type left unfinished when a layer's marked content ends, and a clip that closes in a later layer,
stay in their own layer (no stray "Page N" layer, no art moved to the next layer).
- Top-level layers stack as the pages mark them, so a layer whose art starts on a later page keeps its
place; layers marked with no art come in empty.
- A stroke written as each glyph's outline stroked, right after (or before) the type, becomes the type
object's stroke above (or below) its characters: the type stays one editable object.
- Spaces read from gaps wider than a space get their own tracking where even tracking would put the
glyphs after them more than a tenth of an em off (barcode digit groups); lines are measured to their
last visible glyph, so a wrapped line's trailing space no longer spreads into the tracking.
- Lines wrapped in a frame (each wrapped line ending in a space, one left edge, font, size and leading,
with an optional paragraph spacing) come back as one area type object, left aligned or justified,
only where laying it out breaks the lines exactly where the file does.

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.

Presentation Mode hides the menus and panels, had no Escape and was saved with the
preferences, so it came back on every restart with no way out. Escape now leaves it (as in
Illustrator), F from it goes back to Normal Screen Mode, and the screen mode is no longer
saved: the app always starts in Normal Screen Mode, and preferences saved in Presentation
Mode by older versions open normally. ui.inspect reports `screenMode` on its own.
Desktop file drags carry no pointer position or modifiers (winit 0.30 on Windows, macOS
and X11), so every drop on a window with a document open was taken for the middle of the
canvas and placed. Where the platform doesn't say, a dropped document (native, SVG, PDF,
.ai, EPS, DXF, EMF/WMF) now opens as a tab of its own and a picture or text is placed in
the middle of the view; pictures dropped together with documents are placed first, so the
last document opened is shown. The web, whose drag events give the position, keeps
Illustrator's choice: placed on the canvas, opened off it (the tab bar).
Illustrator's PDF-compatible part leaves out art outside the artboards (it lives in the
private data alone, which isn't read), so it can't open; importing a file with that
private data now says so in a note. Off-page art a PDF does draw already opens on the
pasteboard; a test keeps it so.

Type on a path could only be repositioned by Type on a Path Options, whose menu item sent
`{start: 0}`, so OK threw the text to the start of its path; nothing showed or dragged its
brackets. Now, as in Illustrator:
- Type on a path flows between a start and an end bracket (`TextKind::OnPath { end }`, None:
the end of the path or once round a closed one; `TextKind::path_span`). Flipping
(`TextObject::flip_on_path`) reverses the path keeping a closed path's first anchor and swaps
the brackets, so the type keeps its stretch of the path.
- Type on a Path Options gains Align to Path (ascender, descender, center, baseline) and
Spacing (glyphs spaced as if set that far above the path: closed up round the outside of
curves, opened up round the inside), laid out by the text engine.
- `type.pathOptions {start?, end?, flip?, effect?, alignToPath?, spacing?, ids?}` sets them in
one undo step; with none of them it queries. The menu item opens the dialog with the selected
type's Effect, Flip, Align to Path and Spacing (dropdowns for the choices) and leaves the
brackets alone, so OK as opened changes nothing.
- The Selection and Direct Selection tools show selected type on a path's path and its start,
centre and end brackets (`tools::pathtype`, with a bracket cursor): dragging the start or end
bracket sets where the type runs, dragging the centre bracket slides it along the path and,
across the path, flips it (Cmd/Ctrl held: it only slides). Each drag is one undo step.
- Arc-length measuring moved to `vectorcraft_geom::ArcPath` (layout, the tools and
`text.createInPath` share it). SVG export outlines path type whose end bracket, alignment or
spacing `<textPath>` can't express.
- docs/mcp.md documents the command and the drags; ROADMAP updated; dialog strings translated.

The import walks each page's content to learn which optional content
group each marked-content sequence belongs to, and stopped after 2,000,000
operators. Past that, art went to the page's "Page N" layer, visible and
printable, so a layer that was off (or didn't print) showed and printed;
an Illustrator drawing of about a million paths lost 6 of its 15 layers.
- The walk now reads up to 64 million operators a page (it reads about
15 million a second, twice as fast as the interpreter draws them; the
issue's 2.1-million-operator file imports in 3 s, a 10-million one in
15 s). Marked-content tags are kept as 64-bit hashes rather than byte
vectors, and at most 4 million a page, so the walk's memory stays
bounded on hostile input.
- When the walk is cut short (or the interpreter and the walk otherwise
part) and some group is off or doesn't print, art in marked content
whose group can't be told goes to a hidden, non-printing "Page N
(unsorted)" layer instead of the page's layer, and the warning says
so (and that the page was too large to read, when it was). Art drawn
past the limit inside a group already open stays in its group; art
outside any group stays on the page's layer. Files whose groups all
show and print keep the old fallback.
Tests (with the limit lowered): a hidden, non-printing group past the
limit lands on the hidden unsorted layer while the open group keeps its
art and the page's art stays shown; with every group shown, art goes to
the page's layer as before.

