Changelog

[0.10.3] - 2026-05-28

Fixed

  • <Text style={{ width }}> inside a flex row now renders at the requested width instead of the parent row's full width. A 0.10.2 regression positioned such text using the requested width but sized its box to the row width; combined with textAlign: 'right' this pushed glyphs off the page (silent corruption — PDF bytes were deterministic so byte-hash snapshots passed). layout_text and the text branch of measure_node_height now honor a resolved fixed style.width, matching how layout_view and Image already behave

[0.10.2] - 2026-05-21

Fixed

  • Flex row children with percentage widths (e.g. width: '30%') are no longer double-resolved against their own already-resolved width — the percentage now correctly resolves against the parent's content width. Two children at 100% now shrink to 50/50 instead of collapsing
  • Grid containers that wrap over a page break now page-break by row (all columns moved to the next page together) instead of letting each cell trigger its own page break, which was scattering the columns across separate pages

Internal

  • layout_node now accepts a forced_outer_width: Option<f64> parameter so flex parents can hand the distributed width to the child without re-running style resolution

[0.10.1]

Skipped — npm-only patch.

[0.10.0] - 2026-05-19

Added

  • opacity now cascades to children — wrapping happens at the element level (single q ... Q covering own paint and child recursion) instead of the previous per-Rect wrap that left text inside opaque parents at full alpha. Nested opacities multiply via the PDF graphics-state stack
  • wordSpacing style property — user-facing, emits the PDF Tw operator. Stacks with text-align: justify's computed slack
  • Rounded clipping when overflow: hidden + borderRadius — clip path uses the rounded rectangle (m/c/h W n) instead of the rectangular re W n
  • boxShadow style property — offset filled rect behind the element, honors borderRadius, alpha routed through ExtGState
  • Page backgroundImage with backgroundOpacity / backgroundSize (fill/cover/contain) / backgroundPosition. XObjects dedupe across pages by URL
  • background style property accepting CSS linear and radial gradients. 2-stop gradients use a Type 2 (exponential) Shading; 3+ stops use a Type 3 (stitching) function. CSS angle convention (0deg = bottom→top, 180deg = top→bottom)

Internal

  • CI now runs a PDF size regression check (.github/scripts/check-pdf-size.sh) against a fixture that exercises all six new features. Fails on >5% byte growth over the committed baseline

[0.9.2] - 2026-04-28

Fixed

  • Redaction text-stripping now uses real per-CID glyph advances when locating regions, so partial-line redactions match the visible overlay precisely instead of dropping the surrounding text
  • CID font decoding in the redaction text extractor — handles Type0/CIDFontType2 streams correctly
  • PDF parsing in CID redaction is robust to binary font streams that previously confused the tokenizer
  • text_decoration is now part of the glyph style grouping key, so a line-through span inside an otherwise plain text node is no longer merged with its neighbors during PDF emission

[0.9.1] - 2026-04-06

Version bump only.

[0.9.0] - 2026-04-04

Added

  • certify_pdf() — apply a PKCS#7 digital signature to an existing PDF
  • redact_pdf() — redact regions from a PDF (removes underlying text)
  • redact_text() — find text by pattern and redact matching regions
  • find_text_regions() — find text regions in a PDF without redacting
  • merge_pdfs() — combine multiple PDFs into one
  • PKCS#1 private key auto-conversion: parse_pem_private_key() now accepts both PKCS#8 (BEGIN PRIVATE KEY) and PKCS#1 (BEGIN RSA PRIVATE KEY) formats, falling back automatically

Fixed

  • WASI timestamp: current_timestamp_secs() now uses std::time::SystemTime on wasm32-wasip1 targets instead of js_sys::Date (which is only available in browser WASM)

[0.8.3] - 2026-04-01

Added

  • SVG element opacity support: opacity, fill-opacity, and stroke-opacity attributes rendered via PDF ExtGState with inheritance through <g> groups

Fixed

  • Page node style now resolves against root style, so properties like fontFamily set on <Page style={...}> correctly inherit to child nodes

