pdfium-syntax-rendering

What this skill covers

Rendering turns a PdfPage into a raster image. The pipeline is fixed:

PdfPage
  -> render_with_config(&PdfRenderConfig)   (or render(width, height, rotation))
  -> PdfBitmap
  -> as_image()        -> image::DynamicImage
     as_rgba_bytes()   -> Vec<u8>  (RGBA, normalized)
     as_raw_bytes()    -> Vec<u8>  (native PDFium byte order)
