Thank you for your suggestion.

Invoking 'lilypond -dresolution=1200 --png' results in the right 
dimensions, indeed. Thanks. I will use this. The image is not cropped 
automatically, so I now have to tune the page-height as well. And I have 
to set a small margin for the curly bracket of the PianoStaff. Otherwise 
it would be off the page.

The usage manual however (section 4.4) tells me to do this:
lilypond -dbackend=eps -dno-gs-load-fonts -dinclude-eps-fonts --png 
-dresolution=1200 figure.ly
That results in a png that is too wide. There seems another mechanism at 
work to determine size of resulting image. Cropping?

Thanks,
Peter
