Hi John,

Is there any way to effect a "-fpng" using Scheme in an input file?

some time ago I asked for help for a similar problem.
This has been working for me:

% ---------------------------------------------
\version "2.24.1"
#(ly:set-option 'resolution 300)
#(ly:set-option 'tall-page-formats 'png)
{c'}
% ---------------------------------------------

But you will need Ly 2.23.5 or newer.
If you want to use lilypond-book-preamble.ly for cropped images, use
separate-page-formats instead of tall-page-formats.

Ah yes, that's right. For PNG output, normal output and separate-page output are more or less the same (since PNG files don't have multiple pages), so you can do that.