An object Illustrator writes as a fill of its outline left open and then a
stroke of it closed imported as two objects: a filled path and a separate
stroke-only path. A fill and a stroke of the same outline (equal once every
subpath is closed) now become one path with the fill and a live stroke
(width, cap, join, miter limit, dash, paint), taking the stroke's outline.
Layers: a group whose view state is off (/Usage /View /ViewState /OFF, with or
without an /AS view event) comes in as a hidden layer with its art, as groups
off in the default configuration already did. The configuration's /Order
nesting (inline or as its own object, labels skipped) makes sublayers, which
take their top-level layer's colour; nesting depth, entries and groups are
capped. Splitting a page's art by group is no longer quadratic, so thousands
of layers import quickly.
The 6D art pen (rotation-aware brushes) is a separate feature, now on the
ROADMAP gap list.

Opening a PDF whose fonts aren't installed keeps the text live in the fallback font (as
Illustrator substitutes and highlights missing fonts), and opening said so, but every export
then wrote the fallback font silently ("warnings": []), so a headless convert re-set the type
without a word.
- Exports that draw type now say so in their warnings, naming the missing families and the
fallback font: PDF (outlined or real text, also .ai and Save As), EPS, EMF/WMF, raster images
and SVG with outlined or embedded fonts. Live SVG text, DXF, text and native files name the
font itself and don't warn. Replacing the font (Find Font) clears it.
- The fonts a document uses (text.fonts' scope, Package's font list) come from one helper.
- textAs: outlines already keeps the glyphs the PDF draws (its embedded font program, installed
or not): now covered by a test with an embedded serif font that isn't installed, checked
against the installed font's and the fallback's outlines.
- docs/mcp.md and ROADMAP describe the warning.

A PDF's DeviceCMYK image opened as RGB (the interpreter's pixels as a PNG),
so every export wrote it as DeviceRGB or ICC RGB, silently. Images now keep
their CMYK samples, as CMYK colours already did:
- Model: CMYK images are blobs holding CMYK samples, a four-component JPEG
(Adobe's inverted samples) or a Deflate CMYK TIFF. vectorcraft-doc's cmyk
module reads their ink amounts (ImageBlob::is_cmyk, ::cmyk, capped at 64
megapixels) and writes the TIFF (ImageBlob::cmyk_tiff).
- PDF import: DeviceCMYK, CalCMYK and four-component ICC images keep their
samples. A JPEG with Decode [1 0 1 0 1 0 1 0] is kept byte for byte; any
other is decoded (8 or 16 bits, its Decode array applied) and stored as a
CMYK TIFF. Masked CMYK images and 1/2/4-bit ones open in RGB with a warning.
Placing a CMYK TIFF keeps it CMYK too.
- PDF export: CMYK images are written in CMYK (DeviceCMYK, or ICC-based with
the CMYK profile when colours are tagged: PDF/X-3, PDF/X-4, PDF/A). A CMYK
JPEG neither resampled nor recompressed passes through unchanged; others are
resampled in CMYK and compressed as ZIP or as a CMYK JPEG (jpeg-encoder,
which also replaces the ZIP fallback and its warning for images converted to
CMYK). Output conversion treats them like CMYK colours: Preserve Numbers and
PDF/X-1a keep their numbers, Convert to Destination converts them to another
CMYK profile or to RGB through a 17^4 lookup table (cms::CmykLut, now also
behind the renderer's ink table). A CMYK image that can't be decoded is
reported in the warnings.
- Canvas: CMYK images show through the working CMYK profile, as CMYK fills
do, and paint their own inks in ink planes (CMYK raster exports, CMYK
blending). SVG export writes TIFF images as PNG.
Illustrator's Output › No Conversion keeps colour data as it is

A PDF-compatible .ai paints the editor's page (an opaque white rectangle the
size of the page) before its first optional-content layer and outside every
layer. It came in as art: an extra "Page 1" layer with a page-sized white path
behind the artwork, which hid white art and gave SVG/PNG/PDF exports an
opaque background.
For pages with the editor's private data (the way the importer already tells
a .ai from a PDF), the first art outside every layer, painted before any
layer, is dropped when it is a plain fill-only rectangle in an opaque,
non-spot white, with normal blending, equal to the crop box (0.5 pt
tolerance). Plain PDFs keep such a rectangle as art (as the reference app
does when opening a PDF), and so does anything else: grey, smaller or larger
rectangles, strokes, translucency, white inks, fills over the layers.
The white-cover test the soft-mask reader used is now a shared helper.

