The last four big web-vs-desktop gaps.
XREFs: XATTACH reads the picked drawing's bytes and registers them
name-keyed (the image/PDF-underlay pattern), pre-parses on the web
worker, and the commit merge produces the same xref block flow as
native. Opened drawings resolve xrefs from the registry (trailing-name
match) before cache build; unresolved references produce ONE warning
listing the names and the fix — drop the referenced files on the page
(drops and picker opens now register their bytes) and reopen or
XRELOAD. XRELOAD works off the registry on unsaved drawings too.
Data Link & Extraction: spreadsheet links read picked xlsx/csv bytes
(calamine from slices / CSV from string) through a session registry,
so preview, refresh, and table-insert work on web; extraction takes
external drawings via a multi-file picker parsed on the worker, and
outputs CSV/TXT/.dxex via download_bytes. The disabled 'Add folder'
button explains why.
ARCHIVE/ETRANSMIT: assembles the drawing plus registered images, PDF
underlays, and session plot tables into a deterministic ZIP (minimal
writer over flate2 — no new dependency) delivered as
{stem}_transmit.zip; skipped dependencies are reported by name.
Save/autosave off the UI thread: the parse worker gains a serialize
action (protocol v5) — the document is prepared once on the main
thread (clone, styles, dimension bake), then the DWG/DXF writer pass,
the dominant cost, runs on the worker; any worker failure falls back
to inline serialization with the identical shared implementation.
The save path also clears the dirty flag only when the tab didn't
change mid-write, and the runtime-fields sidecar now carries
graphic_data, fixing a pre-existing loss of raw DWG round-trip bytes
on web-opened documents.
Printer enumeration used EnumPrinters level 4 only, which is served
from the local registry cache and misses Win11 per-user network
printers; an empty result now retries with level 2 (spooler RPC) and
merges the resolved default. The dialog's 'System default printer'
used to delegate to the shell print verb — the default PDF handler's
own printer choice, not the system default; it now resolves
GetDefaultPrinterW and dispatches printto naming that printer
explicitly. Every dispatch probes OpenPrinterW first, so a printer
that vanished between listing and printing produces a clear error
instead of ShellExecute's silent nothing, and all SE_ERR_* codes carry
readable reasons.
Legacy CTB: picking an unparseable table used to swallow the failure
(.ok()) — the user saw nothing at all. Load errors now reach the
command line, the picker accepts .stb alongside .ctb (the container
gains the STBVER1 header; .stb application errors state the actual
reason), and a table loaded from anywhere is copied into the user's
plot-styles folder so it persists in the dialog, matching AutoCAD.
Buffer parsing for both EnumPrinters layouts is unit-tested; the
missing-printer path was exercised against the real spooler (existence
probe only, no job).
STLOUT/STEPOUT wrote via std::fs and IMPORTOBJ read via std::fs, all
of which fail on wasm32. The export pickers now mirror the PDF path
(pick_*_owned returns a name-only PathBuf; the browser download names
the file) and the write tail swaps fs::write for sys::download_bytes.
OBJ import reads the picked file's bytes directly, like the web open
picker.
Opening by drag-and-drop was dead on the web build: winit never emits
FileDropped there. A wasm-gated io::web_drop module installs DOM
dragover/drop listeners, filters .dwg/.dxf, reads the File bytes
async, and queues them; the existing 50 ms PollWebControl tick drains
the queue into the same open path the picker uses (progress overlay,
recovery, OPFS recent cache).
Also floors the model-space plot sheet: extents smaller than 10 mm
(or the 0x0 paper a fresh unsaved drawing carries) now fall back to
the standard sheet instead of producing a ~3 pt page.
- pdf_export: drop the stale wasm32 gates (printpdf 0.9.1 compiles for
wasm; the memchr/lopdf incompatibility is gone with memchr 2.8.3).
Rendering is portable via render_pdf_bytes; only persistence differs:
atomic temp-file write on desktop, browser download on the web.
pick_pdf_path_owned on wasm returns a virtual path so the existing
message flow works unchanged.
- printpdf moves from the native-only dependency table to the shared one.
- print_to_printer: preview_page_pdf / preview_pages_pdf render the same
bytes and open them in a browser tab on the web (the browser's print
dialog takes over); desktop keeps the temp-PDF + OS-viewer flow.
- sys: open_bytes_in_new_tab (blob URL, popup-blocked falls back to a
download).
- New PlotQuality preset caps embedded raster resolution (High = native,
Normal = 300 DPI, Low = 150 DPI effective); vector output is untouched.
The image resource cache keys on the post-resample dims so one pixels
Arc placed at different effective DPIs embeds per-placement XObjects.
Include decoded IMAGE/OLE content in the shared PDF plotting path,
with clipping, transforms, transparency, draw order, and resource reuse.
Use named page content for export and printing.
Fixes#1266
Populate the plot-dialog printer list from the Windows spooler cache.
Validate record counts and UTF-16 name bounds before reading the buffer.
