Re: [O] Block level specification for tex code html export method

[Alan Schmitt]

Hello Andreas,

I’m slowly catching up on the org mailing list, and I found your example
very interesting. I tried to run it and it does not seem to work here.
Here is what I did:
- I copied the code below to a file
- I evaluated the last block
- I made sure that latex was one of the org-babel-load-languages
  language
- I tried executing the first block, which generated this strange png

tree.png
Description: PNG image

- I exported both to html and pdf, and in both cases I would have
  a reference to the png instead of the svg/tikz code.

I’m afraid I’m missing a step. Do you see what I’m doing wrong?

Thanks,

Alan
