Hi James, thanks for that link.
> http://lilypond.org/doc/v2.15/Documentation/internals/index.html I'm about to write an interactive application for prima vista reading (in Java). I want to color played (and wrongly played) note heads, but the roundtrip from lilypond source to PDF is too slow for real-time. BTW, does anyone know such an open source project? My idea is to render the score once with all noteheads in black, and then quickly alter colors directly in the PDF, without going through Lilypond. Using PDF manipulation libraries, i want to locate specific note head PDF objects and change their color. Therefore, i need to know the specific PDF structure produced by Lilypond, some kind of schema like a class diagram. Of course it would be more convenient to use Lilypond's programmatic interfaces in-memory from Java, maybe the roundtrip could be fast enough for small scores. But i didn't investigate so far.
