Changelog

Removed

• @inkoxide/render no longer ships MIGRATING.md, and the benchmarks measure Inkoxide alone.

Added

• Rendering in the browser. @inkoxide/render/browser renders the same templates with the engine as WebAssembly, in a Web Worker, to the same PDF bytes as Node (but for the last digits of SVG marker angles): renderToBuffer and renderToBlob, whose signal or timeoutMs stops a render, generate, clearCaches, and the React helpers usePdf, <PdfDownloadLink> and <PdfViewer>. It needs no cross-origin isolation, and a Content Security Policy needs only 'wasm-unsafe-eval'. The engine is about 1.2 MB to download with brotli; a bundled font downloads when a document first draws with it (Noto Sans, the fallback, only for a character Inter lacks), and a language's hyphenation patterns when a document first hyphenates text in it. See GUIDE.md, "In the browser".
• @inkoxide/wasm, the engine as WebAssembly, with the functions of inkoxide, and init, clearCaches and loadHyphenation; its render fetches the hyphenation patterns and the deferredFonts a document needs. It is released with the other packages, at their version.
• @inkoxide/tailwind has a browser entry, chosen through the browser export condition, with Tailwind's theme bundled.
• Rust: inkoxide::clear_caches(); the cargo features msgpack, for InputFormat::MessagePack, and embedded-hyphenation, for the built-in hyphenation patterns, both on by default; without the latter, HyphenationStore::register_builtin gives a language's patterns (builtin_hyphenation_file names its file). RenderOptions::deferred_fonts lists declared fonts that may be missing until a render needs one. A render that needs what it was not given fails with InkoxideError::NotLoaded (NOT_LOADED), naming it.
• A text node with hyphenate on and no lang (nor meta.lang) logs a warning, and the warnings of an @inkoxide/render result say so, since such text is not hyphenated.

Changed

• @inkoxide/react validates trees in development with code generated from the schema, which compiles nothing at run time: it no longer depends on ajv.
• The engine matches words against the built-in hyphenation patterns itself, with hypher's patterns and algorithm, so that they can also come at run time; it hyphenates as before.

Fixed

• The READMEs, GUIDE.md, MIGRATING.md, docs/API.md, docs/SCHEMA.md, docs/CLIENT_INTEGRATION.md, the schema README and descriptions, and the --png-dir help of the CLI no longer contradict the code. They now say that a word wider than its line breaks between any two characters, and that [word] from a hyphenation callback keeps a word from being hyphenated, not from breaking.

Security

• The work budget of a COLR colour glyph also counts the paint tables its paint graph reaches, each as often as it is reached, before the glyph is painted: past 10000 the glyph draws without colour, whether or not those paints draw anything. So does a glyph whose paint graph has a cycle or nests more than 64 deep, which the COLR specification does not allow.

Fixed

• An SVG without width, height or viewBox is laid out at the size of what it draws without its text, the size it is drawn at, instead of a box sized by its text that stretched the drawing and clipped the text.
• alignItems and alignSelf: 'baseline' align the first baselines of the items' text, as in CSS, instead of their bottom edges.
• A table nested in a row split across pages continues below the repeated header rows of the table around it, and repeats its own header rows below them; its first row on each new page was hidden under the outer header.
• Fixed elements in the body are painted in paint order, by zIndex then document order, as without fixed; they were painted over everything else in the flow. A fixed element inside an element that is not painted on a page (display: none, opacity: 0, pages) is not painted there either.
• Encryption permissions with an owner password equal to the user password are INVALID_VALUE at options.encryption.permissions, since the user password would lift them.
• A second checked radio button in a group is INVALID_VALUE, and radio buttons of one value share an on state in encrypted files too, so a radio repeated on every page turns on and off as one, as in a plain file.
• A text, select or list field whose value or options have a character its font lacks is INVALID_VALUE, instead of the character being left out silently. Field text is drawn with its own font only, without fallback fonts, shaping or right-to-left ordering, and the docs now say so.
• @inkoxide/render and inkoxide reject a render option of the wrong type (threads: '4', pdfA: 5, a permission that is not a boolean) with ENGINE_REJECTED / INVALID_ARGUMENT at its path instead of INTERNAL; localImages without root is a RenderError; and option errors no longer name <Document>. Options that are not an object now fail.
• The guide says what happens after a font fails to load (it is dropped, and later renders fall back from it), and that only faces of the same weight and style clash on their family name.
• w-screen, h-screen, min-h-screen and the other *-screen sizing classes are listed and tested as supported.
• lineHeight takes lengths and percentages ('14pt'), letterSpacing in em reads the same in a style and a class, and props an element would ignore (<Page wrap={false}>, href on a Cell or Header, <Document pdfVersion>, hyphenationPenalty, className on an SVG shape) now throw a TemplateError; errors inside a render prop keep the components around it in their stack.
• An emoji drawn from emojiImages in a run with verticalAlign: 'super' or 'sub' is raised or lowered with the run's text; it stayed on the line's baseline.
• The limit of 4096 colour glyphs per render counts only glyphs drawn in colour, not every glyph of a colour font. Glyphs of a bitmap-only colour font that are not drawn in colour (past the limits, or without colour, such as its space) still copy and search as their text instead of disappearing.
• COLR layers in the foreground colour take the run's color, as in browsers, instead of always drawing black. In the text of SVG images they still draw black.
• A page with a side under 3 points fails a PDF/A render with PDFA_CONFLICT at the page's size, at every level; such a file was not PDF/A.
• The engine and the JSON Schema agree on more values: the schema rejects negative sizes, gaps, padding and grid tracks as the engine does, integers may be written as 400.0, options: [] is INVALID_VALUE on every field, and percentages and fr sizes are bounded as written ("10000.0001%" is OUT_OF_RANGE).

Changed

• A host entry in remoteImages.allow (cdn.example.com, *.example.com) allows only port 443, unless it names a port (cdn.example.com:8443). Host entries used to allow any port; URL entries already matched it.
• Encrypted PDFs give each font the widths of all its glyphs (/DW and /W), not only those of the glyphs used, so the widths no longer depend on the text. This adds up to about 5 bytes a glyph per font (some 15 KB for a Latin font); unencrypted output is unchanged.

Fixed

• A colour glyph drawn as an image, in page text and in SVG text, extracts as the text of its own cluster, not the text it was first shaped with.
• Images are told apart by their bytes, not only by their hash: two different images whose hashes are equal are drawn as two images, and each is checked for transparency on its own under PDF/A-1b. Font subsets kept across renders are keyed by the font's SHA-256.
• A render waiting for an emoji image another render is already fetching stops at its own remoteImages.timeoutMs, and the download goes on for the other renders.
• SECURITY.md and the API docs say which form field state stays readable in encrypted files: checkbox states, the position of the chosen radio button, and the positions of a list box's selected and first visible options. Field values and options are encrypted.

