The background/foreground are supposed to be changed by setting the
:buffer yes header and by customizing org-format-latex-options. I didn't
try it though, I'm happy with the [white] option to tikzpicture.
However, I noticed something odd. If I use the following headers
--8<---------------cut here---------------start------------->8---
#+header: :results raw :file py2tikz_sin.png
#+header: :imagemagick yes :fit yes :headers '("\\usepackage{tikz,pgfplots}")
#+header: :iminoptions -density 600 :imoutoptions -geometry 400
--8<---------------cut here---------------end--------------->8---
the png is transparent. If I remove the last line:
--8<---------------cut here---------------start------------->8---
#+header: :results raw :file py2tikz_sin.png
#+header: :imagemagick yes :fit yes :headers '("\\usepackage{tikz,pgfplots}")
--8<---------------cut here---------------end--------------->8---
I get the white background back, although in both cases, imagemagick is
used.
