Hi, I used something like that in one of my projects:

#(define-markup-command (epsfile-mm layout props axis size file-name)
  (number? number? string?)
  (let* ((o-s (ly:output-def-lookup layout 'output-scale))
         (scaled-size (abs (/ size o-s))))
  (if (ly:get-option 'safe)
      (interpret-markup layout props "not allowed in safe")
      (eps-file->stencil axis scaled-size file-name)
      )))

It works like \epsfile but assumes the dimensions are in mm.

HTH,

Marc