Security

• The tables of a document are limited to 1000000 grid slots in all (rows times columns, however the cells span them); more is OUT_OF_RANGE at the table's rows. Checking a table's rows takes time in proportion to them.
• fallbackFonts holds at most 256 ids; a longer list is OUT_OF_RANGE. A font listed more than once is tried once, where it is first listed.
• A form field name that breaks the name rules is reported once as INVALID_VALUE and is not checked further against other fields' names and groups.
• SVG text counts the properties each span inherits toward the SVG limits, as shapes do, and spans that inherit one font-family share it; an SVG over a limit fails with INVALID_IMAGE. The image cache counts the text read from an SVG in the size of its entry.
• textLength in SVG text takes time in proportion to the characters inside it, however many spans set one.
• A wavy text decoration draws its waves only where the page shows them, and at most 16 half waves per glyph: a wider piece of text gets longer waves.
• Headers, footers and fixed nodes count the alt text of images in text, the text of colour glyphs and link targets in the estimate of what they repeat on every page.

Added

• Floats: float: 'left' | 'right' and clear: 'left' | 'right' | 'both' (Tailwind float-left, float-right, clear-*) on the children of a column View, a Page or a Cell. Text after a float wraps beside it, line by line; a box after it is narrowed to the room beside it, or moved below it; the parent grows to hold its floats; and a float moves to the next page with the lines beside it. A float taller than a page is sliced. debug on a paragraph beside a float shows its narrower line boxes.
• Encryption: user and owner passwords and permissions (printing at low or high resolution, modifying, copying, annotating, filling forms, content accessibility, document assembly), with AES-256 (PDF 2.0, revision 6). RenderOptions::encryption with Encryption, Permissions and Printing in Rust, encryption: { userPassword, ownerPassword, permissions } in the Node binding and in @inkoxide/render, and <Document userPassword ownerPassword permissions>, which the option replaces. Passwords are printable ASCII up to 127 bytes, never part of the document tree, and never shown in errors or Debug output; in Node, a password that is not a string is INVALID_ARGUMENT at its path before the engine sees it. Output stays deterministic: the keys are derived from the document and the passwords. Radio buttons name their states by position in an encrypted file, with their values in /Opt, so the values are encrypted too, and the subset tags of font names are keyed by the file's keys. Encryption with PDF/A is INVALID_VALUE at options.encryption in Rust and INVALID_ARGUMENT in Node. SECURITY.md lists what encryption does not protect.
• PDF/A-1b and PDF/A-3b, next to PDF/A-2b: RenderOptions::pdf_a_level with PdfALevel in Rust (with_pdf_a_level; PdfALevel::ALL lists the levels), pdfA: '1b' | '2b' | '3b' in the Node binding and in @inkoxide/render (true is still PDF/A-2b), --pdf-a=LEVEL in the CLI (--pdf-a alone is still PDF/A-2b, also before the document), and <Document conformance> ('PDF/A-1b', 'PDF/A-2b', 'PDF/A-3b', or the part alone), which the pdfA option overrides. The a and u levels, which need tagged PDF, are a TEMPLATE_ERROR.
• PDF/A-1b has no transparency: a render at 1b fails with the new code PDFA_CONFLICT at the path of the first colour with alpha below 1, opacity between 0 and 1, debug, image (or background image) with an alpha channel, or SVG drawn with opacity, a mask or a blend mode (ENGINE_REJECTED with the component in @inkoxide/render). validate does not know the level and does not report it. A PDF/A-1b file also keeps within the limits of PDF/A-1 (numbers, strings, arrays, dictionaries, graphics state nesting) or fails with PDF_ERROR.
• textWrap: 'pretty' (Tailwind text-pretty) breaks a paragraph's lines over the whole paragraph for even lines (Knuth and Plass's total fit), with fewer hyphens; justified pretty lines may also shrink their spaces by up to a third. It is inherited. 'wrap', the default, keeps first fit and the same output; 'balance' is reserved. text-wrap maps to wrap and text-nowrap to whiteSpace: 'nowrap'.
• Superscripts and subscripts: verticalAlign: 'super' or 'sub' on a Text (the Tailwind classes align-super and align-sub) raises or lowers its baseline by the font's own superscript and subscript offsets, and the line grows to fit it. verticalAlign stays top, middle or bottom on a Cell.
• OpenType features: fontFeatureSettings as a CSS string ("'tnum' 1, 'liga' off"), a list of tags or an object of tags to values or switches, and fontVariantNumeric ('tabular-nums slashed-zero'); in Tailwind, font-features-[…], tabular-nums, oldstyle-nums, slashed-zero, ordinal, diagonal-fractions and the other numeric classes. Both are inherited. A run takes at most 32 features, with values up to 65535, and a document at most 64 different sets of them (OUT_OF_RANGE). @inkoxide/style exports parseFontFeatureSettings, parseFontVariantNumeric and RUN_ALIGNS.
• debug on a Text outlines the paragraph line by line: each line box, its baseline, and the glyphs of every run on the line, so nested Text and Link elements show where their words landed.
• <Marker> in <Svg>: a shape drawn at the start, middle or end vertices of a path, line or poly shape, referenced with the new markerStart, markerMid and markerEnd props. It takes viewBox, refX, refY, markerWidth, markerHeight, orient and markerUnits. Marker and MarkerProps are exported.
• fr, the radius of the focal circle, on RadialGradient.
• The <Canvas> painter clips and paints gradients: clip(rule?) clips what follows to the current path until restore(), and linearGradient(x1, y1, x2, y2) and radialGradient(x1, y1, r1, x2, y2, r2) return a CanvasGradient (exported as a type) that takes colour stops with stop(offset, color, opacity?) and paints in place of a colour. miterLimit(n) sets how far mitred joins reach.
• Text in the <Canvas> painter: font(name, size?) (a registered font id, a family name, or one of pdfkit's standard names such as Helvetica-Bold, which picks the canvas's family in that weight and style), fontSize(n) (12 by default) and text(str, x, y, options?), which draws one line with the fill colour or gradient, its top at y by default. The options are width with align (justify, as in pdfkit, is left: a line does not wrap), baseline, characterSpacing, wordSpacing, underline, strike, fill (whether to fill the text, true by default) and stroke; CanvasTextOptions is exported. A line break in the text is an error.
