Unfortunately, you seem to have attached it as text/enriched and it is
messed up. Can you please attach it as text/plain?

Thanks!

I attach it just in case.

Didn't know about enriched-mode - thanks!

But back to the original question: with the redefined
org-format-latex-header, I get errors (probably because the preview is
produced by running latex, whereas the redefined header seems to require
xetex). Without the redefined header, I get a preview which does *not*
have large margins. So the header is probably the culprit: I would start
deleting things from it, until the problem disappears. In particular,
the fullpage.sty settings look suspicious to me. Maybe somebody who has
set up previews with xe(la)tex can provide a more helpful answer
(doesn't that require code changes to org?)

Hi Nick,

Thanks you for your help.

Finally I found a solution by referring the examples in texample.net.
I just replaced the \documentclass{article} to
 documentclass[varwidth]{standalone},
then it works perfectly.

I am not familiar enriched-mode, too.
It is also very strange that why i can not receive the email in my gmail...

Thank you anyway.

Thanks for sharing this trick, hard to find, so even more valuable
when made public.

Preview tikz in org-mode (reduce margins of produced images)

[Leu Zhe]

[-- Attachment #1: Type: text/plain, Size: 565 bytes --]

Hi, everyone!

I always use org-preview-latex-fragment command to preview the LaTeX code,
which is awesome.
It can effectively crop and suit the size of produced png to the content.

However, recently I start to preview some tikz code.
I can greatly produce the good results except one problem:
The preview can never reduce the spare margin of the produced images, which
left large blank space there. However, when I preview other LaTeX code
after deleting tikz preamble, everything is fine.

So is there anyone who has some idea to reduce the large margins?

It helps if you provide a small example: otherwise, even if one is
willing to take a stab at it, one has to create one from scratch. Given
that just about all of us have limited time, that reduces the
probability that you will get an answer.
