Okay, I translate
<lilypond fragment relative=2>
\key c \minor c4 es g2
</lilypond>
to
\paper {
raggedright = ##t
indent = 0\mm
}
\relative c'' {
\key c \minor c4 es g2
}
As I don't need a PDF, I used the command line
lilypond --safe --format=ps --preview --png FILE
However, in order to use ps2png, I had to patch lilylib.py (see
attachment). Is this patch okay? It replaces a re.match by re.search (as
the %%BoundingBox cannot be at the beginning of the file), and it adds
"-c showpage" to the gs command line (else I don't get BBoxes or PNGs).
Ciao,
Dscho