• Text in SVG images: <text>, its <tspan>s and <a>s are drawn as PDF text with the document's fonts, so it can be selected, searched and copied, in SVG files and in SVGs nested in them. Each span's font is the declared font that matches its font-family, font-weight and font-style (as CSS matches them), with the document's fallback fonts for characters it lacks. Positions (x, y, dx, dy, rotate), text-anchor, dominant-baseline, alignment-baseline, baseline-shift, letter-spacing, word-spacing, text-decoration, textLength, lengthAdjust, xml:space, style sheets, and fills and strokes with gradients and patterns work, also in clip paths, masks, patterns, markers and use copies, whatever an author style sheet says about the paths of the SVG. Colour emoji fonts draw in colour there, and emoji the document maps to images are those images, as in other text. Text on a path, vertical text and text that an XML entity expands to fail with INVALID_IMAGE, as all SVG text did. An SVG without a size takes it from what it draws without its text, so the same with any fonts. An SVG with text in a document that declares no fonts fails validation with INVALID_IMAGE, and an SVG may hold up to 1,000,000 characters of text, counting every copy.
• <Text> and <Tspan> in <Svg>: a Text inside an <Svg> (or its G, Defs, ClipPath or Marker) is SVG text, with x, y, dx, dy, rotate, textAnchor, dominantBaseline, letterSpacing, wordSpacing, textDecoration, textLength, lengthAdjust, direction and the SVG paint props; a Tspan inside it is a span, which also takes baselineShift and alignmentBaseline. Its font comes from fontFamily, fontWeight and fontStyle on it or around it, and from the text style around the drawing, matched against the registered fonts like other text, and declared in the document. Tspan, SvgTextProps and TspanProps are exported; SvgPresentation gains the font props, textAnchor, dominantBaseline and visibility.
• Background images: <ImageBackground src fit>, a View with an image behind its children, and backgroundImage on a box node of the document (src or data, fit, objectPosition). The image fills the padding box, over the background colour and under the borders, clipped to it and rounded by borderRadius; a box split across pages is sliced with its image, like its background colour. src takes every form <Image src> takes, and fit, objectFit, objectPosition and the object-* classes place it as on an Image.
• Colour emoji from fonts. Glyphs in a font's COLR table (versions 0 and 1) and PNG bitmaps in CBDT or sbix are drawn in colour, as images that copy and search as their text (ActualText). Register an emoji font, such as Noto Color Emoji, and list it in fallbackFonts: an emoji goes to the first colour fallback font that has it. A font with colour bitmaps and no outlines now registers; it is never embedded and cannot be a form field's font. A colour glyph that takes over 10 000 drawing steps, or past the first 4096 of a render or the first 32 MB of colour glyph images, draws without colour. Under PDF/A-1b, which forbids transparency, a colour glyph that needs it (a bitmap with an alpha channel, a layer with an opacity) fails the render with PDFA_CONFLICT at its run, as an emoji image does at its emojiImages key, or at the src of an SVG whose text has it.
• Emoji from images: Font.registerEmojiSource({ url, format, withVariationSelectors }) or { builder } draws the emoji of every Text from an image set, through the document's new emojiImages (emoji sequence → image id). The images load like <Image src> (URLs allowed by remoteImages, kept between renders); an emoji image is 1em high with its aspect ratio and copies as the emoji. An emoji whose image cannot be loaded, or is not an image the engine can draw, is drawn by the fonts with a warning, and a ZWJ sequence without an image uses those of its parts. EmojiSource is exported.
• Images in text: an <Image> inside a <Text> (and image on a document's text run) sits in the line, as wide and high as asked in points or em (1em high by default, keeping its aspect ratio), placed by verticalAlign (baseline, middle, text-top, text-bottom, top, bottom, super, sub or points; align-text-top and align-text-bottom in Tailwind), with alt as the text it copies as. Lines break around it like around a character.
• Groups of form fields: a dot in a field name puts the field in a group, as in PDF's own field names. address.street and address.city are the fields street and city of the group address; a name has at most 32 parts, so groups nest up to 31 deep. The PDF holds them as a field tree, which viewers show and export by their full names.
• List boxes: a form field of kind: "list" shows several of its options at once (four rows without a height) and scrolls to the first selected one. With multiSelect, value is an array and several options can be selected.
• Formats on text fields: format shows a number (decimals, separators, negative style, currency), a percent, a date or a time (with a pattern such as dd/mm/yyyy), a postal code, a phone number or a social security number, and viewers format what the user types with the standard form scripts. PDF/A output keeps the formatted text and value but leaves the scripts out, as PDF/A requires.
• Text notes: a note node is a sticky-note icon that viewers open to show its text, with an author, a colour and whether it starts open. It takes no space; the icon sits at the top-left corner of its box, keeps its size at any zoom and stays upright under a transform. It has an appearance stream, so it prints and passes PDF/A-2b. A note can also be part of a line of text (note on a text run): it takes no room there, and its icon hangs from the top of the line where it is. Line breaking keeps it with the word before it.
• <FieldSet name> in @inkoxide/render: a View, with its props and render, whose name goes in front of the names of the fields inside it, at any depth (address.street); sets nest.
• <List> in @inkoxide/render, a list box, with multiSelect and an array value; Field takes kind="list". Select and List take their choices as options or select, and TextInput is another name for TextField.
• format on TextField in @inkoxide/render, with the readable keys of the schema, or param, nDec, sepComma, negStyle and currencyPrepend; the type TextFormat is exported. A number or percent format with any of those keys defaults to no decimals and no thousands separator; on a time, param is one of four styles, 0 to 3; zip4 is zipPlus4.
• <Note> in @inkoxide/render: a text note, with its text as children, author, open, and its backgroundColor as its colour. Inside a <Text>, it is part of the line.

Changed

• Emoji sequences (flags, keycaps, skin tones, tag sequences and ZWJ sequences such as 👩‍💻) stay in one font, so the font's ligature forms: their selectors, joiners and modifiers could go to another font than their base, which drew them as separate glyphs.
• Strokes with mitred joins in a <Canvas> have a miter limit of 10, PDF's default, as in pdfkit; they had SVG's 4, so joins sharper than about 29 degrees (down to about 11) are now mitred instead of bevelled. miterLimit(4) gives the old joins.
• In SVG images, em and ex lengths and font-size keywords are relative to a font size of 16 where nothing sets one, as in browsers; it was 12.
• Font family names match ignoring ASCII case, as in CSS: fontFamily: 'inter' picks Inter instead of falling back with a warning. Font.register refuses a family that differs from a registered or bundled one only in case, for the same weight and style.

