Authoring+ — what's new in 1.5.0

pdfnative 1.5.0 adds SVG <text> rendering, an opt-in layout debug overlay, and a typed markup annotation model. The Edge case demos exercise the math font, the page-labels reader and control-character hardening. Every demo below runs entirely in your browser and downloads a real PDF.

Also new in 1.5.0: a bundled math / technical-symbols font (lang 'math', auto-routed via script detection), the pdfnative/tools font compiler/parser (compileFontData / parseFontData), a page-labels reader (getPageLabels()), and annotation read/write on existing PDFs (getAnnotations() / addAnnotation()).

v1.5.0 features exercised here:
  • SVG <text> — text elements render as upright PDF text with text-anchor (start / middle / end) support, ideal for chart labels.
  • Layout debug overlay — layout: { debug: true } draws margin / content / cell boxes; inspectDocumentLayout() returns per-page block geometry.
  • Markup annotations — buildAnnotation() / buildAnnotationBody() for nine annotation types; getAnnotations() reads them back out of an existing PDF.
  • Math font — mathematical operators, arrows and letterlike symbols route to the bundled 'math' font automatically via script detection.
  • Page-labels reader — getPageLabels() round-trips the pageLabels number tree (Roman / decimal / prefixed) back into structured ranges.
  • Control-character hardening — NUL / BEL / form-feed / DEL embedded in text are dropped or escaped instead of emitting .notdef tofu.

All zero-dependency, all in the browser. The exact same code runs in Node.js, Deno, Bun and Web Workers.
