I understand that the bigpdfs trick should to be fixed to use MuPDF instead of PDFDontUseFontObjectNum bug. >>Or, even so, should we take other methods (e.g. using non-embedded >>PDFs)? > > I'm not sure what other methods there would be.

There is a method of using font non-embedded PDF. In my experiment, it seems to work fine except TrueType fonts. It uses like `-c ".setpdfwrite << /NeverEmbed [ /Emmentaler-20 /TeXGyreSchola-Regular ] >> setdistillerparams"` instead of `-sOutputFile=filename.pdf`. I've made sample files `20170922_lilypond_eps_pdf_examples.tar.xz`. https://drive.google.com/file/d/0ByGBX3PDrqjsSFhVdXJfbjFjRlk/view?usp=sharing In the tarball: `fonts?-bigpdfs.eps`: EPS that is generated by LilyPond. `fonts?-bigpdfs-noembed.pdf`: No font embedded PDF that is generated by Ghostscript with `/NeverEmbed` parameter like above. `include-bigpdfs-noembed.pdf`: TeX outputted PDF that lacks LilyPond fonts. `include-bigpdfs-noembed-gse.pdf`: Finally PDF that is font embedded by Ghostscript. In `include-bigpdfs-noembed-gse.pdf`, OTF seems to be fine. However, some glyphs of TTF are broken. _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
