generating graphic examples

[Josh Nichols]

I want to be able to generate graphic musical examples without getting it
formatted on a giant paper-formatted .pdf or .png.  How do I accomplish
this?


I cannot find anything in the manual which allows this.

add this block

\paper{
  indent=0\mm
  line-width=120\mm
  oddFooterMarkup=##f
  oddHeaderMarkup=##f
  bookTitleMarkup = ##f
  scoreTitleMarkup = ##f
}

and call lilypond this way on myfile.ly:

lilypond -dbackend=eps -dno-gs-load-fonts -dinclude-eps-fonts --png myfile.ly

 I cannot find anything in the manual which allows this.

I assume you basically want to trim your output to the really used space.
I guess there should be an option to do so, since it's done for the 
snippets in the documentation, and it might well be the clip-systems 
option. However, this one does exactly nothing for me (2.12.1), or I 
just can't use it correctly.


If you have ImageMagick ready, for PNGs you can just call
convert -trim original.png trimmed.png

If you want trimmed PDF and/or EPS files and are on one of the common 
Unices with ImageMagick/GraphicsMagick, GhostScript and xpdf-utils 
installed, have a look at the attached Makefile.
Note that I don't simply use the above command for the PNGs, but convert 
the PDF to PNG instead; this way, the sizes of both images are exactly 
the same (up to the resolution).
If you remove the -l option from the ps2eps call in line 16, the PDF 
should be trimmed tight; with it, there is a white border of about 1pt 
around it.


I have no idea what this does to multipage files, by the way.

Josh,

If these other methods don't work for you, and if you're running Linux or
Mac OSX, then I have a bash script that does exactly what you want.  See
this thread for more info:
