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). Werner
