def to_emf(document)
  metafile = Translation::EmfRenderer.call(document)
  Emf.serialize(metafile)
end

.to_svg(metafile, **options) ⇒ Object

Render an Emf::Model::Metafile to an SVG string.

Options:

namespace:  XML namespace prefix, e.g. "svg" (default: none)
width:      override viewport width (default: from metafile header)
height:     override viewport height
verbose:    print record-by-record dispatch to STDERR (default: false)
emf_plus:   attempt to render EMF+ records instead of EMF fallback
          (default: false — EMF+ is structured-parsed by emf but
          not yet rendered)