Security

• The text of SVG images is bounded as the rest of the SVG is: what replaces it for the SVG conversion counts toward the SVG limits as it is drawn, before it is written, and validation checks it as a render does, so an SVG over a limit fails validation with INVALID_IMAGE. The text nodes of an SVG text count as elements. Reading, laying out and drawing SVG text takes time in proportion to it.
• Field options and values are limited to 1000 options of at most 1000 characters each, and a value of at most 8000 characters. Longer ones are INVALID_VALUE.

Security

• Text is held to a limit on the glyphs shaping makes beyond one per byte of text: about 4 million over a render. Over it, the render fails with FONT_ERROR naming the font. Text shapes to about one glyph per byte or fewer, but a font whose layout tables substitute one glyph with thousands made a few kilobytes of text take gigabytes of memory. Those glyphs also count toward the limit on what is painted on every page, which counted characters only.

Fixed

• A form field taller than a page is one widget, on the page it starts on: it was a widget on every page it was sliced across, each embedding the field's editing glyphs again, so a single field could make tens of thousands of widgets and take seconds to render. The glyphs for editing a text or select field are now added once per font. Found by the render_tree fuzz target.

Fixed

• A CFF font with a number in its Top, Font or Private DICT that overflows a 32-bit float (or beyond 10³⁰) is rejected with FONT_ERROR when it is registered. Registering it panicked in the font subsetter: a panic in Rust, an INTERNAL error in Node. Found by the register_font fuzz target.

Changed

• The limit on what is painted on every page is about 64 MB instead of 256 MB: a document just under 256 MB made a PDF that size and took seconds to render.

Security

• What is painted on every page (headers, footers, overlays, fixed elements and repeated table header rows) is held to a limit of about 256 MB over the whole document, estimated before anything is painted; a document over it fails with LAYOUT_ERROR. Repeated on every one of thousands of pages, a few kilobytes of content (a fixed element taller than its page, links on every line) made a PDF of several gigabytes. Elements shown on some pages only (pages) count for those pages. Found by the render_tree fuzz target.

Added

• Document metadata producer, pageMode and pageLayout (meta in the document, props of <Document>): the PDF producer (default Inkoxide <version>), what the viewer shows when it opens the PDF (no panel, the bookmarks, thumbnails or full screen; by default the bookmarks when there are any, as before), and how it lays out the pages (one or two pages, or one or two scrolling columns).
• inkoxide (Rust): validate_without_images, which validates a document without looking up its image ids, as the Node validate does when it is given no images.

Changed

• A URL entry in remoteImages.allow is matched by origin and path instead of as a string prefix: it allows URLs with the same scheme, host and port, and, when it has a path, that path and the paths under it (https://cdn.example.com/img allows /img/logo.png, not /imgs/logo.png). Entries such as https://cdn.example.com/ work as before.
• The inkoxide CLI's validate refuses --full-fonts and --hyphenation, which it accepted and ignored; render and bench take them as before.
• The published @inkoxide/tailwind no longer declares "sideEffects": false: importing it loads @tailwindcss/node, which registers Node module resolution hooks.
• The @inkoxide/tailwind README documents DEFAULT_THEME_CSS, every initTailwind option, setTailwindStrict, tw.warm and tw.cacheSize.
• Lengths in style and in classes take the same syntax, read by one reader in @inkoxide/style. style now takes calc() ('calc(10mm + 1em)'), units in any case ('5PX') and exponents ('1e1pt'), and em, vw and vh in a transform or transformOrigin string. Classes now take em, vw and vh (w-[2em], h-[10vh]; tw() takes the font and page sizes as a second argument) and a space before the unit (w-[5_pt]). A number too large for a float ('1e999pt') is an error in both, as is a bare infinity (w-[infinity]), which CSS takes only inside calc(), and style length errors name the property (width: 3ex (unsupported unit "ex")). textDecoration and objectFit in style are read as their classes are, and text-decoration-line in a class takes both lines (underline line-through), as style does.

Deprecated

• @inkoxide/style: Reader, ENUMS, EnumKey, evalDim, Dim, substituteVars and parseFontFamily, which only @inkoxide/tailwind uses. They moved to @inkoxide/style/internal, which is for Inkoxide's own packages and not covered by semver, and will be removed from the main entry.
• TwStyle and TwKey (from @inkoxide/style and @inkoxide/tailwind) are renamed FlatStyle and FlatStyleKey: style props build this style too, not only classes. The old names stay as aliases for now.
• @inkoxide/tailwind: TailwindCompiler, which wraps Tailwind's unstable design-system API and which tw() cannot use (set a theme with initTailwind({ css })), and SUPPORTED, UNSUPPORTED and SupportedFamily, the data of the Tailwind support table. They will be removed from the package's exports.
• The default Tailwind theme's colours ink, ink-muted, brand, field, field-line, rule and head (bg-brand, text-ink, …), made for the engine's test documents, will be removed from it. Set them in your own theme (initTailwind({ css })) to keep using them.
• @inkoxide/react: FontRegistry.loadDirectory and the file field of FontFace that it reads. Read the font files yourself and pass their bytes to FontRegistry.register; @inkoxide/render now loads its bundled fonts that way.
• @inkoxide/react: FontRegistry.families(), which nothing uses.

