Thank you, but now I always get:
! Illegal unit of measure (pt inserted).
<to be read again>
.
\figurewidth ->545.
03625pt
\dodostartlilypond ...expr (\LPscale \figurewidth
) \ifdim \FigWidth
>\localh...
from the code:
\def\LPscale{.6315789} % downscale the image
\ifvmode
\getfiguredimensions[\bufferprefix lilypond-\the\lily!
figures.pdf][]%
\leavevmode%
\newdimen\FigWidth
\FigWidth=\dimexpr(\LPscale\figurewidth)
\ifdim\FigWidth>\localhsize
\!!dimena=\localhsize
\advance\!!dimena by-\FigWidth
\noindent\hskip\!!dimena
\fi
\fi
\externalfigure[\lily!img][scale=\dimexpr(1000\LPscale)]%
\egroup%
What's wrong with \dimexpr{\SomeDef\SomeDim} ?
Some expansion problem?
(Sorry, I only try to patch the code, I didn't write it.)
