The PDF writer defaulted to Convert Text to Outlines, so every glyph of
every page became a path: a text-heavy PDF grew several times larger on
export (a 7-page document went from 27 KB to 226 KB) and its text could
no longer be selected or searched. Illustrator's PDF presets embed font
subsets and keep live text; that is now the default too
(advanced.outlineText: false). Outlining stays available as an option,
fonts that can't be embedded still become outlines with a warning, and
printer's marks (page information) are drawn as shapes as before.

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.

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).

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.

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)

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.

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.

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.

Opening or placing a PDF or .ai with several pages or a password shows the
Import PDF / Place PDF dialog: a page preview with page navigation, Pages
(All or a range) when opening, Crop To (Bounding Box, Art, Crop, Trim, Bleed,
Media) and a password prompt for encrypted files.
- vectorcraft-pdf: ImportOptions.pages / crop / password, CropTo, info()
(pages, sizes, rotation, boxes); NeedsPassword / WrongPassword / BadPage
errors; images keyed by content so placed pages merge safely.
- document.open takes pages, page, cropTo (or crop) and password;
document.pdfInfo (query) lists pages and boxes, reports needsPassword and
renders a page thumbnail.
- file.place and file.place.info read only the page placed and take every
PDF box as crop (art, trim, bleed, media besides crop and bounding) and a
password; the UI's File > Place asks with the dialog when no page is given,
keeping Link, Template and the other place params.
- testkit::pdf writes hand-made PDFs with page boxes and RC4 encryption.

PdfSettings (serde, camelCase) is the Save PDF model: Standard, Compatibility
PDF 1.4-2.0, General (Preserve editing, Thumbnails, Fast web view, View after
saving, Create layers), Compression, Marks and Bleeds, Output, Advanced and
Security. PdfOptions = settings + pages, title and date.
document.exportPdf {path?, preset?, artboard?|artboards?|range?, standard?,
compatibility?, ...sections} -> {path|dataBase64, bytes, warnings} applies the
options over the preset (null keeps the preset's value); PDF/X, passwords,
PDF/A-2b at 2.0 and out-of-range values are refused; options accepted but not
applied yet come back as warnings. document.export {format: pdf} and
document.formats take and list the same options.
The Save PDF dialog (file.export.pdf, ui.savePdfDialog) has Preset,
Standard and Compatibility on top and a section list; it runs the export
before asking for a path, so bad options never open a save dialog.