Fixed

• The examples in the @inkoxide/render README run when copied into a new project and started with npx tsx, as the README says: like the quick start, they name the JSX runtime and end in a plain renderToFile call, without a top-level await. The files in examples/ render their PDF on every Node.js 22, not only on 22.18 and later, also when started through a symlinked path such as /tmp on macOS.
• validate decodes the images a document uses, so an image that does not decode is INVALID_IMAGE at its path. Until now only the header was read: a corrupt or truncated PNG passed validation and failed the render with IMAGE_ERROR and no path. A JPEG is still embedded without decoding, but its structure is checked: a JPEG cut short, or coded in a way PDF readers cannot show (lossless, hierarchical or arithmetic), is INVALID_IMAGE. The decode is cached, so the render that follows does not decode again.
• Node: validate without images found nothing past 100 image references. It counted the UNKNOWN_IMAGE errors it then dropped against the 100-error cap; it now skips the image lookups instead.
• Node: threads and compressionLevel that are not integers in range (threads 1–256, compressionLevel 0–9) are INVALID_ARGUMENT. They were converted: threads: -1 started a 256-thread pool, and 1.5, NaN or 2 ** 32 + 3 were truncated or wrapped. An invalid creationDate is INVALID_ARGUMENT too, like every other bad option, not the document code INVALID_VALUE. @inkoxide/render reports a bad threads or creationDate as ENGINE_REJECTED (400) at the option's path (options.threads); threads: 0 was an INTERNAL error (500).
• @inkoxide/render: imageTimeoutMs, remoteImages.timeoutMs and the maxBytes of remoteImages and localImages must be numbers from 0 (Infinity included); another value fails the render with ENGINE_REJECTED at its path before any image loads. A NaN or negative timeout failed every image at once, and a NaN maxBytes lifted the limit. A fractional timeout is rounded up to a whole millisecond: remoteImages.timeoutMs: 1.5 failed every remote image with a RangeError message.
• @inkoxide/render: a remote image answered with a 3xx status that is not a redirect (304) fails with HTTP 304, not HTTP 304, and redirects are not followed.
• Node: InkoxideError no longer has an undocumented detail property (the same text as message).
• Rust: the RenderOptions::threads docs state that a pool has at most 256 threads and that Some(0) renders on the calling thread, as Some(1) does.
• A transform function with two keys or none ({ translate: [1, 2], rotate: 5 }, {}), and an array with more items than its fixed length (a five-item colour, a three-item transformOrigin), are INVALID_VALUE at their path. They were PARSE_ERROR ("not well-formed JSON") with no path.
• JSON and MessagePack report a bad version alike: a number other than 1 (2, 2.5) is UNSUPPORTED_VERSION, and a version that is not a number ("1", true) is INVALID_TYPE. JSON reported "1" as an unsupported version, and MessagePack reported 2.5 as a wrong type.
• Validation follows the schema more closely (see the schema changelog): an integer past the engine's integer type is OUT_OF_RANGE, not INVALID_VALUE; ".5%", "5.%", ".5fr" and "-0fr" are rejected, as the schema rejects them; a "0fr" table column is OUT_OF_RANGE; and an empty or too long link or bookmark title is INVALID_VALUE, like an id of the wrong length.
• @inkoxide/schema types: a transform function or a grid track object takes the keys of one form only, so { translate: [1, 2], rotate: 5 } no longer type-checks.
• The inkoxide CLI printed a validation error's code twice (UNKNOWN_FONT UNKNOWN_FONT at …).
• A PageBreak, break="page-before" or break="page-after" inside a View that fits on the page starts a new page; it was ignored. It also breaks inside break="avoid" (wrap={false}), as in CSS, and a break before a View's first child takes the View to the new page instead of leaving its top padding behind. Inside a flex-row, grid, wrapping or reversed View, and inside an absolutely positioned, rotated or transformed element, where it did nothing, it is now an error, as is break="page-before" or break="page-after" on an absolutely positioned element.
• A page break at the end of the content, or one with nothing above it on its page (at the top of the first page, below a top margin), no longer adds a blank page.
• An absolutely positioned element of the page body written after a page break is placed from the top of the body, like one written first; it moved with the break and could be cut across two pages.
• A flex-row, grid or wrapping View taller than a page splits between the lines of its children, each column continuing on the next page, and a break="avoid" element taller than a page splits like any other; both were cut through a line of text at the page edge.
• Fixed elements in the body are painted in document order and by zIndex, as without fixed; nested ones were painted in the wrong order.
• A table cell's height is a minimum, as in CSS: the row grows to fit the cell's content. Until now it fixed the row's height, and taller content ran over the next row.
• Styles a table cell ignored are validation errors (STYLE_NOT_APPLICABLE), like transform and zIndex already were: width, minWidth, maxWidth, maxHeight, margin, position, inset, alignSelf, justifySelf, flexGrow, flexShrink, flexBasis, gridRow, gridColumn, gridArea, overflow, opacity and rotate. They passed validation and had no effect, or, for minWidth and maxWidth, changed the width of the cell's text but not of its column, so the text ran into the next cell or wrapped in a narrow strip.
• Collapsed table borders (the default borderCollapse) keep their borderStyle: dashed and dotted cell borders were drawn solid. Where two borders of equal width meet, solid wins over dashed and dashed over dotted, as in CSS.
• A box whose first child has minPresenceAhead or break.before: "page" (or is a PageBreak) moves to the next page with that child, as CSS carries a break up to the parent. It left its empty top (padding and background) at the foot of the page before.
• A table whose first row is taller than a page starts on the current page and splits that row, as it already did for later rows. It moved whole to a new page, leaving the rest of the page empty.
• Percentage heights of a Page's children (height: '50%', minHeight, maxHeight) are of the page content height. They behaved as auto.
• Text collapses only spaces, tabs and line breaks, as in CSS. Thin, em, figure, ideographic and other space characters keep their own width, and the non-breaking ones no longer allow a line break.
• Tabs in pre and pre-wrap text advance to the next tab stop, as CSS tab-size: 8: stops are 8 spaces of the font apart from the start of the line, so tab-separated columns line up in any font. Each tab was four spaces.
• A box sized to the min-content width of hyphenated text leaves room for the hyphen; the hyphen was drawn outside it.
• The docs say how minPresenceAhead, percentage gaps and relative top/left offsets work.
• A creation date with an offset under an hour west of UTC (-00:30) is written with its sign in the PDF information dictionary; it was written east of UTC, an hour off the XMP date that PDF/A requires it to match.
• Registering a font collection (.ttc) fails with FONT_ERROR. It was accepted, only its first face could be used, and with subsetFonts: false the whole collection was embedded where the PDF needs a single TrueType program.
• An SVG image whose width or height is under 0.00001 px, or whose viewBox width or height is, fails with INVALID_IMAGE at its path (a nested SVG image is left out). Scaling it up made the PDF writer output inf, or numbers too large for PDF readers, in the image's matrix.
• Huge but finite numbers in an SVG image (transform="scale(1e30)", a gradient, mask, pattern or shape at 1e30) no longer make an invalid PDF. The PDF writer wrote them as digits only, integers far past the 32 bits PDF readers parse, which they treat as errors or null. Every number the writer emits, in page content, SVG drawings, annotations and dictionaries, is now at most ±10¹¹.
• borderRadius rounds an image's corners without overflow: hidden: the image is clipped to the rounded content box, as in CSS.
• A select field embeds the glyphs of the common Latin range and of every option, as a text field does, so a viewer can show the option picked; it embedded only those of its value.
• The mark of a checkbox or radio button takes its size from size, centred in the widget; it grew with the widget box.
• A checkbox or radio button without a width or height keeps its size + 2 pt square where its container would stretch it (as in a column, by default); it stretched across the container.
• A radio button whose value is Off, or longer than 127 bytes, is no longer written with a broken appearance state: such a group names its states by position and lists its values in /Opt. A checked Off button showed as unselected.
• Links and form fields inside a box with transform or rotate are clickable where the box is drawn: their areas follow the transform, and a field's appearance turns and scales with it. They stayed at the untransformed position.
