Subject: :scale option in org-format-latex-options
Date: Sat, 13 Mar 2010 20:16:05 -0500 [thread overview]
Message-ID: <87wrxfya7e.fsf@stats.ox.ac.uk> (raw)
When creating png images of latex fragments in org-create-formula-image,
the :scale option in org-format-latex-options is not currently honoured
(it's commented out). My dvipng documentation says
-x num
Set the x magnification ratio to num/1000. Overrides the
magnification specified in the DVI file. Must be between 10
and 100000. It is recommended that you use standard magstep
values (1095, 1200, 1440, 1728, 2074, 2488, 2986, and so on)
to help reduce the total number of PK files generated. num
may be a real number, not an integer, for increased
precision.
I don't know what a magstep is, let alone a PK file, but it seems to
suggest something like the patch below. Is there any reason not to make
a change like this?

Also, this looks to me like a typo in the docstring of
org-format-latex-options, is that right?
