Feature request: when outputting to a png file,
make
the background
transparent instead of white. (Or have an
option
to do this.)
This can already be done with the pngalpha device of
GhostScript.
Call LilyPond like this:
lilypond --png -dpixmap-format=pngalpha file.ly
best regards,

Thanks, Wilbert! I tried "lilypond -dhelp" to look
around for an option
like that but completely overlooked that one.

Ok, when I run lilypond from the command line with the following options
it works perfectly:
lilypond --png -dpixmap-format=pngalpha -dpreview test.ly
But when I run it from jedit using lilypondtool I get an error in the
lilypond console: "unrecognized option: foo" where foo is whatever
I put as the default arguments in the lilypondtool plugin options. I'm
putting the following in the textbox for "default arguments":
--png -dpixmap-format=pngalpha -dpreview
I don't get the error if I use a single argument like "--png", or
"dpreview".
-Jonathan
I think this is a bug in LilyPondTool, because it sends the whole
"default arguments" list as one argument to lilypond.
As a workaround you can try writing this to the Console window:
%lilypond --png -dpixmap-format=pngalpha -dpreview %buffer