• An SVG with a viewBox drawn with fit: fill (the default) into a box of another shape keeps its proportions, as in CSS: the box becomes its viewport, and its preserveAspectRatio (centred and whole by default) places the drawing. It was stretched to the box, so an <Svg> given width: '100%' came out squashed.
• An SVG element with a filter (a drop shadow, a blur) is drawn without the filter; it was left out with its children, so a logo with a shadow showed as a blank box.
• SVG gradients with spreadMethod="repeat" or "reflect" repeat or mirror their stops over what they paint; they were drawn as pad, one ramp and then a flat colour.
• GIF and WebP images embedded in an SVG as data: URLs are drawn; they were left out.
• An SVG fails with INVALID_IMAGE when an SVG image nested in it has text, as it does with text of its own, and when an image embedded in it is over 50 megapixels; both were left out silently. The guide lists what SVG drawing does not support.
• Grid placement: a gridColumn or gridRow with start, end and span runs from start to end, as in CSS; the engine used start and span and ignored end. In Tailwind, a span after the slash is kept (col-[2/span_3] was one column at line 2), col-span-3 col-start-1 col-end-3 is 1 / 3, not three columns, and a span at the end is ignored after one at the start (col-start-[span_2] col-end-[span_3] is two columns).
• Tailwind themes: initTailwind({ css }) run alongside init() or another initTailwind() keeps its theme; whichever load finished last used to win, so the default theme could replace it.
• flex: a lone length is the basis, as in CSS: flex: '30%' and flex-[30%] are 1 1 30%. The style prop rejected it and the class read it as a grow of 0.3. Grow and shrink with a unit are an unsupported value.
• Reading values: an unsupported Tailwind value always names the CSS property (leading-[abc], rotate-[abc], p-[1pt_2pt_3pt_4pt_5pt], m-[var(--nope)]), and parseTransform throws UnsupportedValueError for a bad angle (rotate(1grad)). rotate-none works, and lengths above 10000pt are no longer cut to 10000pt (h-[12000pt]).
• Tailwind mapping: a class or style value outside what the engine takes fails where it is read, naming the class: line-clamp-0, line-clamp-[2.5], opacity-[1.5], col-span-0, aspect-[0], a skew of ±90deg or more, and a percentage or negative grow or shrink (grow-[30%], shrink-[-1]), which CSS rejects. grid-flow-dense works. Switching strict mode on checks class strings cached while it was off. Only selector problems that style children suggest gap; container says that media queries have no meaning in a PDF.
• Style values: transformOrigin: 'center left' and 'center right' work, and names such as toString are not taken as keywords by transformOrigin or fontWeight. Colour keywords are case-insensitive ('Transparent').
• Docs: the Fonts section and the Tailwind support table say that font-serif is Noto Sans, since no serif face is bundled, and the @inkoxide/schema README's ajv example type-checks with module: nodenext.
• A component that suspends (use() of a promise, a lazy component) fails the render with a template error that names it (a lazy component by its displayName, a render prop by its element), or the <Suspense> boundary it is in, and says that templates cannot wait for data. Without a boundary the error blamed a missing <Document>; with one, the PDF showed the fallback and the process crashed shortly afterwards.
• A later border, borderStyle or borderRadius for every side, in a style array or over className, replaces the per-side styles and per-corner radii set before it, and a per-corner borderRadius object keeps the corners it does not name instead of setting them to 0.
• @inkoxide/react errors for a style key an element does not take (maxLines on a View, padding on a Row or an inline Text) have kind 'props' and name the style when the key comes from style; only a key from className is kind 'tailwind', with the class. A string directly in a Table, Row or Document says where it belongs (a Cell, a Page) instead of suggesting a Text, which is not allowed there either. The remote-image error of @inkoxide/react names its own option, remoteImages.allow, and only @inkoxide/render adds the INKOXIDE_REMOTE_IMAGES variable, for every refused URL or request.
• Percentage padding on a Page (style={{ padding: '10%' }}, p-[10%]) is a share of the page width on every side, as in CSS, instead of being dropped, which also left the header and footer unaligned. A percentage minimum height on a Row (min-h-[10%]), which has no table height to resolve against, is a template error instead of being dropped.
• A Text or Link inside a Text with id, bookmark, pages, render, dir, orphans, widows, break, wrap={false} or minPresenceAhead is a template error that names the prop; these need a paragraph of their own and were dropped. A run in another lang inside a hyphenated paragraph is no longer hyphenated with the paragraph's patterns.
• textTransform with a lang that JavaScript does not take as a language tag (en_US) cases the text by the default rules instead of failing with an internal error.
• truncate, line-clamp-*, maxLines and ellipsis on a Page, Row or Spacer are a template error, as on other elements, instead of doing nothing; a negative numeric flex (style={{ flex: -1 }}) is rejected where the style is read, like flex: '-1', and so is a negative or non-numeric flexGrow or flexShrink.
• ClipPath and Defs have exported props types, ClipPathProps and DefsProps (also from @inkoxide/render), and ClipPath takes clipPathUnits.
• @inkoxide/render: a remote image that times out or drops its connection after the headers fails the render with IMAGE_FETCH_FAILED, as one that fails before them does, instead of a raw TimeoutError or TypeError. remoteImages.timeoutMs takes Infinity (no limit) and values past what a timer holds, as imageTimeoutMs does, instead of throwing a RangeError. A redirect from an allowed URL, still not followed, fails with HTTP 302, and redirects are not followed instead of fetch failed, and the guide and SECURITY.md say so.
• @inkoxide/render: Font.register fetches a URL with a 30-second limit for the whole download and a 50 MiB size limit, through the same download code as remote images. A font host that never answered held up every render in the process for up to five minutes, or for good when it sent bytes slowly; now the render that loads the font fails with INVALID_FONT (timed out after 30000 ms). The guide lists http: URLs, which were already fetched.
• @inkoxide/render/templates: renderTree called before init() has finished, or while fonts added with Font.register are not loaded yet, throws an INTERNAL RenderError that says to call await init(), instead of failing with No fonts are registered, pointing to functions the package does not export, or building a tree without those fonts. renderSettled runs init() itself. The guide says that renderTree needs init() first.
• @inkoxide/render/templates: renderDocument takes images from the images option as well as from its images argument, which it ignored. generate resolves with images, the images the document was rendered with by id (and renderSettled with the same), so a stored result.document whose images were bytes, files, URLs or functions renders again with renderDocument(result.document, result.images); until now the ids the tree made up for them (image-0) failed with UNKNOWN_IMAGE.
• Font.register tells faces apart by family, weight and style, and compares byte sources by their bytes. It throws for a face the bundled fonts have (Inter 400 from another file was accepted and never used), for a family whose font id another family has (Brand-Two after Brand Two was skipped without a word), for a different font of the same byte length (was ignored), and for a src that is not a path, a URL or bytes (null failed the next render with a TypeError). A registration that throws adds none of its faces. The guide gives font weights as 1–1000, the range the code accepts.
• @inkoxide/render: renderToBuffer(null), or a string or a number in place of an element, fails with a TEMPLATE_ERROR RenderError instead of a TypeError.
• @inkoxide/render/templates: generate's timings.engineMs no longer includes the tree rebuilds for the page count, and treeMs counts each rebuild once, so the stages add up. renderSettled resolves with that rebuild time as treeMs. GenerateOptions is the same type as RenderToBufferOptions.
• @inkoxide/render: the start-up error for missing fonts says what INKOXIDE_ASSETS_DIR must point to, and the guide's FAQ explains when to set it (a bundled deployment).
• A font whose GSUB or GPOS lookups point to a missing or malformed coverage table is rejected with FONT_ERROR when it is registered. It registered, and the first render that shaped text with it panicked in the shaper: a panic in Rust, an INTERNAL error in Node. The Rust render now returns any panic as an error: FONT_ERROR naming the font when it happens while shaping, INTERNAL otherwise.