Illustrator sets a paragraph's direction (Left-to-Right / Right-to-Left
Paragraph Direction in the Paragraph panel, with the Middle Eastern
options) and keeps its alignment buttons physical; it has no automatic
alignment toggle. So:
- ParaStyle.direction (None: from each paragraph's first strong
character, as before; written only when set), the Paragraph panel's two
direction buttons with Show Indic Options (original icons), and
text.setFormat {direction: "auto"|"leftToRight"|"rightToLeft"}. The
layout uses it as the base direction.
- The Automatic alignment check box is gone. Justify::Auto stays as the
start of the paragraph's direction, set on new type only (text.create,
the Type tools, with the mojikumi default in one new_type_para()):
TextObject::point is Left again, so importers (PDF, SVG, DXF, EMF) keep
their own alignment. The alignment buttons show what Auto resolves to.
- Bidi only where there is something right to left: plain paragraphs skip
the algorithm (no per-layout allocation), it runs once per paragraph
(shaping takes the paragraph's levels instead of recomputing them; path
type computed it four times), and the shaper keeps Han, Hiragana,
Katakana and Bopomofo in one segment (splitting at every change of
script cost Japanese text a shaper call per kana-kanji switch).
- Vertical type keeps its logical order, so its glyphs and lines are not
marked right to left (the caret no longer runs backwards down a column).
- PDF import puts Hebrew and Arabic, which PDFs (and VectorCraft's own
export) draw in visual order, back in logical order with the direction
that shows it as drawn; with bidi layout it came back mirrored.
- SVG import pins the direction SVG implies (left to right unless
direction: rtl); SVG export also outlines right-to-left paragraphs.
- Docs (development.md), ROADMAP (folded into the Type entry, Type core
row) and README updated; catalog rows for the new labels.

- Text in fonts that aren't installed comes in as live type in the fallback font again, named as
before (Helvetica-Bold → Helvetica Bold), not outlines plus pink copies on a non-printing layer.
- The installed face that matches a PDF font is decided once per font from its first comparable
glyph, not per glyph (loading up to 64 faces each time, and switching style mid-line).
- Kangxi radicals are unified only for text from Adobe's CID tables, not ToUnicode maps.
- A line is laid out again only when tracking changed it.
- CidText::of is tested on data that isn't a CID-keyed CFF (embedded fonts are untrusted).
- NOTICE: Adobe CMap resources (BSD-3-Clause) bundled through hayro-cmap.

Japanese PDFs and PDF-compatible .ai files often set text in CID fonts
with no ToUnicode map, in vertical columns, and in fonts the reader
doesn't have. They came in as outlines (or as the wrong characters).
- CID fonts without ToUnicode: the character comes from the font's CFF
charset through the standard CMaps (hayro's `embed-cmaps`); Kangxi
radicals that some generators map to are unified with their ideographs
(⿓ → 龍).
- A glyph becomes live type only when the installed font draws the same
glyph: compared by box with the font of the PDF's PostScript name, or
the closest style of its family (a variable font's named instances),
whose style the type then takes. Otherwise it keeps its outline.
- Vertical columns (WMode 1, glyphs with no horizontal advance) come back
as vertical type, letter spacing as tracking; a single upright glyph is
vertical type too. Horizontal lines get tracking from the glyph
positions the same way.
- Text in a font that isn't installed keeps its outlines (what prints),
with an editable copy in a substitute font, drawn pink, on a
non-printing layer named after the missing fonts (stroke-only glyphs
included).
- Marked content other than a layer's (spans with actual text,
artifacts) no longer ends a line of type: 篳篥・龍笛・笙 came back as
three objects when one character was in a span.
- Tests in tests_live_text.rs and tests_realtext.rs.

