From 2aea7dcfeb64284882c23bd2d82e846e6e6f388f Mon Sep 17 00:00:00 2001 From: Raj Patel Date: Mon, 12 Oct 2026 00:31:36 -0600 Subject: [PATCH] M10: print from the web build through the browser's print dialog (gap 4) (#1243) * Gates: fix two clippy failures on main - ocr_ui: "Also recognize pages that already have text" used egui's own checkbox, which clippy.toml disallows (#1184 landed beside #1173); use widgets::checkbox like every other box. - camera_edges: Rust 1.97's manual_range_contains; the rewrite keeps the old answer for a NaN angle (false) with an is_finite check. Co-Authored-By: Claude Opus 5.5 Claude-Session: https://claude.ai/code/session_019ojKsSCHWk2AuyDTFMHCd7 * M10: print from the web build through the browser's print dialog (gap 4) The web build had no printer: spool::submit refuses on wasm, so Print could only download the print-ready PDF. Now its Print dialog offers "Browser's print dialog" (the default there), which reaches every printer the operating system knows. - web_print: PdfCraft draws the print-ready PDF's sheets itself (engine Exporter), one sheet a frame since wasm has no threads: 300 dpi up to 100 sheets, 200 up to 300, 150 up to 1,000, at most 64 MP a sheet and 1 GiB of PNGs a job. The PNGs become blob URLs and print from a hidden srcdoc iframe, one sheet per page, margin 0. - Chromium prints every page at the default @page size, so a sheet of the paper's size turned sideways is rotated 90 degrees CCW onto it (as drivers do); other sizes get named @page rules. - Copies, two-sided and colour are greyed out (the browser's dialog sets them). If print() is refused (e.g. a sandboxed frame), the print-ready PDF downloads instead, with the reason. - pdfcraft-print stays free of web APIs; six new strings in all 20 catalogs (ATTRIBUTION hashes refreshed); docs and parity updated, gap 4 closed. Verified in headless Chromium against a trunk build: three sheets at 300 dpi, the landscape sheet turned, no blank trailing page, and the download fallback. Firefox and Safari not yet tried.

A morphological paper estimate removes shadows and uneven light, and the trimmed ink is saved and reused like an image signature. Photos and images can also be dropped on the Image and Scan tabs. Photos keep the image-signature limits (#1124: a 4 MiB file, up to 32 megapixels decoded, scaled down to 4 megapixels), so a scan never processes more than 4 megapixels. `fill_sign_add` takes `scan` and `sensitivity`. Synthetic engine, UI and automation tests; checked by hand on real phone photos. Milestone and effort estimates unchanged. - **2026-10-12 (M10.5, hosted CI):** Integrated current main, including its date-table formatting and static-storage fixes. The Arabic synthetic drawing regression now checks the original serialized-output golden with and without the optional font face: the face-dependent FontName and FontFamily are checked separately and normalized only in the fixture. The hosted FreeBSD fingerprint is reproduced by those two metadata fields alone. Drawing bytes and all other fields retain the original golden; no printing behavior or readiness estimate changes. +- **2026-10-11 (M10, gap 4):** The web build prints. Its Print dialog offers "Browser's print dialog" (the default there), which reaches every printer the operating system knows. PdfCraft draws the print-ready PDF's sheets itself with its own renderer, a sheet a frame because the web build has no threads: 300 dpi up to 100 sheets, 200 up to 300, 150 up to 1,000, at most 64 megapixels a sheet and 1 GiB of pictures a job. It then prints them from a hidden iframe, one sheet per printed page with no margin. A landscape sheet among portrait ones is turned onto the paper, as a driver does, because Chromium prints every page at the default `@page` size. Copies, two-sided and colour are set in the browser's dialog, so the dialog greys them out. If the browser refuses to print (a sandboxed frame, for example), the print-ready PDF downloads instead. Verified in headless Chromium: the right sheets at 300 dpi, the landscape sheet turned, no blank trailing page, and the download fallback. Not yet tested in Firefox or Safari. Gap 4 closed; rank 1 is 65–120 → 50–90 h; other estimates unchanged. - **2026-10-11 (M10.5):** Extracted printer discovery, options and PDF submission into craft-libs/craft-print, shared with DesignCraft. Windows preserves composed sheet size and orientation without fitting into default margins; duplex binding edges are corrected. PdfCraft retains permission checks and imposition. Shared transport and local composition, engine, automation and UI coverage validate the boundary; native Windows CI passes, including paused-queue submission and cleanup; physical printer fidelity remains a hardware check. Rust 1.95 is required by the shared crate. No readiness percentage change. - **2026-10-11 (M10, #1028):** Recognize Text can read pages that already have text: "Also recognize pages that already have text" in the dialog (remembered with the other choices, and used by Recognize text in multiple files) and `skip_text_pages: false` on `ocr_recognize` and, newly, `ocr_recognize_files`. A picture on such a page becomes searchable, and a recognised word at least half covered by the page's own text (an earlier OCR layer included) is left out, so nothing is found twice; `ocr_recognize` reports how many were left out as `already_on_page`. Before, the option existed only for agents and added the page's text a second time. The default still skips pages with text. Synthetic tests (a picture of a sentence plus real text) cover the engine, the tool and the dialog, and fail with the filter turned off. Still missing: reading only the picture areas (the whole page is read, as for a scan). Separately, `recognize_text_makes_a_scanned_page_searchable` fails on main wherever the models are installed (the model reads "quick" as "auick"). Estimates unchanged. - **2026-10-11 (M2, page-label prefixes):** The page-label readers bound the total size of decoded prefixes. Each range decodes its own prefix, and ranges may share one prefix object, so a small file could ask for a copy per range: within the 200,000-entry tree limit, about 200 MiB of copies of one 1,024-byte prefix. Inspection and Organize now refuse a tree whose decoded prefixes pass 4 MiB in total (`MAX_PREFIX_TOTAL_BYTES`), before any label is made, as the other tree limits do; relabelling such a tree changes nothing. Synthetic tests share one 1,000-byte prefix across 5,000 ranges and keep exactly 4 MiB of prefixes readable.
