Hi Mike, your function doesn't work for me. I get a wrong output (with "2.14.2" and "2.15.13") ->attached png And I'm still puzzled why I can't find the 'X-positions-property in "2.15.13" define-grob-properties.scm. But it is described in http://kainhofer.com/~lilypond/Documentation/internals-big-page.html#user-backend-properties . Cheers, Harm
