You can't expect to mimic the spacing without doing the actual typesetting. Perhaps try running with -dbackend=scm and see whether you can find the necessary info in the dump. -- David Kastrup _______________________________________________ lilypond-devel mailing list [email protected] http://lists.gnu.org/mailman/listinfo/lilypond-devel