[0.8.2] - 2026-03-30

Fixed

  • Fix PDF serializer ignoring custom font weights — multiple weights for the same family (e.g. 200, 400, 700) now produce distinct font objects instead of collapsing to 400/700

[0.8.1] - 2026-03-30

Fixed

  • Fix Latin Extended character widths in standard font tables (Å, Ä, Ö, etc. no longer stack)
  • Fix page number placeholder width mismatch during layout ({{pageNumber}} measured at actual width)
  • Two-pass rendering: sentinel width now matches actual page count digits (1-9→"0", 10-99→"00", 100+→"000")

[0.8.0] - 2026-03-29

Added

  • AcroForm support: NodeKind::TextField, NodeKind::Checkbox, NodeKind::Dropdown, NodeKind::RadioButton
  • Form field layout functions and PDF AcroForm widget rendering
  • flattenForms option in render pipeline to convert form fields to static content
  • PDF/UA-1 compliance: structure tree (StructTreeRoot), tab order, role map, artifact tagging for headers/footers
  • pdf/tagged.rs: structure tree generation for tagged PDF
  • PDF/A compliance: sRGB output intent, XMP metadata with pdfaid:part/conformance, full font embedding mode
  • pdf/signing.rs: PKCS#7 detached digital signatures with ByteRange placeholder
  • Document.pdf_ua, Document.pdfa, Document.signature fields
  • Image.alt and Svg.alt emit /Alt entries in structure elements for PDF/UA

Fixed

  • extract_cn_from_cert_der() handles multi-byte DER lengths (CN > 127 bytes)
  • Checkbox appearance: checkmark instead of X; radio button: filled circle
  • flatten_forms renders placeholder text in grey when value is empty
  • Signing preserves existing AcroForm /NeedAppearances and /DA metadata
  • Unique signature field names (Signature1, Signature2) for double-signing
  • Form fields tagged as /Form role in structure tree (PDF/UA compliance)

Removed

  • SignatureConfig.page field (was accepted but silently ignored)

[0.7.13] - 2026-03-28

Added

  • chart/ module with shared types (ChartPrimitive, TextAnchor) and per-type builders (bar.rs, line.rs, pie.rs, area.rs, dot.rs)
  • Five NodeKind variants: BarChart, LineChart, PieChart, AreaChart, DotPlot
  • DrawCommand::Chart { primitives } with PDF rendering (Y-flip transform, arc sector bezier approximation, Helvetica labels)
  • ChartDataPoint, ChartSeries, DotPlotGroup data structs
  • 10 integration tests for chart rendering

[0.7.9] - 2026-03-17

Version bump only.

[0.7.8] - 2026-03-17

Added

  • barcode.rs: 1D barcode generation via barcoders crate (Code128, Code39, EAN13, EAN8, Codabar)
  • NodeKind::Barcode variant with data, format, width, height fields
  • layout_barcode() function (follows layout_qrcode pattern)
  • DrawCommand::Barcode with filled rectangle emission in PDF serializer
  • wasm_raw feature with C-ABI exports for non-JS WASM hosts (wasmtime, wasmer)

[0.7.6] - 2026-03-13

Added

  • Document.embedded_data field for embedding JSON as a FlateDecode-compressed PDF file attachment
  • PDF serializer emits EmbeddedFile stream + Names tree for forme-data.json

[0.7.3] - 2026-03-07

No changes.

No changes.

[0.7.1] - 2026-03-07

Added

  • Builtin Noto Sans Regular (400) and Bold (700) fonts via include_bytes!() (font/builtin.rs)
  • Document.default_style field for global style defaults (inherited by all children)
  • Automatic per-character font fallback to Noto Sans for chars not covered by the primary font

Changed

  • FontRegistry::new() now registers Noto Sans alongside standard PDF fonts
  • resolve_for_char() tries Noto Sans before Helvetica as last-resort fallback
  • segment_by_font() checks glyph coverage even for single-family text
  • char_width() uses per-char resolution when primary font lacks a glyph