The font database made one style per font file, so a variable font
such as Figtree[wght].ttf listed only its default instance (Light).
Faces now also yield their fvar named instances, each a style of the
family named by its subfamily name (the default instance is the face
itself; unnamed or duplicate instances are left out; axes and
instances read are capped). The system font scan reads the fvar table
beside the name table, so installed instances are listed before the
file is loaded and found by name and by PostScript name.
An instance face carries its axis settings: skrifa draws its outlines
and reads its metrics and advances at that location, harfrust shapes
with a ShaperInstance, so layout, the canvas, Create Outlines and hit
testing all use the instance. PDF export embeds it through krilla's
Font::new_variable, SVG @font-face through subsetter's
subset_with_variations: both write a static font of that instance.
Tests build a small variable font in code (test_fonts, via
write-fonts; no font file is committed) and check listing, resolving,
glyphs and advances, PDF and SVG export and damaged fvar/gvar tables;
Bahnschrift and Segoe UI Variable are checked where installed.

A file with several artboards writes, on each page, the art of its
neighbours that reaches the page's box, shifted by its own artboard
spacing. Kept, those copies drew over the art of the page they came from
(a hologram over its card's stripes and title). With several pages, art
wholly outside a page's box now stays with the page it belongs to.

The path rebuilt through the glyphs ended where the last glyph ends, so
rounding in the spacing could push that glyph past the end, where type on

Apps write type on a path one glyph at a time, each placed and turned along the
curve. The importer joined glyphs into a line only while they kept the first
glyph's direction. Type on a gentle curve was flattened into straight lines, and
type on a tighter curve fell apart into one object per glyph.
A glyph that starts about where the previous one ends, turned a little from it
(under about 20°), now continues the line. A line whose baseline turned more than
about 3° becomes type on a path: its path is a smooth curve (Catmull-Rom as cubic
Béziers) through the glyphs' baseline origins and the end of the last glyph.
Spaces between words are measured along the last glyph. Straight type, rotated or
not, imports as before.
Test: "ARCHING" written glyph by glyph along an arc imports as one
type-on-a-path object with that text and a curved path; slightly rotated straight
type stays point type.

A document names its fonts by PostScript name, which the importer split at the
first hyphen into family and style. A family with hyphens in its name was never
found: "Rounded-X-Mplus-1c-black" became family "rounded", style
"x-mplus-1c-black", and the text fell back to another font. Common Japanese
families have hyphens in their names.
The system font scan now also indexes each installed face's PostScript name
(read from the same name table it already reads). The importer asks for the face
with that exact name first (`FontDb::by_postscript_name`) and splits the name only
when no installed face has it.
Test: installed faces are found by PostScript name, in any case.

- 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.

Every exporter (SVG, PDF, EPS, EMF/WMF, DXF) evaluated live objects with no
text outliner, so type inside an envelope was written undistorted. They now
share vectorcraft_effects::expand_live_deep, which outlines type per run in
each run's paint, as the canvas now does too (it used the first run's paint
for the whole line).

Rust 1.99's clippy adds chunks_exact_to_as_chunks, and cargo clippy

Opening, placing, pasting or importing a file, the font menus and MCP now find
the installed system fonts (Arial, Times New Roman...) in a fresh session, so a
file renders the same whatever happened earlier, and PDF import keeps the real
family names (Microsoft YaHei, not "Microsoft Ya Hei").
Root cause: FontDb only consulted the system font catalog, which stayed empty
until a CJK fallback or Character panel > Show System Fonts happened to scan
the font folders. Every lookup by family name (face, families, styles,
has_family) now waits for one cataloging scan per session: the app starts it
in the background, other processes run it on first use. The scan reads only
each file's table directory and name table (about 70 ms for 780 faces here,
instead of reading every font file whole), the catalog is indexed by family,
the family list is cached, and an installed style of a loaded family (a
bundled family also installed with more weights) loads when asked for.

compatibility "1.3" writes a %PDF-1.3 file (its XMP metadata says 1.3
too) without transparency: a copy of the document is flattened first
with flattenerPreset (stored with PDF presets; empty is High Resolution)
and the flattener options over it, see-through image pixels counting as
transparency and rasterized areas clipped to their regions so no soft
mask is needed. Page groups are left out and the writer refuses a file
that would still have transparency. PDF/X-1a and PDF/X-3 share this
path (their version is now PDF 1.3; 1.4 is still accepted and written
as 1.3), and with it the preset, the header and metadata code and the
transparency check. Passwords at PDF 1.3 encrypt with 40-bit RC4
(revision 2). The Save PDF dialog lists PDF 1.3 and picks the flattener
preset under Advanced.

