But it converts the PostScript to PDF using Ghostscript, and Ghostscript will both read and write PDF and PostScript, so it is quite likely that there are some instructions in Ghostscript's version of the PostScript language that would get converted into layer instructions in PDF. For example, we use the "pdfmark" command for generating embedded links. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