Added

• @inkoxide/style, the style values that @inkoxide/react and @inkoxide/tailwind share: the readers of CSS lengths, colours, flex, transforms, transform origins and object positions, and the style object type. They moved out of @inkoxide/tailwind, which still exports the same names.

Changed

• Page numbers in the page body (<PageNumber /> and <TotalPages /> in a Text) are laid out with their own digits, as in headers and footers. The text wraps, justifies and sizes its box at the width of the numbers of the page it lands on, and the page breaks are worked out again when those numbers move it. Until now the body kept room for a three-digit number: a box sized by its text was too wide for a short number, and a number of four digits or more could overflow it. Text the body repeats on several pages (a table's header rows) still keeps that room, since each page draws its own digits in it.
• Tailwind is optional. @inkoxide/render and @inkoxide/react no longer install @inkoxide/tailwind: they load it when it is installed, for className. Templates styled with style alone need nothing more, and the install is about 10 MB smaller (no Tailwind compiler, Lightning CSS or PostCSS). Upgrading: if you use className, run npm install @inkoxide/tailwind; without it, a className fails with a template error that says so. renderToTree in @inkoxide/react loads Tailwind itself, as @inkoxide/render does; before the synchronous renderTemplate, call the new loadTailwind() once.

Added

• @inkoxide/render/templates, a second entry of @inkoxide/render for serving templates by id with a zod schema for their data: generate, parseData, renderTree, renderSettled, renderDocument and the types TemplateLike, GenerateOptions, RenderOpts, RenderResult, Timings and TreeResult. The guide documents it under Serving templates.
• The @inkoxide/render guide documents the rest of what the package exports: usePage, Field, version, engineStatus and countPages (health checks), the RenderError fields className, engineCode and issues and its JSON form, the exported types, the Document props creator, creationDate and fallbackFonts, and pages on elements of the page body, with negative page numbers counting from the end.
• @inkoxide/tailwind exports UnsupportedValueError, which parseTransform, parseOrigin and parseObjectPosition throw for a value the engine cannot express.
• @inkoxide/tailwind exports the CSS value helpers that @inkoxide/react shares with it: PT_PER_UNIT, parseFlex, round, splitTopLevel, BORDER_STYLES and OBJECT_FITS.
• @inkoxide/react exports imageSource and its ImageSource type, remoteRefused and innermostComponent, which @inkoxide/render uses, and takes the tree option remoteImagesElsewhere, another place the caller reads the remote allowlist from, which the error for a refused URL names. HOST_NAME is typed by host type (Record<HostType, string>).

Changed

• @inkoxide/render exports only what its guide documents, a list now pinned by a test. This breaks only code that used undocumented names:
  • generate, parseData, renderTree, renderSettled, renderDocument, TemplateLike, GenerateOptions, RenderOpts, RenderResult and Timings moved to @inkoxide/render/templates.
  • renderTemplate, renderToTree, assertValidTree, validateTree, SchemaProblem, TemplateError, TemplateErrorKind, fonts, FontRegistry, FontFace, ResolvedFont, HOST, HOST_NAME, HostType, isImagePath, remoteAllowed, RemoteImagePolicy, PendingImage, parsePath, fontWeightValue, TreeOptions, TreeResult and Located are no longer re-exported; import them from @inkoxide/react (TreeResult is also in @inkoxide/render/templates).
  • SCHEMA_VERSION is no longer re-exported; import it from @inkoxide/schema, or read version().schema.
  • initEngine, assetsDir, DEFAULT_FACES and RenderErrorInit are no longer exported: init() starts the engine, and INKOXIDE_ASSETS_DIR still sets where the bundled fonts are read from.
  • The deprecated aliases StudioError and StudioErrorCode are removed; use RenderError and RenderErrorCode.
• The flex shorthand reads the same in style and in Tailwind classes: style={{ flex: '1 auto' }} sets grow and basis, as flex-[1_auto] does, and flex-[initial] works as flex: 'initial' does. A lone grow in a class is rounded to six decimals like every other value. An empty flex ('') is an error instead of a grow of 0, and a negative grow or shrink (flex-[-1]) is an unsupported value where the class or style is read, not a schema error later.

Security

• SVG style attributes and sheets are held to a limit on what the CSS parser does with every unitless number and # as well as every declaration: it scans the text from its start each time, so a style with a long stroke-dasharray used seconds to minutes of CPU. Found by a new structure-aware SVG fuzz target (render_svg_tree).

Fixed

• A table with break: { fixed: true } in the flow repeats whole on every page: its row and cell backgrounds and borders were painted only on its first page, and the later pages showed only the cells' content.
• A table with headerRows that starts at the top of a page no longer paints its header twice on that page (a translucent header background came out darker, and text extraction read the header twice).

