Conflicts: ROADMAP (main's guides and file-format rows, with the Affinity
items kept); fileio/load.rs (main's physical-size raster documents, kept
visible to the Affinity preview fallback).

#677 lets one image decode take up to 2 GB, so large print sheets open on the
desktop. wasm32 can address only 4 GB and aborts when an allocation fails, so
the web app keeps the decoder's default 512 MB and reports larger images as an
error instead.

The image decoder can't read a CMYK TIFF with an alpha channel at all
("color type Unknown(0)"); it is now read with the tiff crate, associated
alpha divided back out and the inks converted in the active colour settings.
And a 60 in sheet at 300 ppi (18000 x 6600 px) hit the decoder's 512 MB
default allocation limit; up to 2 GB is now allowed.

An image opened as a document took 1 px = 1 pt whatever its pHYs, JFIF or
EXIF resolution said, so a 300 ppi print file opened at four times its
physical size. It now opens the way Place already sizes it (pt_per_px):
at the resolution it declares, 72 ppi when it declares none.

Open and Place read Affinity documents natively (.af from Affinity 3,
.afdesign/.afphoto/.afpub from Affinity 1 and 2): layers and sublayers,
groups, artboards with their names and backgrounds, Publisher pages side
by side, curves with live corners, parametric shapes, compound shapes,
clipping by nesting, vector and pixel masks, solid and gradient fills,
strokes, fill layers, artistic and frame text, placed images (their
original JPEG/PNG), pixel layers, embedded documents as their cached
picture, opacity, visibility, locking and blend modes, at the document's
resolution in points. Unsupported content (effects, adjustments, brushes,
master pages, special shapes, Affinity-only blend modes...) is listed in
the import warning, one line per kind. A file whose native data can't be
read opens as its embedded preview with the reason, and that preview
cannot be placed or used as a template or library. Save never writes back
over the Affinity file and there is no Affinity export.
The document semantics were fitted to the thumbnails Affinity embeds in
176 public documents. `cargo xtask corpus --affinity` fetches 22 public
CC0/MIT/Apache-2.0 documents at pinned commits, sha256-verified; the new
engine test renders each and compares it with Affinity's own thumbnail
(0-4.4 of 255 mean difference, per-file ceilings). import_fuzz mutates a
synthetic native document's stream and container through open, render
and export; the fuzz crate gains a stream target.

Read only the indexed PNG thumbnail observed in version-12 Affinity containers. Bound and validate the PNG before decoding, warn about omitted native content, clear the source save target, and reject auxiliary imports that cannot display that warning. Add malformed-input, lifecycle, property and optional native-oracle tests plus a fuzz target. Editable native layers and Affinity export remain unsupported.
Switching to CMYK separates RGB greys through the CMYK profile into
four-colour greys and a rich black, as Illustrator does; only Gray
colours stay on the black plate. The command catalogue said "greys stay
greys", which read as if R = G = B colours went to K only.
- file.documentColorMode (and its alias) and document.open {colorMode}
take grays: "profile" (default, unchanged) | "black". With "black",
RGB greys with R = G = B convert to K only, K = their grey value (the
inks Edit Colors > Convert to Grayscale before the switch gives);
other colours convert as before. Swatches, tints, gradient stops and
pattern tiles follow the same rule.
- Pattern tiles are now converted with the rest of the document (they
kept RGB colours in a CMYK document before), as the command said.
- The command catalogue, docs/mcp.md and the ROADMAP say what happens to
Gray colours and RGB greys.
- Tests: the profile path (four-colour greys, rich black, pattern tiles,
Gray kept), grays: "black" over art, swatches, tints, gradients and
patterns, document.open, and the issue's file over MCP through a PDF
export and back.

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
(https://helpx.adobe.com/illustrator/using/pdf-options.html).

document.open and file.place read .eps files and PostScript by any name
(PostScript .ai opens as artwork, .ait as a new untitled document). An EPS
file VectorCraft wrote restores the document it carries (restored: true);
other files run through a small clean-room PostScript interpreter (paths,
colours and spot inks, gsave/grestore, concat, line state, bind def,
procedures, loops and dictionaries, clips, shadings, images through the
decoding filters, type as point type), and fall back to their TIFF preview
with a warning when the program can't be read. Operation, nesting, memory
and path budgets keep hostile files from hanging or exhausting memory.
The clipping-group nesting the metafile reader used moves to
vectorcraft_doc::clipnest, shared by both readers.

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.

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

pixels), embedProfiles (ICC profiles loaded from files that the document is
tagged with; opening installs them where missing) and pdfCompatible (native:

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.

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.

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
and focal points keep folding back as before.

New crates/cad (L3): a hand-written ASCII DXF writer. Layers become DXF
layers (hidden: off, locked, non-printing: not plotted), straight paths
LWPOLYLINE (POLYLINE before R14), curves cubic SPLINEs through every

document.export {format: dxf} and document.exportDxf; useArtboards
writes one drawing per artboard; selectedOnly (any export) writes the
selection in its layers. Export As lists DXF (then DXF Options,
ui.dxfOptionsDialog for agents, remembered between exports) and DWG
greyed out; document.formats lists DWG and PICT as unsupported with a
hint, and exporting or opening them answers with it.

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.

Save as Template suggests "<name> template.vctemplate" in the Templates folder
(the new templatesFolder preference; default Documents/VectorCraft Templates,
created by the desktop save panel) and never the source path. New from
Template is an engine command (file.newFromTemplate {path} or {name,
dataBase64}) that opens any readable file as a new Untitled-N document; in the
app, bytes from an agent go straight to the engine, otherwise the open dialog
starts in the Templates folder with template types first. .ait and template
files keep opening untitled.