Embed Page Thumbnails gives every page a /Thumb image: the page drawn on
white, 106 px on its long side, without the layers the page leaves out
(the engine draws them; vectorcraft_pdf::page_areas says what each page
shows; PDF/X files get grey ones). Optimize for Fast Web View writes a
linearised file: the objects are put in linearised order and numbering,
encrypted when a password asks (the encryption dictionary goes with the
catalog, PDF layers' groups too), then laid out with the linearization
dictionary, both cross-reference tables and the page offset and shared
object hint tables (the hint stream encrypted like any other). Their
"not applied yet" warnings are gone. Reading the objects back uses the
lexer of encrypt.rs (syntax.rs adds what rewriting needs).

Advanced > Overprint: Preserve (the default; document.exportPdf
advanced.overprint) writes each overprinting fill and stroke (an object's
own, a character's, a type object's) with a graphics state of /OP true
/op true /OPM 1 (/OPM 0 in PDF/A); Discard writes none. White ones knock out
when Document Setup's Discard White Overprint is on, as in print. Mask art
never overprints. File > Print's composite PDF honours Print > Advanced >
Overprints: Preserve the same way (separations keep multiplying plates).
Each overprinting fill or stroke is drawn as a form marked to overprint
(crates/pdf/src/forms.rs); after writing, its content starts by setting the
overprinting graphics state, and the PDF/X self-check runs on the result.
The engine's "overprint is not written to PDF yet" warning and print's
"overprints print as knockouts in composite output" warning are gone.

Create PDF layers from top-level layers (document.exportPdf createLayers, the
Save PDF dialog's General option) now writes an optional content group per
top-level layer (template layers are left out): named as the layer, off when
the layer is hidden, /PrintState /OFF when its Print option is off, locked
when it is locked, listed top first, with a print auto-state (not under a
standard). The file reopens with those layers.
The PDF writer has no optional content, so each layer is drawn as a form of
its own (no transparency group, so it draws as in place) starting with a mark;
after writing, the uses of the layers' forms are wrapped in /OC ... BDC/EMC
and the catalog gets /OCProperties (crates/pdf/src/forms.rs, through the
shared patch writer and the PDF syntax reader of encrypt.rs). PDF 1.4 and a
knockout page group write plain page content with a warning; the dialog greys
the option at 1.4. The "not written yet" warning is gone.

The pdf crate's PrintSettings gains advanced {printAsBitmap,
overprints: preserve|discard|simulate, flattenerPreset} and
color.profile, all defaulting so saved print_setup values still load.
Composite output discards overprints (no /OP) or simulates them as
Overprint Preview draws them; separations keep them. A printer profile
converts composite colours with the chosen intent (a CMYK one writes
device CMYK) and separations separate with a CMYK one. The engine
flattens transparency with the preset, or renders each printed region
as one image for Print as Bitmap, before PDF or PostScript layout.
The Print dialog's Advanced and Color Management sections show them.

View > Show Print Tiling (view.printTiling) draws the pages of the
document's print settings on the canvas, dashed and numbered, from
print.preview's own layout (print.tiling), so the canvas and the
printed job agree. The Print Tiling tool replaces the no-op tool: a
drag places the first page's imageable corner (print.tiling.set,
saved as print_setup.tileOrigin, one undo step); a double click on
the canvas or the tool button resets it. Tiles start at the origin
and extend to cover the art; the Print dialog shows the tool's
placement with a Reset button.

document.exportPdf {standard: pdfX1a|pdfX3|pdfX4} and the PDF/X presets now
write conforming files instead of being refused:
- every PDF/X file gets a /GTS_PDFX output intent (by default the CMYK
profile in effect, embedded), TrimBox, Trapped, GTS_PDFXVersion (and
GTS_PDFXConformance for X-1a), a title and dates; editing data,
passwords and, in X-1a/X-3, PDF layers are refused
- PDF/X-1a converts every colour and image to a CMYK destination,
untagged, with CMYK spot alternates; X-3 and X-4 tag colours with ICC
profiles
- X-1a and X-3 are written as PDF 1.3 and their transparency is flattened
first (High Resolution preset; images with see-through pixels count,
rasters stay opaque); X-4 keeps transparency, is PDF 1.6 at most and
names the standard in its XMP metadata
- the written file is checked against its standard (soft masks,
transparency groups, opacity, blend modes, RGB in X-1a, fonts not
embedded) and refused rather than mislabelled
- choosing a standard sets the latest compatibility it allows and turns
off what it forbids (engine and Save PDF dialog)

