用可變字體從 HTML/XML 生成 PDF

BFO Publisher is a Java-based CSS layout engine developed by Big Faceless Organization (BFO) that converts HTML or XML styled with CSS into PDF documents. Built on top of the Big Faceless PDF Library, it supports advanced layout features, including modern CSS constructs like flexbox-1, SVG2, and MathML4, and it delivers archival quality outputs compliant with PDF/A, PDF/X and PDF/UA. Designed with a streaming architecture, it can generate very large documents efficiently while keeping memory usage low, and it is flexible for deployment both via its API and as a web‑service in local or cloud environments.

The BFO Publisher v1.4 update adds support for OpenType variable fonts, enabling developers to embed and render fonts with adjustable weight, width, and other typographic axes from a single font file. These fonts are not supported in PDF format, so are converted into a static instance which gets embedded into the PDF. This reduces the need to manage multiple static font files, lowers output file sizes, and allows finer control over typography directly through CSS, leading to more precise and efficient design workflows when creating PDFs with BFO Publisher.
