Subject: Creating Image White Text on Black Background
Date: Thu, 6 Aug 2020 01:32:19 +0200	[thread overview]
Message-ID: <trinity-e8e238e3-c63d-4447-859c-4ced3e1cf39f-1596670339856@3c-app-mailcom-bs02> (raw)

Am trying to have the latex image to output White Text on Black Background

Currently I have the following Code:

#+HEADER: :exports results :file equation.png
#+BEGIN_SRC latex :exports results :file equation.png :imagemagick yes :iminoptions -density 300
$ x=\sqrt{b} $
For a spherical triangle with sides $a$, $b$, and $c$, and
opposite angles $\alpha$, $\beta$, and $\gamma$, we have:
$$\cos \alpha = -\cos \beta \cos \gamma +
\sin \beta \sin \gamma \cos \alpha \quad
\hbox{(Law of Cosines)}$$
and:
$$\tan {\alpha \over 2} = \sqrt{
{- \cos \sigma \cdot \cos(\sigma - \alpha)} \over
{\cos (\sigma - \beta) \cdot \cos (\sigma - \gamma)}},\quad
\hbox{where $\sigma = {1 \over 2}(a+b+c)$}$$
We also have:$$\sin x = {{e^{ix}-e^{-ix}}\over 2i}$$
and:
$$\int _0 ^\infty {{\sin ax \sin bx}\over{x^2}}\,dx
% The \, above produces a thin space
= {\pi a\over 2}, \quad \hbox{if $a < b$}$$
#+END_SRC
