Does the README text of

  https://github.com/trueroad/extractpdfmark

help, together with the explanations of the `-O` option on

  
https://lilypond.org/doc/v2.25/Documentation/usage/basic-command_002dline-options-for-lilypond

?

Essentially, this option switches between the `show` and `glyphshow`
PostScript operators to access Emmentaler glyphs.  The former is
considered the 'standard' method for accessing glyphs in a PS file
(according to the GS developers); however, it needs properly set up
encoding vectors (which can't exceed a size of 256 glyphs each).  The
latter is slower, AFAIK, and apparently not as well supported with GS
(at least, we filed some bug reports, IIRC).