Security

• SVG images are held to their limits as the SVG converter expands them: nested SVG images and every copy of them, markers at every vertex of every shape, references however they are written, style sheet rules and the declarations they copy, inherited attributes and embedded raster pixels all count. Entities that expand to more than 1 MiB, href chains that loop and radii or path coordinates beyond 10⁷ are refused. A small SVG could otherwise use minutes of CPU and gigabytes of memory. Each raster image in an SVG is embedded in the PDF once.

Fixed

• threads: 1 runs the whole render on the calling thread (in Node, the libuv thread that runs it), as documented. Every one-thread render used to queue for the same worker thread, so concurrent renders ran one at a time.
• Every failure of renderToBuffer, renderToStream, renderToFile and init is a RenderError. An engine that cannot start and a PDF that renderToFile cannot write are INTERNAL; a render prop that throws on a later pass is TEMPLATE_ERROR. The guide's error table lists INTERNAL, and gives TEMPLATE_ERROR as the code of an invalid prop.
• Font.register reads a file: URL given as a string ('file:///fonts/Lora.ttf'), not only as a URL.
• A font from Font.register that cannot be loaded no longer keeps the fonts registered with it from loading. The render still fails with INVALID_FONT, and the next one can use them.
• inkoxide no longer exports its __testPanic test hook, which was never public API.
• <Svg fixed> and <Svg debug> no longer write fixed and debug attributes into the drawing.
• The @inkoxide/react renderer gives React its real version, from its package.json, instead of 0.1.0.
• An image over the 50-megapixel limit fails validation with IMAGE_TOO_LARGE, as documented. It was reported as INVALID_IMAGE.
• A document with pages: [] fails validation with INVALID_VALUE at pages, as the schema requires at least one page. It rendered a PDF with no pages, which viewers reject.
• Validation enforces the remaining bounds of the schema: an id (of a node, row, cell, font or image, or a font named by a run, a field or fallbackFonts) is 1 to 256 characters and a font family is not empty (INVALID_VALUE), and a grid span is at least 1 (OUT_OF_RANGE; span: 0 was laid out as 1). The schema states the engine's bounds of grid lines: within ±32767 and not 0, and a span of at most 65535.
• The documentation states that validate returns at most 100 problems, and only the first when the document's structure cannot be read. The schema, SCHEMA.md and API.md describe the rules the engine applies beyond the schema's shapes: break and pageBreak in headers, footers and table cells, margins that leave no room for content, and repeated form field names.

Changed

• Hyphenation patterns are registered for the whole language tag. Patterns for en-GB no longer replace those for en-US; text uses the patterns of its own tag, else of the nearest less specific one (en-GB, then en), else the built-in ones. Three-letter languages such as haw or fil can be registered. Patterns registered for a region now serve only that region: register for en (not en-US) to cover every English lang. @inkoxide/render registers its US English patterns for en, so they still serve every English lang; engineStatus().hyphenation lists them as en.

Removed

• inkoxide::debug_raw_parse_error, a hidden test hook that was never part of the API. The schema-parity check that used it is now a unit test inside the crate.

Repository

• Architecture lists every public item of the crate, and places parsing in validate, where it lives.

Added

• <Link>: a link as a component, next to href on Text and View. Inside a Text it is a linked run, elsewhere a box. src is an alias of href.
• Page sizes: the ISO A, B and C series, RA, SRA, Folio and ID-1, matched in any case; size={[width, height]}, size={[side]} and a single length for a square page.
• Image sources:
  • Files, read only from folders you allow with the localImages render option or INKOXIDE_LOCAL_IMAGES. Paths cannot leave those folders, through .. or symbolic links, and files are capped at 20 MiB by default.
  • Requests with a method, headers and a body: { uri, method, headers, body }, under the same allowlist and limits as URL strings.
  • Functions and promises that resolve to any source, with a timeout (imageTimeoutMs, 10 s by default).
  • ArrayBuffer bytes.
• Style keys:
  • objectFit on images, and textOverflow: 'ellipsis'.
  • textDecoration: 'line-through' and 'underline line-through', which draws the line-through, plus textDecorationColor, textDecorationStyle and textDecorationThickness.
  • The shorthands border, borderTop, borderRight, borderBottom and borderLeft, e.g. '1px solid #e5e7eb'.
• Units in style objects: pc, rem, em, vw and vh.
• Fonts:
  • WOFF and WOFF2 files, in Font.register, registerFont and the CLI --fonts folders.
  • Font.registerHyphenationCallback and a hyphenationCallback prop on Text, to split words with your own function.
• renderToStream: the PDF as a Node Readable.
• fixed: an element placed directly in a Page with position: 'absolute' repeats on every page, placed against the page's content box, for watermarks, borders and page numbers. A negative zIndex puts it under the content.
• objectPosition on images, in style objects and as Tailwind object-* classes, places a fitted image in its box: keywords, percentages or lengths. objectFit also has its Tailwind classes now.
• debug: outlines the margin, border, padding and content boxes of an element and labels its size; on a Page or the Document, of every element. Labels are drawn, not text, so copying text from the PDF is unaffected.
• @inkoxide/schema: hyphenate on a text run, overriding its text node's setting for the run's words; objectPosition on images; debug on nodes, rows, cells and pages.

Changed

• An image src string that names an id you pass in images is always that image, even when it looks like a URL. Such strings used to be fetched.
• Page size strings are checked in full: "A4-landscape-x" is an error instead of A4 landscape.
• Every length, percentage and factor in a document has a range (percentages within ±10000%, points within ±1000000), and a value outside it is OUT_OF_RANGE. In React, an infinite or NaN style value is an error instead of being dropped.
• A fixed, absolutely positioned child of a page in a JSON document is placed against the page's content box on every page. Its insets used to be resolved against the whole flow, so bottom and percentages put it in the wrong place.

Fixed

• Page numbers in headers and footers are laid out with their real digits, so centred and right-aligned numbers line up, and documents of 1,000 pages or more no longer overflow the space.
• A panic while registering a font or hyphenation patterns is reported as an INTERNAL error instead of ending the process.
• Huge percentages, for example in width, margin or a translate, no longer write inf or NaN into the PDF, which made it invalid. The PDF writer also never writes a non-finite number, from layout or from an SVG image.

Breaking: ES modules only

inkoxide 0.2.0 and @inkoxide/schema 2.0.0 are ES modules and need Node.js 22 or later, like the React packages already did. Replace require('inkoxide') with import … from 'inkoxide'. @inkoxide/schema 2.0.0 still describes document schema version 1; documents do not change.

Dependency updates

@inkoxide/tailwind 0.1.1, @inkoxide/react 0.1.1 and @inkoxide/render 0.1.2 depend on the releases above. The @inkoxide/render README now shows the project setup the quick start needs.
