Hi Haochen,
You can render svg from latex through org directly. Here is a complete
example including a tikz diagram that that works on my system (once I
tackle a bug in PGF [1]).
It renders
- png by default (and for inlining the image into the org document)
- nothing for latex (directly include the tikz code into the tex document)
- svg for html
--8<---------------cut here---------------start------------->8---
#+LATEX_HEADER: \usepackage{tikz}
First execute the second code block, to define the convenience macro
and to set the required new variables in ob-latex.el. Then export to
HTML and to pdf to see the tree exported as an SVG image and as
embedded tikz respectively.
* Tikz test
Here's a tree, exported to both html and pdf.
#+header: :file (by-backend (html "tree.svg") (latex "tree.tikz") (t
"tree.png"))
#+header: :imagemagick :iminoptions -density 600 :imoutoptions -geometry 800
#+header: :results file raw
#+header: :fit yes
#+begin_src latex
\usetikzlibrary{trees}
\begin{tikzpicture}
\node [circle, draw, fill=red!20] at (0,0) {1}
child { node [circle, draw, fill=blue!30] {2}
child { node [circle, draw, fill=green!30] {3} }
child { node [circle, draw, fill=yellow!30] {4} }};
\end{tikzpicture}
#+end_src
#+results:
[[file:tree.png]]
* COMMENT setup
#+begin_src emacs-lisp :results silent
(setq org-babel-latex-htlatex "htlatex")
(defmacro by-backend (&rest body)
`(case (if (boundp 'backend) (org-export-backend-name backend) nil) ,@body))
#+end_src
--8<---------------cut here---------------end--------------->8---