file.print {format: "postscript"} (the default for a .ps path) writes the
print job as Level 3 or 2 (level) PostScript instead of a PDF: DSC comments
with %%Pages the page count, one page per sheet with its paper size,
printer's marks in Registration, separations naming their ink (%%PlateColor)
with its halftone screen, a fixed flatness and film negatives. Transparency
is flattened first with flattenerPreset. The answer says which format was
written. In the app, a PostScript job is always saved, never sent to the
printer (the Print dialog's own options are unchanged).
The PDF print's layout is exposed as vectorcraft_pdf::plan (the PDF writer
uses it too); vectorcraft_eps::print draws its sheets with the EPS writer's
document walk, each sheet once however many copies print.

The Print dialog (Ctrl/Cmd+P) edits the document's print settings in the
sections General, Marks and Bleed, Output, Graphics, Color Management,
Advanced and Summary, with a preview of each printed page under the section
list (drag the art to move its placement). It drives print.setup,
print.preview and file.print; the preview pages now carry their transform,
printed area and trim box. Print sends the job's PDF to the chosen printer
through the new PrintService (lp on macOS/Linux, the shell print verb on
Windows, a hidden frame and the browser's print dialog on the web); without
one, or with PDF File, it saves the PDF. Done only keeps the settings.
UI commands file.print, print.printers and print.printerSetup.

With Convert Text to Outlines off (advanced.outlineText: false), type is
written as selectable, searchable text: each glyph in its font, embedded
as a subset with a ToUnicode map, where its outline would be (rotated,
scaled, skewed and on-path type too; gradients keep their place). Fonts
whose licence forbids embedding, or allows only whole fonts, fall back to
outlines with a warning; a subset threshold below 100% is accepted with a
warning. Laid-out glyphs now carry their glyph id and transform.

Save PDF > Output now applies: colours convert to a destination profile
(destination, or preserveNumbers keeping the numbers of colours already in
its model; grey stays grey; images and freeform gradient images convert
too; printer's marks don't). Profile inclusion writes ICC-based colour
spaces (CMYK with the destination's or the document's profile, RGB as sRGB,
grey), and transparency in CMYK output blends in the CMYK profile's space.
The output intent profile is embedded as the catalog's /GTS_PDFX output
intent with its condition, identifier and registry, and Trapped goes in
the document information (PDF/A keeps its own). A shared patch module
edits written PDFs (Lab spot alternates use it too).

- 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.

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.

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 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.

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).

Built-in presets are generated in code (VectorCraft Default, High
Quality Print, Press Quality, Smallest File Size and PDF/X-1a, X-3,
X-4, the latter listed as not supported yet) and read-only. Saved
presets live with the preferences (Prefs.pdf_presets) and work as
`preset` wherever PDF options are taken: document.exportPdf,
pdfSettings, export/serialize as PDF and .ai saves.
pdf.preset.list / save / delete / export / import manage them
(.vcpdfpresets files; opening one imports it). The Save PDF dialog's
Save Preset… saves its settings under a name; Edit > PDF Presets…
(ui.pdfPresetsDialog) lists the presets with each one's description and
differences from the default, with New…, Edit… (the Save PDF dialog as
a preset editor, ui.pdfPresetDialog), Delete, Import… and Export….
document.pdfSettings now lists what differs from the chosen preset.

Preserve Editing (on in the VectorCraft Default preset) embeds the
native document in the PDF as an embedded file with a hash of the pages
it was written with. document.open of a PDF, .ai or .ait restores it
exactly (restored: true) and falls back to importing the artwork, with a
first warning saying why, when the pages were changed elsewhere or the
data can't be read; SVG and PDF share that fallback and its warnings.
The legacy drawcraft payload name is read too. vectorcraft_pdf gains
editing(), ImportReport.native and PdfOptions.native.
document.save / file.saveAs / Save a Copy write .ai (format "ai" or an
.ai path): every artboard as a PDF that always carries the document and
takes the PDF options; a restored .ai keeps its path so Save writes .ai
again, and .ait templates open their document untitled. The desktop
save dialog lists the formats Save writes. Choosing a standard turns
Preserve Editing off (PDF/A refuses it), Export for Screens and PDFs of
some artboards leave it out with a warning.
