I'd accept this if it were not for the fact that Finale seems to handle this perfectly. I've never experienced any sticking out barlines in Finale pdfs, neither on screen nor in print (i can send you some if you want). Also, the thickness of the stems and barlines is consistent in Finale pdfs (i.e. it looks like second image from here http://lists.gnu.org/archive/html/lilypond-devel/2007-07/msg00076.html while Lily output looks like first one). I'd say that the fact that Finale does something this basic better than LilyPond is a serious insult to us, given how much Finale sucks in these matters (for example in flag attachment, see attached). > The one-pixel error is very noticeable on-screen due to > low-resolution, but on a 1200dpi printer, a single dot error is about > 0.02 mm, ie. not noticeable. I'm not sure whether you are referring to how it looked before your patch or how it looks after it. Before your patch it was certainly noticeable enough - even my friend Luke, who doesn't care that much about the details, said it irked him. As for how it looks after your patch - I hoped to be able to do some prints on my choir's printer to see how things looks like now, but it ran out of toner - new cartridge should be available in next week. Besides, many printers have resolutions lower than 1200dpi. cheers, Janek
