Hi,

I've recently gotten into TikZ and love it. It is simply fantastic for
creating neat diagrams and other thingies.

One question... I created an org file with a flow chart in it and simply put
my TikZ code in between #+begin_latex and #+end_latex. This is fine when the
picture is in a document, but what if I want just a .png/jpg/eps/pdf output?
Is it possible to use babel or something else so that I can simply generate
a picture vs. needing it to be "in" the PDF output?

I can ask the PGF list as well, but this one is far more active and I know
some use TikZ here. I ask because sometimes in my notes I'd like to have the
code present but also be able to reuse my work elsewhere, like when I have
to present using powerpoint. It'd be nice to just grab the picture (like
what I do with gnuplot output) rather than generating a pdf just for the
TikZ pic, screenshot or gimp it down to size, and then be able to use it.

Does that make sense? It seems like babel would be perfect for this. It
already allows all the typical handles -- file output, what to export, etc.

Or does this already exist and I'm ignorant?

Thoughts?
John