Save As offers VectorCraft, VectorCraft Template, PDF, SVG and SVGZ and asks
for the chosen format's options before writing: SVG Options for SVG/SVGZ, the
Save PDF dialog for PDF (its OK finishes the save); on the web a Save As
dialog first names the file and picks the format. A document opened from or
saved as SVG/PDF remembers its format and options in one place
(DocState.format, save_options: the SVG options, or every Save PDF setting),
so Save writes it again; the result's warnings name what the format loses,
then the encoder's notes. Save a Copy writes "<name> copy.<ext>" and leaves
the path, title and modified state alone. Save is off for a clean saved
document, and Save as PDF... is in the File menu.
Engine: document.save, file.saveAs and file.saveCopy take {path?, format?,
options?, svg?} (SVG options also flat) and write linked images beside an
SVG; file.formatOptions reads a format's options. save_plan/save_with are the
one save path of every frontend, on the shared SVG encoder (one SVGZ path).
The template format is writable. Save panels get per-format filters, a folder
and a suggested name.

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.

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.

A PostScript file (a .ai saved in an older format or without PDF
compatibility, or an .eps, plain or with a binary header) is refused by any
name with a clear message instead of a parse error (there is no PostScript

DeviceCMYK and CMYK ICC colours import as CMYK and a file painted mostly in
CMYK opens as a CMYK document (with CMYK default swatches); DeviceGray
imports as Gray; Separation and DeviceN inks become global spot swatches
(their 100 % colour from the alternate space: CMYK, RGB, Gray or Lab) that
the art links to at its tint, /All links to Registration and process
colorants make CMYK. Shading stops keep their model and ink links the same
way. Inks mixed in one DeviceN colour, or spaces that can't be told apart,
import as RGB (with a warning for the mix).
document.open takes colorMode (rgb | cmyk) to open any file in that mode,
converted as file.documentColorMode does (its conversion is now shared).

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.

The editing data now sits in CDATA inside <metadata> with a hash of the
markup around that element (whitespace between tags and line endings
don't count). document.open restores the native document when the hash
matches (data written without a hash is trusted as before); when another
app changed the SVG, or the data can't be read, it imports the SVG and
says why in its warnings. vectorcraft_svg::editing reports the data and
whether it is intact; editing_data stays. Live effects, symbols and
patterns come back exactly; the import fuzz test now mutates saved SVGs
with editing data and hidden layers.

file.place {path | name+dataBase64, link, template, replace, at, rect, page, crop} places a
file as one undo step without touching the clipboard. Raster images come in at 100% of the
resolution their file declares (PNG pHYs, JFIF/EXIF, TIFF, BMP; 72 ppi otherwise), linked to
their path by default; SVG becomes one group with its embedded images; a PDF/.ai page or a
native document's artboard becomes one clipped group. The images, symbols, patterns and
swatches the art uses join the document (renamed on conflict). Replace keeps the replaced
object's stacking place and transform; Template puts the art on a new locked template layer
below the current one. file.place.info and image.info report size, ppi and colour mode.
File > Place picks a file and opens the Place dialog (Link, Template, Replace); the web picks
through the inbox. The Control bar shows Linked File/Embedded, the file name, colour mode and
ppi of the selected image.

svgz is a writable format with the SVG options (document.export,
serialize, save, Export for Screens): exactly the SVG export, gzipped.
SVGZ is recognised by its extension or the gzip magic bytes and opens,
places and pastes like SVG (clipboard.importSvg takes dataBase64 of SVG
or SVGZ); Export As SVG or Save As to a .svgz name writes it
compressed. Gzip lives in the svg crate (pure-Rust flate2, builds for
wasm) and unpacking stops at 512 MB.

document.export, serialize and save, and the Save As / Save a Copy UI
commands, take the SVG options flat or as svg: {…}: styling
(presentation, style, entities, css), outlineText, images (embed or
link; linked files are written next to the SVG), objectIds (layerNames,
minimal, unique), decimals 1–7, minify, responsive, useArtboards and
range "all" (one SVG per artboard), preserveEditing (the SVG reopens as
the full document) and metadata. Unknown keys are rejected and
document.formats lists every option with its default. Results carry the
SVG writer's warnings.
Save writes SVG to an .svg path and Save again reuses its options.
Export As SVG and Save As / Save a Copy to .svg open SVG Options (first
use: Internal CSS and Responsive, then the last-used choices) with a
read-only code view. Save a Copy no longer retargets the document.

One shared colour visitor (`colorcmds::Recolor`, used by Edit Colors, Recolor Artwork, the Blend
commands, the proxy Invert/Complement and Document Color Mode) maps solid colours, gradient stops
and text runs as before, and now also:
- gradient-mesh points (with fills); Blend grades meshes by their average and keeps their shading;
- embedded images' pixels (`includeImages?`, default on): the image becomes a recoloured copy under
a content key, the original stays for undo and other objects; linked images are left alone;
- the tiles of pattern fills and strokes (`includePatterns?`, default on): one recoloured copy per
pattern saved as a new pattern swatch ("Dots 2"), the original untouched.
Everything stays one undo step; only nodes that change are copied, in one walk of the tree.
- doc: `ImageBlob::map_rgb` (decode, map each distinct colour once, keep alpha, re-encode PNG),
`ImageBlob::content_key` (now also used by image import) and `ImageBlob::png`.
- `recolor.colors` lists mesh points and pattern tile colours too.
- patterncmds: `add_pattern` adds a pattern and its swatch (shared by Make Pattern and Save a Copy).
