rpdfium

https://github.com/retsef/rpdfium

FFI bindings to Google's PDFium library, the same engine that powers Chrome's PDF viewer. Provides text extraction with character-level metadata (font, weight, origin, angle), vector path access, image extraction, annotations, AcroForm fields, page rendering, and pdfplumber-style table detection. Inspired by pypdfium2 and pdfplumber.
