[latex export/babel] pass arguments to \includegraphics from code blocks

[latex export/babel] pass arguments to \includegraphics from code blocks

[Jakob Schöttl]

Hi, I want to use code blocks to generate and include images of sheet music:

#+BEGIN_SRC lilypond :file test.png :exports results
\header{tagline=""}
{ a b c }
#+END_SRC

When doing a latex export the result is:

\begin{center}
\includegraphics[width=.9\linewidth]{test.png}
\end{center}

Is there a way to specify the arguments for \includegraphics? For 
example I want to change the display width.

Putting these lines above the code block have no effect:

#+ATTR_LATEX: :width 4cm
#+CAPTION: xxx

Maybe this requires a change in ob-lilypond.el to introduce new header 
arguments for the source block?

Regards, Jakob

What I do in such cases is evaluate the block and then add the caption and
attribute line above the #+RESULTS line:

--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC lilypond :file test.png :exports results
\header{tagline=""}
{ a b c }
#+END_SRC


#+ATTR_LATEX: :width 4cm
#+CAPTION: xxx
#+RESULTS:
[[file:test.png]]
--8<---------------cut here---------------end--------------->8---

Thank you, Nick! That's perfect.
