Specific (and common) use-cases like drawing paths can be converted (by hand!), but for a general solution, you'd have to run the command through Ghostscript, dumping to PDF and then somehow translate the PDF back in to lilypond commands. It's not completely impossible, but a lot of work. -- Han-Wen Nienhuys - hanw...@gmail.com - http://www.xs4all.nl/~hanwen

The standard staff size is 20pt, so 5pt to a staffspace, which is 1.757mm -- Han-Wen Nienhuys - hanw...@gmail.com - http://www.xs4all.nl/~hanwen

I've managed to get this working, except that the border drawn runs off the page at right and bottom. I'm now faced with the challenge of finding out what the page size is in staff spaces - as I presume the \path command is speaking in staff spaces while the border box needs to be drawn within the edges of the page ...
