Re: [O] Export attributes for babel blocks

[Juan Amiguet]

Thomas thank you for your answer,

I was thinking more of how to modify babel so that it would generate the results block with the relevant exporter attribute parameters so that it play nicely.

That is, the results block contains the directive it needs at the moment the #+results block is bare and has no extra information for latex to pick up and format correctly.

Kind regards.

Dot doesn't know anything about the linewidth you might be using in
LaTeX.  LaTeX will take any image and reproduce it at .5/linewidth,
regardless of dot settings.

The :cmdline header argument for dot is documented here:
http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-dot.html

You can find links to the dot command line arguments.  Babel gives you
full access to the dot command line.

hth,
Tom
