That way you export to a vector format that looks superb in the final PDF. This requires a postprocessing step that I'm not sure how to integrate. From one of my Makefiles, I use this line to fix the EPS so that Latex can import it: sed -i -e 's/PS-Adobe-2.0/PS-Adobe-2.0 EPSF-1.2/1' $@ Comments?

I guess the best solution would actually be to allow a lisp function to do the formatting, and it should return the link to be used. then you can implement whatever is needed.

I think that rather than changing the specification of the dot block (which will break existing org files) we should create new block files. Either create a single graphviz file, which will accept an argument indicating which command to use, or create a new block type for each command. I'm not sure which of these approaches would be preferred... They should both require only small changes to your existing code. If we were starting from scratch my preference would be a single graphviz block type, however in order to maintain functionality for existing org-mode documents, in this case I would lean towards generating a block type for each command. I suppose we could support both options. any suggestions? I certainly agree that a change along these lines should be added to the version of org-exp-block.el distributed with org mode. Also, sorry about the delayed reply, I was waiting until I found the time to actually look over your attached files. >> >> >> My next question relates to using Graphviz between HTML and Latex >> export.

Possibly a something along the lines of a #+postprocessing: line immediately preceding the block. However that would be a general solution. If our goal is just to allow post processing in this instance, I believe that using defadvice would be the easiest hack. Make sure that the last statement in `org-export-blocks-format-dot' returns the file path, and then try something like the following... --8<---------------cut here---------------start------------->8--- (defadvice org-export-blocks-format-dot (around fix-eps-org-export-blocks-format-dot activate) "Fix graphviz eps output."

After that patch is applied, the code below[1] can be used to add a new block type which will automatically process blocks with dot then eps. For example the following block specification will create out-w-eps.eps and org-w-eps.pdf files on export. #+begin_dot-and-eps out-w-eps digraph test { a -> { b c d e }; e -> { f g h i }; }; #+end_dot-and-eps Cheers -- Eric [1] (defun org-export-blocks-format-dot-and-eps (body &rest headers) "Pass block BODY to the dot graphing utility creating an eps file which is then processed by eps to create a pdf.
