Yes, I found it worked fine for me. I had a silly problem with page
margins (searchng the forum for tikz/pgf will find my recent posts),
that was my fault but other than that the flow charts and mindmaps I
have done work well.

Let me add a qualifier: if you try to preview the image, then it does
not seem to work, but that seems to be a characteristic of tikz/pgf,
rather than org-mode.

Here's the experiment, should somebody care to try it:

o Start with a simple picture - the one waterloo posted earlier in
the month will do:

,----
| #+LaTeX_HEADER: \usepackage{tikz}
|
| * Draw
|
| \begin{tikzpicture}
| \draw (0,0) -- (10,0);
| \end{tikzpicture}
`----

o Export it to LaTeX with C-c C-e l.

o Process the latex file with pdflatex and view with xpdf - everything
is fine.

o Process the latex file with latex, producing a dvi file. View the dvi
file with xdvi: the picture is missing (and I get a Ghostscript error.)

o Process the dvi file to PS with dvips and view the resulting PS file:
the picture is there.

Since (I'm guessing) preview processes the dvi file with dvipng and
since the dvi file seems to have some kind of problem, preview does not
work.

HTH,
Nick

Yes, dvi file can not display tikz picture correctly .

Why do you use divpng? Auctex can preview tikz , it does not use dvipng.

Thanks

You mean preview-latex? Not for me: it just leaves the tikzpicture
environment
alone.

I use ditaa and graphviz. There are examples at

If you (or someone who wants tikz output to work) writes an exporter
that knows what to do with the tikz block I'm sure that can work.

Right now there is no such exporter available AFAIK.

[waterloo]

tikz is more power than ditaa and graphviz
.<http://doc.norang.ca/org-mode.html#sec-13.2>
I tikz's exporter will be supported in future version.

Thanks

Hi,

Adding support for a new block type is fairly easy for any tool that can
be called from the command line. If you would like to try this please
read the documentation of org-exp-blocks on worg [1] and follow the
example of the asymptote block type [2].

Best -- Eric

Sorry,

Please disregard this email, I didn't realize tikz/pgf was a package of
TeX macros and not an external tool. -- Eric

Thanks very much. asymptote's function is very much like tikz . I can use
asymptote.
Besides asymptote, I can use metapost.

I think this should work, but I believe the latex
files that is used to create the image does not have te right
usepackage statement.

Right now I am on a machine without dvipng, so I cannot try this:

1. pull from git
2. Instead of #+LaTeX_HEADER: \usepackage{tikz}, use

(setq org-export-latex-packages-alist '(("" "tikz))

because this customization will now also be seen by
the preview process.

I hope that then the preview will also work.
